SUB INPUT:
This is your
s u b w o o f e r
channel where
the sub RCA
outputs from
your head unit
are inserted.
INPUT SELECTOR:
This tells the amp to play all channels even if only one pair of
RCAs is connected. EXAMPLE: If the head unit only has one
pair of RCA outputs then you must plug them into the CH1/2
connections and set the switch to 2. This tells the amp that you
are using one set of RCAs and it needs to play all five channels
regardless. If you have four RCAs, then set it to 4 and so on.

The gain knob is not a volume control.
It is designed to match the input level of
the amp to the output level of the source
unit. Over driving "clipping" the input
stage of the amp will cause damage to the
amplifier (please refer to table for setting).

POWER (PWR) LED:
When LED is on, it indicates that the
amplifier is ON and functioning properly.
PROTECTION (PROT) LED:
If LED comes on then you have an issue that requires
service. Turn off the amplifier and call Earthquake for
further assistance. See warranty for details.
