DBX 166XS vocal processor

• Stereo or mono two-channel gating, compression, and limiting;
• Selectable OverEasy and Hard Knee compression modes;
• Expander/gate circuit with adjustable release time and a maximum threshold of +15 dBu;
• Ability to engage sidechain equalization with the Contour button;
• PeakStop® output limiter for maximum signal level protection;
• True RMS signal detection;
• Bypass mode for comparing processed and unprocessed signals for both channels – functional even during power loss;
• 10-segment gain reduction meter for both channels (up to 30 dB);
• Electronically balanced input and output jacks in two standards – Canon/XLR and ¼” TRS;
• Independent sidechain insert for controlling compression or gating with an external device or signal;
