Suggested Replacement: NetPA U 1002

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.

Features

Receives input signals via the Dante^® audio network — Select two channels from any remote Dante-enabled device on the network to be brought into the NetPA 502 AT for amplification.

Outputs: Two balanced or unbalanced line level on 3.5 mm, 6‑pole captive screw connector; two speaker outputs on screw-lock, 5 mm, 4‑pole captive screw connector

100 watts rms output power:
2 x 50 watts @ 4 ohms or 2 x 25 watts @ 8 ohms

ENERGY STAR^® qualified amplifier — The NetPA 502 AT is an ENERGY STAR qualified amplifier and energy efficient product that conserves energy and reduces costs.

Dante audio networking provides a wide range of expansion capabilities — Dante-equipped audio products, including the NetPA 502 AT, provide scalability for creating larger audio systems over a local area network using standard Internet protocols.

Dante audio to line level outputs — The NetPA 502 AT provides two fixed line level outputs that allow the incoming Dante audio to be delivered to additional speaker zones, or another audio system such as an ALS - assistive listening system.

Professional grade signal-to-noise and THD+N performance — The NetPA 502 AT delivers professional grade performance with greater than 90 dB signal-to-noise ratio and THD+N of less than 0.1%.

Defeatable auto power-down timer for 24/7 applications — Ensures amplifier is always active for 24/7 operation in critical applications.

Extron Patented CDRS™ - Class D Ripple Suppression — CDRS is an Extron Patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones.

Convection cooled, fanless operation — The NetPA 502 AT does not require internal fans or vents for cooling, ensuring quiet, reliable operation. It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications.

Ultra low inrush current – no need for power sequencing — Allows multiple NetPA^® amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing.

Rack-mountable 1U, half rack width enclosure — The NetPA 502 AT reduces rack space requirements for many installations.

Auto power-down with fast power-up — The NetPA 502 AT meets ENERGY STAR qualification requirements with an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, dramatically reducing power consumption. It quickly returns to full power status in less than one second upon signal detection. This auto power-down feature can be defeated to allow for 24/7 operation.

Rear panel recessed, detented level controls — Provide attenuation of input signals for adjusting audio system gain staging as well as two‑zone applications. They are located on the rear panel to prevent users from tampering with level adjustments.

Automatic clip limiter — Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced without audible artifacts to protect speakers from clipping distortion.

Multiple protection circuits — Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers.

Remote standby port — Enables the NetPA 502 AT to be remotely powered down when not in use, reducing operating cost.

5 mm screw-lock captive screw connectors for speaker connections — Enable simple, secure connections with 22 to 12 AWG speaker cables.

Front-mounted signal and protection indication LEDs — Provides convenient indication of input signal presence and protection circuit activation.

Link LED indicator for Dante port — Provides visual indication of synchronization to the master clock on the Dante network.

Internal Extron Everlast™ power supply — Provides worldwide power compatibility, with high‑demonstrated reliability and low power consumption for reduced operating cost

Extron Everlast Power Supply is covered by a 7‑year parts and labor warranty
