20 Most Recent AudioSource AMP-100 2-Channel Amplifier Questions & Answers

Hi JamesOBrien

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? To loud.

Ground and Remote wire ? Common issues I have run into.

How loud do you expect it to be?

More watts doesn't mean more loud but it gives you more headroom for cleaner reproduction of very loud passages. Distortion will kill a speaker faster than clean signals will.

this is a - large fuse type - all car spare parts carry this fuse
You need a large - 3ag - 5a = 5 amp fuse
3ag-5a = 3ag (large fuse ) 5a - 5amp

When the fuses blow like that suspect an overload in either the power supply or main amp stages. I think you might have damaged one or more of the output devices. They can develop faults quick if you're using the wrong type speakers or have faulty wiring to them. The main cause of fuse blowing is a semi-conductor device that is acting like it is a piece of wire. For instance an output transistor when connected to a multi-meter on the ohm scale, will show a full scale deflection, just like if you had touch the two test probes together.

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.

the amp should have a sub out if not ,you can check if the sub can take a speaker level input so that you can connect one or both speakers to the sub and it will take the signal from there ,please send the sub model no ,i can track the inputs provided

It is normal for power amps to get warm. Overheating can be caused by deffective speakers, or internal leakage on the transistors. Does is produce normal sound?

Hi

re install the audio driver to come back the sound. but first remove the virus before you proceeds to install

Thanks!

CD player to any audio in. Tape deck requires a dedicated tape in tape out connection found in older amps/receivers.

Yes you can but I will have to know the inputs and the outputs you are dealing with to advise you further.

If I where you to be on the safe side, I would order a brand new transformer. Transformers are safety parts anyway and should also be replaced by exact types recommended by the manufacture of the amp. It's not worth tampering with the thing yourself only to have it burn your house down a few days later for want of spending some money on a new one!
