Determines the unit's MODE of operation. When this switch is disengaged, VSXII is configured as a two-
channel, 2-way, stereo crossover. When this switch is depressed, VSXII is configured as a single channel, 3-
way, mono crossover.

This yellow LED blinks (1Hz) continuously when the VSXII is in stereo mode. It also indicates the control
functions for this MODE are depicted on the upper white strip.

This yellow LED blinks (1 Hz) continuously when the VSXII is in mono mode. It also indicates the control
functions for this MODE are depicted on the lower white strip.
( ( 1 1 8 8 ) ) G G a a i i n n 2 2
Used to optimize the interface gain between the VSXII Channel 2, and the associated mixer. Control range is
-20 dB to +20 dB with Unity gain at center (detent) position. In mono MODE Gain 2 is not used.
( ( 1 1 9 9 ) ) L L o o w w C C u u t t F F i i l l t t e e r r ( ( L L C C F F 2 2 ) )
Provides a 24 dB per octave roll-off at 40 Hz to reduce subsonic rumble and to protect the low speaker from
operating below its cutoff frequency. Affects both, the Low and High frequency bands. When not engaged,
the low-end roll-off frequency of Channel 2 is below 10 Hz. In mono MODE this filter is not operable.
( ( 2 2 0 0 ) ) L L o o w w 2 2 P P o o l l a a r r i i t t y y S S w w i i t t c c h h
When engaged‚ reverses the polarity of the signal in the Low frequency band to speed up trouble shooting
and assure proper phase response of the audio system.

This green LED indicates the presence of a signal higher than -22 dBu in the LOW 2-band even if the
band is muted.
( ( 2 2 2 2 ) ) L L o o w w 2 2 M M u u t t e e S S w w i i t t c c h h
When engaged‚ eliminates the signal in the LOW 2 band, to help during installation of the audio system.
( ( 2 2 3 3 ) ) C C l l i i p p / / M M u u t t e e L L E E D D
This red LED indicates when the signal level in the LOW 2 frequency band is approaching the maximum
available headroom of +22 dBu. It illuminates when the band signal reaches approximately +20 dBu. In
Mute mode this LED illuminates continuously.

Each band-pass section features a level control to compensate for the various loudspeaker efficiency
ratings. The Low 2 Level has +/-20 dB range and unity gain (default) at the center detent position. In Mono
MODE, LOW 2 is the MID band level control.

The VSXII two outputs per channel are derived from a fourth-order, Linkwitz/Riley, state variable filter
(24 dB per octave slope). Each filter is independent, with the crossover frequency selected via a recessed
knob, rotary control, to prevent accidental changing of the critical crossover frequency. Control range is
from 60 Hz to 6 kHz and in stereo MODE determines the -6 dB crossover point between the low and high
frequency bands within channel 2. In mono MODE this control determines the crossover point between the
MID and HIGH frequency bands.
