TRANSDUCERS

Low Frequency

One 15-inch, dual-coil, long-excursion cone driver; 2 Ω nominal impedance

AUDIO I NPUT

Type

Differential, electronically balanced

Maximum Common Mode Range

±15 V DC, clamped to earth for voltage transient protection

Connectors

XLR 3-pin female with male loop. Optional 5-pin connectors 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 clamped network to provide virtual ground lift at audio frequencies

Pin 2: Signal (+) Pin 3: Signal (–) Pin 4: RMS

Pin 5: RMS

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 Level

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
