POLARITY SWITCH (7)
Provides either 0 degrees or 180 degrees sub woofer polarity
This switch is used on conjunction with the Crossover Frequency Control (9) to provide for the best match
between the Subwoofer output and the satellite speaker output in the crossover region.
GROUND LIFT SWITCH (8)
Provided for lifting cable shield from chassis ground, to break potential ground loops and reduce hum.
CROSSOVER FREQUENCY CONTROL (9)
Varies the crossover frequency between the Subwoofer and the High Pass Outputs sent to the satellite/s
speaker/s (11 & 12). 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 PVX Sub, a middle (12 o'clock) to
™
p
higher setting works best for most speakers.
KOSMOS C BASS ENHANCEMENT (10)
®
Provides the capability to add bass harmonics to enhance the perception of deep bass in the program material
without overloading the Subwoofer speaker.
This control is best used in moderation, and turning it full up can cause the program material to sound distorted
or unnatural.
HIGH PASS OUTPUTS (11 & 12)
These outputs provide a high-pass filtered signal to be fed to a full-range powered speaker system, such as the
PVXp 10, PVXp 12 or PVXp 15. 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 from each other, and their level is not
affected by the PVXp Sub Level control (6).
THRU FULL RANGE OUTPUT (13)
This output provides a full-range signal to be sent to any other device that requires a full-range signal, such as
another PVXp Sub, or some other line level audio device. This output is electronically buffered and isolated
from the input and from the other outputs.

CAUTIONS
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
The back plate can become hot to the touch. Do not block or cover the fan or the exhaust louvers from
ventilation. There must be a minimum of 4" of space behind the fan. Do not allow the airflow to be become
blocked by objects such as curtains or drapes, thermal building insulation, etc. It is recommended that the rear
of the PVXp Sub not be placed in a closed space or a space that has no fresh, cool airflow.
DO NOT connect the inputs of the PVXp Sub to the output of a power amplifier. The inputs are meant to be
driven from a line-level strength signal.
DO NOT remove the protective metal grilles.
WARNING! The PVXp Sub is very efficient and powerful! This sound system can permanently damage hearing!
Use extreme care setting the overall maximum volume!
