Vintage Style Compressor / Leveler
COMP-3A
INTRODUCTION
Congratulations on choosing the Golden Age Project COMP-3A Compressor / Leveler!
The COMP-3A is a one channel vintage style Compressor / Leveler. The signal path uses only discrete compo-
nents like resistors, capacitors and transistors. The input and output is transformer balanced, using two dif-
ferent transformers, each one optimized for its purpose. This is the way audio components were built before
integrated circuits became available.
Integrated circuits are small and cheap and widely used in most modern designs. The drawback is that audio
components built with modern technology doesn´t always provide the best perceived sound quality or the type
of character that the modern user desires.
The subjective sound quality delivered by vintage equipment is often prefered over the one delivered by
modern units, a situation that is even more obvious now when music is recorded with clean-sounding digital
audio equipment.
This is the reason why so many vintage audio components are cloned and produced again and also why the
vintage originals are often very expensive on the second hand market.
The circuit used in the COMP-3A is based on a classic design that uses an electro-luminescent panel and a
photoelectric cell to control gain. This gives the COMP-3A a unique, program dependent compression charac-
teristics. In addition, the vintage style signal path adds a wonderful and musical character to the sound. The
ease of use with only two main controls makes it very simple to achieve the desired sound. These attributes
has made the original units a favourite of engineers and musicians worldwide.
This classic sound is now available at a very affordable price point with the COMP-3A.
FEATURES
- Vintage style electronics. No integrated circuits in the signal path.
- Transformer balanced input and output. Can drive almost any load - balanced or unbalanced.
- Selectable output transformer loading resistors by an internal jumper, will affect the high end frequency response.
- Uses a classic T4-style electro-optical attenuator to control gain with program dependent attack and release times.
- Very simple to operate with only two main controls, Gain and Peak Reduction.
- HF control can make the side-chain circuit more sensitive to mid and high frequency content.
- A big meter selectable to show gain reduction or output level at two different reference levels.
- Hardwire bypass switch for easy comparisons.
- XLR and TRS input and output jacks for flexible connections.
- Link jack and switch for connecting to another unit for stereo operation.
- All external controls located on the front panel.
- External power supply to avoid interaction with the audio circuits and transformers.
- Compact 2RU half rack format. Two units can be mounted with our 19-inch rack kit, the UNITE BIG.
- A solid build quality that will last many years of normal use.

CIRCUIT DESCRIPTION
The signal first enters a 20 dB
resistive pad and is then fed to the
input transformer. The pad can be
disconnected if the input sensitivity
needs to be increased by moving
the 50/30 switch to the 50-position.
The signal is then fed to the T4
attenuator and onwards to the Gain
potentiometer and also, through the Peak Reduction poten-
tiometer, to the side-chain section.
The output stage, using only six transistors and some
passive components, follows the Gain potentiometer and
the output transformer then sends the signal to the output
jacks.
The side-chain section uses five transistors and an auto-
transformer that drives the electro-luminescent panel in
the T4. The higher the voltage the more light is emitted
on the photocells, their resistance decreases as the light
intensity increases, thereby bringing the audio signal closer
to ground in a R1/R2 resistor attenuator resulting in a lower
signal level (the photocell is the “R2”).
Engaging the HF control increases the side-chain signal
level in the mid- and high frequencies which will increase
compression of frequencies above 1 kHz.
MODERN VERSUS OLD
It is true that there are some great IC´s available today that
achieves very low levels of static and dynamic distortion.
The simple circuits that the COMP-3A uses, and even more
so the transformers, cannot match the low distortion speci-
fications of modern IC´s.
It is the distortion components that imparts a sound char-
acter to the audio signal and, if the distortion components
are of the right type, this is a good thing since it makes the
recorded voice or instrument sound “better”, more musical,
more pleasing to the ear. This is one reason why vintage
style units are so popular today.
This is not to suggest that modern, transparent sounding
audio circuits is a bad thing, sometimes they are prefered
over colored ones. It´s all about taste and it depends on the
genre. For most modern music styles, color and character
is definitely a good thing.
And doesn´t it feel good to use audio components built
according to the old, minimalistic approach where one can
follow the signal from one discrete component to another?
USING THE COMP-3A
The best way to explore the possibilities of any compres-
sor and how different settings affects the sound of different
sound sources is to experiment. You can also find a lot of
information on the www helping you to understand how
compressors work and how to use them.
To get started with using the COMP-3A:
- Connect the cable from the power adaptor to the 24V
AC jack at the back of the unit. Power on the unit with the
switch on the front panel.
- Connect your audio source to one of the input jacks at the
back panel and one of the output jacks to the next unit in
the signal chain. Please note that the TRS and XLR jacks
are connected in parallel. Switch the 50/30 switch to 30
if you need to increase the input sensitivity. The standard
position is the 50 position.
- The GAIN control sets the output level. A normal setting
for an input signal of around + 4 dBu (=1,23V) would
be somewhere around 3-5 with no compression applied, ie
PEAK REDUCTION set fully CCW.
- Then turn PEAK REDUCTION CW until you get the desired
amount of compression, The output level will decrease as
compression increases, you can compensate for that by
increasing GAIN.
- The approximate amount of gain reduction can be
diplayed by selecting GR on the meter switch. The normal
reading is 0 VU with no compression applied. You can trim
this reading using the ZERO adjustment potentiometer that
is accessed through a hole in the front panel.
The output level can be displayed by selecting +4 or +10 on
the meter switch. The numbers corresponds to the refer-
ence level when the meter shows 0 VU. The +10 position is
useful for avoiding the meter needle hitting its end stop at
high output levels,
- You can easily check the effect of the processing in the
COMP-3A by using the BYPASS switch, the unit is com-
pletely removed from the signal path in the IN position.
- Setting the MOD/NORMAL in the MOD position decreases
the gain in the output stage by 24dB and the 50/30 switch
should then normally be set to the 50 position to compen-
sate for the lower output stage gain.
Having both these switches in the upwards position lowers
the noise level in the unit. It also lowers the threshold
where compression begins, thereby allowing for a greater
amount of overall compression.
- Turning the HF control CW will make the compressor
more sensitive to mid and high frequency content.
- Selecting LIMIT will change the I/O curve, resulting in a
higher compression when the unit compresses heavily. The
COMPRESS position is the standard mode.
- For stereo operation, the side-chain of two COMP-3A units
can be linked together through the LINK jack at the back
panel, using an unbalanced TRS cable. The MONO adjust-
ment potentiometer can be used to balance the units. Find
instructions of the procedure on our web site.
WARRANTY
The COMP-3A is built to last. But as in any electronic device,
components can break down.
There is a fuse located inside the unit. If the unit dies,
please check this fuse. If it has blown, replace it with a new
one. You can also try with another 24V AC adaptor if you
have one available.
If this doesn´t help, or if the unit has another problem, it will
need repair and you should then contact the reseller where
you bought the unit.
The warranty period is decided by the Distributor for your
country. The Distributor will support Golden Age Project
resellers and end users with repairs and spare parts.

I would like to thank you for chosing the COMP-3A!
I hope it will serve you well and that it will help you
in making many great sounding recordings.

Vintage character for modern ideas!
