Troubleshooting

Many problems can be eliminated by 
re-checking the wiring and settings of the 
unit. If a problem cannot be solved using 
the guide below, please call the AudioCon-
trol team for further assistance, or e-mail 
us at [email protected]
1.  No Sound

a. Verify the front panel LED is blue.
b. Check that the Avalon G4 is not in 

standby mode (LED red).

c.  Check the input wiring from your 

sources to the Avalon G4 inputs.

d. Verify the source unit is operating 

correctly and playing, not paused.

e. Check the speaker connections on 

the rear panel are secure.

f.  If the unit does not power up at all, 

unplug the power cord and check 
the AC Power Fuse on the rear 
panel.

g. Check that the crossover settings 

are matched to your speakers.

2 .  Speaker channels are cutting in and 

out:
a. If using external volume controls, 

check that they can handle the 
power output.

b. Make sure the speaker impedance 

is not less than 4 Ohms, or 8 Ohms 
when used in bridged mono.

c.  There may be a short in the wires. 

Suspect a short if the problem hap-
pens only at higher volume levels.

3 .  Speaker Buzzing or Crackling at high 

volume:
a. Reduce any preamplifier/equalizer 

low-frequency boost.

b. Turn off your “Sounds of the  

Pacific Northwest” chainsaw and 
bacon-frying CD.

c.  Check that the crossover settings 

are matched to your speakers.

Mindfulness

1.  Take a deep breath in, hold it, and 

chant the specifications page.

2. Breath out slowly, while contem-

plating the joy of Avalon G4 owner-
ship.

4. Isn’t it nice to know that the 

Avalon G4 is so efficient that 
electrons can be free from the 
mundane life of room heating, and 
have more free time and energy to 
push the loudspeakers around and 
reproduce your wonderful music. 

3.  Breath in and out again as normal, 

and assume the “Salute to the 
Electron” position while reading 
the rest of this manual.

4. Do not try this on the bus home 

though. People might talk.
