Two 4‑inch diaphragm compression drivers coupled to a constant‑directivity horn through a patented REM manifold; 12 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

Input Impedance

10 kΩ differential between pins 2 and 3

Wiring

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

Case: Earth ground and chassis

Nominal Input Sensitivity

0 dBV (1 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
