Output Power
2250 W total (1125 W low channels)
Note: Amplifier wattage rating based on the maximum unclipped peak voltage the amplifier
will produce into the nominal load impedance: low frequency channels, 67 V rms (95 V peak)
into 4 ohms.
Total Output
4500 W peak

Ω low channels
Cooling
Forced air cooling, two internal fans (one ultra low-speed fan, one reserve fan)
AC POWER
Connectors
250 V NEMA L6-20 (twistlock) inlet or IEC 309 male inlet
Voltage Selection
Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety Agency Rated Operating
Voltage
95–125 V AC; 208–235 V AC; 50/60 Hz
Turn On/Turn Off Points
85–134 V AC; 165–264 V AC
Current Draw
Idle Current
0.64 A rms (115 V AC); 0.32 A rms (230 V AC); 0.85 A rms (100 V AC)
Maximum Long-Term Continu-
ous Current
8.8 A rms (115 V AC); 4.4 A rms (230 V AC); 10.0 A rms (100 V AC)
Burst Current

tions, cable transmission losses do not drop below the loudspeaker’s specified operating volt-
age range.
