Nexia® SP

DSP Speaker Processor

Nexia SP is a digital signal processor with 4 line inputs and 8 independent mix outputs. Intended for
speaker processing applications requiring line inputs feeding a larger number of discrete outputs,
Nexia SP 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.

FEATURES

• 4 balanced line inputs on plug-in barrier strips

ARCHITECTS & ENGINEERS SPECIFICATION

The DSP speaker processor shall provide four balanced line inputs and eight balanced 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 speaker processor shall be compliant with EU Directive
2002/95/EC, the RoHS directive. Warranty shall be 5 years.
The DSP speaker processor shall be Nexia

®

XP Professional/Vista. The DSP speaker processor shall be CE marked, UL listed,
