Architect and Engineer Specifications: xIO 4×4.

The half rack device shall provide four analog mic/line inputs that are adjustable from line to mic level with coarse gain and phantom power and four analog line outputs. Levels and phantom power shall be controllable via DSP modules in software. Audio connections shall be accessed via rear panel 3.5 mm Phoenix® connectors.

Network audio expansion shall be provided by the Dante protocol. The connector shall be 100 Base-T RJ45 utilizing CAT6 cable.

A designer software application shall be provided that operates on a Windows computer, with network interface installed, running Windows® 7 or higher operating system. Computer connection for configuration shall be via a hosting DSP unit’s rear panel Ethernet connector that communicates with the devices via Dante.

The front panel shall include indicators for POWER, ETHERNET, and DANTE.

Audio conversion shall be 24-bit, 48 kHz and the dynamic range shall not be lower than 115 dB, A-weighted with a maximum input level of +23 dBu and maximum output level of +24 dBu.

The device shall be powered over Ethernet (PoE) by an included 802.3af Class 0 PoE injector. The device shall meet UL/CSA and CE safety requirements and comply with CE and FCC Part 15 emissions limits. The device shall be RoHS compliant. The chassis shall be constructed of cold rolled steel, and may be surface mounted or mount into a standard 19” 1U EIA rack using available mounting kits. The device shall be a Symetrix xIO 4×4.
