Visionary Solutions PNA-D4 – PoE+ 4-Channel Dante Network Amplifier

Product Overview

The Visionary Solutions PNA-D4 is a four-channel Class-D network audio amplifier with Dante/AES67 input, powered entirely over PoE+ with no external power supply required. Built for audio over IP installation in conference rooms, classrooms, and distributed commercial audio systems, the PNA-D4 places amplification directly at the speakers — above the ceiling, behind a display, or in a rack — wherever a single PoE+ network drop can reach. Its UL 2043 plenum-rated steel chassis makes it one of the few network amplifiers approved for installation in air-handling spaces.

Product Description

The PNA-D4 is part of Visionary's PacketAV line of network AV endpoints and behaves as a native network device from the moment it is connected. Four independent amplifier channels, each delivering 5 watts into 4 or 8 ohms (20 watts total), can be sourced from any Dante or AES67 audio stream on the network using Dante Controller or compatible third-party software — so one amplifier can serve four separate zones, or four speakers in one room, with per-channel routing flexibility. Because power arrives over the same PoE+ Ethernet cable that carries audio, integrators eliminate local AC outlets, wall-wart power supplies, and long speaker cable home runs, cutting both material and labor costs in commercial deployment. Class-D efficiency keeps heat low, and convection cooling means there is no fan to fail or generate noise in quiet meeting spaces. The UL 2043 plenum rating allows mounting in ceiling plenum air spaces common in commercial construction, and the compact steel chassis includes a mounting flange for secure installation. Power, Dante, and Status LED indicators simplify commissioning and troubleshooting. The PNA-D4 pairs naturally with Visionary's Duet and Dante-enabled AV over IP endpoints — add the MOD-DANTE module to an E4200/D4200 or browse the PacketAV E4100 encoder for complete AV over IP system designs.

Key Features

• Dante/AES67 Network Audio Input — Subscribes to any Dante or AES67 stream on the network for fully software-routable audio distribution.
• PoE+ Powered — A single PoE+ Ethernet connection provides both audio and power, eliminating local power supplies and AC outlets.
• Four Independent Channels — 5 watts per channel into 4/8 ohms (20 watts total) with independent source routing per channel.
• UL 2043 Plenum-Rated — Approved for installation in ceiling plenum air-handling spaces common in commercial buildings.
• Class-D Efficiency — Efficient amplification with low heat output; 25 W maximum and 2 W standby power consumption.
• Fanless Convection Cooling — Silent passive operation suitable for conference rooms and other quiet environments.
• High Audio Performance — Greater than 99 dB signal-to-noise ratio with THD+N below 0.1% at 5 W.
• Steel Chassis Construction — Commercial-grade build with mounting flange and Power, Dante, and Status LED indicators.
• Dante Controller Managed — Routing and control through Dante Controller or third-party control software, no proprietary tools required.

Typical Applications

• Conference room and boardroom program audio
• Huddle room and commercial meeting space speakers
• Training room and multi-purpose room audio zones

Frequently Asked Questions

Does the PNA-D4 need a power supply?
No. It is powered entirely by PoE+ from a compliant network switch or midspan injector, drawing 25 W maximum.

Can each channel play a different source?
Yes. The four channels are independent, and each can subscribe to any Dante/AES67 stream on the network through Dante Controller.

Is it safe to install above a drop ceiling?
Yes. The PNA-D4 is UL 2043 plenum-rated, so it can be installed in air-handling plenum spaces where most amplifiers are not permitted.

Will it work with AES67 devices that are not Dante?
Yes. The amplifier accepts both Dante and AES67 network audio, so it interoperates with AES67-compliant DSPs and endpoints from other manufacturers.

How loud is 5 watts per channel?
For near-field conference room, huddle room, and zone speech applications with efficient speakers, 5 W per channel is typically ample. For high-SPL program audio in large auditoriums, consider a higher-power amplification design — Creation Networks can help spec the right solution.

Does it integrate with Visionary AV over IP endpoints?
Yes. It pairs with Dante/AES67-enabled Visionary encoders and decoders, including Duet endpoints and 4200/5200-series units upgraded with the MOD-DANTE module.
