Product Specifications

INPUTS

• Power:
  • 35 W 230 V AC nominal, 45-65 Hz [120 V option available]
  • Power switch and LED indicator on front panel
• Microphone input:
  • XLR balanced microphone input for 200-600 Ω microphones;
  • 15 dB user selectable gain boost; + 15 V DC phantom power (selectable); sensitivity – 70 dBu; front panel recessed gain control
• Line input: 6.4 mm jack socket balanced line input; sensitivity – 30 dBu; overload protected; front panel recessed gain control
• Slave I/O:
  • 6.4 mm jack insert point for connection of SP5 phase shifter
  • 0 dBu signal can be used for recording

OUTPUTS

• Drive voltage: 8.5 Vrms (12V peak) at maximum output current
• Drive current
  • 3.5 Arms (5 Apk) continuous 1 kHz sine wave
  • Short term peaks >7 Apk
  • Front panel recessed control
  • Drive current indicated on 4-LED display in 3 dB increments
• Loop connector: Wieland ST17/2 (supplied)
• Loop Monitor: Provides access to actual audio signal in loop via a 3.5 mm stereo headphone connector on front panel

AUDIO SYSTEM

• Freq. response: 80 Hz to 6.5 kHz
• Distortion: THD+N
• Automatic Gain Control:
  • The AGC is optimised for speech. Range >36 dBu
  • Front panel recessed input level control
• Metal loss correction: Corrects system frequency response due to metal structures in a building. Gain constant at 1 kHz, adjustable gain slope from 0 to 3 dB per octave
• This does not compensate for signal loss from metal structures, which can be significant

ADDITIONAL FUNCTIONS

• Fault Monitoring:
  • Three LED fault indicators on the front panel:
    • Overload – delivering over the rated current
    • Overheat – unit is too hot (mutes output signal)
    • Loop error – short circuit / open circuit error
• Ancillary:
  • To supply Ampetronic ancillary units
  • ±15 V DC 0.15 A power outlet on rear panel
• Cooling: Cooling is by natural convection from product casing
