Extron AXI 44 AT 4 In 4 Out Dante Audio Interface

Extron AXI 44 AT 4 In 4 Out Dante Audio Interface

The Extron AXI 44 AT is a quarter rack width audio interface for integrating four mic/line sources onto a Dante®-enabled audio system. It features four mic or line inputs on 3.5 mm captive screw connectors, with switchable 48 volt phantom power. Input select, gain, and phantom power settings are controllable from the front panel, via DSP Configurator Software, or by SIS commands via USB. The AXI 44 AT also features four line level outputs for routing four Dante channels from the network to the audio system. The AXI 44 AT interfaces with any Dante-equipped audio processor, such as an Extron DMP 128 Plus AT, over a standard local area network, and can be powered via PoE. This allows a single network cable connection for bidirectional audio and power from a central equipment rack.

Features:

• Four mic/line inputs insert audio onto a Dante® network — Each input accepts a balanced or unbalanced mic/line level signal on a captive screw connector and includes selectable 48 volt phantom power.
• Four line level outputs extract audio from a Dante network — Four channels of high quality digital audio can be routed from up to two local or remote devices via Dante and converted to line level analog audio, provided as balanced or unbalanced signals on a captive screw connector.
• Dante audio networking provides a wide range of expansion options — Dante-equipped audio products, including the AXI 44 AT, provide scalability for creating larger audio systems over a local area network using standard Internet protocols.
• Dante Domain Manager and AES67 Support
• Studio grade 24-bit analog-to-digital and digital-to-analog converters with selectable sampling rates up to 96 kHz — Professional converters fully preserve the integrity of the original audio signal, with selectable sampling rates via Dante Controller.
• Input select, gain, and phantom power controls located on front panel and configurable through DSP Configurator Software — Settings can be modified from the front panel, SIS commands via USB, or through a DMP Plus Series processor over a Dante network
• Power over Ethernet allows the AXI 44 AT to receive power over a single Ethernet cable, eliminating the need for a local power supply
• 1U, quarter rack width metal enclosure — Compact, durable enclosure can be discreetly installed under a desk, in a lectern, in millwork, or in an AV equipment rack.
• Highly reliable, energy-efficient external universal power supply optional, part #70-1174-01 — Provides worldwide power compatibility with high reliability and low power consumption for reduced operating costs. Includes a ZipClip 100 Mounting Kit to securely mount an Extron power supply onto most surfaces, including tables and lecterns.
