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
The AXI 44 AT accepts four analog mic/line sources, and digitizes them at 24-bit for output via Dante. It is connected into a Dante network over Ethernet using standard IP networking protocols. This avoids the effort and expense of pulling long analog cables back to the rack. With its small, quarter rack form factor, the AXI 44 AT can be easily mounted under a desk, in a lectern, or in millwork, as well as in a rack.
For additional integration convenience, AXI 44 AT interfaces can be remotely powered via Power over Ethernet - PoE, using Extron XTP PI 100 or XTP PI 400 power injectors, network switches equipped with PoE, or midspan PoE injectors.
The AXI 44 AT can accept any four audio channels from the Dante network and deliver them through its four line outputs. Four channels of high quality digital audio can be routed from local or remote systems via Dante, and converted to line level analog audio.
Dante enables audio system scalability over a local area network using standard Internet protocols. The family of Dante-enabled products from Extron work together as part of a complete networked audio system solution and integrate with other Dante-enabled products to create efficient, scalable system designs. They accommodate a wide range of audio routing needs in a variety of applications.
Setting up a network of Extron Dante-enabled products, including the AXI 44 AT, requires Dante Controller software. Dante Controller is used to easily assign an output from an AXI 44 AT to an input on a Dante-equipped device, such as the Extron DMP 128 Plus AT. Similarly, an output from a Dante-equipped device can be assigned to appear at one of the line level outputs on an AXI 44 AT.
