700-HP SPECIFICATIONS
ACOUSTICAL
Operating frequency range 28 Hz - 150 Hz
Note: Recommended maximum operating frequency range. Response depends upon
loading conditions and room acoustics.
Frequency response 30 Hz - 125 Hz ±4 dB
Note: Free field, measured with 1/3 octave frequency resolution at 4 meters.
Phase response 45 Hz - 145 Hz ±30°
Maximum peak SPL 139 dB
Note:
Measured with music at 1 meter.
Dynamic range >110 dB
Coverage 360° (single unit); varies with number of units and configuration
TRANSDUCERS
Low frequency Two 18" cone drivers
Nominal impedance: 4
Ω
Voice coil size: 4"
Power-handling capability: 1200 W (AES)
Note:
Power handling is measured under AES standard conditions: transducer driven con-
tinuously for two hours with band limited noise signal having a 6 dB peak-average ratio.
AUDIO INPUT
Type Differential, electronically balanced
Max. common mode range ±15 V DC, clamped to earth for voltage transient protection
Connectors Female XLR input with male XLR loop output or VEAM all-in-one (integrates AC, audio &
network)
Input impedance 10 k
Ω
differential between pins 2 and 3
Wiring Pin 1: Chassis/earth through 220 k
Ω
, 1000 pF, 15 V clamp network to provide virtual
ground lift at audio frequencies
Pin 2:
Pin 3: Signal -
Case: Earth ground and chassis
DC Blocking None on input, DC blocked through signal processing
CMRR >50 dB, typically 80 dB (50 Hz – 500 Hz)
RF filter Common mode: 425 kHz; Differential mode: 142 kHz
TIM filter Integral to signal processing (<80 kHz)
Nominal input sensitivity 0 dBV (1 V rms, 1.4 V pk) continuous is typically the onset of 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.
AMPLIFIER
Amplifier type Two-channel complementary power MOSFET output stages (class AB/H)
Output power 2250 W (1125 W/channel)
Note: Amplifier 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) into 4 ohms.
THD, IM TIM < .02%
Load capacity 4 Ω each channel
Cooling Forced air cooling, two fans (one ultrahigh-speed reserve fan)
