This high-efficiency, 18W power amplifier features a balanced line-level input, 8ohm output, integral audio compressor and automatic sleep mode. The sleep mode conserves power when the audio input falls silent. Connections are made via a detachable terminal block connector. A digital timer switches the class D output stage off so the unit consumes less than 1W of power. The sleep mode timer can be set to 5, 15 or 25 minutes or off (amp always on). Upon detection of an input signal, the amplifier is restored to full operation within 150 milliseconds. The amplifier's frequency response is 20Hz to 20kHz. Also available as the FP-18H, which is a high ambient temperature version that will operate in ambient temperatures up to 70 degrees Celsius.
