Dynacord PowerMate 1000-2


Recommended Posts

Hi all, I have Dynacord PowerMate 1000-2, I had a gig and everything was ok, left over night in the van and next morning ones is powering on, straight away goes in to protection mode. Is any one has some ideas what's happens.

Many thanks

A couple of options...


1) There are a couple of T4A fuses that feed to the +/-15V rails. Check they are OK.


2) One of the power amplifier channels has gone DC


3) There is a fault in either the fan circuit or the transformer over-temperature circuit.


4) There is fault in the protection circuit itself so that it is staying in the power-on mute condition.
