LED TUBE INSTALLATION (OPTIONAL)
These Polk Audio amplifiers have been designed with
a custom heat sink that can accommodate two
(optional—not supplied) VARAD LED tubes.
1. Before installing the LED tubes, remove and discard
the mounting feet from the VARAD LED tubes.
2. Slide each LED tube assembly into your Polk Audio
amplifier heat sink. Ensure that the LEDs are facing
out for optimal visibility. The wires from the LED tube
assembly should be on the signal input end of the
amplifier. The Black wire from the LED tube is ground
and the Black/White wire from the LED tube is power.
3. Run the two wires from the tube assembly and
connect them to the 4-pin LED/FAN input connec-
tor. Refer to the LED/FAN harness diagram given
earlier in this manual.
NOTE: If the optional fan IS NOT being used, we recom-
mend that the second LED tube be wired to this circuit.
If the optional fan is being used, we recommend that the
second LED tube be wired in parallel with the first LED tube.

SUBSONIC FILTER ADJUSTMENT
(PA1100.5 only)
This amplifier uses a subsonic filter to maximize the perfor-
mance of a subwoofer. The subsonic filter is a high-pass
filter that removes unwanted bass output at very low
frequencies form the woofer. This increases the output
of a subwoofer by as much as 3 dB by increasing the
mechanical power handling of the subwoofer. Depending
on the type of enclosure the subsonic filter can increase
the useable low frequency output by an additional 10dB!
Acceptable boost levels are determined by the type
of enclosure used, wattage of the amplifier, and the
subwoofer's excursion capability.
The following guidelines should be used for proper set
up of the subsonic filter to provide optimum performance
and reliability from your system.
