Inputs — Six balanced or unbalanced mic/line level processed inputs, four with AEC,
are provided on 3.5 mm, 3-pole captive screw connectors.
Phantom power — 48-volt phantom power is provided on the first four inputs.
Independent AEC — Four independent channels of high performance AEC, as well as
selectable noise cancellation, are provided on the first four inputs. Extron AEC features
advanced algorithms that deliver fast echo canceler convergence for optimal intelligibility
in situations that challenge AEC performance, including double-talk and the use of
wireless microphones at the near end.
FlexInput Channels — The first four inputs provide FlexInput capability to route a
Dante channel in place of a local mic/line input. The flexible input selection enables the
AXP 64 C AT to process audio from remote wireless microphones, wallplates, and other
sources from anywhere on the Dante network.
Flexible pre-processed and post-processed input signal routing — The internal
DSP architecture sends both pre-processed and post-processed input feeds from the
first four inputs onto the Dante network. The last two inputs provide post-processing
feeds to the Dante network. This provides the flexibility to limit the signal processing on
mic input signals for recording, assistive listening, or voice reinforcement feeds, while
applying full processing and AEC to a conferencing application.
Outputs — Four balanced or unbalanced line level outputs are provided on a 3.5 mm,
6-pole captive screw connector.
AT Expansion outputs — Ten DSP AT expansion outputs are placed directly onto a
Dante audio network.
Dante-to-line level outputs — Four Dante-to-line level outputs convert Dante audio
network signals to line level output signals with filtering and dynamic processing tailored
for the local environment.
Digital I/O — One digital input, ground, and dual digital outputs at each mic/line input
allow for external triggering, such as mic activation and muting and illuminating status
LEDs.
Expansion through Dante audio networking — The Dante equipped AXP 64 C AT,
in conjunction with the DMP 128, provides scalability for creating large audio
AXP 64 C ATes over a local area network using standard Internet protocols. Dante
technology distributes up to 512x512 audio channels at 24-bit/48 kHz over a
single Gigabit Ethernet link. A built-in four-port Gigabit switch also provides direct
interconnection of multiple AXP 64 C AT units to create large, cost-effective audio
AXP 64 C ATes.
Four-port Gigabit switch — The built-in, four-port Gigabit switch provides network
pass-through to additional AXP 64 C AT units and direct interconnection with
DMP 128 AT units.
ProDSP 32/64-bit floating point signal processing — The AXP 64 C AT features
32/64-bit floating point audio DSP processing, which maintains very wide dynamic
range and audio signal transparency, to simplify management of gain staging while
reducing the possibility of DSP signal clipping.
Studio grade 24-bit/48 kHz analog-to-digital converters — Professional
converters fully preserve the integrity of the original audio signal.
Low latency DSP processing — The AXP 64 C AT features very low, deterministic
latency from input to output, regardless of the number of active channels or processes.
While latency increases in channels with AEC enabled, overall latency remains low,
keeping audio in sync with video.
