The dbx 1066 is a professional dual-channel dynamics processor that combines a compressor/limiter and a noise gate on each channel within a single rack unit, offering comprehensive signal control for recording, broadcasting, and live sound. Each channel operates independently, providing a full complement of controls for threshold, ratio, attack, release, and output gain on the compressor/limiter section, along with separate threshold, range, attack, and release controls for the gate. The compressor is known for its musical OverEasy® soft-knee characteristic, which provides a smooth, gradual onset of gain reduction, making it well-suited for transparently controlling levels on vocals, bass, drums, and program material without introducing audible pumping artifacts.

A distinctive feature of the 1066 is its integrated peak limiter following the compressor, acting as a final safety clamp to prevent transient overloads. The noise gate is effective at cleaning up background noise during silent passages, with a variable range control allowing it to function as a subtle noise reducer or a hard gate. The unit includes comprehensive metering via dual LED bar graphs that display both gain reduction from the dynamics processing and output level, providing clear visual feedback. With balanced XLR and 1/4" TRS inputs and outputs, the 1066 integrates easily into any professional signal chain. Its robust steel chassis and reliable analog VCA-based design ensure consistent performance and durability for both studio and touring use.

The dbx 1066 has earned a reputation as a versatile and dependable workhorse. It provides a significant amount of control in a straightforward package, delivering the classic, assertive dbx sound that can add weight and punch to a mix. For engineers seeking a no-nonsense, effective tool for taming dynamics and reducing noise across two channels, the 1066 offers proven performance and sonic character that has made it a staple in many professional and project studios.
