Speaker B connections
The Speaker B connections on the back of the amplifier allow for a second
set of speakers to be used (i.e. speakers located in another room).
The Speaker A/B button on the remote control allows the two sets of
speakers to be toggled on and off. Refer to the Remote Control section of
this manual for more information on the Speaker A/B operation.
Set either A or B, or both A and B may be selected for use.
Note: When using two pairs of speakers, use speakers with a nominal
impedance of 8 ohms each.
