4.2.1 Introduction
The LCD Control Screen and its controls let you configure the
ampli fier and access many features that before were available only
through a remote computer. Also, you can recall DSP presets via
the front panel. (Some DSP parameters cannot be adjusted with
the LCD Control Screen. That is done in System Architect.)
Figure 4.1 shows the parts of the LCD Control Screen. Its
functions are described below. NOTE: Listed functions can also be
controlled in System Architect.

Figure 4.1 Parts of the LCD Control Screen
Here’s how to access the various menus and settings in the LCD
control screen:
• Starting from the Attenuation screen, press Menu/Exit to go to
the Sample Rate screen.
• Press Next to go to the next item in the menu.
• Press Prev to go to the previous item in the menu.
• Turn or press either Encoder knob to change the value of the
dis played parameter.
• When you see a menu screen, push the knob once to see the
items in that menu. Or press Next to go to the next menu.
• Press Menu/Exit to leave the menu and return to the Attenuation
screen at any time.
Some menu items require confirmation: after you request a change,
the display might say “Press and hold.” To confirm a change, press
and hold an
Encoder knob. If you don’t want the change to occur
during a confirmation, turn the knob or wait five seconds.
The entire front panel or just selected screens can be locked out or
set to read only status using System Architect software. Locked-out
screens will either say “Lockout” or the individual parameter will
say “N/A”. If a change is attempted the screen will say “Changes
Disabled”.
