1x40 Watt @ 8-ohm by bridge connection.

• Two stereo audio inputs, switchable by pushbutton, IR remote or RS232.

• Volume/Bass/Treble controllable by pushbuttons, IR remote or RS232.

• Microphone port can support b alan ced or unbalanced signal, and can

suppress the external noise effectively.

• Line audio output at 3.5mm jack, with controllable volume.
