It also has a signal-sensing auto turn-on feature for convenience and is protected from short circuit issues.
Expect Extensive Full-range Frequency Performance
Thanks to its Class-A/B amp design, the Memphis Audio PRXA300.4 can deliver a power output of 50 Watts RMS at 4 ohms and 75 Watts RMS at 2 ohms per channel. With its frequency response of 20 Hz to 20 kHz, you can expect extensive full-range frequency performance from the amplifier.
