NOTE: Connecting the ampli er to a PC via USB allows the user to unlock the device should the password be forgotten. This function is performed through the PDX

Controller software.

4.3.3 SETUP 3/4: Device Name

Each PDX DSP ampli er can be individually named for easy identi cation within a rack or remotely via the PDX Controller software.

Naming the amplifier

1. Access the Device Name screen by pressing the SETUP button.

2. Press the SELECT encoder knob to access the editing screen.

3. Choose the backwards arrow by turning the SELECT knob and press it to delete the existing characters of the current preset name.

4. Rotate the SELECT encoder to select new characters from the row above the current amplifier name.

5. Insert selected characters into the new amplifier name by pressing the SELECT encoder knob. Once you select and insert a character, the editing cursor will change

direction and advance from left to right.

6. Save the new amplifier name by pressing the DOWN arrow key to activate the SAVE TITLE function.

4.3.4 SETUP 4/4: Contrast

The Contrast screen allows you to adjust the LCD screen’s contrast level. The Contrast parameter ranges from 1–30, with 30 representing maximum contrast. Rotate

Saving a preset

1. Make sure the “Save Preset” option appears on the screen. (Rotate the SELECT encoder to toggle between “Load Preset” and “Save Preset.”)

2. Press the SELECT encoder knob to access the DSP’s internal Preset list on the next sub-screen. The correct sub-screen will disp

lay the EDIT TITLE and SAVE PRESET

options on the right-hand side of the screen.

3. Scroll through the list until you find an EMPTY Preset slot or another Preset you wish to overwrite.

4. If you wish to edit your Preset title before saving, press the UP arrow button to choose the EDIT TITLE option.
