Orion Car Audio DEQ 30 - Manual (Page 14)

8. Disconnect the output of the DEQ 30 from the
rest of the system.
9. Leaving the source units volume control alone,
slowly increase the left gain of the DEQ 30 until
the “CLIP” LED indicator becomes illuminated.
The output of the DEQ 30 is currently clipped.
10. Turn down the left gain control until the LED
goes out. HINT! The closer the gain is set to the
point where the LED goes out the better signal-
to-noise ratio and channel output balance you
will have. The output of the DEQ 30 is now
optimally set for the left channel.
11. Repeat steps 9 & 10 for the right channel gain.
Your DEQ 30 is now perfectly level matched for
your system. Maximum output on your CD
player will yield more than 4 volts rms (per
phase) output. The DEQ 30 is also optimally
configured for digital output.
”CLIP“ LED ILLUMINATES WHEN
INPUT IS OVERLOADED.
Non CD Setup: Set source unit to 3/4 volume with
dynamic content music. Set amplifier gains to their
minimum position. Slowly turn up the gain controls of
the DEQ 30. Be careful not to exceed the maximum
output of the DEQ 30. Maximum output is exceeded
when the “CLIP” LED indicator is illuminated.
