AudioSource AMP-100 2-Channel Bridgeable Stereo Power Amplifier

I bought this product for 1 of 2 uses.
1. Use as a amp for a variable output from a flat panel tv to drive 2 speakers.
2. Use as a amp for a variable output from a MAC pro to drive 2 speakers.

It FAILED in both instances. As an amp, sure it works...when it wants to. The main feature I liked was the automatic on/off setting so that it could be used in a GREEN environment---so to speak. That part works....the only PROBLEM is when you are watching TV and a slightly silent moment on a show appears....no sound for 2-3 seconds. The AMP cuts out....plain and simple.

Now on the MAC side - you figure its a computer, it only makes sounds when it needs to and so the amp should be ready. Well, the green light is on but no one is home....no sound until you reset the amp.

At this point I figured maybe the auto on/off function was to blame....so I put the amp in manual mode where if its on its on and if its off its off......simple. You would figure that sound would come out of this thing no matter what the case when it is powered on. Sure enough...it gives you sound and then it cuts out...and then it gives you sound for a minute or two...then it cuts out....then another 5-10 second wait....

Forget it...save the $100 and buy something that works. I am sure there are other products out there.

Please correct me if I am doing something wrong...but I read the manual and I did it right....having some sense of this stuff I dont think I could have done it any better.

Hope this helps.

This product had great potential and it does everything promised as long as you only use 1 source and you attach it to the LINE2 input. LINE2 is the default input meaning whenever there isn't any signal on LINE1 the unit instantly switches back to LINE2. The issue is with the "instant" result. When I play a DVD movie through LINE1 the AMP100 annoyingly switches back to LINE2 every time the audio goes quiet - even in between dialog. The switch makes a discernible "click" and usually does not return back to LINE1 right away so some of the audio you hope to hear is lost. Same issue with music tracks - during quiet passages the AMP100 switches back to line1 and if there is anything playing on LINE1 your other audio source starts chopping in and out. I have two AMP100's and they both operate this way. I spoke with Audio Source tech support and they acknowledged this shortcoming and tried to push me to buy the AMP200 which apparently has a time delay that prevents this undesired chopping of content that is connected to LINE1. They don't even provide a switch on the front panel to manually switch LINES, you have to unplug your cables to take control.

Otherwise a great product. It powers down nicely when no signal is sensed.

I was looking for a specific solution for my outdoor speaker needs; I wanted to run my outdoor Yamaha speakers in mono mode as they were situated in different areas of the backyard and stereo would not have worked very well. After a bit of online research I came upon AudioSource Amps. At first glance the entry level 100 appeared rather basic but I didn't need an additional receiver or a powerhouse amp (it's just for background music) so it seemed to be the right solution. I read numerous other reviews that indicated I was on the right track.

Amazon shipped quickly and I was self installing. The printed manual wasn't crystal clear - to me at least - and as I didn't want to blow my speakers due to miswiring I called in to the free support line. I was quickly connected to a live person (who wasn't located on the other side of the world) who confimed that I was wiring correctly for a mono application and the rest of it was easy.

I'm very pleased with the 100; I only run it at 1/4 volume and that's plenty for outside listening. Any more and conversation would be difficult and the neighbors might start to get annoyed. It's turned out to be an affordable, simple solution for me.

My GF bought this amp as a present for me, and now she's very unhappy. We opened the shipping box, which was 5 times the size needed, removed the amp and hooked it up. We couldn't get it to do anything advertised! Nothing hooked up to it produced any sound. Only the green "ON" light and the red speaker lights worked. I called the 800 number for tech support at the mfgr. of this AudiolessSource Amp 100, and, after the normal recorded voice menu, when transferred, the phone just rang and rang. No support or customer service!! It went back today!!

Used in the home office with two inputs, one from a DVD/CD desktop player and another from my computer SoundBlaster card, through to two Sony speakers. No B speakers hooked up. The performance is excellent and the line sensing feature works perfectly. The system turns the green power light to red (same as the line A regular color) when there is no line feed of sound. The only time this has not worked well was on just one YouTube video I was watching where the sound was very weak and the amp kept sensing it should shut down. Other than that one time, with the DVD/CD desktop and the sound card feeds, it works really good. Fry's Electronics was $149 for this, and when I got it on Amazon it was $84.99 plus free shipping. I recommend this if you want a nice amp for your computer or a remote amp for some back room house speakers.
