Installation Manual
3. Source Clip LED is on:
a. Turn down the level of the audio signals entering the Epicen-
ter. The Epicenter analyses the incoming audio and detects if
the signal is clipping. Make sure the settings in other equip-
ment in your system, such as EQ controls, are not over-done
and clipping the signals.
4. Speaker channels are cutting in and out:
a. Make sure the speaker impedance is not less than 1 Ohm.
b. There may be a short in the wires. Suspect a short if the prob-
lem happens only at the highest volumes.
c. Make sure the subwoofers are not being overdriven, beyond
their recommended level.
5. Speaker Buzzing or Crackling at high volume:
a. Reduce any preamplifier/equalizer low-frequency boost.
b. Check the Epicenter’s Source Clip LED is not on.
c. Check the Epicenter’s Protection LED is not flashing a code
such as “under-voltage.”
d. Try playing something different and see if it occurs again.
e. Adjust the Epicenter so the levels going in (Source Clip) and
going out (Gain Maximized) are optimized.
f. Note: Scratching your ear with your car keys may cause your
head to start up.
6. Should I notice a blue glow coming
from within the unit, near the heat-
sinks?
a. Yes. Do not be alarmed. There are blue LEDs inside the ampli-
fier that are on when the unit is on. They also blink possible
winning lottery numbers during power-up, and if the protec-
tion circuits detect a fault.
