OPERATING THE SUBWOOFER
Power Up
1. Plug all components into an A.C. outlet.
2. On the subwoofer input panel, setthe POWER switch to ON. The power
LED on the input panel will display a RED light. The red LED behind the grille
indicates that the subwoofer is on standby.
3. Turn on the power to the audio components.
Listening to Your System
1. Turn the VOLUME control on your preamplifier to a comfortable listen-
ing level and begin playing a record, CD, or cassette that is rich in bass
information.
2. Experiment with the controls on the ECU until you are pleased with the
sound. The bass should enhance but not overpower the rest of the music.
3. Experiment with the placement of the subwoofer. Minor position adjust-
ments may produce results that are even more pleasing.
The 0 to 180° phase control located on the front panel of the ECU should
be rotated to optimize the blend of the subwoofer and satellites. There will be
a position within the full rotation of this control which will yield the best results.
As you rotate the control listen for the following:
1. Maximum bass output
2. Greater low frequency definition
3. A seamless transition between the subwoofer and the satellites.
You may experience all three sonic characteristics or only one or two. The
phase control may be set anywhere within its rotation for optimum perfor-
mance.
Impact of Tone Control on Your System
The tone controls on your audio components should be used with the
utmost discretion. Excessive boost can demand hundreds of watts in the bass
region. In the flat position or with the tone controls switched out of your system,
as little as 10 watts can produce impressive and realistic listening levels. The
remaining power amplifier capacity is in reserve for power peaks on sharp
transients and powerful crescendos. With the flexibility of the ECU, you should
be able to leave the bass control of your preamp at the flat position.
CARE OF THE ENCLOSURE
The enclosure of your subwoofer is finished with a durable, high-gloss,
scratch-resistant polyester resin. The finish should be kept clean by oc-
casionally dusting with a lint-free cotton cloth. Fingerprints and other minor
blemishes may be removed with a lint-free cloth dampened with ammonia-free
window cleaner. Do not use abrasive or chemical cleaners.
The grille may be cleaned by gently vacuuming with a furniture brush
attachment.
IN CASE OF TROUBLE
If the subwoofer sounds distorted, stops playing, or otherwise seems to be
malfunctioning, first determine if the problem is in the subwoofer, wiring, or
other audio components. If the problem also affects the satellite speakers, the
cause is most likely in your electronics. If it is only noticed in the subwoofer,
make sure that all connecting cables are correct and in proper working
condition. Make sure the subwoofer and ECU are plugged in and turned on.
Check the subwoofer A.C. fuse. If everything seems to be in good working
order and the subwoofer still malfunctions, DO NOT ATTEMPT ANY
REPAIRS! Contact your dealer for the nearest authorized Infinity Service
Center.
