Gain  0 dB +/- 0.3 dB at offenem Gate
Frequency Response
20 Hz - 50 kHz +/- 0.2 dB no Regulation
- see Diagram Frequency Response
Bandwidth < 10 Hz to > 150 kHz
Phase Response 20 Hz-20 kHz < +6/-10° linear setting
- see Diagram Phase Response
THD < + 28 dBu, 40 Hz ... 20 kHz, < 0.1 %,
maximum THD at + 30 dBu <1 %
no Regulation
THD under regulation is determined by the frequency, taack and release settings, and the gain reduction
Dynamic Range / Noise
RMS 22Hz-22kHz <= -91 dBu at offenem Gate
total Dynamic Range referring to the RMS Value 22Hz-22kHz
>= 121 dB with gate open
Control Voltage Feedthru > 70 dB
Threshold Control Range + 20 dB to - 40 dB, referring to + 6 dBu
Threshold Hysterese 'Gate zu' nach 'Gate auf' and 'Gate auf' nach 'Gate zu < 0.2 dB
Range Attenuation with Gate closed
Control Range from 0 dB (Gate Off) to
70 dB
Attack Attack time control
Control Range 0.01 ms to 20 ms
(with short attack time settings, the attack time is determined by the frequency of the key signal)
Release Release time control for 20 dB attenuation
Control Range 50 ms to 3 s
The release time start at the end of the hold time
Hold Hold time control
keeps the gate open when the input level drops below threshold .
Control Range 20 ms to 2 s
Key Insert electronically balanced insert input and output with identical specs as the audio inputs and outputs. Allows to include external processing devices into the control loop.
Activated by push-pull switch of the range control.
Side Chain Filters Wide range high-pass and low-pass filters in the noise gate side chain. Both filters have 12 dB/oct steepness.
Side Chain Low-Pass Control Range 40 Hz to 8 kHz
Side Chain High-Pass Control Range 15 kHz to 50 Hz
Side Chain Listen (SCL) Switches the input of the side chain to the output. Allows easy control of the filter adjustment as well as the control of external processing gear at the key input. Activated by the push-pull switch of the Range pot.

*) The standard supply current is the supply current under realitic operation conditions. If the outputs are loaded with the minium load resistors and the level is at + 30 dBu, the supply current increases by 30 mA per output. The standard supply current shuold be used to calculate the necessary power supply capacity of a system.
