My Jamo MPA-101 amplifier is clicking loudly but does not work through my household speakers!

Buy a Boston Acoustics, "Soundfreaq" (place low), "Big Jambox" (place on desk) or something. They can get plenty loud without waking up the whole neighborhood. List is roughly in the order of costs. I ended up using some Jamo speakers for my surround system in the family room. Onkyo THX amplifiers are nice.

Just a suggestion - does the orange light mean a short circuit somewhere?

replace all caps in the power supply section, or send it to me , 727-289-9746

Refer to the applicable Jamo manual.

Try to trace the fault systematically from one end of the system to another, starting with something that you know is working

1. Start by checking your sound source (cd player or whatever) is working by connecting it to another amplifier or computer.
2. Check the connecting cable is working from the sound source to the amp and is not shorted out.
3. Make sure your loud speakers actually work (briefly shorting a 1.5 volt AAA battery across the speaker terminals should produce a crackling sound without doing any damage)
4. Check loudspeaker cables are properly connected to output connectors and are making a good contact.
5. Try connecting something like your computer speakers (or use the microphone in jack on the computer itself) to the line output socket of the Jamo. If you can get some sound this way it would suggest that the internal output overload protection fuse may have blown. You will need to open the case to access this. NOTE if your JAMO is still in warranty take to authorised repairer otherwise you may invalidate your warranty.

This will depend on whether your sub-woofer is powered (has it's own built in amplifier) or not. If it is not powered it will need connecting to an amplifier. If it is powered you will need a line level output either on the amp or the mixer.
Many modern amplifiers (and some mixers) have a dedicated output for sub-woofers in which case this is the best place for it because the higher frequencies will have been filtered out.
Some high quality amplifiers like the JAMO MPA 101 have a filter switch and adjustable filter level for powering sub-woofers. You then just connect the speaker to the speaker terminals in the normal way.

Otherwise on a p.a. mixer you could use the main output, one of the auxiliary, monitor or sub-mix outputs. If you are not using the main output you will need to route signal to the appropriate output accordingly. Either way your output signal will cover the full frequency range - your subwoofer may have built in filtering or you may need to use some sort of crossover to split the signal between the sub-woofer and the rest of your speaker system.

The 201 is 100w in to 4ohms and the 101 is 50w into 4 ohms other then that there the same

Check the small electrolytics on the power supply board for high ESR, Very common problem on these amps. Protect circuit stays latched due to high ripple from PS.

I can almost guarantee that you'll find bad electrolytic caps on the power supply board to be the cause of the problem. I've seen several of these with the same problem. The protect circuit stays latched due to excessive ripple.

Hello, is this a Radio Shack PA amp or Jamo amp? The unit is probably in "Protect" mode. Is this a PA system or a receiver...receivers have a protection circuit that will not let the speaker relay activate if the amplifier output section is shorted and sending voltage towards the speakers...so they won't fry!!The speaker relay should activate within 3 to 5 seconds if your output section is ok.
