Extron is now shipping its née AXP 50 C AT, a five input audio expansion processor with Extron ProDSP for integrating remote microphones and other sources into a Dante-enabled Extron DMP 128 audio system. A single Ethernet cable from one AXP 50 C AT, or several linked units, to a central equipment rack significantly reduces the effort and expense of pulling one cable for each mic. The AXP 50 C AT provides 48 volt phantom power and a digital control port to all mic/line inputs. Dedicated signal processing is available for each input, including gain, filtering, dynamics, and AEC – acoustic echo cancellation. FlexInputs offer the additional capability to process a Dante channel in place of a local input. The intuitive DSP Configurator Software makes it quick and easy to set up DSP parameters and AEC on the AXP 50 C AT.

In an installation with a large number of mics, the AXP 50 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 50 C AT input expanders to create large mixing matrices of remote inputs for DMP 128 AT processors using the built-in four-port Gigabit switch. This simplifies scalability and the audio cabling infrastructure by avoiding long analog mic cable runs. The 1U, half rack width enclosure enables installation underneath a conference table, inside a credenza, or anywhere microphones or other sources may be situated.
