• Wiring
  • Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp 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 max 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 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 of +20 dBV (10 V rms, 14 V pk) into 600Ω in order to produce maximum peak SPL over the operating bandwidth of the loudspeaker
