Navigating the LCD Control Screen
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.)
This image shows the parts of the LCD Control Screen. Its
functions are described below. NOTE: Listed functions can
also be controlled in System Architect.
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”.
Sweep Load Monitoring is not available in early I-Tech HD models.
