APPENDIX C: SPECIFICATIONS
40
AMPLIFIER
Type 3-channel, open-loop, class D
Total Output Power 3900 W peak
Note: Peak power based on the maximum unclipped voltage the amplifier will produce
into the nominal load impedance.
THD, IM, TIM < 0.02%
Cooling Convection
AC POWER
Connectors powerCON 20 input with loop output
Automatic Voltage Selection 90–265 V AC
Safety Agency Rated Voltage
Range
100–240 V AC, 50–60 Hz
Turn-on/off Points Turn-on: 90 V AC; Turn-off: none; internal fuse protection above 265 V AC
CURRENT DRAW
Idle 0.46 A rms (115 V AC) 0.35 A rms (230 V AC) 0.49 A rms (100 V AC)
Maximum Long-Term Continuous
(> 10 sec)
3.0 A rms (115 V AC) 1.5 A rms (230 V AC) 3.4 A rms (100 V AC)
Burst (< 1 sec) 4.4 A rms (115 V AC) 2.3 A rms (230 V AC) 5.5 A rms (100 V AC)
Note: AC power cabling must be of sufficient gauge so that under burst rms current con-
ditions, cable transmission losses do not cause the loudspeaker’s voltage to drop below
the specified operating range.
Maximum Instantaneous Peak 12.6 A peak (115 V AC) 6.3 A peak (230 V AC) 14.5 A peak (100 V AC)
Inrush < 20 A peak
RMS NETWORK
Equipped with two-conductor twisted-pair network, reporting all operating parameters of
amplifiers to system operator’s host computer.
