BSS DPR-504
code: 852.BSS.010.RAC
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.
