INTRODUCTION
The Vocal Management System (VMS) is a world first,
designed by Studiomaster & Court Acoustics, packing all
the studio grade equipment a vocalist needs into one
compact product. However, the complexity has been left
out as the VMS is extremely easy to use and will give your
voice the sound it deserves, every performance.
An all new mic preamp design, precision optical
compressor and noise gate, seven band graphic equaliser
will ensure studio quality sound. The DSP (digital signal
processor) provides six stunning vocal effects designed by
Studiomaster using 30 years of live sound experience.
READ THE USER GUIDE
Despite the sophisticated design the VMS is very easy to
use although to get the best from your new purchase, we
recommend you read this User Guide before getting down
to any serious work.

Controls & Features - Front Panel
1. Mic/Line input sockets:
Combination XLR and jack. Suitable for use with balanced low
impendance microphones or line level signals typically from
mixing consoles. For convenience there are two sockets fitted,
one on the front and one on the rear panel. Only connect one
microphone or signal at any time.
2. +48V LED:
Illuminates when phantom power is turned on - see rear panel
controls and features.
3. VOICE control:
A six position switch marked SOFT to LOUD that refers to your
average voice level. This switch adjusts the gain of the VMS to
give the best setting for your particular voice. See SETUP
section for more details.
4. BYPASS switch:
Pressing this allows you to hear your voice unprocessed for
comparison purposes. Note the LEDs associated with the gate,
compressor, graphic and DSP turn off and the BYPASS LED
illuminates giving a visual indication of status.
5. NOISE GATE status LEDs:
The noise gate automatically turns the microphone off when you
stop singing. This reduces the unwanted background noise the
microphone would otherwise pick up. The open and closed LEDs
give a visual indication of the noise gate status.

Although the VMS contains a number of highly sophisticated
signal processing circuits, it is very easy to setup and use. We
recommend whatever level of audio experience, you read the
following section to get the best from this product.
1 Connecting up and checking control settings:
- Connect a microphone to either front or rear panel
MIC socket.
- Connect the output to your mixer, sound system etc.
- Check the NOISE GATE switch on the rear panel is
in the off (out) position.
- Connect the A.C. power cord / mains lead and switch
on, noting that the blue POWER LED illuminates.
- Check the DSP is turned off, confirmed by adjacent
green LED not illuminated.
- Check the VMS is in BYPASS mode, confirmed by
the adjacent red LED illuminating.
2 Getting sound:
- Sing into the microphone and adjust the VOICE
switch until one or two yellow (marked 0dB, +5) LEDs
on the bargraph illuminate with the loud parts of your
voice.
- Adjust your mixer or sound system for a suitable
volume level.
3 Activate your VMS!
- Release the BYPASS switch. Now when you sing into
the microphone the gain reduction LEDs illuminate

confirming correct operation. Your voice will now
sound warmer and have a more consistent volume.
- Typically the yellow and green gain reduction
(marked 15, 10, 5dB) LEDs flash when singing
showing normal operation. However, by adjusting the
VOICE control more or less LEDs illuminate showing
more or less compression being applied.
Experimenting with this control will find the best setting
for your voice.
4 Graphics:
If required make subtle tonal adjustments using the
graphic equaliser. However, if you are happy with the
tonal sound of your voice leave the graphic controls in
the central position.
5 The noise gate:
- Set the THRESHOLD control (on the rear panel) to
the centre, NORMAL position and switch on (in
position).
Note the red gate closed LED illuminates and back
ground noise disappears. As soon as you start to sing
the green gate open LED illuminates and your voice is
allowed through the VMS.
- The THRESHOLD control can be adjusted, if
required, for sensitivity. If the gate turns on too early,
'clips' certain sounds or words, the THRESHOLD
control should be turned anti-clockwise (towards -
60dB) slowly to increase its sensitivity. If the gate
appears too sensitive and never seems to close, turn
the THRESHOLD control clockwise (towards -20dB) to
reduce sensitivity.

GENERAL
Always use a good quality microphone that is suitable for your
style of singing and that you like the sound of. Your dealer can
show you mics specially designed for the voice. The VMS can
use dynamic or condenser type microphones so there is a big
choice available. It's time well spent getting the right mic.
Learn good microphone technique and avoid the obvious pitfalls.
Singing too far away from the mic will give poor signal and more
background noise whilst too close will cause distortion and poor
clarity. Sing directly into the mic (not on the side) at a distance
that suits you and the microphone.
Finally, never blow into a mic to test it. Your mic is a precision
instrument designed for the delicate vocal sounds - a hurricane
will destroy that precision!
COMPRESSOR / LIMITER
The dynamics of this compressor are internally set to give
optimum results on the human voice making a complex
electronic device like this easy to use. The SETUP section
outlines how to adjust the VOICE control to give good results.
However, turning the VOICE control clockwise will increase the
gain and so drive the compressor harder. This will give a slightly
thicker vocal sound with less dynamics. Turning the VOICE
control anti-clockwise will result in less compression giving a
slightly more open sound.
Experimentation may reveal 'your' perfect sound.
GRAPHIC EQUALISER (EQ)
The first point to mention here is if you are happy with the sound,
leave the 7 controls in the centre (off) position. More
performances have been ruined by too much EQ than not
enough.
Before making any EQ adjustments first consider the sound
source. Am I to close/too far away from the mic? Is it the wrong
type of mic? Is the speaker system in the wrong position? It is
much better to solve tonal problems at source rather than try to
'fix' them with an equaliser.
The 125Hz frequency is useful for reducing handling and low
frequency background noise.
The 8kHz frequency, although outside the range of the human

HOW TO SOUND GREAT
HINTS & TIPS

voice, is helpful in reducing sibilance.
Try cutting (lowering) either control and listen to the difference.
NOISE GATE
This is a great device for cutting out unwanted background
sounds and instrument overspill during your performance.
In live applications its setting will always be a compromise due to
the environment the performance takes place in. If the
background noise (from stage monitors, drum kits, guitars etc) is
almost as loud as your voice, a noise gate is limited in what it
can do. With this in mind, try to avoid directing the microphone to
other loud sound sources.
Carefully adjust the threshold control so that it doesn't close on
quiet passages or between songs when talking.
DSP - Digital Signal Processor
You will find all six effects on the VMS sound great with both
male and female voices, the choice of which effect is your
preference.
The DSP LEVEL control adjusts the volume of the effect that will
be mixed with your original voice. Avoid adding too much of the
effect, especially reverb, as it can make the voice sound distant,
losing impact. Likewise, not enough effect can be too subtle for a
live performance leaving the voice sounding dry.
Make use of the foot switch socket to turn on and off the DSP
remotely between songs. Speaking between songs is far clearer
without any effects.
Vocal 1: a combination of reverb and delay developed by
Studiomaster and the choice of many professional performers
world wide.
Small & Large Reverb: good quality reverbs great for ballads.
ADT - automatic double tracking: A technique used in the 60s
which adds a small delay to the voice giving a thicker, more
powerful vocal.
CHORUS: A modern, subtle effect that works well with voices in
the upper range.
ECHO: a classic rock & roll delay with several repeats.
