QSC PLD4.5 4-channel amp

Re: QSC PLD4.5 4-channel amp

Just a side thought, Check all your calculations before you sit down and invest in 4 channel amplifiers. I've found that the Crown 4 channel amplifiers like to draw a lot of amperage when really being pushed and then shut down due to the fact that they were trying to draw more than the circuit would allow. just some food for thought. I would always prefer Two 2-Channel amplifiers over One 4 channel amplifier.

Amps don't just shut down because they are overdrawing, Cuicuit breakers pop, I am guessing that is what you mean by the amp shutting down?

The crown that I would guess you are referring to (iTech 4x3500) should be plugged into a 30A circuit according to spec.

The peak current draw on a PLD 4.5 is 8 amps, Mine tend to draw between 4 and 5 when driving them hard. Being able to have 8 bi amp mixes in 8 rackspaces instead of 16 is quite a nice savings on space and weight, well worth it IMO.

If you run a long thin power cable, you will get significant voltage drop on the line. When voltage drops too far, the amp goes into protect and shuts down. This can happen without tripping the breaker on the line.


Key when working with high power amps is to make sure you supply enough power to keep them happy. Heavier cables are always better.

Not quite-proper circuits that match the needs of the high power amplifiers along with cables that are matched to those needs. That is what is important. Cable size is pointless if the circuit isn't properly sized.
