1U rack-mounted version of the SSL G Series console master bus compressor

This is the 1U rack mounting version of the SSL G Series console master bus compressor. It utilises the classic SSL G Series centre compressor design elements within a SuperAnalogue design topology. This brings the dual benefits of spectacular audio performance with a universally acclaimed compressor characteristic.

The Evolution of a Classic

  • The SL 4000 console was the first console to incorporate dynamics processing in every channel and a master compressor in the console centre section.
  • The ability to 'patch' into the SL 4000's centre compressor, and also control its side chain from an internal sub-mix, allowed engineers to discover the amazing unique qualities of this compressor for use on instruments like piano and drums, as well as its classic mix finalising capabilities. This versatility created the demand for a rack mount equivalent and a legendary piece of outboard gear was born.
  • The XLogic G Series Compressor is the latest version of the compressor and it uses the same classic twin VCA design as its console counterpart. Combined with improved input and output circuitry, this new unit provides improved audio performance, while retaining the dynamics characteristics that have provided numerous hit mixes for the world's best audio engineers.

The Sound of Success

The Solid State Logic SL 4000 G Series is the world's most successful studio production console. Its reputation is built upon SSL's design excellence, advanced electronic engineering and a sound quality that has produced hundreds of best selling recordings.

A key element in the sound of many of these recordings is punch and drive of the mixes created by the classic G-Series centre section compressor.

Common Mode Rejection Ratio (CMRR)
Input level +20dBu, ground referenced.
20Hz to 10kHz> 50dB
THD + Noise
Gain +0dB, input level +4dBu. Compressor switched out.
20Hz to 20kHz (80kHz filter)< 0.008%, typically 0.005%
Gain +0dB, input level +20dBu. Compressor switched out.
20Hz to 20kHz (80kHz filter)< 0.01%, typically <0.006%
THD with the compressor switched in is dependent on attack and release times and signal content.
Apply +20dBu test tone to either channel input with the other input terminated with 50 ohms. Crosstalk is the ratio of level at the output of the test channel and the output of the channel to which the signal is applied.
Crosstalk @ 50Hz< –110dB
Crosstalk @ 1kHz< –100dB

Output Impedance< 50 ohms
"Most studio engineers look upon the SSL console mix-buss compressor as an essential tool of the trade, and having access to one in a stand-alone box, with the added sonic benefits of the SSL's Superanalogue topology, is a masterstroke" - SOS Magazine 2006
