This green LED indicates the presence of a signal higher than -22 dBu in the LOW 1-band even if the band is
muted.
( ( 5 5 ) ) L L o o w w 1 1 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 LF1 band, to help during installation of the audio system.
( ( 6 6 ) ) 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 LF1 frequency band is approaching the maximum available
headroom of +22 dBu. It illuminates when the band signal reaches approximately +20dBu. 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 1 Level has +/-20 dB range and unity gain (default) at the center detent position. In Mono MODE, LOW
1 is the only LOW 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 determines the -6 dB crossover point between the low- and high-frequency bands within the channel. In
mono MODE this control determines the crossover point between the LOW and MID frequency bands.
( ( 9 9 ) ) H H i i g g h h 1 1 B B a a n n d d L L e e v v e e l l C C o o n n t t r r o o l l
Each band-pass section features a level control to compensate for the various loudspeaker efficiency ratings.
The HIGH 1 Level has +/-20 dB range and unity gain (default) at the center detent position. In Mono MODE,
HIGH 1 is not used.

Adjusts the amount of boost within the HF band to compensate for the frequency roll-off and lost of efficiency
with some compression drivers. The screwdriver shaft control provides a variable boost from 0 dB to +12 dB at
20 kHz, with first-order slope and excellent phase response.
( ( 1 1 1 1 ) ) H H i i g g h h 1 1 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 HIGH 1 frequency band to speed up trouble shooting
and assure proper phase response of the audio system.
( ( 1 1 2 2 ) ) S S i i g g n n a a l l P P r r e e s s e e n n t t L L E E D D
This green LED indicates the presence of a signal higher than -22 dBu in the HIGH 1-band even if the band is
muted.
( ( 1 1 3 3 ) ) H H i i g g h h 1 1 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 HIGH 1 band, to help during the install of the audio system.
( ( 1 1 4 4 ) ) 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 HIGH 1 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.
