“The RX2 is a complete audio production system which advances esRadio’s quality and efficiency to a whole new level,” comments ASPA’s technical project management team. “Designed for the most demanding broadcast and television environments, it has a scalable modular structure which offers maximum adaptability even in compact spaces. The installed configuration consists of two consoles, each with 18 physical faders. Each console comprises three fader modules and one control module but its capacity is doubled by a layering function which allows complete control over a greater number of channels without taking up additional physical space. The consoles incorporate 100 mm motorised faders with dust protection ensuring long-lasting high grade performance.

“As for its operation, the experience is fluid and intuitive thanks to the 10.1-inch touchscreens integrated into each section. These allow quick channel setup and centralised control. Programmable RGB buttons and flexible encoders adapt their function to the screen content, facilitating access to essential tools such as equalisers, dynamics and gain adjustments.

“At the processing level, the heart of each DHD system is its core, a compact unit that handles a massive audio matrix with up to 96 fully processed stereo faders. The core requires no hard drives or fans, ensuring quiet and low-maintenance operation – crucial for a studio environment. Compatible with Dante, AES67, RAVENNA, ST 2110 and MADI, the system is a futureproof solution for broadcasting.Your Content Goes Here

“For routing broadcast signals and communication between consoles we installed a DHD 52-7523 core matrix. Thanks to the logical functionality between the matrix, the consoles and DHD’s MatrixControl, it is possible to route the main broadcast submatrices, manage commercial breaks and select the studio for broadcast, both manually and using conditional logic.

“For the daily management of its broadcasts, esRadio uses the XFrame Radio automation software developed by ASPA’s R&D department. This system is characterised by its quality, adaptability and security. It is a technology benchmark in Spain and has a significant international presence. We would like to thank esRadio for their continued trust in ASPA and our professional solutions over the years.”

“The April NAB Show is a great opportunity for potential customers from North America, LATAM and Asia Pacific to get their hands directly on DHD products and talk with our representatives,” says Christoph Gottert, international sales manager. “We also look forward to meeting existing clients and demonstrating the expanded features in our latest firmware.”

DHD Firmware 10.4

Firmware 10.4 introduces three new configuration capabilities: Flex Channels, Mic Preamp Control and Channel Categories:

• Flex Channels allows access to more signals within the system. Source selection is performed from a pre-assigned input source list rather than from the pool of fader channels.

• Mic Preamp Control enables the A-Gain value of a microphone input to be set at any time without the need for assignment to a fader. The console’s touchscreen, the Views App or the API can be used to change the A-Gain parameter.

• Channel Categories are provided for fader channels. This allows the input source list to be filtered for specific signals.

Also new in Firmware 10.4 are four API-related features:

• New Control API for DHD AES67 interfaces: This allows secured connections using Tokens and HTTPS, enabling complete control over the stream parameters and interface settings. The format is similar to the already-released Control API for DHD cores.

• DHD Control API is now available as a Bitfocus Companion plug-in for the Elgato Stream Deck. It elevates the Stream Deck and similar devices into professional control surfaces for an extensive range of equipment and applications. A Stream Deck plug-in is also available for the DHD RM1 portable all-in-one audio production and broadcast system.

• TypeScript Library for DHD Control API on the Cores provides a function set for integration of DHD Control API in third-party software.

• Go Library for easy integration of DHD Control API in 3rd party software. This allows developers to build applications that interact with DHD devices, enabling seamless control and automation. The library is open-source under the MIT license, ensuring flexibility for a wide range of use cases. It is available now at https://github.com/dhd-audio.

DHD Routing Web App

DHD’s Routing Web App allows incoming sources and output ports to be securely assigned, viewed and managed by a nominated operator situated locally or remotely. HTML5-based, it runs directly on the web server integrated within the DHD processing core. Individual crosspoint matrices can be created and displayed graphically or as an input/output list. Matrix configurations can be stored as presets for fast selection and recall. The Routing Web App expands the range of DHD Web Apps to six, including the Assist App, Labels App, Snapshot App, System App and Views App. Each can be activated on a license basis.

This upgrade of Cadena Melodía’s studios in the visually striking Glass Building on Bogotá’s 45th Street sets a benchmark as the first station in Colombia to have entrusted its digitisation process to DHD’s SX2 control surface,” says Juan Pablo León, ASPA ANDINA’s technical director, commercial. “The system allows the interconnection of multiple studios via Cat6 Ethernet cable. In addition to their role as production mixers, the SX2 control surfaces can be used to perform audio routing from any available input to assigned outputs, including recording tools, booth monitoring, audio codec returns, and hybrid outputs. Routing is supervised through a 10-inch multitouch screen forming the upper section of each SX2 modular control surface.

“Each of the DHD control surfaces is equipped with motorised faders which have enabled the implementation of a virtual microphone mixer on a second layer. This optimises costs and space in the broadcast master, allowing for automatic mixing. Studio microphones are routed to one of the 16 available programme buses. This is controlled using DHD’s Automix tool, simplifying console operation.

“The DHD system supports a very large number of audio inputs and outputs in all existing audio formats. We also installed headphone jacks with independent level control. This allows independent return audio to each announcer, including specific talkback or commands from Cadena Melodía’s master control room when needed.

“A recently implemented telephone hybrid, fully remotely controlled from the DHD console, is compatible with traditional POTS/PSTN telephone lines and VoIP telephony. Wireless connectivity can also be achieved using smartphones with Bluetooth in two-way communication, allowing listener feedback. The system can also connect to GSM networks.

“In summary, we appreciate the trust of the entire management, technical and administrative team of Cadena Melodía de Colombia for allowing us to continue being part of the technological renewal of radio in the country.”

DHD innovations during 2025 included the introduction of the RM1 Pro ‘broadcast from anywhere’ system. “Our design aim with the established RM1 was to bridge the gap between podcast and broadcast,” comments Marc Hermann, managing director. “The new RM1 Pro version introduces extra capabilities for professional broadcasters who are working remotely, including tighter connectivity with DHD infrastructure located at their host broadcasting centre. Core control networking allows the exchange of logic commands with other DHD devices for talkback or on-air signalling. Users also gain access to individual DHD Toolbox configurations plus the ability to create an RM1 Pro user interface tailored to their workflow, including loudness metering functionality. RM1 Pro behaves like a standard DHD Series 52 core device so additional software or features such as remote faders can be licensed if or when required. The remote faders option, for example, allows RM1 Pro channels to be controlled from another DHD system or vice versa.”

Also new, DHD’s Routing Web App is compatible with all DHD IP cores (standard XC3, high-capacity XD3 and XS3) and all DHD mixers able to run version 10.4 firmware. DHD IP cores provide the processing power needed for each control console in the company’s product range. These currently comprise the ultra-configurable RX2, the compact price-optimised SX2, ultra-compact desktop DX2, and multitouch tabletop TX2.

“Routing in many studios is an under-the-hood facility which is largely taken for granted until it needs adjustment or major reconfiguration,” says Christoph Gottert, DHD’s international sales manager. “The DHD Routing Web App makes the entire process of assigning and managing incoming sources and output ports easy to view and control.””Routing in many studios is an under-the-hood facility which is largely taken for granted until it needs adjustment or major reconfiguration,” says Christoph Gottert, DHD’s international sales manager. “The DHD Routing Web App makes the entire process of assigning and managing incoming sources and output ports easy to view and control.”

Scheduled for release together with firmware version 10.4 in early 2026, the Routing Web App will expand to six the range of DHD Web Apps which currently embraces the Assist App, Labels App, Snapshot App, System App and Views App. Each can be activated on a licence basis.

Firmware 10.4 adds a range of refinements which expand the operational versatility and third-party product compatibility of DHD equipment.

Also introduced was a new version of the DHD Headphone Box. Connecting via a standard patch cable to one of the headphone ports, this accepts 6.3 or 3.5 mm jacks and has a potentiometer to control the headphone level, plus a GPI to accommodate, for example, a cough-mute button.

Demonstrated ahead of its anticipated Q1 2026 introduction, DHD’s AI-based voice enhancement allows the removal of noise and distortion in live broadcast voice presentations. Developed in cooperation with ai|acoustics, this will be available as an integral element of the DHD XD3 IP core for use with any DHD audio mixing desk. Potential applications include enhancing the audibility of a commentator in a noisy sports stadium or a reporter presenting a live bulletin against a background of city-centre motor traffic. The process can be applied in post-production as well as for live applications, allowing programme editors or newsroom staff to work with content that might previously have been unusable.

Broadcast-related projects completed during the year included a new multi-studio facility with DHD mixers in Amsterdam for Mediahuis Radio. The mixers were supplied by Media Utilities, a long-established audio systems integrator based at Almere. “Time pressure was a significant challenge so we chose to make the five radio studios technically identical with state-of-the-art technology including extensive support for multimedia,” says Tim Blankman, Mediahuis Radio technical manager. “Each of the three production studios has a DHD DX2 mixer that can be used in conjunction with our vocal booths. The vocal booths are also equipped with a DX2 mixer for multifunctional use, allowing programme makers to contribute live or recorded content to the production studios. The DHD mixers are all equipped with lightweight manual faders that enable soft fader starts for fast presentations, combined with the reliability and versatility of digital control. The reactions from our jocks have been very enthusiastic.”

Media Prima, Malaysia’s largest media and entertainment conglomerate, chose DHD SX2 audio production mixers for integration into new broadcast studios on the outskirts of Kuala Lumpur. The project was completed in partnership with VME Broadcast and Stagetec Asia. It included the supply, installation and commissioning of complete audio systems for Media Prima’s TV3 and 8TV television channels. “The project was inspired by the concept of ‘serumah’, or one house, bringing multiple platforms under one roof,” says Mohamad Rezwan Khalil Azmi, Media Prima CTO. “Integration of these systems has significantly improved workflow efficiency and our teams are now better equipped for seamless coordination across departments.” As part of the transition, Stagetec Asia integrated DHD SX2 modular broadcast consoles into the TV3 and 8TV production control suites.

Radio Azzurra FM, northwest Italy, invested in a DHD SX2 audio routing and mixing console for integration into its studio headquarters. The installation formed a central element of a restructuring project by Milan-based BVMedia. “Radio Azzurra selected us to perform the total digitisation and optimisation of their internal technical resources,” says Roberto Zeccara, BV Media senior project manager. “We recommended DHD’s SX2 as the product of excellence for audio management, appreciated for its versatility and speed of setup. Like all DHD mixers, the SX2 is very user-friendly which removes the burden of carrying out time-consuming training. Customisation of the keys plus the versatility of the TFT touchscreens allows presenters to go on air independently and confidently without needing technical support.”

The system is provisioned with all capability tiers needed for real-time and post production, including talkback, clean feeds, configurable buses, loudness monitoring, and routing across multiple studios. At its heart is a DHD XC3 core equipped with Dante and AES67 / Ravenna interfaces, giving full flexibility for IP audio routing, interoperability and future expansion. The control surfaces comprise RX2 and TX2 units configured to meet SRR’s full spectrum of needs in live broadcasting, multitrack production workflows and podcast programming.

RomTek Electronics handled the full scope of the project from equipment supply and acoustic design to installation, configuration and commissioning, delivering a control room and studio facility that blends form and function with hidden acoustics and a modern aesthetic. The RomTek team carefully optimised the mapping of I/O structure and routing architecture so that each production session can operate with minimal latency and maximum reliability, while preserving headroom and signal integrity across the audio chain.

One of the most striking features of the installation is its acoustic treatment using a concept authored by Ion Ungureanu, SSR engineering lead, and integrated by RomTek’s build team. Rather than exposing absorbers and diffusers in visible panels, the acoustic interventions are embedded within the decor, leaving only artistic diffusion elements like subtle reflection control surfaces visible. The room surfaces hide the absorptive and damping layers behind decorative finishes and LED lighting with adjustable colour and intensity. The result is a broadcast control room and local studio that look elegant, warm and contemporary, yet deliver highly controlled reverberation times, low flutter echoes, uniform diffusion and predictable reflection behaviour.

RomTek’s engineers coordinated the cabling, rack layout, grounding scheme, fibre/copper IP connectivity and final configuration, ensuring that the audio network, monitoring and broadcast automation work as a unified system. The DHD elements are integrated into SRR’s wider infrastructure, enabling studio-to-transmitter links, multichannel routing and remote patching.

“This project marks a major leap forward in Romania’s public broadcasting infrastructure,” Ion Ungureanu comments. “The combination of DHD’s modular IP architecture and RomTek’s design knowhow gives us immediate capability and long-term flexibility. We can shift between live programmes, multitrack production and podcast workflows with no change in the central audio path.”

“This project underscores our expertise in delivering turnkey broadcast and production systems, from acoustic and aesthetic design to infrastructure and system commissioning,” adds Corneliu-Cristian Gheorghiu, RomTek business development director for audio|video|TV|film. “The synergy between system topology and hidden acoustic geometry sets a new standard for radio studios in the region. With this installation, SRR is now equipped to meet evolving content demands for on-air and on-line broadcasting, podcast creation and multiformat production, while preserving a clean, elegant studio environment with advanced acoustic performance and visual aesthetics.”

“We have configured the station’s current resources in analog so as to be able to share them throughout Radio Azzurra’s production and transmission structure. Like all DHD mixers, the SX2 is very user-friendly which removes the burden of carrying out time-consuming training. Customisation of the keys plus the versatility of the TFT touch screens allows presenters to go on air independently and confidently without needing technical support.”

“The SX2 console’s automation allows easy operation including immediate recall of surface layout, snapshots and scenes. This gives presenters great security when they are working in self-op mode live-to-air.”

DHD SX2 mixing systems are based on a four-fader central surface plus an optional number of modular six-fader expansion surfaces. All faders are dust-resistant and motorised. Each module can be chained with others to create a standalone mixing desk. Integral display screens allow operators to see exactly how their console is performing both from connectivity and signal level perspectives.

The central module of the SX2 gives access to the most important audio inputs and outputs. A microphone input and headphone output are included and loudspeakers can be connected directly to this unit. Each expansion module allows the addition of a second layer accommodating up to 20 faders. Features can be extended simply by adding optional license codes to the DSP core, allowing extra faders, buses and clean feeds.

At the heart of every DHD mixing control surface are IP cores and concentrators. These connect easily with control modules and input/output boxes via RJ45 ports and standard CAT cable carrying audio, power and control signals (DHD’s APC technology). Gigabit audio and data connections with fibre-optic cables (DHD’s GA technology) can optionally be used to connect cores and concentrators.

“IBC continues to be the biggest and best of Europe’s broadcast-related trade events,” comments Marc Herrmann, DHD managing director. “We experienced good attendance at our stand on all four days of the show, including existing and potential customers from Europe, the Middle East, Asia and South America. We also met with key distribution partners and media system integrators from around the world who appreciate the opportunity to experience our latest technology at first hand.”

“Demand for our products remains strong especially among broadcasters advancing to IP-connected production. At IBC this year we demonstrated our new RM1 Pro ‘Broadcast Anywhere’ system, AI-based voice enhancement and a new Routing Web App for use with our range of IP Audio Cores.” 

“Our established range of audio mixing consoles continues to attract strong interest, all designed to ensure space efficiency and ease of operation. DHD audio consoles are highly compact control surfaces which connect to similarly space-efficient processing cores which can be located near at hand or in a relatively distant control room. Each console module incorporates a high-resolution video display which provides the information required for easy configuration and operation. The RM1 extends this paradigm by allowing broadcasters to connect in from practically any location via IP and participate closely as part of the team in the main studio.”

A complete studio-quality audio production system housed compact robust desktop unit, the RM1 Pro is designed for applications such as remote or onsite broadcast contribution, live news production, web radio and podcasting. Features include AD/DA interfacing, audio preamps, 48 volt phantom power for condenser microphones, audio mixing, EQ and signal dynamics processing. AutoMix mode automatically balances incoming audio channels, conforming background audio to a presettable level and minimising distractions. Settings can be adjusted to enhance individual presentation styles. Features include automatic level control, switching between peak programme metering, EBU R128 loudness metering and customised loudness metering, adjustable profanity delay and flexible sub-mixing.

“We demonstrated AI-based voice enhancement on the stand as highly effective tool for removing unwanted background noise and distortion from live or recorded speech contributions such as sports commentaries or city-centre news reports,” adds Christoph Gottert, DHD international sales manager. “An upcoming new addition to our XD3 IP core processor, it will be available for use with any DHD audio mixing desk. Developed in partnership with ai|acoustics, it also has great potential as a post-production tool to clean content that was previously too noisy to be acceptable for transmission.”

Also introduced at IBC 2025, DHD’s new Routing Web App makes the entire process of assigning and managing incoming sources and output ports easy to view and control. It is compatible with all DHD IP cores (standard XC3, high-capacity XD3 and XS3) and all DHD mixers able to run version 10.4 firmware.

“Our design aim with the RM1 was to bridge the gap between podcast and broadcast,” says Marc Hermann, managing director of DHD. “The new RM1 Pro introduces extra capabilities for professional broadcasters who are working remotely, including tighter connectivity with DHD infrastructure located at a host broadcasting centre. Capable of operating as a voice booth, a workstation, or built into a flight case, the RM1 Pro’s versatility and compact design make it fit anywhere. Core control networking allows the exchange of logic commands with other DHD devices for talkback or on-air signalling. Users also gain access to individual DHD Toolbox configurations plus the ability to create an RM1 Pro user interface tailored to their workflow. RM1 Pro behaves like a standard DHD Series 52 core device so additional software or features such as remote faders can be licensed if or when required. The remote faders option, for example, allows RM1 Pro channels to be controlled from another DHD system or vice versa.”

The RM1 and RM1 Pro are complete studio-quality audio production systems, each housed in a robust desktop unit measuring just 210 x 185 x 44 mm WDH and weighing only 1 kg. Capable of operating from a wall outlet or USB-C linked power source, they are designed for applications such as remote or onsite broadcast contribution, live news production, web radio and podcasting. Features include AD/DA interfacing, audio preamps, 48 volt phantom power for condenser microphones, audio mixing, EQ and signal dynamics processing. AutoMix mode automatically balances incoming audio channels, conforming background audio to a presettable level and minimising distractions. Settings can be adjusted to enhance individual presentation styles.

Connection with external hosts or guests can be established quickly and easily including n-1 mix-minus clean feeds on all return channels to avoid echo and feedback. The control screen can be supplemented by a browser-based interface, allowing operation from a Mac or Windows computer, tablet or a smartphone, or from a Streamdeck via the API. Multichannel recording can be performed to the computer via USB-C.

Also on demonstration at IBC will be latest-generation v1.3 software for the RM1 and RM1 Pro. including the following additions:

• Loudness metering and automatic level control keep signal levels consistent with EBU R128, improving sound quality and ensuring compliance.
• View options allow switching between peak programme metering, EBU R128 loudness metering and customised loudness metering.
• Profanity delay, adjustable up to 100 seconds.
• Auxiliary buses enable two flexible sub-mixes to be used for advanced routing, streaming, separate headphone mixes or external processing.

The RM1 and RM1 Pro both support 48 and 44.1 kHz sampling rates and have an external bit depth of 24 bits. Internal processing is 32 bit, floating. Frequency response is 20 Hz to 20 kHz within -0.05 to + 0.03 dB. Complete specifications can be seen at https://rm1.audio/
