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.
