Editing Parameters in Expert Mode
Expert mode allows detailed control of
all
processing parameters. Such parameters as attack/release times, gate
thresholds, multiband EQ settings and clipping drive are available at this level through a graphical block
diagram based interface. Expert Mode opens up a processing block diagram on the LCD screen. The first
blocks name “AGC Wideband” flashes, indicating that it’s the current parameter. To edit the AGC Wideband
parameters, click the jog-wheel. A list of the parameters relevant to that part of the processing algorithm is
shown (in this case; Phase Rotator, Wideband AGC, etc.). To edit another block’s parameters, rotate the jog-
wheel until the desired block name is flashing and then click the jog-wheel. Expert Mode editing is covered in
more detail in Chapter 7, Editing Presets.
Undo Edit
Restores the preset state from before the last edit operation.
Save to Card
Saves the current parameters to the PC Card, overwriting any previous settings saved under the current Preset
name. This function cannot be used with factory presets, since they cannot be changed. If you have made
changes to a factory preset and wish to save them, use
Save to Card as
to save the changes under a new name.
Save to Card As
Opens up a Preset Naming dialog box to allow the Preset name to be changed before saving the preset to the PC
Card. Preset names can be up to 12 characters in length. Click the jog-wheel to select a highlighted character to
be changed. Then rotate the jog-wheel to step through all the possible characters. Once the desired character is
displayed, click the jog-wheel to select that character. The highlighting moves to the next character. To insert a
new character between others, select the character after the insertion point, then change it to the “ins” symbol.
To delete an existing character select it, then change it to the “del” character. When the last character is
reached, rotate the jog-wheel to highlight “
Save”
. Click to save the preset. Highlight “
Cancel”
to cancel the
operation.

Input Master, Right Trim, and Input Phase
, instead.
Input Left & Input Right:
These level controls are active when either Analog input or AES/EBU input is
selected since their adjustments take place in the digital domain. The factory default setting is 0.0, which
corresponds to a nominal average program audio input level of +4 dBu. To change input level, rotate the jog-
wheel to adjust the level in 0.2 dB steps. Use the level bargraphs to make this adjustment so that signal peaks
read a bit higher than -15 dB with normal program audio. 0 dB corresponds to 0 dBFS (decibels below Full
Scale digital, i.e. the digital clip point) so be sure that peaks do not reach 0 dB regularly or distortion will result.
Input Master & Right Trim:
These level controls are active when either Analog input or AES/EBU input is
selected since their adjustments take place in the digital domain. The factory default setting is 0.0, which
