HOME THEATER CONNECTIONS:
Connect your main, center, and surround speakers to their respective output terminals
on the back of your Home Theater receiver. If you have either a powered subwoofer, or
a passive one, refer to their instruction manuals for applicable hook-up options.
After completing all connections, turn the system on, then GRADUALLY increase the
volume level. If there is no sound, distorted sound, or if the amplifier shuts itself down
after a few seconds, IMMEDIATELY TURN THE SYSTEM OFF and turn the volume
control all the way down. Then re-check your wiring for accuracy and for shorts
(adjacent bare wires touching each other). When everything sounds fine, keep the
volume reasonably low while you familiarize yourself with your system's various
controls and operations modes.
CABINET FINISH:
Your speaker cabinets require no maintenance under normal use. The cabinet surface
may, however, be cleaned by using a damp cloth. If you choose to use any kind of
cleaning agent (such as a non-abrasive glass cleaner) please be sure to test a small area
on the bottom of the cabinet first.
TROUBLESHOOTING
Many of the most common complaints about sound system performance can be
corrected simply. All that is required is to check out some basic things when a certain
type of problem is encountered. For now we'll assume everything is hooked up
properly, all equipment is turned on, and there is sound, but it just doesn't sound right.
In fact, often the problem lies in adverse room conditions or poor program material.
Following are some typical problems listed along with possible causes and solutions.
Common Complaints
Check For:
A. Bass
1. Too thin
Improper phasing, tone/equalizer controls, program material,
room positioning
2. Too heavy
Tone/equalizer controls, standing waves, corner placement,
program material
3. Too boomy
Lack of sound absorbent material in room, excessive bass
boost
4. Muddy
Tone/equalizer controls, poor recording, excessive hard
surfaces in listening room ("live room")
B. Treble
1. Too weak
Object obstructing speaker, program material, tone/equalizer
controls, speaker upside down, "dead" room conditions,
dirty tape deck heads
2. Too strong
Program material, room placement, excessive tone/equalizer
control boost, "live" room conditions
3. Raspy
Poor program material, defective amp or preamp, poorly
tuned station, dusty or worn turntable stylus
4. Hissy
Poor program material (recording quality), excessive treble
control boost, noisy amplifier, poorly tuned station, weak
station (use monaural for a stronger signal), poor tape
quality, poor record surface
C. Overall Sound Quality
1. Muffled
Program material, tone/equalizer controls, improper speaker
placement, excessive bass boost, extraneous noise (mower,
saw, appliance, etc.) speaker upside down, dirty tape deck
heads
2. Distorted
Program material, excessive tone/equalizer boost, excessive
volume, out-of-phase, extraneous noise, poorly tuned
station, damaged tape, dusty or bad stylus
3. Echoes
"Live" room conditions, tape print through, program material
4. Hum or Buzz
Faulty connecting cables, faulty amp or preamp, fluorescent
lighting, power tools, ungrounded turntable feedback,
incorrectly wired or faulty turntable cartridge
S. Crackling, Popping
Bad connections, dirty volume or tone/equalizer controls,
excessive tone/equalizer boost or volume level, worn album
or stylus (turntable users)
6. No Sound
Receiver's speaker switches (A & B or 1 & 2) off or
improperly set, wrong input selected, mute on, blown fuse or
short circuit at speaker terminals or amplifier output
terminals
