AudioSource AMP100 2-Ch Source Switching Power Amplifier
AudioSource AMP100 2-Ch Source Switching Power Amplifier is rated 4.3803 out of 5 by 71.
Rated 3 out of 5 by from A Mixed BagI purchased the AudioSource Amp for my secondary 2-channel system. It is vintage with DCM Time Frame 600 speakers, an Advent 300 (used as a preamp) and a terrific Rotel multi-disc CD. The additional power was noticeable and the general build quality was excellent, for the price. Sonically, the AudioSource's bass was not as well defined, being a bit boomy at times. The highs exhibited more solid state sharpness than I prefer with these speakers. Functionally, the only negative is the speaker binding posts. I use custom-made very heavy gauge bare wire tinned with silver solder. When I opened the binding posts all the way it was quite impossible to close them: they seemed locked in place. I was forced to use needle nose pliers to unlock them and then I could tighten them down by hand.If you are purchasing this unit for a more modern system, and plan to use banana plugs for the speaker connection, then I think this would be a fine purchase, especially for the price. I am, however, returning mine to Parts Express.

Rated 4 out of 5 by from Very good 2-Ch Amp for the MoneyFolks, for the money and basic features. this amp is very hard to beat, unless you build your own. Buy it. It works as advertised.

Rated 4 out of 5 by from Audio Source Amp-100I bought this amplifier to power my aura pro bass shaker transducers and so far, they work great together.

Rated 5 out of 5 by from Great no nonsense ampNot a very powerful amp, but great clean sound, high quality construction (in particular the quality of the case and rotary knobs are surprisingly good), and all the right features for a simple amp. Even when paired up with my fancy NHT speakers the sound of this amp was impressive.

Rated 4 out of 5 by from AudioSource AMP100This 2 channel amp is a good performer considering it's modest price. It has been around for a while-I own more than one and have not had any issues. They run fairly cool. You can't engage speakers A and B simultaneously but the output of this amp doesn't warrant that anyhow. One curious thing about the dual banana jack speaker outputs-the left channel is on the right side of the row & the right is on the left--just mentioning it. This is not a high power amp, but it is a good value nontheless--pick up one or two while they are still available.

Rated 4 out of 5 by from Not all things to all people, but good enoughOther reviewers have covered some of the operational aspects of this, so I won't cover those topics again. Let me fill in a couple of non-obvious gaps instead: 1) All inputs, all outputs, and the chassis share a common ground. Not that this is bad, but floating single-ended inputs can be helpful in some situations. They're not to be had here. Fortunately, the chassis is well-isolated from the power line. 2) Idle power consumption is about 12W at .6 PF. Typical for a transformer-diode-capacitor power input topology. If you have a lot of these on one power line, you may need to worry about the lousy power factor. 3) Clipping recovery is a thing of beauty, even at 10KHz. There is absolutely 0 misbehavior or artifacting coming out of clipping and it is perfectly symmetrical. MANY "high quality" amplifiers do not behave this well. 4) frequency response easily complies with the specified 20-20,000Hz spec. It holds out well to around 15Hz and then falls off, similarly at about 30KHz. No problem here at all. 4) I found a very strange behavior with a square input. It works properly with square waves up to about 200Hz, but somewhere above that, a square wave input causes it to shut down. Remove the square wave and it immediately turns back on. Now sine waves, even up to 100KHz do not present a similar behavior. I regard this as very unusual and, frankly, difficult to explain. I've never seen anything like it. It shouldn't affect normal use of the amp however, as I was looking for transient response, which seemed appropriate where I was able to test it.I did not test short circuit tolerance. You probably shouldn't either.Overall, the amp gives a good, well-built impression. It's solid feeling with good feel of controls. Binding posts aren't the high-$ premium types, but they are adequate. I recommend banana plugs rather than attempting to attach wires directly because they are so close together.With 8-ohm resistive loads, it generated minimal heat. It produced no stray noises at any time, either in the speakers or physically from the amp itself. I would have preferred a detachable line cord.Overall, nicely done and a good value, as long as you appreciate the compromises made to reach this price point.

Does the product documentation indicate that this amp can drive a single pair of 4 ohm speakers?

I can't tell from looking at the back of the unit.
Asked by: michaelgp
Specifications: • Output power 50 watts RMS per channel @ 8 ohms, 60 watts RMS per channel into 4 ohms" The unit delivers 60 watts per channel into 4 ohms. The terminals are labeled 8 ohms so that when two pairs are connected the impedance doesn't drop below 4 ohms - so you are okay to use a single pair of 4 ohm speakers with this amp

can an equalizer and turntable be hooked up to this?

Asked by: ryancarleton
Yes they can, however it would be a good Idea to get an ART DJ PRE II Phono Preamp with RIAA Equalization for your turntable.

Can this amp handle a 4-ohm load if it's bridged

I have this amp and like it a lot. I'm thinking of running it in the bridged mode this winter to play Christmas carols through two 8-ohm speakers outside. Will it handle a 4-ohm load if it's bridged?
Asked by: Chayla
Here's another way of saying what the last guy said: If a 2-channel amp is not spec.'d for a 2 Ohm load on each channel, then it is not spec.'d to drive a 4 Ohm load when bridged, When bridged, each channel will "see" a 2 Ohm load. It's not always a matter of handling the extra current, either.

Is this suitable for 230VAC/50Hz mains?

Asked by: marinoss
Nope sorry 120VAC/60hz only.The Dayton DTA-100a and the APA150 are if you are looking for alternatives.

Are there any issues with running two sets of speakers at once?

I'm thinking about using this amp to run two sets of outdoor speakers, will running in A+B mode the majority of the time be asking too much?
Asked by: Eyota
This amplifier is 4-ohm stable, so as long as you are connecting two pairs of 8-ohm speakers you will not have a problem.

good enough for multi-room?

I have a home with 4 pairs of speakers in different rooms (kitchen, bedroom, living room, and outdoors). They all have volume controls but the controls are not impedance matching. Would this amp be able to run a single stereo to all my speakers reliably if I install an impedance matching speaker selector? I won't be running things especially loud the music is just for background. I've looked at more expensive options (Russound x125) but wonder if that may be overkill... also considered installing impedance matching volume controls but those are minimum $20 x 4, which seems like it could be better spent on a capable amp or an impedance protection selector.
Asked by: troy2000
Yes this will work fine for that application as long as you have the impedance matching selector.
