Setting Input Levels
1. Press Control.
2. Press Up or Down until the leftmost digit in the lower lefthand corner of the
display is 0.
3. Turn SELECT to 0.0 Audio Input Source.
4. Turn ADJUST to select Analog: 48kHz or Analog: 44.1kHz.
5. Adjust the front panel INPUT knob so that program material level peaks
cause the headroom display to reach the top of the column without lighting
the overload indicators. An occasional large signal peak causing momentary
flashing of the overload indicator is acceptable in most instances, but should
be validated by listening to the actual result.
6. Turn ADJUST to select Dig:. The display will show any valid digital format
which is properly connected to the PCM 90 rear panel digital input.

Setting Analog Output Level

While still in Control mode, turn SELECT to 0.3 Output Level. The Output Level
parameter has two range positions. The appropriate position depends on the
level handling capability of the device connected to the analog outputs. Devices
capable of handling outputs with peak levels of 18dBu require setting Output
Level to the +4dBu setting. Devices which cannot handle peak levels greater
than +4dBu require the -10dBu setting.
