Extron Electronics is pleased to introduce the Extron NetPA 502 AT and NetPA 1001-70V AT, half rack 1U, convection cooled power amplifiers equipped with Danteâ„¢ digital audio networking. The NetPA 502 AT delivers two channels of 50 watts into 4 ohms, and the NetPA 1001-70V AT provides a single channel of 100 watts at 70 volts. NetPA amplifiers can receive audio from Dante-equipped audio processors over a standard local area network, greatly simplifying the cabling infrastructure for sharing audio across multiple rooms or floors in a building. In addition to amplifying incoming Dante audio, NetPA amplifiers feature line level outputs that can simultaneously feed an additional speaker zone or audio system. They feature an Extron exclusive, highly efficient, advanced Class D amplifier design, plus patented CDRS – Class D Ripple Suppression that provides improved signal fidelity over conventional Class D amplifiers.
“The NetPA amplifiers combine the highly-efficient core amplifier technologies found in the renowned XTRA Series amplifiers, with the flexibility and scalability of Dante audio networking in a compact enclosure,” says Casey Hall, Vice President of Sales and Marketing for Extron. “They receive audio channels from one or more digital signal processors on the Dante network, allowing for audio from a paging system or music to be shared throughout a building using standard Internet protocols.”
The NetPA 502 AT and NetPA 1001-70V AT are professional grade amplifiers, featuring greater than 90 dB signal-to-noise ratio and less than 0.1% THD+N. The amplifiers have recessed, detented level controls located on the rear panel that facilitate adjustment of audio system gain structure, or setting an individual level for each zone. They also have an ultra low inrush current draw to prevent power circuit overload that occurs when multiple amplifiers are switched on simultaneously. This feature eliminates the need for power sequencing in systems with multiple amplifiers in large centralized equipment racks, and prevents other equipment from experiencing power interruption from associated power surges.
A network of Extron Dante-enabled products, including the NetPA amplifiers, can be set up using Dante Controller software as well as DSP Configurator Software. Dante Controller is used to easily assign an output from a Dante-equipped digital signal processor, such as the Extron DMP 128 AT, to an input on a NetPA amplifier. Dante-equipped products are AVB – Audio Video Bridging ready.
