Type
|
Differential, electronically balanced
|
|
Maximum Common Mode Range
|
±15 V DC, clamped to earth for voltage transient protection
|
|
Connectors
|
XLR 5‑pin female input with male loop output; XLR 3‑pin female connectors available to accommodate only balanced audio (no RMS signals)
|
|
Input Impedance
|
10 kΩ differential between pins 2 and 3
|
|
Wiring4
|
Pin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamped 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
|
6.0 dBV (2.0 V rms) continuous is typically the onset of limiting for noise and music
|
|
Input Levels
|
Audio source must be capable of producing +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker
