Source Impedance | 50 Ohms, see Diagram Output Source Resistance vs Frequency |
||
Load Resistor | see Diagram maximum Output Level vs Load Resistor and maximum Output Level vs capacitive Load |
||
CMRR according to IEC | > 40 dB, see Diagram Output CMRR vs Frequency | ||
Gain | 0 dB +/- 0.3 dB Gain Control @ 0 dB, no Regulation Control Range > +/- 20 dB the Gain Control determines the output level post compressor |
||
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 |
||
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 Rejection |
> 70 dB | ||
Crosstalk | > 65 dB, 40 Hz ... 15 kHz | ||
Threshold | Control Range + 15 dB to - 32 dB, referring to + 6 dBu 0 dB Setting internally calibrated |
||
Ratio | Compression Ratio Control Range from 1 : 1 - (Compressor off) to 1 : 20, Quasi Limiter Operation |
||
Crest | affects the behaviour of the AC/DC converter Kippschalter mit 3 Stellungen Peak - Peak Mode with short Integration Time RMS - RMS Mode with long Integration Time M - Mean Value with medium Integration Time |
||
Attack | Attack Time Adjustment for 10 dB Attenuation Control Range 0.05 ms to 30 ms (with short attack time settings, the real attack time is depending on the period of the input signal, and the crest setting) |
||
Release | Release Time Adjustment for 10 dB Gain Change Control Range 50 ms to 3 s |
||
Soft (Knee) | Determines the transition from the unregulated level range below threshold to the regulated range above threshold. A setting of 0 dB causes a hard transition. The scale value of any different setting determines the dB range of the transition. - see Diagram Soft Knee |
||
Smooth | Parallel Compression, adds the uncompressed input signal to the compressed output. Max level - 4 dB. | ||
Envelope | The Envelope Control improves the low frequency THD behaviour with short release time settings. The control determines the sphere of action from 0 (off) to 120 Hz. | ||
Autogain | analog computation circuitry to correct the loss of gain, depending on the settings of threshold, ratio and attack. Operates with threshold settings below 0 dB. Autogain can be disabled by the push-pull switch of the ratio pot. |
||
Display | Gain reduction display with 5 LED's , display range from 1 dB to 20 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. | |||
