Front Panel Functions
1. Headroom Meter - Displays available headroom before system clipping occurs.
The bottom six LED's display between 30dB and 0dB of input headroom, with
the orange 0dB LED set at 3dB below clipping. The top, red LED displays digital
overflow and can therefore light without all other LED's becoming illuminated.
2. Menu Key - Selects last used menu choice to be previewed on the LCD display.
Pressing a second time selects the next menu choice. Menu selections can also
be viewed more quickly by using the Frequency control.
3. Down Key - Moves the display backwards through the list of available function
screens for the current output. [ Enter Key ] - With the menu LED lit, this key
performs the 'enter' function allowing the option for the current menu selection to
be displayed and then the chosen option confirmed.
4. Up Key - Moves the display forwards through the list of available function
screens for the current output. [ Quit key ] - With menu LED lit, this key
performs the 'quit' function, returning the unit to the basic default operating
mode from the existing menu selection.
5. Section Flat Key - Allows the currently displayed equaliser section or limiter to
be bypassed. The LED shows the status of the current section. (Note: The High
and Lowpass filters can not be bypassed using this method.) When the display
is showing 'delay time' holding this key down will cause the delay time control to
be adjusted in larger increments allowing quick adjustment. If an output channel
is selected and the display is showing ‘Delay time’, output phase will also be
shown.
6. Chan. Flat Key - Allows all the equaliser sections apart from the high and
lowpass filters to be bypassed for the current channel. The LED shows the
status of the current channel. The overall channel gain control may be set to
0dB by this action if required, by selecting the 'Gain Bypass Option' (see menu
options).
7. Scroll Key - Scrolls the screen through the available channels for the current
configuration.
8. LCD Display - Shows menu options, output information and various parameters
dependant on the menu selection.
9. Parameter Controls - The three rotary encoders allows the relevant parameter
to be adjusted.
