4. FRONT PANEL CONTROL FEATURES

To the right of the LCD dis-

play 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 corre-

spond 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 flashing 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.

The 4.8SP and 3.6SP are organized into 30 programmable presets, each completely defining the configuration

of all inputs and outputs along with their respective audio components. There are ten repeating preset configurations

pre-loaded into the unit which are simply starting points for common applications, and all can be modified, 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 first powered up, the last working preset is loaded, displaying the number and name last used

before the unit was turned off. Any modifications made to that preset before saving it will remain in the working preset

until either the modified preset is saved, or a fresh preset is recalled. When modifications to an existing preset are made

without saving, the display adds the text (modified) after the preset number.

There are four XLR audio inputs on the

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

processed 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.

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. Se-

lect an output channel to edit its

Source, Gain, Polarity, EQ, Delay,

Crossover, or Limiter functions.

Each input and output has a five 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.
