CROSSOVER Frequency Control (11)
Varies the crossover frequency between the Subwoofer and the High Pass Outputs sent to the satellite/s speaker/s
(14 & 15). Varies the electrical crossover frequency from 90 Hz to 180 Hz.
CAUTION! SETTING THIS CONTROL TOO LOW MAY ALLOW THE SATELLITE SPEAKER TO BE
OVERLOADED BY DEEP BASS!
Setting the control lower DOES NOT increase the deep bass output of the PVs 18 Sub, a middle range (9:30 to
2:30 clock face position) setting works best for most speakers.
POLARITY SWITCH (12)
Provides either Normal (0 degrees) or Reverse (180 degrees) sub woofer polarity. This switch is used in conjunc-
tion with the Crossover Frequency Control (11) to provide for the best match between the Subwoofer output and
the satellite speaker output in the crossover region.
BASS ENHANCE SWITCH (13)
Provides the capability to add extra punch to the bass to enhance the perception of deep bass in the program ma-
terial without overloading the Subwoofer speaker. Useful for DJ and EDM music genre’s, it may cause excessive
boom if used for vocals or acoustic instruments.
BASS ENHANCE LED (14)
Illuminates Orange when the Bass Enhance switch has been engaged.
HIGH PASS OUTPUTS (15 & 16)
These outputs provide a high-pass filtered signal to be fed to a full-range powered speaker system. Other full-
range powered speakers can be used, and full-range passive speakers can be used in conjunction with a suitable
power amp to drive them.
These outputs are electronically buffered and isolated from the input, and their level is controlled by the PVs 18
Sub GAIN control (7). Thus, once the gain relationship between the Sub and the satellite speaker system has
been established, the overall gain of the combined Sub and satellite system can be changed with the PVs 18 Sub
GAIN control (7).
THRU FULL RANGE OUTPUT (17)
This output provides a full-range signal to be sent to any other device that requires a full-range signal, such as
another PVs 18 Sub, or some other line level audio device. This output is paralleled with the input, and the gain
does not change with changes in the PVs 18 Sub GAIN control (7).
