|
TRANSDUCERS |
|
|
Low Frequency |
Two 9‑inch long‑excursion cone drivers; 2 Ω nominal impedance |
|
High Frequency |
One 3‑inch diaphragm compression driver coupled to a constant‑directivity horn through a patented REM® manifold; 4 Ω nominal impedance |
|
AUDIO INPUT |
|
|
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 |
