8. Fine tune controls for desired effect.
9. THRESHOLD is interactive with the PREAMP
GAIN control; boost or cut the PREAMP GAIN
level if the THRESHOLD control becomes out
of range (swapping the equalizer before the
compressor may also necessitate re-adjusting
the threshold level).
4.4.3 Linking Two Vt-737sp’s
Two Vt-737sp’s can be linked for stereo opera-
tion. The compressor sections of both units are
linked and controlled by one set of controls. It
is important to make sure that the pair of
Vt-737sp’s that are being used together
have been calibrated to operate as a
matched pair. If you purchased both
Vt-737sp’s at the same mtime and the serial
numbers are consecutive then your units were
calibrated as a stereo pair at the Avalon facto-
ry. If you need to calibrate your two units as a
stereo pair, please call the Avalon factory.
To link two Vt-737sp’s simply plug a 1/4”
unbalanced shielded instrument cable into
each units’ LINK jack on rear of the unit. When
two units are linked, the compressors will com-
press the same. The unit with most aggressive
compression parameters is the master.
Set one unit’s compression
ratio to 1:1 and then use the
other unit (master) to set
the compression for both
units. With the meter
switched in to measure
gainreduction on both units
the VU meter needles will
move together.
4.4.4 Using the Equalizer
The equalizer section of the Vt-737sp has been
designed to be simple to operate and have
powerful control for musical creativity.
Engage EQ push-button (illuminates “IN”) to
insert the EQ in the signal path.
The knobs labeled BASS, LOW, MID, HIGH MID
and TREBLE vary the amount of cut or boost
(also referred to as level or amplitude) to the
frequency specified. The knobs directly below
the amplitude controls select the frequency to
be boosted or cut.
The TREBLE and BASS filter bands utilize pas-
sive equalization with fixed shelving points.
The passive equalization gives the TREBLE and
BASS EQ smooth and musical sounding EQ at
the endpoints of the frequency range.
The LOW MID and HIGH MID EQ controls
fuction in a similar fashion. The frequency
settings are active giving more “agressive” EQ
for the LOW MID and HIGH MID EQ controls.
The LOW MID and HIGH MID have switches
marked “X10” (read times ten).
