Technical Specifications:
Microphone Input:
- Suitable for driving from 200-600 Ohm microphones
- Electronically balanced
- Phantom voltage +15V available (normally set to 0V)
- Input Sensitivity better than -65dBu, overload level -20dBu
Line Input:
- Impedance 1 MW each side, 2 MW differential
- Sensitivity: 7mV to 7Vrms (-40dBu to +20dBU)
- Balanced signal input on 6.3 mm 3-pole jack socket
- Common mode rejection better than 50dB below 500Hz
Slave Input:
- Impedance 33KW Sensitivity 1V rms, +2.2dBu 3-pole jack socket
Slave Output:
- Source Impedance 100W
- Output level 1V rms +2.2dBu 3-pole jack socket
Loop Current:
- 5 Amp Peak signal current into SINGLE TURN loop
- Metering via front panel LEDs
- These LEDs indicate the peak current with intervals of 3dB
Loop Resistance:
- Must be less than 1W, greater than 0.2W
Compression:
- Compression range 36dB before overload
- Front panel indication of compression level
- Efficiency: less than 0.25dB output change for 25dB input change
- Attack and Decay tie constants optimized for speech
Frequency Response:
- 80 Hz to 10KHz ± 1.5dB at low level, measured as loop current
- High frequency high signal level response is a dynamic variable and a function of loop size, loop current and signal content to ensure that no RFI generation takes place
- Internal time constants are very short
