Setting Analog and Digital Input Level

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 0.2 Dig In Lvl, and turn ADJUST to display 0%.

NOTE: If you are not running digital audio, controlled by External Clock, into the PCM 80, the digital audio input will be disabled or muted. Until there is valid digital audio input, select 0.0 External to enable the digital input level control. Until valid digital audio is connected, the Dig In Lvl control will remain muted.

4.Turn SELECT to 0.1 Analog In Lvl, and turn ADJUST to display 100%.

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.If you are running digital audio, turn SELECT back to 0.2 Dig In Lvl, and turn ADJUST to the desired level. You may want to back off the Analog In Lvl setting to prevent the analog/digital mix from overloading the effects proces- sor.

Setting Output Level

While still in Control mode, turn SELECT to 0.6 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 -10dBusetting.
