DSP 260
8 Owner‘s Manual
3 Controls & Connection
3.1 Front Panel
1 – USB Connector
USB 1.1 port for connection to a PC running Windows XP or Vista. With a connected PC you may run the
DSP 260 Editor Graphic User Interface Application. The DSP 260 can be operated, edited and configured
for installation with an easy to use, intuitive interface. Any available firmware updates downloadable from
www.dynacord.com can be loaded via the USB port as well; allowing for easy in-field updates.
2 – Input Level Meters
The DSP 260 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 DSP 260. 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 DSP 260 is a digital audio device – and
digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DSP 260’s input
does clip, reduce the output level of the connected mixer. The -6dB PAD button at the rear panel can be
used for adjusting the input level also.
3 – LCD Display
The back-lit, 192 x 32 graphic LCD display allows for operation and editing of the DSP 260 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 DSP 260’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.
