Extron’s new AXP 50 C AT is a five-input audio expansion processor with Extron ProDSP for integrating remote microphones and other sources onto a Dante-enabled Extron DMP 128 audio system. A single Ethernet cable to a central equipment rack can link multiple AXP 50 C AT units, avoiding the effort and expense of pulling one cable for each mic. The AXP 50 C AT provides 48 volt phantom power to its mic/line inputs. Dedicated signal processing is available for each input, including gain, filtering, dynamics, and AEC — acoustic echo cancellation.
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 matrixes of remote inputs for DMP 128 AT processors using the built-in four-port Gigabit switch. This greatly simplifies scalability and the audio cabling infrastructure by avoiding long analog mic cable runs. The compact 1U, half rack width enclosure enables convenient installation underneath a conference table, inside a credenza, or anywhere microphones or other sources may be situated.
