Front Panel Familiarisation
LCD Screen : shows menu options,
channel information, and various
parameters as they are adjusted.
Next Key : moves forwards through the list of available parameters.
Back Key : moves back through the list of available parameters.
Menu Key : activates the main menu. A second press selects the last
menu edited. Selection of different menus may be accomplished using
the Back and Next keys, or by turning the ‘Freq’ encoder.
Enter Key : enters the chosen menu and confirms choices.
Bypass Key : bypasses the currently selected parametric EQ section. Note that,
for safety reasons, the high and low pass filters cannot be bypassed using this key.
Quit Key : exits the menu.
Encoders : three velocity sensitive controls allow the
relative parameter displayed on the LCD screen to be
adjusted.
PC Card : PCMCIA card slot allows back-up of input
memory sets, unit cloning data and facilitates the download of
software updates.
Gain Keys : one for each input and output, allowing instant access
to the gain screen for the selected channel. The accompanying LED
illuminates whilst editing is active.
Input Meters : display available headroom below clipping. The
yellow ‘0dB’ LED illuminates at 3dB below the actual clipping point
of the input section. The red ‘D.Clip’ LED shows digital overflow and can therefore
illuminate independently of the rest of the meter.
Output Meters: display headroom below limiting. The yellow
LED illuminates when the limit threshold is reached for that
channel. The red LED indicates 4dB of limiting.
Mute Keys: mutes the appropriate channel, and illuminates the
associated LED.
