Just bought a brand new AudioSource Amp100 2-channel.
When I plug an iPod or a TV into Line 1 In, and the volume of the source sound dips low, the amplifier clicks and the sound cuts out. Quiet parts of movies make it happen. Quiet parts of songs from the iPod make it happen.
When the volume of the sound source increases again, the amplifier clicks and the sound returns.
This only happens with Line 1 In, never with Line 2 In.
Is there something wrong with the amp, or with what I'm doing>

Re: Amp 100 Line 1 in problem
That is a strange problem you have indeed. The amp switches automatically from one input to the other, with default to input 1. You say the source sound dips low, is this a source from another integrated amp, where the AMP100 is working as a zone 2 device? . Are you using it as a zone 2 amp, and plugging other devices in the zone 2 area? and lastly, are you using auto on functions? Let me know, and we may be able to figure it out for you.
If it is new, then it may be worthwhile swapping it over for another by the supplier of the amp

I would check if the amplifier somewhere gets hot. Most likely with a certain temp the amplifier will go into protection, Avoiding damage to the vital parts.
When you can find the place where it becomes hot, perhaps you can see if a transistor, or am integrated circuit is not correctly fastened. Before fastening it, perhaps you should apply cooling paste. (Like you use between a microprocessor and the van)
Perhaps it is only running hot, because you want to much power?
The problem is not due to how the circuitry is configured; the problem is due to failure of some element in the right channel amplification circuit. This will require detailed troubleshooting to correct.
When the fuse keeps blowing you have an overload. The cause of which is either in the power supply or the main amp. It will almost for certain be a semi-conductor of some type acting like a piece of wire. A multi meter will show up a most faulty parts with this condition. On the Ohm setting applying the test probes to transistor terminals (E,C,B) you will get a responce like you had touch the probes together! The power transistors or whatever is on the heatsink are good at going short circuit, as people often short the speaker wires together.
Don't forget to check for burnt or damaged parts too.
As a rule of thumb with transistors when testing on a meter (1K setting) (best with moving coil scale meter than a digital) apply to base (B) and then to C & E you should get an ohms reading. If you don't get any reading (both ways) it's dead (open) and if the meter goes full scale - it's shorted.
Is the amp already used for L R? If so, you either need another amp for center, or set your Sony for stereo mix down. I have mixed the center channel into my main LR in the past and found there were terrible phase cancellations, so I suggest you switch to Stereo, or use a separate amp.
