Audio (Continued)
Symptom
Possible Cause
Solution
Audio hum
1. Ground potential difference between
source components (ground loop)
1. (a) Test AC outlet using ground tester.
(b) Reverse the AC plug of components with non-polarized
ends plugged into the same outlet strip as amp.
2. Faulty/damaged cables
2. Check source equipment cables for damage and faulty
connections.
3. Faulty wiring
3. (a) Make sure volume controls are not hooked up
.backwards.
(b) Check for shorts in wiring
(see item 2 in “No audio…”).
Distorted audio at
normal volume levels
1. Input gain set too high
1. Reduce gain to the channel in question.
2. Defective/incompatible speaker
2. (a) Check for physical damage to speaker.
(b) Ensure speakers have appropriate power rating for
amplifier.
(c) Ensure speakers have at least 4 Ohm impedance. This
amp is compatible with speakers with 4-8 Ohm
impedance or greater.
3. Volume control wired incorrectly.
3. Check for proper input/output connections at volume control.
Verify that the input comes from amplifier and the output
goes to speakers.
4. Volume control Impedance Match
settings incorrect.
4. Verify/correct Impedance Match settings.
Audio is unclear,
bass response low
Speakers are out of phase
Verify that + of amplifier goes to + of speaker
and - of amplifier goes to - of speaker on ALL speaker leads.
