The Sub Out is for connecting to the LFE/Sub input of an active subwoofer.
The diagram below shows how to connect the AXR to an active subwoofer via the LFE/Sub input on the subwoofer.
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 front panel and remote control allows the two sets of speakers to be toggled on and off. Refer to the Front Panel or
Remote Control section of this manual for more information on the Speaker A/B operation.
