Analog performance specifications are tested with the System Two audio measurement system by Audio Precision, using a 400-Hz
HPF and 20-kHz LPF in the RMS mode at f
= 1 kHz.
Reference level (0 dB) is specified as 2-V rms input on V
L[1:6] and V
IN
R[1:6] pins with PGA gain of –5.5 dB.
Unselected channel inputs are terminated to AGND with 0.33
