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 Balanced connection Trigger connection You can connect a CD player or network player that features XLR-type balanced output jacks to the BAL input jacks of this unit. Use XLR-type balanced cables for this connection. ATTENUATOR selector: Enables you to set the allowable input level at the balanced input jacks. Select ATT. (−6 dB) if the audio output from the connected component sounds distorted.
Remote connection ■ Operating the unit from another room 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. Rear panel of this unit ■ Remote connection between Yamaha components If you have another Yamaha component that supports remote connections, an infrared transmitter is not necessary.
Connections Connecting the power cable 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.
