             Type Differential, electronically balanced 
            Maximum Common Mode Range ±15 V DC, clamped to earth for voltage transient protection 
            Connectors XLR 3-pin female input with XLR 3-pin male loop output 
            Input Impedance 10 kΩ differential between pins 2 and 3 
            Wiring Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamped network 
            to provide virtual ground lift at audio frequencies Pin 2: Signal + 
            Pin 3: Signal – 
            Case: Earth ground and chassis 
            DC Blocking Differential DC blocking up to the maximum common mode voltage 
            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 (1.0 V rms, 1.4 V peak) continuous is typically the onset of 
            limiting for noise and music 
            Input Level Audio source must be capable of producing +20 dBV (10 V rms, 
            14 V peak) into 600 Ω to produce the maximum peak SPL over the 
            operating bandwidth of the loudspeaker
