360° single unit; varies for multiple units, depending on number and configuration
Transducers
Low Frequency, Two 15" cone drivers, Nominal impedance: 4Ω, Voice coil size: 3", Power-handling capability: 400 W
Audio Input
Type: Differential, electronically balanced
Maximum Common Mode Range: ±15 V DC, clamped to earth for voltage transient protection
Connectors: Female XLR input with male XLR loop output or VEAM all-in-one (integrates AC, audio and network)
Input Impedance: 10 kΩ differential between pins 2 & 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 - (optional polarity reversal switch)
Case: Earth ground and chassis
DC Blocking: Differential DC blocking up to max common mode voltage
CMRR: >50 dB, Typically 80 dB (50 Hz - 500 Hz)
RF Filter: Common Mode: 425 kHz; Differential Mode: 142 kHz
TIM Filter: <80 kHz, integral to signal processing
Nominal Input Sensitivity: 0 dBV (1 V rms, 1.4 V pk) continuous is typically the onset of limiting for pink noise and music
Input Level: Audio source must be capable of producing a minimum of +20 dBV (10 V rms, 14 V pk) into 600Ω in order to produce maximum peak SPL over the operating bandwidth of the loudspeaker
