The C61R provides six analogue outputs to allow you to connect to
six power amplifiers and passive loudspeakers, or 300 Series Active
and Passive Installation Loudspeakers powered by the G41 Active
Crossover Amplifier.

• Connect the LEFT and RIGHT analogue outputs to the power

amplifier inputs for the main front loudspeakers.

• Connect the SURR L and SURR R analogue outputs to the power

amplifier inputs for the rear loudspeakers.

• Connect the CENTRE analogue output to the power amplifier

input for the centre loudspeaker.

• If the system includes a subwoofer connect the SUB analogue

output to an active analogue subwoofer, such as the Meridian
SW1600.
