Myryad MA500 blown channel

One of my channels is out on the Myryad MA500. What's my next step, as Myryad tells me there are no repair places in the US?

That particular channel is blown. These are not the easiest units to repair. Given that this is a commercial amp, I would recommend that this unit be brought to an authorized Crown service center for repair. Expect parts cost in the $50 range plus the labor charge.

Volume output level is low on all channel.

Please disconnect your speaker and using a good 1.5 AA cell test for a good response. if Ok connect to the amp and power. Hope you are using the right source input. If not give you input to another source input and check. If not it is important to check with a signal test for the failed section. Attempt this only if you are familiar or else ask a friend to test from the output backwards to find the section which is not responding and attentuating. It sould be a possible failure in the premap/ input selection or a biasing of these circuits. Hope this helps. Good day

You can try swapping the speakers over to see if the fault goes to the other channel. Remove the speaker leads from the input on the right channel and put them into the left channel input after removing the leads from those terminals, and if the fault goes there as well, then the problem is in your right channel speaker

Power requirement

David, rest assured you can purchase a VOLTAGE CONVERTER and use it overseas to adapt to other voltages. I would recommend you pick one up at any electronic dealers or check online as to what is available, GOOGLE: Power Converters Be sure to obtain one close to the wattage your unit requires

Amplifier problem

You may have a blown channel. Check for fuses inside but I don't think that it will help. Repair if the channel is dead is not worth doing as the amps value is probably lower than repair cost.
