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
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 output, DC blocked through signal processing
CMRR > 50 dB, typically 80 dB (50 Hz – 500 Hz)
RF lter Common mode: 425 kHz
Differential mode: 142 kHz
TIM lter <80 kHz, integral to signal processing
Nominal input sensitivity 0 dB V (1 V rms, 1.4 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
Amplier type Complementary power MOSFET output stages (class AB/H)
Output power 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 amplier 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.
THD, IM TIM < .02%
Load capacity 4 Ω low, mid and very high channels; 8 Ω high channel
Cooling Forced air cooling, 4 fans total (2 ultrahigh-speed reserve fans)
AC POWER
AC power connector 250 V AC NEMA L6-20 (twistlock) inlet, IEC 309 male inlet, or
VEAM all-in-one connector (integrates AC, audio and network)
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)
11.2 A rms (115 V AC), 5.6 A rms (230 V AC), 12.9 A rms (100 V AC)
Burst Current (<1 sec) 14.4 A rms (115 V AC), 7.2 A rms (230 V AC), 16.6 A rms (100 V AC)
Note: AC power cabling must be of sufcient gauge so that under burst current RMS conditions, cable transmission
losses do not drop voltage below specied operating range at the speaker.
Ultimate Short-Term Peak
Current Draw
32 A rms (115 V AC), 16 A rms (230 V AC), 37 A rms (100 V AC)
Inrush Current 7 A rms (115 and 110 V AC), 10 A rms (230 V AC)
RMS NETWORK
Equipped for two conductor twisted-pair network, reporting all operating parameters of
ampliers to system operator’s host computer.
