Acoustics
Operating bandwidth: 75 Hz - 20 kHz
Frequency response: 80 Hz - 16 kHz, within ±4 dB
Phase deviation: ±60° from 300 Hz to 18 kHz
Maximum peak SPL3: 123 dB
Dynamic range: >110 dB
Coverage
Horizontal: 100

Transducers
Bass: Two 125 mm (5 inch) diameter woofers Nominal impedance: 8 Ω / Voice coil diameter: 25 mm / Maximum power handling: 200 W (AES)6
Treble : One metal dome tweeter, diameter 25 mm / Nominal impedance : 8 Ω Voice coil diameter : 25 mm Diaphragm diameter : 25 mm Maximum power handling : 20 W (AES)
Audio Input
Type : Differential stage, electronically balanced
Maximum common mode voltage : ±15 V cont., ground reference for protection against voltage peaks
Connectors: Input: XLR female, Output: XLR male (Loop)
Input impedance: 10 kΩ, differential between points 2 and 3
Wiring: Point 1: Chassis/ground via 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies / Point 2: Hot (+) point / Point 3: Cold (-) point (optional polarity reversal selector)7 Enclosure: Ground/earth and chassis
DC component filtering: Diff. comp. blocking, up to max. common mode voltage
Common Mode Rejection Ratio (CMRR): >50 dB, typically 80 dB (50 Hz to 500 Hz)
RF filter: Common mode: 425 kHz; differential mode: 142 kHz
TIM filter: <80 kHz, integrated into signal processing
Nominal Input Sensitivity: A continuous average value of 0 dBV (1 V rms / 1.4 V peak) typically activates the limiter, on pink noise and music
Input Level: The audio source must generate a minimum level of +20 dBV (i.e., 10 V rms / 14 V peak) into 600 Ω to produce the maximum sound pressure level in the speaker's operational bandwidth.
