Technical Specifications:
Microphone Input:
- XLR, balanced, low noise
- 15V DC Phantom supply selectable
- Input Sensitivity better than -70dBu at high gain setting, 55dBu at low gain setting
- Overload level -20dBu
Line Input:
- 6.4 mm Jack socket, fully balanced (unbalanced with mono plug)
- Sensitivity: -30dBu, overload at +20dBu High Impedance Input
- Overload protected
Slave I/O:
- Insert point for connection of AMPETRONIC Phase Shifter, Preamps, etc.
- Can be used as output for recording purposes
- Signal level 1 V RMS (+2.7dBu)
Preamp Power:
- ±15 Volt DC for powering AMPETRONIC Microphone Preamplifiers and external processors
Metal Loss Corrector:
- This control permits correction of the system frequency response when losses occur due to metal in the building
- Loss adjustment is adjustable from 0 to 3 dB per octave using 1 kHz as constant gain frequency
- This does not compensate for the power loss caused by the metal
Compressor / AGC Control:
- 36 dB control
- Attack / decay constants optimized for speech signals
- Front panel indication in 6 /12 dB increments
Output Current:
- 5.0 Amp Peak, absolute peak current > 7 A into SINGLE TURN loop
- Metering via front panel PPM response metering in 2dB increments
Output Voltage:
- Greater than 10 V peak to enable good frequency response for larger inductive loops
- Metering via front panel PPM response metering, 2dB increments
- Patented Circuitry to prevent clipping, ensure full compliance with EMC regulations
Area Coverage:
- Nominal area of coverage is a rectangular loop 120 m² / 1300 ft²
- Where the aspect ratio is long and narrow consult handbook
- Where metal is present or the loop position is unusual the area of coverage may be reduced
Loop Resistance:
- Must be less than 1W, greater than 0.2W
Loop Condition Testing:
- When switched on loop resistance is tested
- A front panel LED indicates loop error
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
AC Power Input:
- 115 Volts AC, 50-60 Hz. or 230 Volts AC, 45 - 65 Hz
- 55 VA Max power consumption
DC Power Input:
- 12V DC or 24V DC is available on the ILD122DC model
- 55 VA Max power consumption
Cooling:
- The unit is designed to utilize the case as a heat radiator
Dimensions:
- Width: 215mm / 8.5 in
- Height: 44mm / 1.75 in
- Depth: 210mm / 8.2 in
- Rack mounting kit available, requires 1U space
- Unit is 1/2 rack width
- Wall mount option using WML-1U mounting hardware
Weight:
- 2.0 Kg / 4.5 Lbs
The AMPETRONIC ILD122 Induction Loop Driver carries a 5 year warranty.
