Description

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.

The Range switch selects between 7OdB and 2OdB gating depth to provide alternative release profiles.

The unit features electronically balanced inputs and outputs.
