Remote connections between Yamaha products
An infrared signal transmitter is not required if you are using
Yamaha products that support remote connections, as the unit
does. You can transmit remote control signals by connecting the
REMOTE IN/OUT jacks with monaural mini-jack cables and an
infrared signal receiver.
