Technical Specifications:
Line Input:
- Impedance 1MW each side, 2MW differential
- Sensitivity: 7mV to 2.6V rms (-40dBu to +10dBu)
- Balanced signal input on 6.3mm 3-pole jack socket
- Common mode rejection better than 50dB below 500Hz.
Slave Input:
- Impedance 33kW Sensitivity 1V rms, +2.2dBu
- 6.3mm 2-pole jack socket
Slave Output:
- Source Impedance 1kW Output level 1V rms +2.2dBu
- 6.3mm 2-pole jack socket
Loop Current:
- 9.6A Peak signal current into a SINGLE TURN LOOP.
- Metering of peak current via front panel LEDs with intervals of 3dB
Loop Resistance:
- Must be less than 2W but greater than 0.4W
Compression:
- Compression range 30dB before overload
- Front panel indication of compression level
- Efficiency: less than 0.25dB output change for 25dB input change
- Attack and Decay time constants optimized for speech
Frequency Response:
- 80 to 10kHz ± 1.5dB at low level, measured as loop current
- High frequency high signal level response is a dynamic variable and is a function of loop size, loop current, and signal content to insure no RFI generation
- Internal time constants are very short
