With +30 dB Boost on, 1.0 Vrms with Boost off
Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 KHz bandwidth.
(AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
± 1dB limits for Line Output & 0dB gain
Ratio of Full Scale signal to THD+N output with -3dB signal, measured “A weighted” over a 20 KHz BW, 48 KHz Sample

± 0.25dB limits
Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
