State of the Art DSP for Today’s Applications
The Electro-Voice DC-One is a 2-in, 6-out digital signal processor for loudspeaker management and
optimization. Built on EV’s DSP heritage, DC-One is the next generation of EV signal processing,
proven in thousands of installations and live applications around the world including the Olympics,
the FIFA World Cup, Live 8, and Live Earth. Throughout the years, EV has set industry standards for
superior processing solutions featuring outstanding dynamic range, legendary reliability, and powerful
DSP—options normally associated with units costing many, many times more. World class floating point
processing ensures a total sonic match with all existing EV loudspeaker presets from existing and future
processing platforms and also allows expansion of the DC-One processing features with new releases.
DC-One packages this level of performance and flexibility into a system that balances ease of use with
sophisticated functionality.
Taking Your System to the Next Level
Ask yourself these questions:
How do I get the most out of my Electro-Voice PA? DC-One provides all the tools to optimize your system
with ease. Factory designed presets are available at the push of a button to automatically configure
processing, including equalization and crossovers, that is unique to your setup. Not only does this provide
the highest sonic performance, it also protects your loudspeaker components for maximum longevity.
How do I manage multiple rental systems? DC-One is designed to handle a multitude of applications
with varying degrees of access to control parameters. One event may call for a small, portable system
with limited access for simple house EQ, while another may need a larger system with deeper access
to crossover and limiter functions. In any case, DC-One can be configured to the situation, scaled up or
down, sophisticated or simple, always protecting your investment.
What level of control is available? DC-One gives experienced system designers a full complement of
precision tools for loudspeaker management and tuning normally associated with more expensive units. The
user friendly software interface allows complete control of all parameters for the most critical applications,
from house of worship to high-end club installations.

DC-One Editor Software gives you the option of getting deeper
into system control with an intuitive user interface. Functionally, DC-
One Editor Software utilizes graphics and color schemes that are
stylistically inspired by popular recording software applications. A
picture is worth a thousand words – rather than editing your sound
with text and numbers, the graphic interface allows you to immediately
visualize and control parameters and settings, live and in real time.
Unique Delay Adjustment Interface – Users can position
the system components as they actually exist in space, making it
possible to move devices forward or backward in the environment.
Multiple channel linking options are provided, and total delay time is
always displayed.
Selectable Front Panel Access – Variable parameter lockout
– keep your system and your investment safe by blocking access to any
settings or parameters. The lock icons denote which parameters are not
accessible from the front panel.

DC-One Editor Software allows you to take the control and
configuration of your system to the next level. Operating on a
Windows PC, the DC-One Editor connects to the hardware
via a simple, plug-and-play USB interface.
All changes and edits happen in real-time, allowing you to
immediately hear the results of any adjustments. All parameters
of the system, including VU meters, mute switches, level
controls, and DSP functions are instantly visible, providing an
in-depth overview of your systems’s operation.
DC-One offers maximum flexibility: all changes can be stored in
project files on your PC; presets can be stored in the DC-One
hardware or software, to be recalled at any time.
Whether you have multiple loudspeaker systems to manage
or simply want to store different EQ settings for the different
venues in which you work, DC-One Editor Software provides
all the tools and flexibility you’ll need to make your sound better
and your gig easier.
