The dbx 166XL is a two-channel compressor/gate/limiter that has become a standard in studios, live rigs and installed sound thanks to its versatility and excellent sonic performance. Where other compressor/gates swallow transients or cut off decay tails, the 166XL's engineering keeps compression and gating musical even with difficult material. Its attack and release controls deliver classic dbx compression at centre settings and everything from slow levelling to aggressive peak limiting across the full range, with an Auto mode that adapts timing to the program material automatically. The advanced gate circuitry uses program-dependent timing algorithms for ultra-smooth release, and dbx's precision VCA design gives an extra-wide threshold range for top gating performance. Hard knee or patented OverEasy compression curves are selectable, and full sidechain functionality opens up advanced applications like de-essing and ducking. Separate LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup, while stereo coupling with True RMS Power Summing preserves a rock-solid image even under heavy compression. Whether smoothing vocals, fattening drums or protecting PA systems in Kenya, the 166XL sets up musically the first time, every time.
