1075C Specifications (subject to change without notice)
Freq. Range
180 - 15k (-6dB, full space)
Nominal Coverage
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.
DI:
9 dB (400 to 16k Hertz average)
Q:
8 (400 to 16k Hertz average)
Max. Output:
[Tri-amp mode] Mid Freq. 135.5 dB SPL calculated peak, 1m, full space
[Tri-amp mode] High Freq. 133 dB SPL calculated peak, 1m, full space
[Bi-amp mode] 135.5 dB SPL calculated peak, 1m ,full space
Impedance:
[Bi-amp mode] 8 ohms nominal
Maximum Input Power
[Tri-amp mode] Mid Freq. 275 W (AES method, 2 hrs.)
[Tri-amp mode] High Freq. 80 W (AES method, 2 hrs.)
[Bi-amp mode] 250 W (IEC method, 8 hrs.)
Sensitivity
[Tri-amp mode] Mid Freq. 105 dB SPL, 1 watt, 1 meter
[Tri-amp mode] High Freq. 108 dB SPL, 1 watt, 1 meter
[Bi-amp mode] 105 dB SPL, 1 watt, 1 meter
Crossover Frequencies
[Tri-amp mode] 250 Hertz or higher, 24dB/octave and 1.7k Hertz, 24dB/octave
[Bi-amp mode] 250 Hertz or higher, 24dB/octave
Crossover Network
1.7k Hertz, 18 dB/octave electrical slope, HF driver power limiting circuit (never disrupts continuity). Swit-
chable operation between Bi-Amp and Tri-amp operation. Tri-amp setting removes crossover circuit from
signal, leaving power limiter and DC blocking capacitors.
Connectors
Barrier strip screw terminals accept up to #10 AWG (6mm
2
) stranded wire. Four terminals, two HF input
and two MF input (for Tri-amp mode operation).
Transducers
MF: 10" high efficiency midrange, phase-ring loaded.
HF: 1.5" (38mm) exit, 3" (76mm) voice coil, titanium diaphragm compression driver.
Mounting Hardware:
Attaches to top of the low frequency cabinet using three M8, 20mm long bolts.
Size
39” high x 30” wide x 20” deep (991 x 762 x 508mm)
Weight
