SETTING UP THE SW10 AND SW12
After making all the connections and calibrating the loudspeakers, set up the SW10 and SW12 by
performing the following steps (see CONTROLS AND CONNECTORS on page 7 for information
on control operation):
1. On the rear panel, set the (Auto) POWER switch to ALWAYS ON or MUSIC/VOLTAGE
SENSE. Depending on your application.
2. On the front panel, set the following controls (and switches) to their initial positions:
• LEVEL control = 5
• LOW PASS FREQUENCY control = 120 Hz
• PHASE control = 0°
3. While playing a favorite music track, adjust your system's volume control to a
comfortable level and listen to the bass level at your favorite listening position
(e.g., couch).
4. Continue listening to your favorite music and movie sources. If you want a more solid-
sounding bass (with less overtones), try moving the LOW PASS FREQUENCY control
toward the lower frequencies. Experiment with different frequency settings until you
find one that sounds best. If needed, readjust the LEVEL control (see step 3).
5. Continue listening to your favorite music and movie sources using the appropriate
setting for LEVEL SETUP. Try experimenting with the PHASE control until you find
its optimum setting. Depending on the SW10 and SW12 placement, the bass should
sound more pronounced when the phase has been optimized.
CHECKING PHASE ON THE SATELLITE LOUDSPEAKERS
Loudspeaker wire has two conductors. On applications with satellite loudspeakers, one conductor
is attached to a component's negative (–) terminal, while the other is attached to a component's
positive (+) terminal. Usually, the wire is marked for your convenience, but the marking can be
done in the following different ways:
• Stripe on one wire
• Ribbed area you can feel on one conductor
• Different colors of metal wire on each conductor
• Fabric strand or string wound into one of the conductors
