4.2.1 Introduction

The LCD Control Screen and its controls let you confi gure the amplifi er 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.
