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

 

 

Amplifier 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

 

amplifier will produce into the nominal load impedance — both channels 67 V rms (95 V pk).
