APPENDIX A: ACHERON 80 AND ACHERON 100 SPECIFICATIONS
36
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
AMPLIFIER
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)
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 0.71 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.
Ultimate Short-Term Peak Cur-
rent 26 A peak (115 V AC); 14 A peak (230 V AC); 28 A peak (100 V AC)
Inrush Current 7 A peak (115 V AC); 7 A peak (230 V AC); 10 A peak (100 V AC)
