Can I use one apa150a to safely run multiple speakers that are pre-wired in my house that have impedence matched volume controls?
I need to power 3 sets of speakers that are pre-wired in my house. They are in the ceiling of my dining room, in the family room, and one day I plan to hook up speakers outside where there are wires already outside my house. All 6 speaker wires come together in the basement as two channels comeing out of the wall. Each room listed above has its own impedence matched volume control. I want to be able to have music playing or audio from the tv throughout all 3 locations that is loud enough to hear over fairly loud conversation. I don't want to shake down the house, I just want it loud enough for people to hear even if there is conversation going on during a party and also if people are about 100ft away outside.
Yes, The impedance matching volume controls will prevent a low impedance condition from causing any trouble for the amplifier. It should work with no trouble.

Can this drive 4 ohm speakers in bridged-mono mode?
Can this be used in the bridged mode to drive low impedance (4 ohm) speakers?
It is not recommended, a 4 ohm mono load will present itself as a 2 ohm load to each channel. think of it as each channel driving half the load. It "might" run it, but it won't like it for very long.

Is there a way to adjust auto on sensitivity?
Many have complained about auto-on sensitivity of the APA-150 being too low and time before auto shut off being short. Is there any way to adjust these parameters?
No, the auto-on sensitivity is approximately 3mV, and it is not adjustable in any way.

Line Input(s) for Mono (Bridge) Mode?
I found the online manual here: http://www.daytonaudio.com/index.php/audio-video/audio-amplifiers/apa150-150w-power-amplifier.html but it is not clear whether when using mono/bridge mode the two line inputs are combined for amp output or only one input is used? One could assume Left and Right inputs are combined, since there is nothing to indicate otherwise, such as one input labeled "mono".Thank you.
Yes, in bridge mode, the left and right inputs would be summed to a mono signal.

How would i connect the DV62SI speakers to this amp, they are 8ohm speakers, and how much power would they be getting, i dont know whether to get this or the dta-100a for them
You would set the switches to flat and stereo and hook it up as you would with any other amp.This will most likely push around the same power at 8 ohms as the dta-100a around 35-40 clean watts a channel, but this amp is stable to 4 ohms which I view as a big plus over the dta-100a.If all you are going to be using are 8 ohms speakers then I would go for the dta-100a as you are paying almost $40 more for features you would not use in this amp.

use with Onkyo receiver to bi-amp?
How would I go about setting a mono block amplifier up so that I could bi-amp my warfdale speakers that I'm currently running off of my onkyo 7.1 receiver/amplifier? Or is it possible to do so? How would the crossover switch come into play?
If your onkyo recevier has pre amp outs then you would hook this amp up to the front L/R pre amp outputs.There are a few ways to do this and I don't know from you question if you wanted to use a combination of your onkyo and a APA150 to bi-amp or multiple APA150's? Or how many speakers you wanted to bi-amp, so I will give examples for just your front L/R.#1: Bi-amp using Onkyo as one set of outputs either bass or mid/high and a single APA150 in stereo for the other set.#2: Bi-amp using Onkyo as a set and two APA150's in bridged mono for other.#3: Bi-amp using two APA150's in stereo, one for bass and one for mids/highs. Here you could choose if you wanted one amp per channel doing both your mids/highs and bass or one amp doing both L/R bass and one amp doing both L/R mids/highs.#4: Bi-amp using four APA150's in bridged mono, two per channel one for mid/high one for bass.Ignore the crossover setting on this amp it is for subwoofer use, just set it to fullrange stereo or mono depending on which way you wanted hook them up.

Using a Preamp with AMPs and Subs
I currently have two APA-150s in bridged-mono mode powering a pair of speakers. Would I be able to use the line level outputs from each APA-150 to send a signal to a pair of subwoofers? Since I have a preamp, I am thinking I could use the volume knobs on the APA-150s and the subwoofers to match their levels and use the preamp to adjust the system's overall volume. In this case, the line level output from the preamp would increase in proportion to the APA-150’s line level output, right? Also, when using the line level outputs in bridged-mono mode, which output (L, R, or both) should I use?When using a preamp to control the overall volume of the system, should I turn the volume knob on the APA-150 all of the way up (to the right) and solely use the volume control on the preamp?I heard a vague rumor that a preamp can add too much gain to a signal and somehow harm the line level inputs on the APA-150; is this true?
You could easily use the line outputs from the APA-150's to send to the subs. The outputs will send the exact same signal as the input, it is in a sense an internal y-cable. So use the same channel output as you are currently using as your input.The preamp for volume control will work fine, do as you said match the volume of your subs with the APA-150's.The volume on the APA-150 should be as high as you can get it while matching the level with your subs, having the volume knob on the APA-150 turned down will require more signal voltage from the preamp in order to play as loud, that is what will cause the problems from the inputs being overdriven.

Can I connect a powered subwoofer to this amplifier?
If the powered subwoofer has high level inputs then yes you can and it will work just fine.If it only has line level inputs you could connect it to the line outputs on this amp however they are not controlled by the volume knob on the amp.

What country is this amplifier made in?
The design and engineering are all USA and the assembly or sub assembly may be USA or from a foreign manufacturer to Dayton Audio specifications. It important to understand that nearly everything audio is either all or in part manufactured by a foreign facility.Even companies such as Mc Intosh uses some foreign manufacturers for componants in their line.

How would I use this amplifier with a powered sub (Dayton Audio SA70 ) and 4ohm satellite speakers?
Hi,I want to repair a broken Klispch 4.1 computer speaker system. I pulled the old amp from the sub, and replaced it with a Dayton Audio SA70 sub woofer amp. However, it appears that it cannot drive the 4ohm speakers. If I were to purchase the APA150, would it work with the 4ohm speakers, and how would I wire everything up?
Your SA 70 only powers the subwoofer. The output of the APA 150 would go into the plate amp "from amplifier". Then you would connect "To Speakers" to your satellite speakers. Just wire "+ to +" and "- to -" all the way around and you'll be fine - don't be concerned about the 4 ohm load.

Can the APA150 run a sub while also in bridged mono mode?
What I am planning to do is get 2 of these in mono mode so 150w and 8 ohms to each speaker. What I want to know is while doing this can it also handle a powered subwoofer. Seeing as one APA150 must be connected from the line output into the other APA150 line input I assume it would be possible to use the free line output on the second APA150 with a powered sub and not mess with the mono setup? Any help with this would be appreciated. Thanks in advance.
The correct method of connection would be one APA150 in stereo mode to run your Left and Right speakers. Use the other APA150 in mono to run your sub. It has the crossover controls you need to roll off the highs from the sub. Use the left input in mono mode. Here's the issue - if you took the audio out from the stereo APA150 and used a "Y" cable to sum the input on the mono APA150, it would degrade the stereo signal to the main amp. It would be best to use the LR from your source and it's LFE output for the sub. The other option would be to use the second APA150 in stereo if you have two drivers in your subwoofer, or a woofer with two voice coils. There are also stereo to mono signal combiners (passive) that you can purchase so you can use the second APA150 in mono. You would need to research that.

Volume and fan?
I just got one of these. I never had an amp with a volume control. Should I set the volume at maximum on the amp and let my preamp control the volume. Or would it be better to set the amp at less than maximum? Also I see the fan is not running. Is this normal? The amp barley gets warm so I guess the fan only comes on when needed. Is that correct? Also when I switch to my computer with the pre amp I get a low barely noticeable hum I don't hear from the other inputs. Any ideas on how to fix this. I tried a 2 prong on the amp power cord and there was no change.
You never want to set the volume to maximum on an amplifier. I would turn the volume on the preamp to a level that is comfortable, keeping the volume on the APA150 around 12 o-clock or so. You can adjust this as needed. The fan only comes on when needed so this is not a problem. It sounds like you have some noise coming from the computer, I would recommend trying a ground lift adapter in line with the 3.5mm cable.

What's the difference between this amp's Low Pass Freq. and a Subwoofer's crossover control?
Are those two the same? This is the only mini amp I've encountered that has a Low Pass Freq control. I'm confused as to when I would use this over a sub's crossover control, like say this one at the back of the sub: http://www.parts-express.com/images/products/hires/300-627_hii.jpg
The controlled speaker crossover receives the audio after it had been amplified. This means the componants must be heavier built and are a little less accurate in control.The switchable crossover in the amp is typically between the pre and power .amps. It is very low power at this point and cost efficient to build a better control device. Typically a crossover within an amp or one that deals with line level is called active and one in a speaker is called passive. I use active whenever I can.I

What is the input sensitivity of the APA150 amp?
This Dayton Audio APA150 power amp is designed to work with standard pre amp / mixer outputs. These range somewhat but actually minimal. The low is around .75 volts and the high around 1.5 volts. The range will provide rated output.

Tucking the monoblock into a pre/power combo
I am using stereo pre and power amps and would like to add an 8ohm passive sub using the APA150. Can I, set to mono (bridged), input both L+R RCAs from the pre amp and output L+R RCAs to my current power amp whilst retaining stereo signal?
This amplifier should work fine in that setup.

I am in the process of matching home stereo components but in this economy price is paramount. A Mono Block set up is what I'd like to do,.
If I wanted to use 2 Dayton Audio APA150 150W Power Amplifiers with a Pre Amp for central control, which make/model would you suggest? I also have 2 KEF C200SW's that have never been used but would like to for a home cinema system. For that purpose would 1 Dayton Audio APA150 150W Power Amplifier be good enough to drive both? They are individually rated 250W @ 4 ohms.
This amplifier would be suitable to drive any 8 ohm speaker when run in bridged mono mode. Unfortunately we do not currently carry a preamp that would be suitable for this application.

Would this amp be a good choice to power 2 BIC America RTR-EV15 floorstanding loudspeakers?
Or should I look into a different amp? I think they have a 95db sensitivity and a 225 watt rms.
This amp would drive those speakers without issue. Whether it will provide enough output for you specifically is impossible to say.

Can I run two main speakers AND a powered sub ?
I want to run 2 book shelves and a powered sub - can I run the speakers AND the line out to the sub at the same time ??I am running an IPOD for music when tailgating
Yes you can. The line outputs are a parallel of the inputs and will send the full signal to your sub. Make sure your sub has a built in crossover, otherwise it will attemp to play the entire audio signal. Enjoy!

If I want to connect two of this (one per channel in a Stereo configuration). How I should connect it into the pre-amp ?? I Have a Gemini PA 7000 pre-amp.Thanks!
You would connect the left and right outputs from your preamplifier to the left inputs on each of the APA150s. Set the Stereo/Mono switch to Mono. Wire each speaker in bridged-mono configuration at the amplifier (Left + and Right -).

Will this amplifier work with 4 ohm speakers in mono mode
I know if say 8 ohms in bridged mode but will it hold up ok at 4 ohms ? I don't care about the warranty I just want to know if it built heavy enough to handle it ? the amp I have no says the same thing about 4 ohms but I have also been running it for about 3 years in 4 ohms without any problems and I drive it hard sometimes, Early SAE amps which mine is , 30 years old say 8 ohms but the maker knows it will do 4 ohms. I wont be driving these hard but I will be driving Magnepan speakers with them. So I am looking for an honest answer from a tech guy who knows how well and how overbuilt an amp is if he knows whats in it ! so ignoring the warranty would you give it a try on your 4 ohm speakers if you owned a pair of these? Thanks Larry
This amplifier is rated to deliver 75WPC into a 4 ohm load in stereo mode. The Mono setting is for bridge mode only, and it is not rated to handle a 4 ohm load in that mode. While it may be capable of operating under stress for some time, we cannot state that it will tolerate a 4 ohm load in bridge mode. If it were stable at 4 ohms bridged, we would state that fact, and the warranty would include coverage for that kind of operation. As it stands, it is not rated to be stable at 4 ohms bridged, and operating the device in such a manner would, indeed, void the warranty.

LIne Level Outputs
Are the line level pass-though outputs affected by the gain control, low pass filter, or if the unit is powered off? What is the input voltage required for full rated amplifier output?Thank you.
The line level pass-throughs are not affected by any setting, and work even when the amp is unplugged. As for the second question, I do not know.
