The dbx 166 is a classic 2-channel dynamics processor combining a compressor, expander/gate, and peak limiter in a single rack-space unit. Core Features:

• Dual-Channel / Stereo Operation: Can process two independent mono signals or be linked in a stereo couple mode where Channel 1 acts as the master controller for both channels using true RMS power summing.
• Expander / Gate Section: Features threshold and release controls (with fast/slow or program-adaptive timing) to cut out background noise and clean up signals like vocals or drums without abruptly clipping decay tails.
• PeakStop Limiter: Sets a ceiling on peak levels (ranging up to +21 dBv) to prevent digital/analog clipping and speaker or equipment damage.
• Sidechain Insert / Input: Dedicated rear-panel sidechain jack allows for frequency-conscious compression (such as de-essing), ducking, or external keying of the expander/gate.

Compressor Section:

• OverEasy®: OverEasy compression curve
• Controls: Threshold, ratio (from 1:1 up to ∞:1), peak level stop, and gate
• Classic dbx "Auto" Mode: Automatically adjusts attack and release times to match the program material.

Metering & I/O:

Precision multi-segment LED displays for real-time monitoring of gain reduction, compression threshold, and gate threshold.

Balanced inputs and outputs on 1/4" TRS connectors
