4. FRONT PANEL CONTROL FEATURES

4.1 Function Keys and Data Wheel

To the right of the LCD display

are two unlabeled function keys and a

rotary data wheel. All audio and system

parameters are edited using these three

controls. Each of the two lines of text

on the LCD display correspond to a

dedicated function key, so that various

tasks on both lines may be selected using

their respective keys. The selected task is

highlighted by a ashing underscore beneath the word or number, and the parameter is then adjusted up or down with the data

wheel. The Esc key will exit any activity and return to the top level showing the preset number and name.

4.2 Presets

The 4.8SP and 3.6SP are organized into 30 programmable presets, each completely dening the conguration of all

inputs and outputs along with their respective audio components. There are ten repeating preset congurations pre-loaded into

the unit which are simply starting points for common applications, and all can be modied, renamed, and saved to suit the end

user. Please Note: In addition to the 30 preset numbers, a constantly refreshed Working Preset is used to take a "snapshot" of

all current settings should the unit be turned off before changes can be saved.

When the unit is rst powered up, the last working preset is loaded, displaying the number and name last used before

the unit was turned off. Any modications made to that preset before saving it will remain in the working preset until either the

modied preset is saved, or a fresh preset is recalled. When modications to an existing preset are made without saving, the

display adds the text (modied) after the preset number.

4.3 Input Select

There are four XLR audio inputs on the

4.8SP (three on the 3.6SP), and each input is pro-

cessed independently and may be routed to one or

several outputs. Select an input to edit its Gain, EQ,

and Delay settings, or to mute it. Signal routing

occurs in the output section.

4.4 Output Select

There are eight outputs on the

4.8SP (six on the 3.6SP), and each output

can obtain its source from any input or

combination of inputs. Select an output

channel to edit its Source, Gain, Polar-

ity, EQ, Delay, Crossover, or Limiter

functions.

4.5 LED Indicators

Each input and output has a ve segment LED array for audio level display, ranging from -20 through clipping. The

-20 LED is two-color, also serving as the Mute indicator by turning red. The meter scale is factory set so that 0 on the meter is

0dBu (0.775Vrms), however it can be easily changed to VU scale (0 = +4dBu, or 1.228Vrms) within the Util menu.
