Dual Master Buss Compressor


The stereo compressor is two mono compressor circuits with some
extras designed for mastering and buss compression duties. The power supply
has separate high voltage and heater regulation to minimize cross talk. There is
a dry signal additive knob as well as an output attenuator. All controls are precision
stepped switches. Fine gain trimmers are provided on the front panel for small stereo
gain differences over time due to tube wear. A big addition to the stereo, is a fast
VCA based limiter that is controlled with one threshold knob. Limiting is indicated
by two LED’s above the analog meters. The limiter is designed to not only limit peaks,
but to bring a mix together. A little extra cohesion without squeezing the
life out of the music. Just turn the knob for a little bit…
Want a pure tube and transformer audio path without the bells and whistles?
There is a switch for that. For those times when you don’t need the solid state
mixing and limiting features, you can simply switch them out of the audio path.
The passive output attenuator remains functional.
