Vintage Style Compressor

The COMP-54 is a one-channel vintage style compressor. The signal path uses only discrete components like
resistors, capacitors and transistors. The input and output are transformer balanced and the unit also uses a
third interstage transformer.
This is the way audio components were built before integrated circuits became available. IC´s are small and
cheap and they are widely used in most modern designs. It is clear though that audio components built with
modern technology doesn´t always provide the best perceived sound quality or character that the modern
user desires.
On the contrary, the subjective sound quality delivered by vintage equipment is often prefered over the one
delivered by modern units. 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 class-A circuit used in the COMP-54 is similar to the one in the classic 2254 compressor that was designed
in 1969. It quickly became a legend due to it´s totally unique sound character that is warm, smooth,
sweet and musical.
These characteristics have been heard on countless recordings through the years and it is a versatile sound
that works very well on many sound sources and in many genres. The essence of this sound is now available
at a surprisingly low cost, making it available to nearly everyone.
