STEREO VOLTAGE CONTROL
PEAK LIMITER/COMPRESSOR MODEL 3722
All rights reserved. All features and specifications subject to change without notice
The Overstayer Stereo Voltage Control Model 3722 is a fluid integrated mixing signal
chain in a single rack space. It goes beyond the capabilities of a typical
compressor/limiter and enables new sonic possibilities while streamlining workflow.
It combines the gain control and punch of VCA gain cells, the warmth and character of
our discrete analog Harmonics circuitry, and the sculpting power of an ultra-smooth
2-band shelving EQ. The SVC has dynamics control from fast peak limiting to smooth
RMS compression, with multiple starting ratios and a Behavior control to create new
and unique envelopes. Use the LEVEL control to drive into Harmonics to further bend
peak transients, adding musical harmonic color and cohesiveness as well as increasing
apparent volume. The EQ and filters allow you to shape and drive as much low warmth
or smooth top presence as desired. Each of its multiple stages can add its character and
harmonics, cumulatively transforming the signal in a way not normally possible within
a single device.
The integrated blend control allows even aggressive settings to be balanced tastefully.
You can further create custom compression shaping by using the sidechain high-pass
filter for low end response, or even further by using the external sidechain insert.
FEATURES
●Highly interactive stereo dynamics, tone, and harmonics control

SAFETY AND INSTALLATION
Installation
1. Before attaching the DC plug of an adaptor to equipment, please unplug the adaptor
from the AC power and verify the unit is within the voltage and current rating on the
equipment.
2. Keep the linkage between the adaptor and its power cord tightly as well as connecting
the DC plug to equipment properly.
3. Protect the power cord from being trodden on or being squashed.
4. Use only an approved power cord, do not defeat the safety grounding pin which must
be connected to earth at all times (do not use a ground lift).
5. Keep good ventilation for the unit in use to prevent it from overheating. Do not install
near any heat source or device that produces heat.
6. An approved power cord should greater or equal to SVT, 3G×18AWG or H03VV-F,
3G×0.75mm2.
7. If the final equipment is not used for long period of time, disconnect the equipment
from power supply to avoid being damaged by voltage peaks or lightning strike.
Warning / Caution !!
1. Risk of electrical shock and energy hazard. All failure should be examined by a qualified
technician. Please do not remove the case of the adaptor by yourself!
2. Risk of fire or electrical shock. The openings should be protected from foreign objects
or dripping liquids.
3. Using wrong DC plug or forcing a DC plug into an electronic device may damage the
device or cause to malfunction.
4. Adaptors should be placed on a reliable surface. A drop or fall could cause damage.
5. Do not use or install in places with high moisture or near the water.
6. Do not use or install in places with high ambient temperature or near fire source.
7. Disconnect the unit from the AC power before cleaning. Do not use any liquid or
aerosol.
Please contact your local qualified recyclers when you want to dispose this product.

IN USE
To get to know the controls, its best to start with BEHAVIOR at 0 (things can get extreme with
this control at higher settings). The position of the LEVEL (harmonics) control is also critical, as
it sets how hard the circuitry is being driven. Getting to know where this starts to limit
transients and round peaks has a major impact on the sound of the unit, with and without the
HARMONICS button engaged. The tone and color can be very different depending on the
whether HARMONICS is in or out, and eq and low contour circuitry will also affect the
harmonics as they can have drastic impact on headroom and clipping points with large boosts.
The 3722 and analog gear in general have a bit of chaos in them, which is why we love them
and build them! Being a stereo unit, we trim for better than 1dB matching through a wide
range of settings, but deviations are inevitable in certain circumstances. Generally these are
more apparent visually on a meter than audibly.
CONNECTIONS

CONTROLS
EXT SC
Engages the external sidechain send and return loop. If no signal is present on the external
sidechain inputs, it will effectively bypass the compression. These connections are balanced.
Shape the compression response with the ability to insert complex eq and filters in the
sidechain.
SC FILTER
Engages a 220Hz high pass filter (6dB) in the sidechain path to even out the response of the
detector and allow bass frequencies and fundamentals to pass.
RATIOx2
Doubles the ratio from 2:1 soft knee (button out) to 4:1 medium knee when this button is in.
LIMIT
When pressed in conjunction with RATIO X2, sets a ratio of ~10:1.
FOR LIMIT TO BE ACTIVE, RATIOx2 MUST ALSO BE PRESSED
All rights reserved. All features and specifications subject to change without notice
The ratio settings given are based on a BEHAVIOR setting of ‘0’, increasing BEHAVIOR will result
in higher compression ratios. Each ratio has a different knee.
THRESHOLD
Sets the level at which compression occurs.
BEHAVIOR
Magnifies the compression envelope in a unique fashion. BEHAVIOR control manipulates the
hardness and envelope of the compression and can take the sound from virtually all ambience
to all transients. As this control interacts with the other compression controls, it creates a large
array of envelope shaping and sonic possibilities depending on the selected ratio and
attack/release settings. Start with this control at ‘0’ and ease it up to get a feel for what it does.
It can create very extreme compression at high settings, as it skews not only ratio but timing
(fast can get very fast, etc.)
ATTACK
Continuously variable ATTACK from 0.1 msec. to ~50 msec (with BEHAVIOR at 0). Pulling the
Attack control engages RMS mode (Attack and Release controls are inactive in RMS).
RELEASE
Continuously variable RELEASE from less than 0.1 sec. to ~1.1 sec. Pulling the Release control
engages a dual stage auto release. In this mode the control remains active, controlling the
time of the fast release stage, while a slower release reacts to the overall program level.
LEVEL
Controls the makeup level of the compression INTO the harmonics chain, setting the amount
of harmonic color. Unity setting is ‘0’. This control can be driven hard with or without
HARMONICS engaged for different textures and character.
LF BOOST
100Hz stereo shelving eq.
HF BOOST
12Khz shelving eq.
BLEND
Sets the balance between compressed and uncompressed signals.
OUTPUT
Sets the final output level, post blend. Unity setting is ‘6’.
LOW CONTOUR
All rights reserved. All features and specifications subject to change without notice
Engages a fixed high pass filter set at 50Hz with a resonant peak. Low Contour is relay
bypassed and completely out of the signal path when disengaged.
EQ IN
Engages the EQ circuitry. EQ is also relay bypassed and completely out of the signal path when
disengaged.
HARMONIC
Engages additional analog harmonics bus, driven with the LEVEL control (and eq). The
harmonics circuit softens and bends peaks and levels, as well as creating low order harmonics.
It has a wide range (sweet spot) before if hard clips, and can be used for subtle thickening and
inflating. Experimenting with transients, it will round before obvious clipping is heard, and will
increase apparent volume. It will also ‘push back’ a bit when eqing into it, and can add
cohesiveness. The HARMONIC circuit increases the gain to counter the limiting action, but at
high levels the limiting action of the circuit can actually lower the level relative to the
HARMONIC circuit disengaged.
ENGAGE
Relay switched bypass.
