Product Details

Dayton Audio APA150 150W Power Amplifier

Amplifiers today need to be multi-faceted to keep up with the task at hand, and versatility is the foundation upon which the Dayton Audio APA150 is built. When configured in stereo mode, amplification is provided to a pair of speakers for stereo or surround playback. Select bridge-mono mode and the APA150 is ready to power a center channel speaker, or a subwoofer/tactile transducer when used with the on-board low pass filter. Full-range line-level outputs allow for daisy chaining amplifiers for a multi-room whole house audio system or for bi-amp applications. The APA150's smaller chassis consumes less space than conventional amplifiers, making placement options virtually limitless.

Key features of the APA150 include high current, discrete power transistors (used in premium amp designs), a hefty toroidal power supply transformer, low-noise forced air cooling, a fully adjustable—and defeatable—electronic 50-150 Hz low-pass filter (18 dB/octave), and complete protection against electrical shorting and thermal overload. Also included are auto-on/off, silent turn-off with no audible transient, gold plated RCA inputs/outputs, and 5-way binding posts.

Features and Specifications: • Measured power output: 2 x 75 watts RMS (into 4 ohms @ less than 0.01% THD) • Signal-to-noise ratio: greater than 100 dB • Class A/B design topology • Input sensitivity: 1 V • Input impedance: 47k ohms • Auto-on sensitivity: 3 mV • Voltage requirement: 120/230 VAC, 60/50 Hz • Dimensions: 5.6" H x 5.7" W x 12.8" D.

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.5135 out of 5 by 148.
Rated 5 out of 5 by from Fine little amp for what it isThis is the second one I've purchased. I daisy chain them for speakers in different rooms. Having volume controls on each amp makes this a cinch. Don't be misled by the power rating. The manufacturer doesn't provide a stereo power rating for 8 ohm loads, only bridged mono into 8 ohms or stereo into 4 ohm loads - so caveat emptor.

Rated 5 out of 5 by from Versatile and dependableI'm looking for a new amp right now, and just decided I had to let everyone know about this one. I've had mine for a couple years, and it gets the job done! I've used it in all it's different capacities and it has done great with all of them.At first, I was using it for my pair of Dayton Classic 8" MTMs, but it wasn't quite enough to bring them to their full capacity. That was my first build. Then I made a smaller MTM pair for the Iron Driver competition in 2012 which this works very well for. I also built a big vented box for 4 Dayton DVC 8" subs wired in parallel-series-parallel for a 4 ohm load. This isn't rated to handle 4 ohms bridged, but I did it anyway, and it did well for those too, although obviously it didn't bring them to their max capacity either.THEN, I've added a 15" Bravox sub to my system, and so I have the big towers running on an iNuke1000, the small towers on a HT receiver, and the quad8DVC on one channel, and the 15" sub on the other channel of this amp. I have a splitter coming out of my mixer which sends stereo to the iNuke and stereo to this amp which is passing thru to the HT receiver. Using the built in LPF which works great. I know this is a crazy setup, but it actually has been working very well, although I'm running both towers full-range, which isn't ideal.The only two things I could dream of that would make this amp better were if it had more power (which doesn't matter for me anymore because I can use my mixer as a preamp, and this can drive both of these 4 ohm subs plenty) and if the auto-on didn't turn off when you're playing very low level music, or there's a quiet moment (which also doesn't matter for me because my whole system is always on and I just using my power strip for that.)All in all, for the price, this amp is good enough if it were just RCA in and speakers out. The extra features make it perfect for people who tend to use a variety of setups. It's built very well, looks nice, and has never given me a bad sound. It has the potential to put out much more power than rated, and has only even gotten hot when it's been running way over rated power for a long time. Still, after all I've put it thru, it's never failed me. I've blown a couple amps in the past to be honest. I tend to push them. This one is a survivor!My feedback on this amp is that it would be great to add a sub to your stereo setup if you have a high sensitivity sub, or don't listen at very high volumes. It would be great to have around in general for a stereo setup, or a backup, or testing amp. And from my experience, it can put out a really nice level if you use a preamp. Of course, if you blow it, you can't blame me. I'm just some guy. But I have bridged at four ohms and played heavy dance music for hours at much higher levels than it would put out without a preamp, and it didn't even flinch.

Rated 5 out of 5 by from Great amplifier.Over the last year, I've used this amp with a pair of bookshelf speakers, with a pair of tower speakers with built-in powered subwoofers, and in bridged mode with a center-channel speaker. It worked and sounded great for all of those scenarios. The auto on/off didn't work very well for me, so I just turn the power on and off manually. I like that the amp powers up and down without causing any annoying speaker sounds. After a year of regular use, the amp still works and sounds great. If I needed another amplifier, I wouldn't hesitate to buy another one of these.

Rated 5 out of 5 by from APA150 Power AmplifierWe have a holiday light display that features lights 'dancing' to musical sequences. In addition to broadcasting on a low power FM broadcast band transmitter, sound is provided for viewers who choose to leave their cars or who are checking out the lights in the neighborhood on foot.This is my third year of the display and previously (and the first few days this year) the outdoor sound was powered by an old Radio Shack amplifier the was probably about 45 years old and was rated at about 6 watts per channel.I decided I wanted to upgrade speakers and the power amplifier. In my searches for a power amplifier I found several of the newer digital amplifiers but noted the published reviews were mixed. Plus, I'm an old fashioned analog guy and actually have a few tubes in some of my musical equipment. When I read that the APA150 was class AB and had a 'real' transformer, I decided to make the purchase.I had a very pleasant experience on the phone with Parts Express and found I could get the unit rather quickly for a surcharge of less that $5. It arrived Friday afternoon in time to set it up for the weekend shows. The footprint closely matches the old amplifier I replaced and sits nicely on a window sill.I was very impressed by the heft of the amplifier and the overall appearance. And it sounds great. The combination of new speakers and amplifier are quite noticeable and I've received compliments from those who have viewed our display on foot. In fact some of them preferred the outside sound to their car radios!

Rated 3 out of 5 by from After about 2 years, unit cuts out oftenReally liked this unit, though the auto off never really worked well for me. I leave the auto switch to 'on.'Within the last few months, it has begun to turn off while I'm playing music. If I turn the music source off and on it works again. The unit also recently makes an odd cycling/clicking/scratching noise. Which I don't understand, because there ought to be no moving parts in there, right?Has been a pretty good unit, but should've lasted longer. I will be replacing it with something else.

Rated 5 out of 5 by from Very high value amplifierJust bought one to power my Polk OWM3 desktop loudspeakers.It is very well suited for that purpose because of the low noise when idling.I also have a SMSL SA-98e mini Tripath desktop amplifier and with this one i hear noise from the tweeters when no music is playing.No problem at 2meters or more away but at only arms lenght away from the pretty revealing Polks OWM3 speakers i can hear the noise and it kinda bothers me.I compared both amplifiers on my JBL Studio 580 loudspeakers and the sound was very similar but this was not the case on the Polk OWM3.Not only does the SMSL has the hissing noise from the tweeters but it also sounded harsh here.The Dayton APA-150 on the other hand is a sweet sounding and very detailed amplifier.No transformer noise or speaker pops when switched on or off either.btw the noise in the video was in the track,it's not generated by the amplifiers on test here.

Rated 5 out of 5 by from Worth the money spent so far.....Shipping was very fast (to a friend in NYC whom I was visiting for a week, the import duties are very high) and the unit came very well packaged. I'm not to sure about the complaints about auto-on sensitivity because I'm having no problems in that department. The power light is a little bright but definitely not a deal breaker, and remember the price! Like I said, well worth the money!

Rated 4 out of 5 by from Nice amp but...Bought this amp to power Infinity speakers connected to my TV and a cd player - yes I know only one out but I planned to build a switch box. Amp is nice sounding, like no sound but the auto on/off feature does not always work - I miss the first few seconds of music before it turns on, and if the CD is quiet, it never turns on. I stopped using that feature but it I would have like to use it.

Rated 5 out of 5 by from Excellent Amp - Ridiculously Low Price!I purchased my APA150 during the 2013 holiday season and have been enjoying it ever since. While it may not be as good as the best amplifiers I own (which are much more expensive) this integrated amplifier faithfully honors the music.That is to say that it adds nothing unpleasant to the music, and as such, errs by omission as opposed to commission.It is a nicely built, compact piece of hi-fi gear that has this audio enthusiast wondering why I have spent so much money on audio amplification in the past.When driven by the music software in my netbook computer, the APA150 easily drives my 1980's Linn Kan I bookshelf monitors to very loud levels. The APA150 is rated at 50 wpc into 8 ohms when used as a stereo integrated amplifier, which works quite well for powering any computer monitor or bookshelf speaker that I can think of.The APA150 is easily worth its $200 list price and was a bargain at the $125 price I purchased in at on during the 2013 holiday season.Highly recommended!

Rated 4 out of 5 by from Nice little amp for the price !This is a great little amp. I have it hooked up to my iMac and some Bose Acoustimass "cube" speakers with the Bose subwoofer and it sounds great. Plenty loud for this application, for me. Like many of the other owners though, I too am having problems with the "auto on/off" function. The amp keeps shutting off, so I boost the input volume and the amp comes back on but then shuts off again later on. I would have rated it 5 stars had it not been for this. Since I'm on my computer pretty much everyday, I just leave the amp on all the time now and it barely gets warm at the volumes I use. I've had it turned on and running now for about 2 months. I might try hooking up this setup to my TV next and see how that performs. Very happy so far with the sound of this amp and the quality of construction for the price.

Rated 4 out of 5 by from Very good for the moneyI purchased this amp so that I could use my existing rear-channel amp (Parasound 275) bridged in mono to get more power to my center channel. For the price, this amp is hard to fault. Bear in mind, however, that the 2 x 75 watt rating is for a 4 ohm load. I was using the Parasound to run the rear channels before. The Parasound is rated at 2 x 75 w @ 8 ohms and 120 w @ 4 ohms...a huge difference.My rears are Energy RC 10s, rated at 91 db, so I figured the Dayton amp would be plenty. I was has just enough power to get the job done, and no more. For music listening, I keep the amp's volume (gain) control at the 12 o' clock position, and for music I turn it all the way to the right. It has about 1/2 the power and volume of the Parasounds, as the ratings would suggest. Please don't think I'm being critical here...the Parasound is nearly four times the price, and has higher current reserves.Sound-wise, I was missing a lot of detail I had previously enjoyed. I switched out my Signal Cable Analog Twos for a pair of Signal Cable Resolution Reference (silver) cables, and the clarity, detail, and punch of the Dayton Amp came alive...very close to the Parasound. I would prefer more power; say, double. But still this is a lot of amp for the money. It is well built, and looks like a much more expensive amp.A couple of quibbles, however: When I first opened the box, the amp had a distinct "burnt" smell, almost like an electrical odor (which, of course, would definitely not be the case, as it had not been plugged in). The smell is almost completely gone now, and I would guess it is related to a plastic or glue of some kind. The other quibble is the blue light, which is distractingly bright, particularly when the amp sits high on a component rack, as in my configuration. I solved that problem by taking two self-adhesive round felt pads and poked a sharp hole in the middle of them with an awl. I then stuck the pads together and put them over the light, and, "voila"--the distracting blue light became a muted "dot" instead. If you don't need a lot of power reserves, this amp will serve you well. It is one of the best values I have encountered in hi-fi.

Rated 5 out of 5 by from Parts Express and Dayton Audio Top the List!Recently purchased class T Dayton Audio power amp. The item is better than many regular transistor units I have used. Small, lightweight, good output and heat dissipation. Completely quiet. Parts Express was very quick and professional in selling me the item. I have recommended Parts Express and class T to several other people.

Rated 5 out of 5 by from Better then expectedHere is the trick with this amp. When you first get it turn off the auto on feature, plug it in, turn it on and leave it for 24 hours. Then listen to it. It makes a huge difference. The sound becomes, smooth, warmer with great bloom in the mid-range. It takes a good 24 hours to settle in and warm up. I usually don't turn off my solid state amps and pre-amps. So, I leave this amp on all the time as well. It stays cool so heat is not a concern.Changed out an Acoustat amp for this one and was pleasantly surprised. I am looking to get a second one and bridge it to run as mono blocks.

Rated 5 out of 5 by from Clean Power and Runs Quieti bought this powered amplifier to use with non-audiofile speakers cerwin vega at-8's which had broken foam surrounds so i replaced the surrounds from a kit here at parts express. speakers are rated 100w@4ohm92 or so. i thought 75rms would be plenty of power for these speakers. can get very loud and stay very clean at high levels.PRO: great power output, high level inputs, low level inputs with outputs, can be used as IMO a low powered subwoofer in stereo 4ohms or bridged 8ohms, simple face plate, non-click volume dial also smooth and tight, size is very efficient, weight does not matter because its not a weight lifting object.CON: no low level outputs for running full range speakers in stereo and have a powered subwoofer running output, power light on is bright blue and no dimmer switch, low pass filter only can go down to 50hz a bit lower would have been nice if you were to use as dedicated subwoofer amplifier, no remote control function.this power amplifier is one of new favorite power amplifiers but would still like to see something this small and produce the amout of power as my kenwood basic m2's and m2a's 220rms@8ohms%0.004thdi love the amplifier thank you dayton audio and thank you parts express

Rated 5 out of 5 by from A far better budget choice than Tripath IMOWhile from a hype perspective, Class D/T/proprietary what have you 'it's another PWM amplifier' may be the new Class A, to my ears, having tested just about every entry-level amp that I can get my penny-pinching audiophile hands on, this is definitely the one to get. The dynamics, power, speed and accuracy (especially in the low end) you're going to get out of a well built A/B amp will handily best anything you're likely to hear out of a comparably priced Tripath amp, and this is easily the best built amplifier I've seen or heard at this price point. If you look at the distortion numbers in the power band, they're well below anything you're going to hear anyways, and 75 watts a side is really a sweet-spot number for most speaker applications. The fact that you can bridge it and use it as a subwoofer amp (which I have done as well) is just gravy, and for most sane home theater applications, 150 watts is going to do you just fine. I probably have half a dozen of these beauts performing various duties around my studio and home theater, and I really couldn't be more pleased. In a perfect world, I would love to see a 4 ohm stable monoblock version of this sans the volume pot someday; if the price stayed the same, I'd dare go so far as to say that might be the perfect budget amp. Exactly as they are though, these amps are fantastic.

Rated 5 out of 5 by from Dayton Audio APA150 150W Power AmplifierI have been dealing with "partsexpress" for quite a few years now and never had a negative experience with their products. For the last few years I have been building my "Man Theater" and I am finally completeing it with this amp.I moved to Orlando, Florida in 2007 and bought a home with a "Florida Room" and after weighing the "pro's & con's" I decided to close in that room and make it into a "Home Theater Room". I hired a contractor and had it changed into part of my home. Tore everything down and had new walls and roofline built and the finished room was 22'x22'x9' a really nice size room for my audio & video needs. Over the years I have been buying all new equipment to fill that room and right now I have a 60" plasma T.V. with a 1000watt Yamaha amp with a 9.1 speaker system which includes my sweet "Dayton Audio T1503K 1Mk III5 Titanic 1000 Watt Subwoofer". It gave me pleanty of bass but I really wanted to feel it and not just hear it, so I decided to purchase 2 "Clark Synthesis TST239 Silver Tactile Transducer Bass Shaker" and mounted both of them under my leather recliner sofa. After relizing that I couldn't hook them up to my "Mk III5" Titanic 1000 Watt Subwoofer" I wrote an e-mail to "partsexpress" and asked what would be my best option for an amp that would be very good for those transducers without over kill. The following day I received a reply back from them saying my best bet would be the "Dayton Audio APA150 150W Power Amplifier". I ordered it and it just arrived today and I have to say just by the weight of it "almost 14lbs." told me that they don't just use an "output power transistor" they use a "power transformer with a cooling fan" quality?, I think so! and at a price that can't be beat.As I said I have been dealing with "partsexpress" for quite a few years and I'll tell you these people deal with what equipment you have and match the products they sell to what would fit best for the type of system you own. Their not like alot of other companies that try to sell you the best they have in order to make a bigger sale. So, what I have to say to you guy's at "partsexpress, thumbs up" this is one of the reasons why I have been a faithful customer of yours for the last 10+ years and looking forward to another decade of your fine products and prices.I will be back after I hook-up the "Dayton Audio APA150 150W Power Amplifier" to my transducers and let you guy's know how it is, "I'm sure it will be favoritable" until then, everyone enjoy.Pete C.

Rated 5 out of 5 by from Perfect!I was looking for a small sized amp with ample power for my music room. It had to be powerful enough to hear jam tracks or other music with electric guitars, basses, and a drummer.I'm using Sony SS-B3000 speakers with it in mono to keep everything at the rated 8 ohms. The Sony's are 8 ohms.Others have mentioned the unit not getting enough drive with an iPod or other device using headphone jacks to supply the amp's input source. I haven't had a single problem with that or anything else. The volume/gain control is smooth and useful from 0 to 100%.It just works and works well and has no problem keeping up with up during our practice sessions.I would buy another one in a heartbeat!

Rated 5 out of 5 by from Nice clean amplifierI bought this amplifier as a low cost alternative to more expensive type AB amps. I use it mainly for music in a very small apartment. If you want a audiofile setup in a bedroom or den, this is not a bad choice. It features a low pass adjustable frequency cross over for use as a sub-woofer amp only or can be used as a "flat" main amplifier, a stereo/mono switch and an auto-on either/or feature. It takes a number of seconds before it turns on when it detects the source, though... so, if you pause the source and come back to play it, it doesn't go back on right away. There is no headphone jack, so you will need to set up a headphone amplifier if your source doesn't have one. It has only one set of inputs #I have a source selector# and one set of outputs which allows you to use a headphone amp even when it is off so you don't have to leave the amp on all the time. What you see is what you get in the front... no frequency adjustments. But, the amp is so clean sounding I personally don't need the adjustments. Works well with 8 ohm speakers and I found the device loud enough for my little living room. 2 inch clearence is recommended on the top and the unit is quite deep. So, if you are interested in a basic audiofile amplifier with only a volume knob for a small room, I would recommend it.

Rated 2 out of 5 by from Volume Control Static & Cutout After ~1.5 YearsI have been using this amp with my computer with considerable performance satisfaction up until recenlty. The volume control became staticy and each channel cuts in and out when the dial is moved, like isn't fully making contact. I checked all of the connections, but the static and cut outs occur when moving the dial, retaining the lower amplification or full cut out in some positions.I've had to dial the best full and balanced channel position and then use the computer volume. It's past the warranty and not worth sending back, but a such a waste to purchase to new equipment for a volume control.

Rated 4 out of 5 by from Frustrating for iPadThis is a clean amp with a flat response, but I find myself really missing tone controls since my main use is to amplify iPad music.First of all, it cannot amplify the headphone signal because it's too low, so I had to get an adapter to use the iPad line out signals.Next I discovered that when plugged in its charger, the iPad line out signals have a noticeable amount of digital noise. It's clean when running off of battery.Finally, I discovered that many music sources for iPad, e.g. Pandora radio, etc..., do NOT have any equalizer controls, so I find that with my AR speakers the bass response is really weak.Most of these complaints are iOS and the iPad's fault, but I feel I could compensate if this amp had tone controls.

Rated 5 out of 5 by from Surprisingly goodI bought this amp as a temporary solution for a subwoofer and to generally horse around with. Long story short, it's ended up in my main two channel listening set up. It doesn't have the monster power my bigger amp has, but it sure is doing a whale of a job considering the price. I'm listening to it right now, driving a pair of AR3s, not the easiest load ever.My observations: It's adequate as a subwoofer amp, and probably just fine on a lower powered system. It does the job, but if trying to integrate into a system with a more powerful amp driving the main speakers, it's very difficult to get set up. As a main amp for a two channel system, however (and I assume as a sub amp on a lower powered system) it delivers much more performance than you might expect. I can push these AR3s to moderately loud levels in a smallish living room and this amp doesn't seem to be straining at all. I'm pretty impressed. I'm so happy with it that it has taken up residence in this system, relieving my Denon POA 2400 to drive my AR9s downstairs. Honestly, I don't miss the Denon at all in this set up, and that's saying a good bit.Some nice things - if you need a two channel amp with subwoofer crossover, this is a great solution. I have a sub with two 10" drivers and this let me drive the 4 ohm drivers on separate channels. The auto on feature is working great for me too. Saves one more switch when turning the system on.My only wish is for a "B" speaker output. On the whole, kind of a nit-pick given how well this amp is working out.

Rated 5 out of 5 by from Simplicity at it's bestI have it hooked it up to my PC with the ASUS Xonar STX and Yamaha NS-30X speakers. Sounds phenomenal. I have no real complaints about it at all.Never get's hot at the volumes I use it, just slightly warm.I read a few review about the auto shut off feature being a problem. Me personally, I haven't run into that unless i'm playing music really quiet, 'really' quiet.The ability to branch/stack amps from this one is a nice touch. I haven't used it yet but i'm sure I will eventually.I really like the fact that it's so simple. There's no equalizer adjustments, no real bells and whistles. Just a plain amp that works and boy does it!

I am running 4 pair of "house" speakers and it seems to be as clean as the Technics receiver it replaced.Auto Power on/ is a off nice feature.Other thoughts - Sherwood has since improved the specs on their RX-4105 to .008% THD (supposedly) That would add a tuner/ slector to mix for a few bucks less.

Rated 5 out of 5 by from Great for TV sound systems or home theater.Needed a 2 channel power amp with auto-on and RCA loop thru to run a 2.1 system. Works perfectly, but will shut off if you leave the volume too low for a few minutes...but it's supposed to do that. Runs a little warmer than anticipated (running 8 ohm loads), but I don't think the fan has come on yet, or if it has, I haven't heard it. I run the RCA loop thru to my powered sub. I put a small piece of electrical tape over the blinding blue power led on the front. Looks to be the same as the Jamo MPA201 which is 2X the price. Good deal from PE when on sale.

Dayton Audio APA150 150W Power Amplifier

I am running a 2.1 system for a computer with an integrated sound card, Because there is not a pass through for a sub, is there a possibility that the sub and the speakers will be off? I mean off in a sense when they give sound, it is a powered sub.

Hello Parts x, I bought this amp along with two bass shakers.  Do you have a recommended connection diagram?  I can place a splitter on my LFE out but where should it go on the amp. Also, i read that it is best to hook up two bass shakers in parallel ?

i have a tv with  bose speakers surround sound and was wondering if this would work to power the speakers, i have no room for a big clumsy receiver,just want something small

Asked by: rooster479
This amplifier is only designed to provide power to two speakers (a stereo left/right pair); it cannot provide surround sound.

For some time I've had these connected to the PC speaker jacks.  However, the 3mV trigger is not effective at turning then on.  Any suggestions to increase pc speaker voltage output?  Will a stereo distribution amplifier help?  I need auto off too.

Asked by: greyleopard66
I use one of these amps at my desk, connected to my PC. I often turn down the volume setting on the amplifier, then turn up the PC sound card's output, and I'm able to get much more output than I need this way. This also gives me more fine control over the output level using the PC's volume slider within Windows. I would recommend a similar arrangement for you.

I have recently put in a 5.1 surround sound system in my basement.  I have one passive 12" 400W peak power sub.  Would this amp be a great choice in powering that sub?  Thank you.

Asked by: Lambo23
Yes, as long as the sub is no less than 4 ohms for stereo mode (perhaps a dual voice coil woofer) or no less than 8 ohms in bridged mode.

I purchased this amp 4 years ago.  Worked fine until last week when it started to produce a clicking sound in the amp (not the speaker).  Turned off, then turned back on.  Clicking gone, but amp not producing power (even though it is on).  Help please.

can this amp drive a pair of power hungry 4ohm speakers ?

Asked by: Rich01
Yes this will work with any standard 4 ohm speaker as long as it is in stereo mode. Power hungry usually means inefficient. This will limit the output capabilities depending on the actual speaker sensitivity, but the amp will have no problem driving that load.

Driving two Bass Shaker AST-2B-4...better to connect in stereo or mono bridged?  If mono bridged connect the Bass Shaker's in a series?  Would bridged be too much for the AST-2B-4?

Asked by: rsnow
You will get the same output power into each bass shaker with both configurations. I generally recommend wiring one on each channel using this amplifier, but it will not matter either way.

How would you hook this up to a standard PC, 3.5mm audio for true stereo input and output to this amp?  3.5mm stereo to mono splitter then two mono to stereo rca cables one for left and one for right? Sorry newb question. :)

Asked by: rsnow
All you will need for this is a standard 3.5mm to RCA cable which you can see below.

I just bought the Apa 150 amp.  I have four aura bass shakers.  How should I wire these ? What settings should I use in the back ??

I am looking at purchasing an amp to power 1 Clark Synthesis TST209. Eventually buy a 2nd one for same couch (unless single is adequate). How would I set up powering the transducer & not have it overpowered by the amp? Is this amp sufficient for 2 Clarks?

Asked by: krispjorn
The best way to wire one or two of the Clarks to this amp is simply to wire one to each channel of the amplifier for the full 75 watts of output power.

I have 3 home theater chairs that have aura bass shakers on them. They are 4 ohms each. Would it be ok to run these 3 in series at 12ohms with this amp? Would I use it in bridged mode?

Yes you can power three of these wired in series, I would recommend bridging the amplifier.

Would you recommend to use one amp or two in bridged mode for Wharfadela Obsidion 600 front speakers. Will it be stable in bridge mode even if the Wharfadale's are 6 ohm speakers? The spec says that the bridged speakers should be minimum 8 ohm ones.

Asked by: Bela
I would not recommend running this amplifier in bridged mode with a 6 ohm load.

Can it drive the 6 ohms (200W) Wharfadale Obsidian 600 floor-standing front speakers with this amp(s) from a YuLong SABRE DA8 DSD DAC and get better sound then going through the Denon AVR-X2000 line ins from the same DAC?

Asked by: Bela
I cannot tell you if it will specifically be a better sound but it will not have a problem driving them.
