28 Hz - 160 Hz
Note: Recommended maximum operating frequency range. Response depends upon
loading conditions and room acoustics.
30 Hz - 140 Hz ±4 dB
Note: Free field, measured with 1/3 octave frequency resolution at 4 meters.
40 Hz to 100 Hz ±45°
138 dB
Note: Measured with music at 1 meter.
>110 dB
360°
Varies, depending on array length and configuration.
Two 15" cone drivers with neodymium magnets
Nominal impedance: 4 Ω
Voice coil size: 4"
Power-handling capability: 1200 W (AES)
Note: Power handling is measured under AES standard conditions: transducer driven
continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
Differential, electronically balanced
±15 V DC, clamped to earth for voltage transient protection
Female XLR input with male XLR loop output or VEAM all-in-one connector (integrates AC,
audio and network)
10 kΩ differential between pins 2 and 3
Pin 1: Chassis/earth through a 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
None on input; DC blocked through signal processing
>50 dB, typically 80 dB (50 Hz – 500 Hz)
Common mode: 425 kHz; Differential mode: 142 kHz
<80 kHz, integral to signal processing
0 dB V (1 V rms, 1.4 pk) continuous is typically the onset of limiting for pink noise and
music.
