NOTICE If a component is connected to the MAIN IN jacks, the unit’s volume level will be fixed. Therefore, do not connect a CD player or other components that do not feature volume adjustment to the MAIN IN jacks. Otherwise, a loud sound may be emitted, resulting in malfunction of the unit or damage to the speakers. External amplifier or active subwoofer Speaker A (L channel) - + – + Speaker B (L channel) CD recorder, tape deck, etc. Preamplifier, AV amplifier, etc.
Connections Connecting speakers ■ Using speaker cables Note • Because this power amplifier is of the floating balanced type, the following connections are not possible. - Connecting between two “+” (or two “−”) terminals of the left and right channels (Fig. 1). - Connecting each “−” terminal of the unit’s left and right channels to the opposite channel speakers (cross connection, Fig. 2).
Bi-wired connection Note All connections must be correct: L (left) to L, R (right) to R, “+” to “+”, and “−” to “−”. For information regarding the connection procedure, refer to the owner’s manual for your speakers. ■ Using banana plug cables (Models for U.S.A., Canada, Australia, China, and Taiwan) First tighten the knob on the SPEAKERS terminal, and then insert the banana plug into the head of the knob. A bi-wired connection separates the woofer from the mid and high ranges.
Connections Trigger connection Remote connection You can connect a Yamaha AV receiver or other component that supports the Trigger function. You can control this unit in sync with a connected component. ■ Operating the unit from another room Rear panel of this unit If you connect a commercially-available infrared receiver and transmitter to the unit’s REMOTE IN/OUT jacks, you will be able to operate the unit and/or external component from another room, using the supplied remote control.
Connecting the power cable ■ Remote connection between Yamaha components After all connections are complete, plug the power cable into the AC IN connector of the unit, and then plug the power plug into the AC outlet. If you have another Yamaha component that supports remote connections, an infrared transmitter is not necessary. Connect an infrared receiver to the unit’s REMOTE IN/OUT jacks, as shown below. Up to 3 Yamaha components (including this unit) can be set up for remote connection.
