The COMP-3A is a one channel vintage style Compressor / Leveler. The signal path uses only discrete components like resistors, capacitors and transistors. 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 integrated circuits became available.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 characteristics. 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.

Key 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.
• Compact 2RU half rack format. Two units can be mounted with our 19-inch rack kit, the UNITE BIG.
• External power supply to avoid interaction with the audio circuits and transformers.
