Summary: At InfoComm 2026, NCS spoke with Audio-Technica’s Mark Donovan for a closer look at the new D50 Digital UHF Wireless System. Designed for commercial AV environments, the D50 combines high channel density, Dante connectivity, PoE+ power, flexible transmitter options, and a compact rack footprint to help integrators build more efficient and scalable wireless audio systems.
At InfoComm 2026, NCS caught up with Mark Donovan, CTS-D, CTS-I, Director of Commercial Applications at Audio-Technica, for a closer look at the company’s new D50 Digital UHF Wireless System.
Designed for demanding commercial AV environments, the D50 combines high wireless channel density, a compact rack footprint, Dante audio networking, PoE+ power, flexible transmitter options, and network-based management in one platform.
There is a lot packed into the system, but one theme came through clearly during Mark’s demonstration: efficiency.
The D50 is designed to make better use of RF spectrum, rack space, network infrastructure, power, and charging while giving integrators the flexibility to configure wireless audio around the needs of each environment.
More Wireless Channels in Less Rack Space
One of the first things Mark pointed out was just how much Audio-Technica fit into a half-rack receiver.
“This system packs a lot into a very small footprint, and it can be a little deceiving when you first look at it.”
A single half-rack D50 receiver can support four channels of wireless. Up to four receivers can be cascaded, allowing a 16-channel digital wireless system to fit within just two rack spaces.
That compact footprint can make a significant difference in commercial AV installations where equipment racks are already supporting DSPs, network switches, amplifiers, control processors, power equipment, and other AV hardware.
Reducing the amount of rack space dedicated to wireless gives system designers more flexibility without sacrificing channel count.
High Channel Density for Challenging RF Environments
Rack space is only one part of the equation. Available RF spectrum can be an even bigger consideration.
Wireless microphone systems operating in the UHF spectrum must work alongside the RF activity already surrounding a facility. That becomes especially important in dense urban environments, campuses, performance venues, and other locations where many wireless systems may be operating simultaneously.
The Audio-Technica D50 provides two operating density options.
In Standard Mode, the system can support up to 17 channels within a 6 MHz TV channel. When greater channel density is needed, High-Density Mode increases that number to as many as 47 channels within the same 6 MHz TV channel.
As Mark explained, that added density becomes particularly useful when designing a wireless system in a difficult RF environment, such as the middle of a large city.
Rather than simply focusing on how many microphones a system can support, Audio-Technica designed the D50 to give integrators more flexibility in determining where those channels can operate.
Dante and PoE+ Simplify the System
Another major part of Mark’s demonstration focused on how the D50 fits into the rest of the AV system.
The four-channel D50 receiver includes Dante connectivity, allowing digital audio to move directly onto the network.
The network connection can also provide power through PoE+.
That means the receiver can receive both networked audio and power through the infrastructure already supporting the AV system, reducing the need for additional power supplies and unnecessary wiring.
As Mark explained during the interview, the idea is simple: connect the system through the network, cascade the receivers, and use that connection for both power and audio.
For modern AV systems increasingly built around networked technologies, that can make the wireless platform easier to incorporate into the overall design.
Flexible Transmitters for Different Spaces
Audio-Technica also designed the D50 around the different ways wireless microphones are used across commercial environments.
The system includes a compact metal body-pack transmitter for applications using lavalier and headworn microphones, along with a durable metal handheld transmitter.
Both use rechargeable lithium-ion batteries that are field replaceable, giving facilities another option for maintaining the system over its lifecycle.
The handheld transmitter also supports interchangeable Audio-Technica microphone capsules, allowing the microphone to be configured around different applications and performance requirements.
Then there is a third form factor that stood out during the demonstration: the D50 desk stand transmitter.
Designed for tabletop applications, the desk stand includes a 3-pin XLR connection and provides 24 volts of phantom power for compatible gooseneck microphones.
That makes it particularly relevant for environments such as:
- Boardrooms and conference rooms
- Council chambers
- Classrooms and lecture spaces
- Panel discussions
- Training rooms
- Government meeting spaces
The same D50 platform can therefore support handheld, wearable, and tabletop microphone applications rather than requiring an entirely different wireless system for each type of space.
Charging Designed Around Daily Use
Wireless microphone design does not stop with the transmitters themselves. Charging, storage, and day-to-day management are also important considerations.
During the interview, Mark demonstrated Audio-Technica’s charging options for the D50.
The handheld and body-pack transmitters can be placed directly into the charging station, or the rechargeable batteries can be removed and charged separately.
The system also supports charging for the desk stand transmitters.
The chargers can integrate into the equipment environment as part of the overall system rather than leaving facilities to develop a separate process for keeping microphones charged and ready.
For organizations operating multiple wireless microphones across meeting rooms, classrooms, training spaces, or event environments, that can make daily system management much easier.
Managing Wireless Beyond the Rack
The D50 also includes tools designed to help integrators configure, monitor, and maintain the wireless system after it has been installed.
Audio-Technica provides onboard spectrum analysis along with integration with its Wireless Manager software. Those tools can help evaluate RF conditions, configure the system, monitor performance, and perform walk testing throughout a space.
The D50 also includes onboard DSP capabilities and AES256 encryption for secure wireless audio transmission.
For larger installations, those management capabilities become increasingly important. Installing multiple wireless channels is one challenge. Being able to monitor, configure, troubleshoot, and maintain those channels efficiently is another.
Where the D50 Fits
The combination of high channel density, network connectivity, multiple transmitter types, and compact rack requirements makes the D50 particularly relevant for environments where wireless audio needs to scale.
A corporate facility could use handheld and body-pack transmitters across training rooms, presentation spaces, and multipurpose rooms while using desk stand transmitters in conference rooms or executive meeting spaces.
Schools and universities could apply the same wireless platform across classrooms, lecture halls, auditoriums, and performance spaces.
Government facilities and council chambers can benefit from the tabletop transmitter configuration, while theaters, houses of worship, and event facilities may place greater emphasis on channel density, RF performance, and microphone flexibility.
The right wireless system ultimately depends on the facility, local RF environment, required channel count, room use, network architecture, microphone requirements, and plans for future expansion.
The D50 gives integrators another way to address those requirements while bringing wireless audio more closely into the networked AV environment.
Designing the Complete AV System
Wireless microphones are only one component of a larger AV system.
Successful deployment means considering RF conditions, microphone requirements, audio processing, network infrastructure, equipment racks, control, charging and storage, room functionality, and how the technology will be supported after installation.
NCS Audio Visual Solutions include system design and integration for conference rooms, classrooms, training environments, collaboration spaces, presentation systems, and other commercial AV applications.
