APPENDIX B
Nominal input sensitivity 0 dBV (1 V rms, 1.4 V pk) continuous is typically the onset of TPL limiting for noise and
music.
Input level Audio source must be capable of producing a minimum of +20 dBV (10 V rms, 14 V pk)
into 600 ohms in order to produce maximum peak SPL over the operating bandwidth of the
loudspeaker.
AMPLIFIERS
Amplifier type
Two-channel complementary power MOSFET output stages (class AB/bridged)
Output power 500 W total
Note: Wattage rating is based on the maximum unclipped burst sine-wave rms voltage the
amplifier will produce into the nominal load impedance — low channel 30 V rms (42 V pk);
high channel 27 V rms (38 V pk)
THD, IM TIM < .02%
Load capacity 4 Ω low channel, 2 Ω high channel
Cooling Forced air cooling over amplifier heatsink
AC POWER
AC power connector
PowerCon with looping output
Voltage selection Automatic
Safety agency rated
operating voltage
100 V AC - 240 V AC; 50/60 Hz
Turn on/turn off points Continuous 90 V AC - 264 V AC; 50/60 Hz
Note: No automatic turn-off voltages. Voltages above 264 V AC are fuse protected but
may cause permanent damage to the power supply. Voltages below 90 V AC may result in
intermittent operation.
Current Draw
Note: Current draw for a single loudspeaker. Loop out not used.
Idle current
0.41 A rms (115 V AC); 0.33 A rms (230 V AC); 0.42 A rms (100 V AC)
Max. long-term continuous
current (>10 sec)
3.2 A rms (115 V AC); 1.6 A rms (230 V AC); 3.7 A rms (100 V AC)
Burst Current (<1 sec) 5.0 A rms (115 V AC); 2.5 A rms (230 V AC); 5.8 A rms (100 V AC)
Ultimate Short-Term Peak
Current Draw
17 A pk (115 V AC); 8.5 A pk (230 V AC); 20 A pk (100 V AC)
Inrush Current 15 A pk (115 V AC); 13 A pk (230 V AC); 15 A pk (100 V AC)
