0.5 Emphasis Bit
The Emphasis control allows you to explicitly set the emphasis "flag" in the digital
audio, or to pass along the incoming signal without changing its emphasis
coding. (The PCM 81 does not perform any emphasis or de-emphasis as part
of its signal processing. The AES input/output path will correctly pass either 15/
50 or CCITT emphasis.) The choices available with ADJUST are: Yes, No, and
Pass Thru.
0.6 Output Level
This control allows you to select the maximum output level at the PCM 81's
analog outputs. Use ADJUST to select +4 dBu, or –10 dBu.
Exercise care when switching this control, as a 14dB level change
instantly occurs when going from -10dBu to +4dBu.
Row 1
System
1.0 Edit Mode
The PCM 81 has been designed with a "plug and play" feature called Go mode.
In this mode, the most useful parameters of each effect are grouped together in
a single row which is available whenever you press Edit.
Each PCM 81 preset has a set of Go mode parameters which we've selected for
you. When shipped, the PCM 81 will power up in Go mode, with the first preset
(P0 0.0) loaded. Press Edit to display the first available parameter in the Soft
Row.
If you want access to the full parameter matrix for any effect, including the Soft
Row parameters, use ADJUST to select Pro mode. Now, when Edit is pressed,
you can select any parameter for adjustment, and customize any effect with your
own Soft Row assignments. For more information about the Soft Row, see
Editing an Effect later in this chapter.
1.1 Mix Mode
Each PCM 81 effect has its own Mix parameter, with the Mix setting stored as
an integral part of the effect. Mix Mode allows you to override these individual
Mix settings and set a global Mix value for all effects. This is useful when using
a mixing console's controls to set the amount of wet signal in a mix. In such a
case, you can use this control to set all PCM 81 effects to 100% wet.
When shipped, the PCM 81 has the Mix Mode set to Pgm. This setting
determines that effects will be loaded with their stored Mix settings, and allows
the individual Mix controls in the edit matrix of each effect to be adjusted from
0-100% Wet. To set a global Mix value, use ADJUST to select Global, press
Load/
✱
to display the current value, and use ADJUST to assign any value from
0-100% Wet.
