Max. long-term continuous
current (>10 sec)
Burst Current (<1 sec)
Note: AC power cabling must be of sufficient gauge so that under burst current RMS conditions, cable transmission
losses do not drop voltage below specified operating range at the speaker.

18
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 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
Differential DC blocking up to maximum common mode voltage
>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 V pk) continuous is typically the onset of limiting for noise and music.
Audio source must be capable of producing +20 dBV (10 V rms, 14 V pk) into 600 Ω in
order to produce maximum peak SPL over the operating bandwidth of the loudspeaker
Three-channel complementary MOSFET output stages (class AB/H)
1275 W (three channels; 2 x 500 W, 1 x 275 W); 2550 W peak
Note: Amplifier wattage rating based on the maximum unclipped burst sine-wave rms
voltage that the amplifier will produce for at least 0.5 seconds into the nominal load
impedance.
