Recording studios often use rackmount "vocal channels," namely a mic preamp, compressor, and EQ all in one unit as a front end for vocal recording.

The Diamond Compressor is Diamond's take on a guitar channel: a dynamics and tone shaping tool for live and studio use, with low-noise, ultra-linear signal buffering, smooth opto-based compression, and a versatile 'tilt' EQ that musically shifts overall frequency balance. All in a user-friendly 3-control package - just Comp, EQ and Volume.

Features:

• Vactrol opto-isolator variable resistance path as used in high-end studio compressors for smooth attack and decay characteristics while preserving initial signal transients
•  Premium audio components, including 2% polypropylene capacitors,1% metal film resistors and a pro audio grade opamp (Diamond's signal path opamp alone costs 8 to 10 times what the industry norm uses)
•  Post-compressor 'tilt' EQ provides a very musical tailoring of frequency response - seamlessly transition from a darker jazz voicing to a brighter jangle, with flat frequency response at the center detent position
• Double filtering stage in side chain to eliminate low frequency modulation while preserving fast compression response
• Dual AC capacitive coupling paths for improved transient response
• Bi-color LED provides visual indication of depth of compression
• True bypass signal path
• Battery or standard negative tip 9V DC adapter operation, can be powered from 9 to 18 V negative tip
