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.

Differential, electronically balanced
±15 V DC, clamped to earth for voltage transient protection
Female XLR input with male XLR loop output or VEAM
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
None on output, 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 TPL limiting for noise and
music.
Audio source must be capable of producing a minimum of +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
Complementary power MOSFET output stages (class AB/H)
3935 W (four channels; 3 x 1125 W, 1 x 560 W)
Note: Wattage rating is based on the maximum unclipped burst sine-wave RMS voltage
that the amplifier will produce into the nominal load impedance: low/low-mid and very-high
channels 67 V rms (95 pk) into 4 ohms; mid-high channel 67 V rms (95 V pk) into 8 ohms.
< .02%
4 Ω low, mid and very high channels; 8 Ω high channel
Forced air cooling, 4 fans total (2 ultrahigh-speed reserve fans)
250 V AC NEMA L6-20 (twistlock) inlet, IEC 309 male inlet, or
VEAM all-in-one connector (integrates AC, audio and network)
Automatic, two ranges, each with high-low voltage tap (uninterrupted)
