Golden Age Project | PREQ-73

The PREQ-73 is a one-channel vintage style microphone - line - and instrument preamplifier with a two band shelving equalizer offering a smooth and effective sound shaping. The signal path uses only discrete components like resistors, capacitors and transistors. The line and microphone input and the line output are transformer balanced, using three different transformers, each one optimized for its purpose.



The fully floating output can drive a level of at least +26 dBu into a load as low as 600 Ohms.  

This is the way audio components were built before integrated circuits became available. 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.  

The circuit used in the PREQ-73 is similar to the preamp and part of the equalizer section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
