Connect an amplifier and surround sound speakers using a sender
and receiver.
Building a 7.1-channel home theater system
To build a 7.1-channel home theater system, connect a Receiver to
your left surround speaker and left surround rear speaker, and then
connect another Receiver to your right surround speaker and right
surround rear speaker the same way.
Connect an amplifier, surround speakers, and surround rear speakers
using a sender and two receiver units (RF-RBREC - sold separately).
Note: When setting up your system, you can identify which channel is connected to
which receiver by pressing the source button. The channel transmitting will flash it's
source LED briefly so you can visually identify the Input A or B to the correct receiver.
Expanding the system in zone B
To expand your listening areas in other rooms, install additional
receivers (sold separately) possibly in a bedroom, kitchen and garage,
or on the patio as you prefer.
