Connections

Caution
Do not let the bare speaker wires touch each other as this could damage the amplifier and/or speakers.

When connecting a subwoofer (separate purchase)

You may wish to add a subwoofer to reinforce the bass frequencies.
When connecting a subwoofer to this system, connect the SUBWOOFER OUT terminal of this system to the INPUT terminal of the
subwoofer.
* Ordinary subwoofers, including the Yamaha Active Servo Processing Subwoofer System, are designed so that the amplifier and

subwoofer are in the same unit.

* The SUBWOOFER OUT terminal outputs low frequencies from both left and right channels.

(The cut-off frequency of this terminal is 200 Hz.)

Connecting speakers

Connect the speakers to the corresponding speaker terminals on the rear of the main unit respectively by using the speaker cords.
Make sure that the polarity of the speaker cords is correct, that is the + and – markings are observed. If these cords are reversed,
the sound will be unnatural and lack bass.
