Nominal Input Sensitivity

10 dBV (3.2 V rms, 4.5 V peak) continuous is typically the onset of limiting for noise and music

Input Level

Audio source must be capable of producing +20 dBV (10 V rms, 14 V peak) into 600 

Ω to pro-

duce the maximum peak SPL over the operating bandwidth of the loudspeaker

Type

Complementary MOSFET output stages (class AB/H)

Output Power

1685 W total (1125 W low channel, 560 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, 67 V 
rms (95 V peak) into 4 ohms; high frequency channel, 67 V rms (95 V peak) into 8 ohms.

Total Output

3370 W peak

THD, IM TIM

<.02%

Load Capacity

4 

Ω low channel, 8 Ω high channel

Cooling

Forced air cooling, two internal fans (one ultra low-speed fan, one reserve fan)

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

Idle Current

0.71 A rms (115 V AC); 0.38 A rms (230 V AC); 0.79 A rms (100 V AC)

Maximum Long-Term Continu-
ous Current

5.8 A rms (115 V AC); 2.8 A rms (230 V AC); 6.3 A rms (100 V AC)

Burst Current

6.4 A rms (115 V AC); 3.2 A rms (230 V AC); 7.2 A rms (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.
