A6 INSTALLATION MANUAL
Symptom Possible Cause Solution
Audio “Hum” 1. Ground potential difference between
source components (ground loop)
2. Faulty/damaged cables
3. Faulty wiring
1. (a) Test AC outlet using ground tester.
(b) Reverse the AC plug of compo-
nents with non-polarized ends plugged
into the same outlet strip as amp.
2. Check source equipment cables for
damage and faulty connections.
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
2. Defective/incompatible speaker
3. Volume control wired incorrectly
4. Volume control Impedance Match
settings incorrect
1. Reduce gain to the channel in ques-
tion.
2. (a) Check for physical damage to
speaker.
(b) Ensure speakers have appropriate
power rating for amplifier.
(c) Ensure speakers are rated @ 8
Ohm impedance. This amp is compatible
with speakers with 8 Ohm impedance or
greater.
3. Check for proper input/output con-
nections at volume control. Input comes
from amplifier, output goes to speakers.
4. Verify/correct Impedance Match set-
tings.
Audio is Unclear, Bass
Response Low
Speakers out of phase Verify that + of amplifier goes to +of
speaker and - of amplifier goes to - of
speaker on ALL speaker leads.
Incorrect Source Playing
on Speakers
1. Source connected to wrong
input of amplifier
2. Speakers connected to incorrect
speaker outputs
3. DIP switches set incorrectly
1. Verify/correct input connections.
2. Verify/correct speaker connections.
3. Verify/correct DIP switch settings.
Amplifier Will Not
Power Up
1. Power switch is Off
2. Circuit breaker tripped
1. Turn switch On. Switch is located on
the back of unit.
2. Reset circuit breaker. Ensure that
combined current draw of all devices
on circuit does not exceed the circuit’s
capacity.
