At NAB 2026, Sonifex introduced a practical new addition for broadcasters who need fast, reliable confidence monitoring across multiple audio formats. The new RMX-64DNT is a reference monitor designed for modern technical environments where operators need clear visibility, simple source selection and flexible monitoring across increasingly mixed signal paths.
For engineers working across radio, television and technical control, it is a straightforward solution to a very real problem, keeping track of more signals, across more formats, without adding unnecessary complexity.
Built for Mixed-Format Broadcast Audio
The RMX-64DNT is designed as a flexible audio reference monitor with broad format support built in from the start.
In its standard configuration, the unit can monitor up to 64 Dante channels and 64 MADI channels. That alone makes it useful in modern facilities where audio is often moving between IP and traditional digital transport at the same time.
Sonifex has also added flexibility through rear expansion slots, allowing users to configure the unit with additional formats depending on workflow requirements. These expansion options include:
- 12G-SDI
- AES digital
- analogue audio
That gives engineers the ability to tailor the unit to the environment it is being deployed into, whether that is a radio plant, television control room, production gallery or central technical area.
Clear Signal Visibility at a Glance
One of the more useful aspects of the RMX-64DNT is how clearly it presents signal activity.
The front display gives operators immediate visual feedback across incoming sources, making it easy to confirm signal presence, identify active paths and move quickly between sources when fault-finding or confidence monitoring.
In practical terms, that matters. In technical environments, fast visual confirmation often saves more time than deeper menu navigation ever will.
The RMX-64DNT is clearly designed with that reality in mind.
Touchscreen Monitoring That Makes Sense
The touchscreen interface is where the RMX-64DNT becomes especially useful in day-to-day operation.
Rather than forcing operators into rigid source switching, the unit allows channels to be selected directly from the display and assigned to the internal speaker output. Operators can quickly build a monitored mix, remove sources just as easily, and move between signal groups without slowing down.
That makes it far more useful than a simple confidence speaker. It becomes a practical listening and checking tool for real operational work.
For technical teams monitoring multiple feeds, confidence sources or contribution paths, this kind of direct control is a genuine advantage.
Built for Real Technical Environments
The RMX-64DNT also includes practical output control for real-world installation.
Users can cut the internal loudspeaker directly and route monitoring externally via rear XLR outputs for dedicated monitor speakers. That makes it easy to integrate the unit into a wider control room or technical monitoring chain without changing workflow.
This is a small feature, but an important one. It means the RMX-64DNT can sit comfortably in both standalone and integrated monitoring environments.
That flexibility makes it just as useful in smaller racks as it is in larger technical spaces.
Why It Matters
Broadcast monitoring has become more complex as facilities move across multiple transport standards and mixed signal environments.
Confidence monitoring used to be straightforward. Today it often means checking IP audio, baseband audio and embedded signals at the same time, often under time pressure.
The RMX-64DNT is useful because it simplifies that job.
It gives operators a clean, visual and direct way to monitor mixed-format audio without adding another layer of operational friction.
That is what makes it valuable.
Final Thoughts
The Sonifex RMX-64DNT is not trying to reinvent monitoring. It is solving a practical problem well.
For broadcasters managing Dante, MADI, SDI and mixed-format audio in technical environments, it offers a cleaner way to monitor signals, build confidence and move faster when it matters.
In modern broadcast facilities, that kind of practical utility goes a long way.
