Features - Extron electronics NetPA 502 AT User Manual

Setting up a network of Extron Dante-enabled products, including the NetPA amplifiers,
requires 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.
The NetPA 502 AT and NetPA 1001-70V AT can output incoming Dante channels as line
level signals to simultaneously feed the audio into another speaker zone or audio system.
Both amplifiers also include 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 amplifiers include
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.

Energy efficient Class D Amplifier — The NetPA amplifiers feature an Extron
exclusive, highly efficient, advanced Class D amplifier design to conserve energy and
reduce costs.
Receives input signals via the Dante audio network — Select one or two channels
from remote digital signal processors on the Dante network to be brought into the
NetPA for amplification.
Dante audio networking provides a wide range of expansion capabilities —
Dante-equipped audio products provide scalability for creating larger audio systems
over a local area network using standard Internet protocols.
Dante audio to line level outputs — The NetPA provides 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
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 — Ensures the amplifier is always active for 24/7
operation in critical applications. This feature can be
.
internal jumper
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.
Convection cooled, fanless operation — The NetPA does not require internal fans or
vents for cooling, ensuring quiet, reliable operation.
Ultra low inrush current — Allows multiple NetPA amplifiers to be powered
simultaneously without overloading power circuits. This eliminates the need for power
sequencing.
Rack-mountable 1U, half rack width enclosure
Auto power-down with fast power-up — The NetPA includes 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.
Rear panel recessed, detented level controls
Automatic clip limiter — Detects actual onset of clipping by comparing input and
output waveforms.
Multiple protection circuits — Activate during output shorts, thermal overload, or DC
