The 4 channel noise gate shall provide four channels of audio noise gating which can be used independantly or as two stereo pairs.
Each channel shall have separate side chain key parametric filters, switchable selection between fast or program dependant (Auto) attack modes and fully variable combined hold and release timing functions. Each gate shall have switchable attenuation range, key level peak and average responding LED display and independant gate open marker LED. There shall be selectable modes for internal or external key source, switchable key listen, stereo linking and a system IN
to show external key source selection, system IN status, and stereo link master/slave designation. Inputs and outputs shall be electronically balanced via 3-pin XLR-type connectors, with external key insert/input on 1/4″ TRS jack.
The noise gate shall be capable of operating at full line level up to +20dBv, with a frequency response 20Hz to 20kHz +/-1dB. Output noise shall always be less than -86dBv CCIR468-2, and harmonic distortion shall be less than 0.05%. The noise gate shall be capable of operating from a mains supply of 96-132V or 192-260V AC 50/60Hz. The noise gate shall be standard 19″ rack mount 1U (1ž ») high. The noise gate shall be the BSS DPR-504
