The six (6) channels of the CAV-75 are divided into three (3) groups. These groups can be
operated and configured independently _ Channel-1 with Channel-2, Channel-3 with Channel-4,
and Channel-5 with Channel-6. When in bridged mode, the inputs of CH-1, CH-3 and CH-5 are
used respectively (as marked above the jacks). The unused inputs of CH-2, CH-4 and CH-6 are
automatically disconnected when configured in bridged mode. The following steps should be
performed to switch between NORMAL and BRIDGED modes.
1) Turn OFF the unit and remove all connections, including the AC linecord.
2) Remove top cover with the Allen key supplied.
3) Locate the input board(s) of channels to be switched. (see fig.1 page 7)
4) Locate and set jumpers to the desired operation mode. (see fig.2a,2b page 8)
5) Replace and secure the top cover.
6) Reconnect all cables. Make sure the input and output connections are according to the
operating mode. (see fig.3a&3b page 9)
Please read through the previous normal section for general notes on securing good connections,
and safety tips.
CAUTION: Please remember that the negative output connection of a bridged amplifier is NOT a
ground. Do not use a "common ground" or switchbox set-up. Do not use with electronic
crossovers which have a common ground.
REMOTE CONTROL: (optional)
With a simple connection from the receiver box to the remote jack at the back of the
amplifier, (see Fig.2 page 8) the power amplifier can be turned ON/OFF from a distance (or from
another room).
