Controls and Functions
For use as a dedicated subwoofer channel, set the filter switch to the "LPF" (Low Pass Frequency).
Adjust the variable crossover frequency with control knob as desired. The amplifier input circuit filters out
everything above 50Hz ... 150Hz (dependant on the adjustment of the frequency control), so only the
lowest bass notes are amplified.
The sub sonic control will cut all frequencies below what it is set to from going to your sub(s). This will
prevent your subs from playing any frequencies that may harm them.

9. Bridged Connection
This is the connection used to bridge 2 two of the same class D amplifiers together. Later in this manual it
is explained how to bridge the amps and what settings to use.
CLIPPING INDICATOR
Included on the front of this amplifier is a clipping indicator. You will
notice that the lights on the front of the amplifier light up blue. This
happens during normal good operation. If the light start to turn red, it
indicates that the amplifier is clipping. This can lead to permanent
damage to both your amplifier and any speakers hooked up to it.
Clipping can be caused by low voltage supply to the amplifier, having
the gain / level or bass boost setting adjusted to high, or too low of a
ohm load causing the amplifier to overdrive itself.
