The DBX 162 is essentially a pair of 160 compressors linked for stereo operation. Adjustable ratio, threshold, output. Great for tracking and stereo mix, etc. Rich tone. Great on drums, vocals, bass, kick, snare, across the 2 mix or stereo mix buss. The DBX 162 is a Voltage Controlled Amplifier compressor that uses a transformerless, solid-state design that has endured for decades. The program-dependent compression, combined with multiple gain stage components, creates a sound that is uniquely its own. The controls are simple: Threshold (with lights indicating above and below threshold value); Compression ratio from 1:1 to Infinity:1; Output Gain from -20 to +20 db attenuation; and three meter settings for input, output, and gain change.
