A favorite of audiophiles everywhere, the AudioSource Amp 100 two-channel power amplifier is built to deliver powerful music, pure and simple, with few extra controls to get in the way. Listeners can use the Amp 100 as an independent stereo amp (50 watts x 2 into 8 ohms) when used with a preamp, as a second zone amplifier in multi-room applications, or as a rear-channel amplifier in a 6.1- and 7.1-channel system. Combine the Amp 100 with an additional monoblock amp (the Amp 100 delivers 150 watts RMS of bridged power) and a preamp and listeners can independently drive two front left/right speakers or two rear speakers, further clarifying each channel to create dynamic, high-end sound. To connect additional components to the amp, use the included stereo inputs with automatic priority override (for connecting to a source such as a receiver, CD player, or preamplifier) or the auxiliary output for creating a multi-amp setup.
The amp boasts a precise frequency response of 20 Hz to 20 kHz and total harmonic distortion of 0.02 percent. Additional features include A, B, or A+B speaker selector switches, front-panel mounted volume and balance knobs, and five-way binding posts that work with both bare wire and banana plugs. Plus, at 16.5 by 2.9 by 9.25 inches (W x H x D), the device should fit comfortably in most rack mount or home entertainment setups. All AudioSource amps are backed by a two-year warranty on parts and labor.

AudioSource AMP-100 2-Channel Bridgeable Stereo Power Amplifier Reviews
Onkyo is dead to me and Audiosource has a new and happy customer. My choices narrowed down to an Onkyo M-282 or the Audiosource Amp 100. The Onkyo was $200 and the Audiosource was about $90 at the time. They got here in 4 days and I took one out and inserted in into the system. The Onkyo put out 100 watts per channel and the Audiosource did 50 watts at 8 ohms. Nod goes to the Onkyo because it just had to be better at the price difference.
I had already installed impedance matching volume controls so I was not overly concerned about the amp getting dragged down with a 2 ohm or similar load. The sound is very impressive. It is now playing all 16 speakers at a level of sound volume and quality that is way beyond what the Onkyo did at 3X the price. There is no need to use both amps in mono mode. A couple of years ago I was looking for a stereo amp to power 8 sets of ceiling speakers in my home.
I only wish I had taken the chance before blowing good $$$ on the Onkyo M-282. Since the Onkyo was now a doorstop, I decided to try the Audiosource 100 and since they were 50 watts at 8 ohms or 160 watts bridged, I bought two from Amazon. Nod to the Onkyo. We will come back to this point. After way too much time on the phone at Onkyo Customer support, it became clear to me that there was no repair route that would be less than the cost of a new Onkyo; the culprit was the "Amplifier Portection Circuit".
Last week, after just over 2 years, the Onkyo rolled over and quit. Did I mention that I set one of the amps up in 50 watt stereo mode. The Onkyo had an Amplfier Protection Circuit and the Audiosource had a fuse.
I wish the A/B switch would turn on both sets of speakers instead of either/orif so, I would have given it five stars. A quality product at a good price.
It certainly isn't worth your money. San Diego I repeat: the Manual selection does not work (at least on my system). If they just ignore your inquiries, why even bother. According to the manual (just a pamphlet, actually) it's possible to deactivate the auto switching by placing a slide switch in the Manual position. Consider yourself warned. My intention is to simply open the unit and bypass the offending relay.
Nope, not on my unit. This is a horrible design. Briefly, this item is just not worth your time or effort. This amp seemed to fill the bill, but I was completely wrong. No matter what, it's certainly frustrating either way. The sound is harsh and artificial (you may disagreeit's subjective), but my main complaint is that this unit has a "feature" that allows it to sense audio input automatically and to switch on (and off). Oh, boy.
Click, click, click. That just doesn't work. After placing a complaint to customer support (and waiting an entire week with no response), I'm warning you before you choose this item: don't. And no sound at every other click. I've been using an old (~25-year old). If you don't know which end of a soldering iron to hold, however, you may find a solution like this a bit intimidating. unit and it finally died, leaving me looking for a replacement.
You can only imagine the irritation at listening to this and having it drop out and pick back up countless times in low-level passages or spoken audio. George Andrews. So, the result is that every time the audio drops below an arbitrary and unadjustable threshold, a relay drops out and the unit is silenced. based on that input. I bought this for only one reason: to take the audio from my computer and power my bookshelf speakers.
It is very easy to setup and use. We connected four Dayton Audio 2-way speakers to the amplifier behind a Behringer mixer. The sound quality was excellent. It has good sound quality also. The Amp-100 is a very good amplifier for the price.
All I can say is: These things are awesome, IF you use them correctly. If you are only plugging in 1 device, plug it in source 2. If your music or content plugged into source 1 all of a sudden gets quiet, you will hear another 'click' as it moves back to source 2. See, they are auto-sensing, so they default to source 2 and will always amplify what is on source 2, BUT if there is a signal on source 1 (not just a low level but a few db) you will hear a definite 'click' as it moves to source 1. This amp is great (I have 2 of them, 1 for the right/left stereo signals and the other one just for my center channel) but there is one thing that you HAVE to know before you setup this device. It makes very little sense, but I almost threw these things out the window. I made the HUGE mistake of plugging my equipment into source 1 and got all worked up that my equipment was cutting out when I would watch quiet scenes in the movies.
