180 - 20k Hz (-6dB, full space)
90° horizontal X +20 to -30° vertical (50° total, adjustable mount provides for vertical plane adjustments. The horizontal
plane can be adjusted by altering mounting position on the low frequency enclosure before tightening bolts.
9 dB (400 to 16k Hz average)
8 (400 to 16k Hz average)
Mid frequency 135.5 dB SPL
Tri-amp mode: high frequency/very high frequency 138 dB SPL
Quad-amp mode: high frequency 138 dB SPL, very high frequency 135 dB SPL
Tri-amp mode: 8 ohms nominal, mid frequency and high/very high frequency
Quad-amp mode:8 ohms nominal, mid, high, and very high frequency
Mid frequency: 275 W
Tri-amp mode: high/very high frequency 155 W (calculated, sum of high and very high frequency individual ratings)
Quad-amp mode:high frequency 85 W, very high frequency 70 W
Mid frequency: 105 dB SPL
Tri-amp mode: high/very high frequency 110 dB SPL
Quad-amp mode:high frequency 110 dB SPL
very high frequency 110 dB SPL
Tri-amp mode: mid frequency 250 Hz or higher, high/very frequency 1.7 kHz, both 24 dB/octave
Quad-amp mode: mid frequency 250 Hz or higher, high frequency 1.7 kHz, very high frequency 6.0 kHz, all 24 dB/octave
High frequency to very high frequency crossover at 7 kHz, 12 dB per octave, only in tri-amp mode. Quad-amp mode
switch setting removes crossover circuit from signal path, but leaves DC blocking capacitors in circuit.
Mid frequency driver: barrier strip screw terminals on mid frequency driver accept up to #10 AWG stranded wire.
High frequency, very high frequency drivers: barrier strip screw terminals accept up to #10 AWG stranded wire
Tri-amp mode connect high frequency/very high frequency program only to VHF/HF INPUTS terminals
Quad-amp mode connect high frequency program to HF INPUTS terminals and connect very high frequency
program to VHF INPUTS terminals.
Mid frequency: 10" high efficiency mid-range, phase-ring loaded
High frequency: 1.5" exit, 3.5" voice coil polyester diaphragm coaxial compression driver
Very High frequency: 1.5" exit, 1.75" voice coil polyester diaphragm coaxial compression driver
Attaches to top of QSC's low frequency cinema enclosures using three 5/16"-18 x 3/4" long bolts (supplied on low fre-
quency enclosure)
