Description

This two channel Class D amplifier board employs a topology featuring TDA7492 amplifier IC which achieves high efficiency. Each channel of the amplifier board delivers up to 50 watts @ 6 Ohms. Heatsink with attached fan provides a drastic reduction for the system temperature. Over temperature protection circuit is included to extend the longevity of the amplifier board. Four fixed gain settings are available to allow for volume control at the source, and stereo RCA line-level inputs are pre-attached. Pre-drilled mounting holes work as a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection.
