BSS DPR 504 80's - Very Dark Blue/Black

NOT a hired or toured item. I think it is in excellent condition for its age. This item is the top one of the 3x BSS DPR 504's in the picture.

The BSS DPR-504 is a 4 channel noise gate, noise gating has become one of the fundamental processes used on an ever-increasing range of audio signal types. BSS have applied extensive experience in practical dynamics processor design and usage to create the ideal tool in a quick-to-use format that also conserves precious rack space.

The DPR-504 thoughtfully provides a flexible parametric KEY FILTER on each channel to allow frequency conscious gating with absolute precision. Quick adjustment by ear, using the momentary KEY LISTEN switch, eliminates hair-trigger threshold settings with ease, and offers considerable scope for special effects. The unique, ‘floating window’ key level LED display gives the engineer a constant visual indication of signal level above and below threshold, invaluable for quick set-up and for spotting problems instantly during a show or mix session.

BSS DPR 504 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.
