Radio Romania Upgrades To DHD RX2 And TX2 Audio Mixing Consoles

The Romanian Radio Broadcasting Company (SRR) has commissioned a new state-of-the-art radio production and broadcast facility centred on a DHD RX2 and TX2 console system delivered and integrated by DHD's Romanian partner RomTek Electronics.

The newly equipped studios will support SRR's production, broadcast and podcast operations, advancing the technical infrastructure at the network's Bucharest headquarters with modular IP-based audio architecture and a seamlessly integrated acoustic design.

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."

DHD RX2 mixers are based on central and fader modules which can be combined to accommodate up to 96 faders. Each module has a 10.1 inch touchscreen which gives access to main control and channel settings, metering and system snapshots. Each RX2 fader module includes six dust-protected 100 mm track-length motorised faders. Every fader channel is augmented by a rotary encoder and two pushbuttons. The rotary encoder can be assigned to control gain settings, auxiliary sends, EQ parameters and dynamics. The pushbuttons are assignable to functions such as on/off, prefader listen, layer or talk.

DHD TX2 ultra-compact audio production mixers can be deployed standalone or as an easy way to expand any DHD system. The TX2’s forward-sloping panel includes a 10.1 inch capacitive touchscreen IPS display, two assignable potentiometers and six silent multicolour hardware buttons, allowing fully professional audio mixing. The number and size of faders can be configured, buttons can be assigned with the required functions and peak meters can be set to show specific channel signal levels. The TX2 can be integrated with DHD XC3, XS3 or XD3 cores in isolation or as part of a larger mixing system and does not require a PC for operation.
