"This unit is in excellent condition and full working order. The Drawmer 1969 MERCENARY EDITION Mic Preamp/Tube Compressor. Versatile dual tube compression with Instrument, Mic and Line modes, based on the original 1960 ideal for use in both tracking and stereo compression applications. The Drawmer 1969 MERCENARY EDITION is a new product that derives from a collaboration between two of the audio industrys most established names, Drawmer (UK) and Mercenary Audio (USA). When Ivor Drawmer rose to the challenge of outspoken US producer/engineer Fletcher of Mercenary Audio to build a special version of the famed Drawmer 1960 (used by Eric Clapton, Madonna, Sheryl Crow, Stevie Wonder, Bryan Adams and thousands of artists around the world) - both sides joined forces and the 1969 Mercenary Edition was born. Based on Drawmers original 1960 Mic Pre-Amp/Tube Compressor (itself inspired by the classic Fairchild 670), the 1969 offers a host of new features, and more impressively - a completely new sound. Retaining the concept of twin mic pre-amps, the 1969 uses Burr-Brown op amps for a silkier sound - and a Phase Reverse switch available in Instrument, Mic and Line modes increases versatility. The 1969 employs true Stereo Link operation with channel ones Threshold, Attack and Release controls becoming master to both channels. Stereo Link also offers a BIG position which retains bass frequencies by rolling off the detection signal at 100Hz minimizing undesirable pumping during compression. Output Gain make-up can be independently controlled on each channel. The 1969 Mercenary Edition incorporates new tube circuits designed to add warmth to mic/line signals, and the instrument (DI) pre-amp has its own tube stage enabling classic overdrive effects when inserting guitar, bass and other instruments - true to the original Drawmer 1960 design. Where the original 1960 is known for its raunchy, British sound, the 1969 reflects the cleaner and brighter qualities one could associate with the classic American sound. Its just a question of taste. The main features of the Drawmer 1969 MERCENARY EDITION include: Versatile dual tube compression with Instrument, Mic and Line modes, based on the original 1960 ideal for use in both tracking and stereo compression applications 2 mic/line pre-amps with variable gain, 48V phantom power, filters and phase reverse Instrument tube pre-amp with variable gain, EQ, phase reverse and brightness boost 2 soft-knee tube compressors with variable threshold, attack, release and output gain True stereo link operation with BIG position for retaining bass frequencies Side chain access and side chain listen facility VU metering of gain reduction and output levels Individual +4dB/-10dB inserts Balanced +4dB XLR input/output connectors"
