SETTING AUDIO LEVELS (continued)
Setting Input Levels
1. Press Control.
2. Press Up or Down until the left-most digit in the lower left-
hand 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 91 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.
CONFIGURATIONS
If you will be using a PCM 91 as your primary effects unit, and your
system includes a console with one or more auxiliary (effects)
sends, connect the PCM 91 as shown at the top of page 1-13. In
most applications, it is preferable to connect the PCM 91 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 91'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.
