Controls & Connection
Front Panel
1 – USB Connector
USB 1.0 port for connection to a PC running Windows XP or Vista. With a connected PC you may run the DC-One Editor Graphic User Interface Application. The DC-One can be operated, edited and configured for installation with an easy to use, intuitive interface. Any available firmware updates downloadable from www.electrovoice.com can be loaded via the USB port as well; allowing for easy in-field updates.
2 – Input Level Meters
The DC-One does not itself have input level controls. Proper input level adjustment is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device), as the vast majority of today’s mixer-outputs are dBu calibrated. When the mixer is operating at optimal levels, so is the DC-One. The input meters monitor the input level of either analog or AES-EBU inputs, depending on the input mode selection set in the Setup Menu.
Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (Yellow) LED indicators. As the DC-One is a digital audio device – and digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DC-One’s input does clip, reduce the output level of the connected mixer.
3 – LCD Display
The back-lit, 192 x 32 graphic LCD display allows for operation and editing of the DC-One without the need for an attached PC. The contrast can be set in the Setup Menu for varying lighting conditions and viewing angles.
The LCD display works in conjunction with Menu buttons, Select buttons and Value buttons - to operate, navigate and edit the DC-One’s parameters.
In Run mode, the LCD displays the number and name of the currently selected factory or user preset. Pressing the Recall or Store buttons switches to their respective menus. Pressing the Edit or Setup menu buttons switches the display to the last edited parameter.
In Edit and Setup mode, the top line of the LCD display shows the currently selected parameter edit screen. Use the Select buttons to activate the top line of the display, and the value buttons to scroll through available parameter edit screens.
