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
