AUDIO INPUT |
|
Type |
Differential, electronically balanced |
Maximum Common Mode Range |
±15 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 |
Wiring5 |
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. |
