Leipzig, Germany, 3 December 2025: DHD audio reports a successful 2025 with new additions to its range of broadcast-quality audio production, post-production and routing equipment.
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.”
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.”
Radio Marca in Spain chose DHD audio mixers and routing as the heart of recently expanded production facilities at its Madrid headquarters. Supervised by Agrupación de Servicios y Productos de Audio (ASPA), the project encompassed planning and equipping a main radio studio, two secondary studios, three audio production booths and the master control room. The system recommended and installed by ASPA’s project management team includes six DHD digital mixing consoles plus a complete DHD routing matrix. RX2 mixers with 18 physical faders have been integrated into the main and secondary studios plus DX2 consoles with four physical faders in the audio production booths. Both models allow layered operation by extending the number of channels of each console. The new MCR is equipped with a complete routing system centred on a DHD XD3 core digital signal processor.
Radio Televisyen Malaysia (RTM) Sarawak, the central regional division of Malaysia’s state broadcast network, specified DHD audio mixing consoles and digital signal processing cores in a major upgrade to its studios in Kuching. System design, installation and commissioning were coordinated by Stagetec Asia. A key part of the project was the integration of six DHD SX2 consoles plus primary and auxiliary XC2 cores. “RTM’s trust and satisfaction in its partnership with Stagetec Asia are grounded in a robust collaboration initiated in 2005, a bond further highlighted by the recent undertaking of an extensive broadcast project at Angkasapuri Kota Media,” adds Advon Tan, Stagec Asia managing director. “Our track record in executing complex audio infrastructure projects was instrumental in securing this project which equips RTM Sarawak for highly efficient broadcast production, combining operational versatility with high signal quality.”
