APPENDIX B
AUDIO INPUT
Type Differential, electronically balanced
Max. 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 connector (integrates AC,
audio, and network)
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
DC Blocking None on input, DC blocked through signal processing
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 dB V (1 V rms, 1.4 V pk) continuous is typically the onset of TPL limiting for noise and
music.
Input level 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
AMPLIFIERS
Amplifier type Four-channel complementary MOSFET output stages (class AB/H)
Output power 3020 W (four channels; 2 x 950 W, 2 x 560 W); 6000 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. Peak power based on the maximum unclipped peak voltage that the amplifier
will produce for at least 100 milliseconds into the nominal load impedance.
THD, IM TIM < .02%
Load capacity 4 Ω low and mid; 8 Ω high channels
Cooling Forced air cooling, 4 fans total (2 ultrahigh-speed reserve fans)
AC POWER
AC power connector 250 V AC NEMA L6-20 twistlock, IEC-309 male, PowerCon, or VEAM
Voltage selection Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety agency rated
operating voltage
95 V AC – 125 V AC, 208 V AC - 235 V AC, 50/60 Hz
Turn on/turn off points 85 V AC - 134 V AC; 165 V AC - 264 V AC
Current Draw
Idle current 1.1 A rms (115 V AC), 0.55 A rms (230 V AC), 1.3 A rms (100 V AC)
Max. long-term continuous
current (>10 sec)
5.4 A rms (115 V AC); 2.7 A rms (230 V AC); 6.2 A rms (100 V AC)
Burst Current (<1 sec) 8.7 A rms (115 V AC), 4.3 A rms (230 V AC), 10.0 A rms (100 V AC)
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.
Ultimate Short-Term Peak
Current Draw
24.6 A rms (115 V AC), 12.3 A rms (230 V AC), 28.3 A rms (100 V AC)
Inrush Current 11 A rms (115 and 100 V AC), 15 A rms (230 V AC)
RMS NETWORK
Equipped with two-conductor twisted-pair network, reporting all operating parameters of
amplifiers to system operator’s host computer.
