SKU: DBX166XS Category:

dbx 166xs Compressor / Limiter / Gate offers two channels of noise gating, OverEasy or classic hard knee compression and PeakStop limiting to give complete control of signal dynamics to studios, sound reinforcement companies, musiciams or anyone who needs quality processing. The 166xs operates in stereo or dual-mono modes, has true RMS power summing and features quality XLR and 1/4″ TRS inputs and outputs. It cuts no corners on visual feedback with gain reduction metering and easy-to-read backlit switches.


Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes

New gate timing algorithms ensure the smoothest release characteristics

Program-adaptive expander/gates

Great sounding dynamics control for any type of program material

Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup

Stereo or dual-mono operation

Balanced inputs and outputs on 1/4″ TRS and XLR connectors

Side Chain insert

Classic dbx “Auto” mode
