700 W total (550 W low channel, 250 W high channel)
Note: Amplifier wattage rating based on the maximum unclipped burst sine-wave RMS volt-
age the amplifier will produce into the nominal load impedance: low-frequency channel, 33 V
rms into 2 ; high-frequency channel, 33 V rms into 8 .
1400 W peak
Note: Peak power output based on the maximum unclipped peak voltage the amplifier will
produce into the nominal load impedance: low-frequency channel, 46 V peak into 2 ; high-
frequency channel, 46 V peak into 8 .
<.02%
2 low channel, 8 high channel
Convection, with recessed heat sink
PowerCon with loop output
Automatic, continuous range from 90–265 V AC
100–240 V AC, 50/60 Hz
90 V AC on, no turn-off, only fuse-protect above 265 V AC
0.23 A rms (115 V AC); 0.19 A rms (230 V AC); 0.24 A rms (100 V AC)
1.58 A rms (115 V AC); 0.83 A rms (230 V AC); 1.78 A rms (100 V AC)
3.1 A peak (115 V AC); 1.4 A peak (230 V AC); 3.6 A peak (100 V AC)
Note: AC power cabling must be of sufficient gauge so that under burst current rms condi-
tions, cable transmission losses do not drop below the loudspeaker's specified operating volt-
age range.
