Answers to some questions about the SR series digital amplifiers

Q: What is the idle power consumption of the amplifier?

A: 4-channel: 137W; 2-channel: 117W.

Q: What is the maximum AC input at 120V and 240V?

A: 120V/90A; 240V/45A.

Q: 30A circuit: If the amplifier operates on a 115/120V, 30A circuit, what is the actual maximum power/current it can draw? Are there any internal limitations?

A: The internal power supply circuitry is limited to 60A RMS continuous current and 110A peak transient current. A 30A circuit alone is insufficient to fully utilize the amplifier's power output.

Q: If the amplifier supports operation at different voltages, is it sufficient to simply change the AC power cord/plug, or does the internal power supply require reconfiguration or modification? Please specify if a voltage selector or other configuration steps are involved.

A: Only the power cord needs to be changed.

Test results: Operation at 220V results in lower heat generation and greater power supply stability compared to 110V.
