It certainly isn't worth your money.I bought this for only one reason: to take the audio from my computer and power my bookshelf speakers. If you don't know which end of a soldering iron to hold, however, you may find a solution like this a bit intimidating. Nope, not on my unit. That just doesn't work.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. I've been using an old (~25-year old). No matter what, it's certainly frustrating either way.
Click, click, click. based on that input. 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. And no sound at every other click.I repeat: the Manual selection does not work (at least on my system).
This is a horrible design.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. If they just ignore your inquiries, why even bother.My intention is to simply open the unit and bypass the offending relay. Oh, boy.Briefly, this item is just not worth your time or effort. 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.
unit and it finally died, leaving me looking for a replacement. This amp seemed to fill the bill, but I was completely wrong.The sound is harsh and artificial (you may disagree--it'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). Consider yourself warned.--George AndrewsSan Diego
We connected four Dayton Audio 2-way speakers to the amplifier behind a Behringer mixer. It has good sound quality also. The Amp-100 is a very good amplifier for the price. It is very easy to setup and use. The sound quality was excellent.
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. 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.If you are only plugging in 1 device, plug it in source 2.It makes very little sense, but I almost threw these things out the window.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. 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.All I can say is: These things are awesome, IF you use them correctly.
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. 1. The main feature I liked was the automatic on/off setting so that it could be used in a GREEN environment---so to speak. You would figure that sound would come out of this thing no matter what the case when it is powered on. As an amp, sure it works.when it wants to. 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. 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. I bought this product for 1 of 2 uses. Use as a amp for a variable output from a MAC pro to drive 2 speakers.It FAILED in both instances. Use as a amp for a variable output from a flat panel tv to drive 2 speakers. 2. 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.
They don't even provide a switch on the front panel to manually switch LINES, you have to unplug your cables to take control. 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. LINE2 is the default input meaning whenever there isn't any signal on LINE1 the unit instantly switches back to LINE2. Otherwise a great product. 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. 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. 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. 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. It powers down nicely when no signal is sensed.
The issue is with the "instant" result.
