EQ - Mid Q - 0 to 10 (.25-16)
This parameter is used to select the mid Q curve of the EQ. Selections are from 0 to 10, giv-
ing Qs of: .25, .5, .75, 1.0, 1.25, 2.0, 4.0, 8.0 and 16.0.
EQ - Mid Gain - -12 to 12
This parameter controls the Mid-gain output of the EQ section and ranges from -12 to +12dBu.
EQ - High Gain - -12 to 12 (+/-12dB @ 12kHz)
This parameter controls the High-gain output of the EQ section and ranges from -12 to +12dBu.
Compressor -Threshold - 1 to 60
Adjust this knob to set the threshold of compression from -40dBu (7.8mVrms) to +20dBu. Setting
the Compressor THRESHOLD at its highest level will prevent all but the highest level peaks from
being compressed. Setting the Compressor RATIO to 1:1 will turn the Compressor off, regard-
less of the setting of the Compressor THRESHOLD control.
Compressor - Ratio - 0 to 50 (1:1 - Inf:1)
Rotate this control clockwise to increase the amount of compression from 1:1 (no compres-
sion) up to ∞:1 (no increase in output level, regardless of input level increases above thresh-
old.)
Compressor - Gain - 0 to 20 (0-20dB)
This control is used to adjust the output gain of the Compressor module in 1dB increments.
Compressor -Attack - 1 to 99 (1-200ms)
The ATTACK control sets the amount of time it takes the ProVoca™l to begin compressing a sig-
nal (once the detector has sensed a signal above threshold). The ATTACK range is from 1 (FAST)
for a tighter and more noticeable compression effect with very little overshoot) to 99 (SLOW)

(for more delayed, gradual compression). A very fast ATTACK setting will cause the ProVocal™
to act like a peak limiter even though RMS detection circuitry is used. Slower ATTACK settings
cause the ProVocal™ to act like an RMS or averaging detecting compressor/limiter.
Compressor - Release - 1 to 99 (360-5dB/sec)
The RELEASE control sets how fast the compression circuit returns the input to its original level.
The RELEASE rate is from FAST (where compression follows the envelope of the program mate-
rial very tightly) to SLOW (for very smooth compression).There is no absolute right way to set
the ATTACK and RELEASE controls. However, in general, you will want them set slow enough
to avoid pumping or breathing sounds caused when background sounds are audibly modulat-
ed by the dominant signal energy, yet the release must be fast enough to avoid suppression of
the desired signal after a sudden transient or loud note has decayed.
Note: ATTACK and RELEASE controls operate together and in conjunction with the RATIO con-
trol. Changing one control may necessitate changing another setting.
De-Esser/Gate - De-Ess Frequency - 1 to 99 (800Hz-8kHz)
This parameter is used to set the frequency that the De-Esser module will process.
De-Esser/Gate - De-Ess Amount - 1 to 99
This parameter is used to set the overall sensitivity amount of the De-Esser module.
De-Esser/Gate - GateThreshold - 1 to 60 (-55dBu - +5dBu)
Adjusting the this control sets the level at which the gate will open and allow the signal at
the input to pass through to the output. Turning the knob fully counter clockwise (to off)
allows the gate to pass all signals unattenuated, effectively bypassing the gate. Turning the
knob fully clockwise causes the gate to attenuate input signals below +10dBu. The amount
of attenuation depends on the setting of the depth control.
De-Esser/Gate - Gate Ratio - 0 to 99
This parameter is used to control the amount that all signal below the threshold will be
reduced.
De-Esser/Gate - Gate Release - 1 to 99 (360-5dB/sec)
Adjusting the RELEASE control sets how fast the gate opens once the input signal rises above
the threshold. The release rate is from .01 seconds (fully counter clockwise) to 3 seconds (fully
clockwise).
Chorus/Flanger -Type - CH or FL
This parameter is used to select either the Chorus or Flanger effect.
Chorus/Flanger - Speed - 0-99
This parameter is used to set the speed of the Chorus or Flanger effect.
Chorus/Flanger - Depth - 0-99
This parameter is used to set the depth of the Chorus or Flanger effect.
Chorus/Flanger - Mix - 1-94
This parameter is used to set the amount of Chorus/Flanger effect that is mixed with the dry
signal.

Chorus/Flanger - CC - 1-10
This parameter is used to select the desired parameter to control with MIDI Settings are as fol-
lows: 1: Modeling Microphone, 2: Microphone Preamp Gain, 3: Compressor Gain,
4: Chorus/Flanger Speed, 5: Chorus/Flanger Depth, 6: Chorus/Flanger Mix, 7: Delay Time,
8: Delay Feedback, 9: Delay Input Level and 10: Reverb Mix/Decay.
Delay/Reverb - Delay time - 0-91 (0-1380ms)
This parameter is used to set the delay time of the Delay effect. Delay times range from 0-
1380ms, and are measured in 15ms increments.
Delay/Reverb - Delay Feedback - 0-95
This parameter is used to set the amount feedback in the Delay effect. The delay feedback is
measured in percentages (0-95%) and changes are made in 1% increments.
Delay/Reverb - Delay Mix - 0-99, 1
This parameter is used to set the amount of Delay effect that is mixed with the dry signal.
When set to all wet, no dry signal will be heard. In a typical multi-track recording situation,
the main vocal signal is recorded dry on to one track. This track will then be re-recorded on
to a second track will the delay set to all wet. During mix-down, the engineer can control the
blend of both tracks in real time.

The following information is provided to get you up and running with basic editing informa-
tion that will help you get the most out of your ProVocal™.
Making Connections
• Turn off all equipment before making any connections.
• Install the ProVocal™ in your rack with the provided rack screws. It is essential that when
the ProVocal™ is being mounted in a rack mounting enclosure, the unit should be positioned
with enough room (at least 1U of space above the unit and 1U of space below the unit) to
allow proper ventilation. The ProVocal™ should not be mounted above or below anything
that generates excessive heat. Ambient temperatures should not exceed 1130F (450C) when
equipment is in use. Although the unit is shielded against radio frequency and electromag-
netic interference, extremely high fields of RF and EMI should be avoided where possible.
• Make audio connections via XLR, 1/4” TRS, or 1/4” TS plugs (S/PDIF for digital output). With
the flexibility of the ProVocal™, various connection options are available. For input connec-
tion, use the XLR Microphone, 1/4” line or 1/4” instrument (front panel) inputs. For analog
