Question about Yamaha P4500 Power Amplifier 2-Channel
When i power up the amp, the protect light comes on and does not go off. Ive left the unit on for some time and nothing changes. The amp is not connected to anything at the moment so there cannot be any short circuits or anything although when i originally removed the amp i realised someone in the venue had taken the speaker connectors out of the speak and twisted them together!!
Any idea how i reset the amp?
You only normally get that when the Volume over peaks, and the amp will automatically cut out to prevent it fron blowing the whole P.A up.
If you know it was working fine before the wires were twisted together, then best try undoing what was done, and making sure that the Amp's Volume is turned down to minimum.
