Extron NetPA U 1004-70V – 4-Channel 70V Dante Power Amplifier
Product Overview
The Extron NetPA U 1004-70V is a four-channel Dante power amplifier that delivers 100 watts per channel at 70 volts in a 1U, half-rack enclosure. Built for distributed commercial audio, this 70V commercial power amplifier pairs networked Dante and AES67 transport with an integrated 8x8 DSP mix matrix, so integrators can route and process audio without adding a separate processor. Its plenum-rated, convection-cooled chassis stacks in a rack without wasting space on ventilation, making it a practical rack-mount amplifier with integrated DSP for decentralized systems. It is well suited to conference rooms, paging, and multi-zone 70V loudspeaker systems.
Product Description
The NetPA U 1004-70V is an advanced Class D 70 volt amplifier that Extron engineers designed in-house for permanently installed AV systems. Four independent channels each output 100 watts at 70 volts, driving distributed ceiling, pendant, and surface loudspeakers across large rooms and multiple zones. Because audio arrives over the network, this networked audio amplifier accepts four Dante inputs and integrates with Extron DMP Plus processors, AXI Dante interfaces, and any AES67-compatible source. The integrated 8x8 mix matrix lets any analog or Dante input route to any amplifier output, with gain, filters, dynamics, ducking, and delay handled on board.
The parallel Dante and analog line outputs carry post-DSP signal, so you can feed additional amplifiers or recording systems while keeping consistent processing. As a half-rack 1U power amplifier, two units mount side by side in a single rack space using the included brackets, and convection cooling means no fans and no wasted vent space above the unit. The InstaWake auto-standby feature keeps the amplifier Ecofficient Level 3 compliant, drawing minimal power at idle and returning to full output in under 100 milliseconds. For above-ceiling installation, the unit becomes a plenum-rated power amplifier when used with the optional Flexible Conduit Adapter Kit (70-228-02). Control and monitoring are available over RS-232, USB, and Ethernet, and the internal Extron Everlast power supply is backed by a seven-year warranty for long-term reliability in commercial deployments.
Key Features
- Four channels at 100 W / 70 V — Each channel delivers 100 watts rms into a 70-volt distributed loudspeaker line, all channels driven.
- Dante and AES67 networking — A single RJ-45 port carries four Dante audio channels with Dante Domain Manager support for enterprise-scale routing.
- Integrated 8x8 DSP mix matrix — On-board processing provides gain, filters, dynamics, ducking, and delay so no external processor is required.
- InstaWake auto-standby — The amplifier exits standby in under 100 milliseconds on signal detection while meeting Ecofficient Level 3 efficiency.
- Convection cooling, fanless — No fans or vents are needed, allowing units to be stacked without reserving rack space for airflow.
- Class D with patented CDRS — Class D Ripple Suppression removes high-frequency switching noise that can interfere with wireless microphones.
- Plenum rated with optional kit — Meets UL 2043 for above-ceiling plenum installation when used with the Flexible Conduit Adapter Kit (70-228-02).
- Parallel analog and Dante line outputs — Post-DSP line outputs feed additional amplifiers or systems while preserving consistent processing.
- Flexible control — Manage and monitor the amplifier over RS-232, USB, or Ethernet, or through a DMP Plus processor on the Dante network.
- Everlast power supply, 7-year warranty — The internal Everlast supply offers worldwide voltage compatibility and is covered for seven years.

Frequently Asked Questions
What loudspeakers is the NetPA U 1004-70V compatible with?
This model drives 70-volt constant-voltage distributed speaker lines with a 50 ohm minimum load. It works with Extron SoundField and SpeedMount 70/100 V ceiling, pendant, and surface speakers, as well as any third-party 70 V loudspeakers.
How is audio delivered to the amplifier?
Audio can arrive over Dante or AES67 on the network RJ-45 port, or through four analog mic/line inputs. The unit integrates with Extron DMP Plus processors and AXI Dante interfaces using Dante Controller software.
Can it be installed above a ceiling in a plenum space?
Yes. The amplifier meets UL 2043 for plenum airspaces when installed with the optional Flexible Conduit Adapter Kit (part 70-228-02), allowing concealed above-ceiling placement.
How does it fit into a rack, and does it need ventilation space?
Two units mount side by side in a single 1U rack space using the included single and dual rack-mount hardware. Convection cooling means no empty rack units are required above the amplifier for airflow.
How is the amplifier controlled and monitored in an AV system?
Control and status monitoring are available over RS-232, USB, and 10/100 Ethernet, or through a DMP Plus Series processor across the Dante network using Extron DSP Configurator software.
