Vintage Style Tube Compressor / Leveler
COMP-2A
Congratulations on choosing the Golden Age Project COMP-2A Compressor / Leveler!
The COMP-2A is a one channel vintage style Compressor / Leveler using vacuum tubes in the signal and
side-chain path
. The input and output is transformer balanced, using two different transformers, each one
optimized for its purpose. This is the way audio components were built before transistors and 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-2A is based on a classic design that was originally produced in the early 1960s
and it was initially intended for broadcast applications. It uses an electro-luminescent panel and a photoelec-
tric cell to control gain. This gives it a unique, program dependent compression characteristic. In addition, the
all tube signal path and the transformers 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 attri-
butes 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-2A.
FEATURES
- Vintage style all tube signal path. The tubes are fitted with grounded shields.
- Transformer balanced input and output. Can drive almost any load, balanced or unbalanced.
- Golden Age Project’s version of the classic optical unit using a long life electroluminescent panel and two carefully matched Silonex NSL5910
photoresistors for T4B-style electro-optical gain control 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.
- Linear regulated low noise filament and high voltage power supply.
- 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.
- 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.
