Nexia® CS

DSP Conference System

Nexia CS is a digital signal processor with 10 mic/line inputs and 6 mic/line outputs. Intended for a
variety of conferencing applications such as boardrooms, courtrooms, and council chambers, Nexia CS
includes a broad selection of audio components, routing options, and signal processing. The internal
system design is completely user definable via PC software, and can be controlled via daVinci™
software screens, RS-232 control systems, and/or a variety of optional remote control devices.
Multi-unit Nexia systems can be created utilizing Ethernet and NexLink digital audio linking.

ARCHITECTS & ENGINEERS SPECIFICATION

The DSP conference system shall provide ten balanced mic/line inputs and six balanced mic/line outputs on
plug-in barrier-strip connectors. Inputs and outputs shall be analog, with internal 24-bit A/D & D/A converters operating at a
sample rate of 48kHz. All internal processing shall be digital (DSP). NexLink connections shall allow sharing of digital audio within
multi-unit systems.
Software shall be provided for creating/connecting DSP system components within each hardware unit.
Available system components shall include (but not be limited to) various forms of: mixers, equalizers, filters, crossovers,
dynamics/gain controls, routers, delays, remote controls, meters, generators, and diagnostics. Ethernet communications shall be
utilized for software control and configuration. After initial programming, processors may be controlled via dedicated software
screens, third-party RS-232 control systems, and/or optional remote control devices. Software shall operate on a PC computer,
with network card installed, running Windows
and shall incorporate AES48-2005 Grounding & EMC practices. The DSP conference system shall be compliant with EU Directive
2002/95/EC, the RoHS directive. Warranty shall be 5 years.
The DSP conference system shall be Nexia
