|
Connectors |
XLR 3‑pin female input with male loop output; optional 5‑pin connectors to accommodate both balanced audio and RMS signals |
|
Input Impedance |
10 kΩ differential between pins 2 and 3 |
|
Wiring |
Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies Pin 2: Signal + Pin 3: Signal ‑ 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. |
