About this Guide

This guide describes the installation and operation of the NetPA 502 AT and NetPA 1001-
70V AT power amplifiers. Throughout this guide both models may be referred to collectively
as the NetPA AT.

Overview

The Extron NetPA 502 AT and NetPA 1001-70V AT are half rack 1U, convection cooled
power amplifiers featuring Dante digital audio networking. They deliver two channels of
50 watts into 4 ohms, or 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 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.
The NetPA 1001-70V AT mono amplifier delivers 100 watts rms for 70 volt high impedance
speaker systems in voice reinforcement and distributed audio applications. The professional
grade amplifier features greater than 90 dB signal-to-noise ratio and less than 0.1% THD+N.
The NetPA 1001-70V AT also includes a switch selectable, high pass filter that rolls off
frequencies below 80 Hz to prevent saturation of speaker transformers.
Dante enables audio system scalability over a local area network using standard Internet
protocols. Dante technology distributes up to 512x512 audio channels at 24-bit/48 kHz
over a single Gigabit Ethernet link with extremely low latency. Dante-enabled Extron
digital signal processors feature a built-in four-port Gigabit switch that provides direct
interconnection of multiple units to create larger, cost-effective audio matrixes.
