Rotatable horn: 70° x 50°

TRANSDUCERS

Low Frequency

Two 8-inch cone drivers; 4 Ω nominal impedance

High Frequency

One 3-inch diaphragm compression driver connected to a rotatable horn; 8 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 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.
