Retro Doublewide 500-Series Tube Compressor - Used  From Retro

The Retro Doublewide is a tube compressor module designed from the ground up for the 500 series. It's authentic Retro compression for the masses. The Doublewide delivers the tube compression sound you expect because it has four actual variable-mu tubes under the hood.  While not precisely like any other tube compressor, the Doublewide methodology takes after the Sta-Level. As such, it excels at processing delicate sources like bass and vocals.  It's all Retro and is built with the same quality components in our U.S. shop alongside our other products.

The tubes and transformers in a fully complementary push-pull topology deliver sonic characteristics typical of a full sized tube compressor. The Doublewide incorporates four NOS 6BJ6 variable-mu tubes in two gain stages as well as two high-quality Cinemag transformers.  Input and output are fully floating and transformer balanced for use with line level signals.  A hard-wire bypass switch allows for quick evaluation of the compression signature.  Compression attack and recovery times are continuously variable.  Like the Sta-Level and 176, the Doublewide has two timing characteristic modes; Single and Double. Double mode provides a dynamic program-controlled attack and recovery timing.  With these two modes, the Doublewide is versatile in the studio, with full control of weight and punch versus transparency.

The Doublewide is designed to provide the user with years of reliable service.  Special circuitry eliminates excess current inrush and component stress when power is applied.  Power required is 180 milliamps (6 watts), which is well within a two-slot power allowance.  The tubes are self-biased and balanced without the need for user adjustments and there are no internal controls.  A meter-zero adjustment is accessible from the side of the unit to compensate for tube variations.  Tube replacement is straightforward and the tubes are readily available.
