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 81, 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 processor.
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 -10dBu setting.
CONFIGURATIONS
If you will be using a PCM 81 as your primary effects unit, and your
system includes a console with one or more auxiliary (effects)
sends, connect the PCM 81 as shown on the next page. In most
applications, it is preferable to connect the PCM 81 outputs to two
of the console's input channel strips, panned full left and right,
rather than to the effects returns. This allows the greatest
flexibility in routing and equalization.
In this configuration the console controls are used to set the
amount of effect heard—the PCM 81's MIX control should be set
for 100% wet. To assign a global MIX setting:
1. Press Control.
2. Press Up or Down until 1.x is displayed in the lower left of the
display and System is displayed on the upper line.
3. Turn SELECT until System Mix Mode is displayed on the upper
line. 1.1 will be displayed in the lower left.
4. Turn ADJUST until the lower line reads:
1.1 ✱Global
5. Press Load /✱ to show the current global setting of MIX; use
ADJUST to set it to 100% wet.
