Connecting speakers

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.

Caution
Do not let the bare speaker wires touch each other as this could damage the amplifier and/or speakers.
When connecting a subwoofer (not included in this system)
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 both the
amplifier and subwoofer are contained in the same unit.
* The SUBWOOFER OUT terminal outputs low frequencies from both the left and right channels. (The cut-off
frequency of this terminal is 200 Hz.)
