Extron Now Shipping Six Input, Four Output Audio Expansion Processor With AEC & Dante

Places six mic/line sources onto a Dante audio network, and routes any four Dante channels from the network to an amp or other destination

Extron Electronics has announced the new AXP 64 C AT, an audio expansion processor with six mic/line inputs and four line outputs for remote connectivity to a Dante-enabled DMP 128 audio system.

The AXP 64 C AT is used to place six mic/line sources onto a Dante audio network, and route any four Dante channels from the network to an amplifier or other destination.

It incorporates Extron ProDSP with gain, filtering, and dynamics processing for all inputs and outputs. Four of the inputs also include AEC, 48 volt phantom power, and dedicated control ports for mic control. FlexInputs offer the additional capability to process Dante channels in place of the first four local inputs.

A single Ethernet cable from one AXP 64 C AT, or several linked units, to a central equipment rack greatly reduces the effort and expense of pulling one cable for each endpoint.

“Integrators need a way to eliminate the effort and expense associated with pulling multiple cables to the digital signal processor in the equipment rack from the microphones and audio amplifiers in the meeting space,” says Casey Hall, vice president of sales and marketing for Extron. “The AXP 64 C AT routes signals from the meeting room to one or more DMP 128 AT digital matrix processors on the Dante network but also receives and processes signals back to the room from the network all using a simple Ethernet link.”

The AXP 64 C AT includes four independent channels of AEC with advanced algorithms for fast convergence and optimal intelligibility in conferencing applications. The AEC-enabled inputs also offer FlexInput capability to route a Dante channel through the processor 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.

In an installation with a large number of mics, the AXP 64 C AT audio expansion processor places audio signals onto the Dante audio network using standard IP networking. Signals are received as expansion inputs at one or more DMP 128 AT processors.

A sound system designer can incorporate several AXP 64 C AT or Extron AXP 50 C AT audio expansion processors to create a large mixing matrix with up to 56 remote inputs and 24 outputs per DMP 128 AT using the built-in four-port Gigabit switch. This simplifies scalability and the audio cabling infrastructure by avoiding long analog mic cable runs.

To further simplify the audio cabling infrastructure, the AXP 64 C AT converts four channels from the Dante network to line level audio signals, processes them, and routes the optimized audio to local sound reinforcement systems.
