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 VOLUME DOWN and turn the
system off. 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.
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
