The DPR-504 is a 4-channel noise gate.
Each channel features a parametric key
filter with key filter listening, simultaneous
key level and threshold metering with
average and peak metering, a gate status LED, a RELEASE/HOLD control (hold tracks
proportionally with release times), attack
switchable auto/fast (auto tracks signal
dynamics for optimum setting), link (links
two channels together), key source allows
external triggers. RANGE switch selects
between 70dB and 20dB gating depth to
provide alternative release profiles. Inputs
and outputs are electronically balanced.
