AudiaEXPI-D
Digital Input Expander
AudiaEXPI-D is a digital input expander for Audia®, the benchmark in digital audio systems for
demanding professional sound installations. AudiaEXPI-D accepts eight channels of digital audio input
and provides eight channels of digital audio output via CobraNet®. AudiaEXPI-D can simply add inputs
to a centralized system, or it can extend system boundaries by providing inputs in remote locations.
AudiaEXPI-D is represented as a block in Audia software, for easy inclusion into any system design.
AudiaEXPI-D may also be used to provide inputs to other CobraNet compliant systems or devices.

Word Clock output on BNC connector
rotary encoder with LCD for programming/setup
logic inputs for recalling preset configurations
included as block in AUDIA system design software
may be used with any CobraNet compliant system
RoHS compliance and AES grounding practices
CE marked and UL listed power source
covered by Biamp Systems' five-year warranty
ARCHITECTS & ENGINEERS SPECIFICATION
The Digital Input Expander shall provide four pairs of AES3 transformer coupled digital audio inputs on XLR connectors. Two of
these pairs shall be selectable instead as SPDIF inputs on RCA connectors and the other two pairs shall be selectable instead as
TOSLINK inputs. Eight channels of digital audio output shall be provided via CobraNet
word clock output shall be provided on BNC connector. A rotary encoder and LCD screen shall be provided on the front panel for
programming and setup. Logic Inputs shall be provided for recalling preset configurations.
The Digital Input Expander shall be represented as a functional block within Audia
designs. The Digital Input Expander shall also be capable of providing digital audio inputs to other CobraNet compliant systems or
devices. The Digital Input Expander shall be CE marked with a UL / C-UL listed power source, and shall incorporate AES48-2005
Grounding & EMC practices. The Digital Input Expander shall be compliant with EU Directive 2002/95/EC, the RoHS directive.
Warranty shall be 5 years.
The Digital Input Expander shall be AudiaEXPI-D.
