AUDIO INPUT
- Type
- Differential, electronically balanced
- Maximum Common Mode Range
- ±5 V DC, clamped to earth for voltage transient protection
- Connectors
- XLR 3-pin female input with male loop output; optional XLR 5-pin connector to accommodate both balanced audio and RMS signals.
- Input Impedance
- 10 kΩ differential between pins 2 and 3
- Wiring
- Pin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies Pin 2: Signal + Pin 3: Signal – Pin 4: RMS (polarity insensitive) Pin 5: RMS (polarity insensitive) Case: Earth ground and chassis
- Nominal Input Sensitivity
- 0 dBV (1.0 V rms) continuous is typically the onset of limiting for noise and music
- Input Level
- Audio source must be capable of producing of +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker.
