Connections
1/2"-5/8"(12-15 mm)
Cut and remove the plastic coating from the end of the
speaker cable, twist the core and connect it to the terminal.
Make correct connection between the unit's jacks and
speaker's jacks (+ to + and - to -) for each channel. If
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. The
subwoofer jack supports connection of a subwoofer with
built-in power amplifier. 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 built-in power amplifier,
you can connect a power amplifier between the unit and the
subwoofer.
• The speaker setting is 7.1 ch at the time of purchase. You
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 cable core directly into the
hole for banana plug of speaker terminal. (North American
