APPENDIX B
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
Amplier type Two-channel complementary MOSFET output stages (class AB/H)
Output power 2250 W total
Note: Wattage rating is based on the maximum unclipped burst sine-wave rms voltage the
amplier will produce into the nominal load impedance — both channels 67 V rms (95 V pk).
THD, IM TIM < .02%
Load capacity 4 Ω each channel
Cooling Forced air cooling, 2 fans total (1 ultrahigh-speed reserve fan)
AC POWER
AC power connector PowerCon or VEAM
Voltage selection Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety agency rated
