DESCRIPTION

The Model 612 Expander/Noise Gate is a true dual channel expander
using downward expansion with a variable ratio (1.2:1 to 30:1), thus
allowing an infinite variety of dynamics control which are impossible
with a gate. High and Low pass filters on the KEY input allow
frequency selected gating. With high ratio, the Model 612 becomes the
world’s finest gate. It is also a ducker, allowing a KEY input to
lower the level of the primary audio input.
The heart of the
Expander/Gate is the Aphex VCA 1001 which will not click regardless of
attack or release time! Attack time as low as 4 microseconds
(wavefront dependent). Absolute stability prevents settings from
wandering.
XLR-type Servo-Balanced I/O means foolproof installing
with balanced or unbalanced systems.
