connection is wrong, a bass sound may become poor due to

reverse phase. Attaching the supplied colored speaker cable

labels to the + side on the both ends of each channel's cable

will help correct connection.

Up to two subwoofers with built-in power amplifier can

be connected to the subwoofer jacks. Set the cut-off

filter selection switch of the subwoofer to DIRECT. If the

subwoofer does not have a cut-off filter selection switch but

has a cut-off frequency adjusting dial, turn it to the maximum

frequency. If your subwoofer does not have builtin power

amplifier, you can connect a power amplifier between the

unit and the subwoofer.

can change it manually or by using automatic speaker

setting.

 Short-circuiting the + cable and - cable or contacting the

cable core to the rear panel of the unit may cause failure.

Also do not connect two or more cables to one speaker

terminal or one speaker to several terminals.

 Using a speaker with less impedance than the setting

may result in failure.

When using commercially available banana plugs:

Tighten the speaker terminals to the end and then insert

the banana plugs. Do not insert the core of speaker cable

directly into the hole for banana plug of speaker terminal.
