Low Frequency: Two high-power 15-inch cone drivers with neodymium magnets; 4 Ω nominal impedance

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
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: 10 dBV (3.2 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.
