SETTING AUDIO LEVELS
The PCM 91, with both analog and digital input and output
connections, requires some attention to proper setting of signal
level.
Analog inputs are first gain-conditioned by the rear panel input
gain switch, and then by the front panel INPUT knob. Proper
setting of both the switch and knob are important for best
performance of the A/D converter.
Analog and the selected digital sources are selected in Control
mode (0.0 Audio Input Source). The selections are: 44.1, 48, Ext:
XLR and Ext: Coax.
