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, attack and release settings, and the gain reduction
Crosstalk > 70 dB, 40 Hz ... 15 kHz
Dynamic Range / Noise
RMS 22Hz-22kHz <= -92 dBu no Regulation at 0 dB Gain
total Dynamic Range referring to the RMS Value 22Hz-22kHz
>= 122 dB no Regulation at 0 dB Gain
Control Voltage
> 70 dB
Limiter very fast Peak Limiter
Threshold Control Range + 20 dB to - 10 dB, referring to + 6 dBu
0 dB Setting internally calibrated
fine control with center click and +/- 2 dB range
LF-Attack Increases the attack time for low frequencies up to 120 Hz to smooth hard edges with audible attack distortion with fast static attack times. The setting of the pot determines the frequency.
Attack Attack Time Adjustment for 10 dB Attenuation
Control Range 0.02 ms to 7 ms
(with short attack time, the period of the input signal determines the real attack time)
Release Release Time Adjustment for 10 dB Gain Change
Control Range 50 ms to 3 s
Dynamic Release Increases the static release time depending on the density of the signal.
Gain Output gain post limiter with calibrated center detent
and +/- 10 dB range
Options half or twice the Static Release time range by jumper
half or twice the Dynamic Release time Rane by jumper
Release Law dB-linear over 3 dB range and very fast above 3 dB instead of dB-linear by independent jumpers for
static and dynamic release
Gain switch with bypass or constant on by jumper
Display Gain reduction display with 5 LED's,
display range from 1 dB to 10 dB
Bypass Circuitry Hardbypass by Relay
*) 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.
