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
15 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 15 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 15 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 15 Sub GAIN control (7).
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 ventila-
tion. There must be a minimum of 12” 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 PVs 15
Sub not be placed in a closed space or a space that has no fresh, cool airflow.
DO NOT connect the inputs of the PVs 15 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 PVs 15 Sub is very efficient and powerful! This sound system can permanently damage hear-
ing! Use extreme care setting the overall maximum loudness!
The apparent sound level of the PVs 15 Sub can be deceiving due to its clear, clean sound output and lack of high
frequencies. The lack of distortion or obvious distress can make the sound level seem much lower than it actually
is. This system is capable of SPL in excess of 127 dB at 1 M from the speaker!
