BSS DPR 402 DPR-402 Dynamics Processing Compressor, Peak Limiter, De-Esser

The BSS DPR-402 is a professional dual-channel dynamics processor that has earned a solid reputation in recording studios, broadcast facilities, and live sound systems. Known for its flexibility, reliable performance, and comprehensive control, the DPR-402 combines a fully adjustable compressor, peak limiter, and two different de-essing modes, making it a practical tool for a wide range of audio applications.

Each channel features an independent compressor with adjustable threshold, ratio, attack, release, and output gain. The wide range of available settings allows everything from gentle dynamic control to aggressive compression and limiting. An Auto mode provides program-dependent attack and release characteristics, automatically adapting the compressor’s response to the incoming material for smooth and consistent results.

One of the DPR-402’s strengths is its versatile de-essing section, offering both high-frequency and wideband processing. The HF de-essing mode selectively reduces problematic high frequencies while leaving the rest of the signal largely unaffected. Wideband de-essing, on the other hand, controls the entire signal when excessive high-frequency energy is detected. This makes the DPR-402 particularly useful for controlling vocal sibilance, harsh instruments, and problematic high-frequency transients.

A dedicated peak limiter provides additional protection against excessive signal levels and can operate alongside conventional compression or wideband de-essing. Comprehensive LED metering displays gain reduction, input and output levels, and dynamic activity, allowing engineers to monitor processing accurately.
