Can someone tell me why my crown macro tech 2402 is shutdown on Ch 2.... With the back board disconnected I'm getting 100 volts + on one of the rail and 9 volts - on the other
Crown Macrotechs use two floating rail power supplies, one for each channel. Measurements of supply to ground may not tell you anything useful. Measure each OUTPUT with respect to its ground, ahead of any protection relay.
