Using the A0302 with the A0240

The A0302 is the perfect complement to Channel Vision’s A0240 amplifier. It

can utilize the Amp-Link connection, which provides a clean way to interrupt

the speaker-level audio from a low-power system and output 40 Watts per

channel to the speakers.

Using the input switch

This switch allows you to select which input connector you want to use to route

signals to the RCA outputs and the Amp-Link connector.
