NetPA 502 AT Two Channel Amp with Dante - 50 Watts/Ch 60-1500-01

The Extron NetPA 502 AT is a half rack 1U, convection cooled power amplifier featuring Dante® digital audio networking. It delivers two channels of 50 watts into 4 ohms. The NetPA® amplifier receives two channels of audio from a Dante-enabled device over a standard local area network, allowing for decentralized distribution of audio throughout a building. In addition to amplifying incoming Dante audio, the NetPA amplifier features line level outputs that can simultaneously feed an additional speaker zone or audio system. It is an ENERGY STAR® qualified amplifier with an Extron exclusive, highly efficient, advanced Class D amplifier design. It also features patented CDRS™ - Class D Ripple Suppression that provides improved signal fidelity over conventional Class D amplifiers.

NetPA 502 AT

The NetPA 502 AT two channel amplifier delivers 50 watts rms per channel into 4 ohms or 25 watts rms per channel into 8 ohms. The NetPA 502 AT is ideal for amplification of voice or program content to stereo speakers, or two sets of 8 ohm ceiling speakers in a dual zone application. The professional grade amplifier also features greater than 90 dB signal-to-noise ratio and less than 0.1% THD+N.

Dante Audio Networking

Dante provides scalable audio transport, with Dante Domain Manager support, over a local area network using standard Internet protocols. The family of Dante-enabled products from Extron work together as part of a complete networked audio system solution and integrate with other Dante-enabled products to create efficient system designs. With AES67 support, NetPA amplifiers accommodate a range of audio routing needs in a variety of applications.

Setting up a network of Extron Dante-enabled products, including the NetPA 502 AT amplifier, requires Dante Controller software. Dante Controller is used to easily assign an output from a Dante-equipped device, such as the Extron DMP 128 AT, to an input on a NetPA amplifier.

Energy Efficient Amplifier with Auto Power-Down

The NetPA 502 AT ENERGY STAR qualified amplifier is an energy efficient product that conserves energy and reduces costs. It includes an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity.

Professional Integration Features

The NetPA 502 AT can output incoming Dante channels as fixed line level signals to simultaneously feed the audio into another speaker zone or audio system. The amplifier also includes recessed, detented level controls located on the rear panel to prevent tampering. These controls facilitate adjustment of audio system gain structure, or setting an individual level for each zone. Additionally, the NetPA 502 AT amplifier includes multiple protection circuits that momentarily activate when an abnormal condition, such as overheating, is detected. An advanced, automatic clip limiter protects speakers from clipping distortion.
