CONNECTING SPEAKERS ®
Speaker terminals
Connect front speakers (system A and/or B), a center speaker,
surround speakers and sub woofer to the corresponding speaker
terminals on the unit:
- the front speaker cords to the FRONT SPEAKERS terminals
- the center speaker cord to the CENTER SPEAKER terminals
- the surround speaker cords to the SURROUND SPEAKERS
terminals.
- for more powerful bass, the sub woofer (with a built-in amplifier,
Aiwa TS-W35 etc.) cord to the SUPER WOOFER Kl jack
Speaker impedance
• Front and center speakers
Use the same impedance speakers for both the front and center
ones.
The SPEAKER IMPEDANCE SELECTOR on the rear should be
set to the position that matches the impedance value of the front
and center speakers.
When using 4 ohm speakers, set the selector to IMP:40. When
using 8 ohm speakers, set the selector to IMP:8i2. Please unplug
the AC cord before setting the selector.
• Surround speakers and super woofer
The SPEAKER IMPEDANCE SELECTOR has no effect on the
SURROUND SPEAKERS terminals and the SUPER WOOFER
<1 jack. For the surround speakers and sub woofer, use speakers
of 8 ohms or more.
Connecting + to +, - to - terminals
To get the proper sound effect, the speaker terminals on the unit
and the speaker should be connected with proper polarity; the -r
terminal on the unit should be connected to the -r terminal on
the speaker (and - to -).
•
Front speakers
• Be sure to connect the speaker cords correctly as shown in
the illustration on the right column. Improper connections can
cause short circuits in the SPEAKER(S) terminals.
' Do not leave objects generating magnetism near the speakers.
