DESCRIPTION
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 and 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 command. The AXI 44 AT also features four line level outputs
for routing any four Dante channels from the network to the audio
system. The AXI 44 AT interfaces with any Dante-equipped audio
product, such as an Extron DMP 128 Plus AT audio DSP processor,
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.
KEY FEATURES
AA Four mic/line inputs for transmitting audio to 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.
AA Four line level outputs receive audio from a Dante network –
Four channels of high quality digital audio can be routed from
local or remote systems via Dante and converted to line level
analog audio, provided as balanced or unbalanced signals on a
captive screw connector.
AA Dante audio networking provides a wide range of expansion
capabilities – 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.
AA 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.
AA 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, DSP
Configurator Software, or SIS commands.
AA Power over Ethernet allows the AXI 44 AT to receive power
over a single Ethernet cable, eliminating the need for a local
power supply
AA Highly reliable, energy-efficient external universal power
supply optional, part #70-775-01
AA 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.
