Designed for modern broadcast, live production, and critical audio environments, the Sonifex RM-X-64-DNT reference monitor range delivers uncompromising flexibility and reliability in a compact 1RU form factor. As standard, the unit features seamless Dante AoIP and MADI integration, intuitive control, fast source selection, and full redundancy, serving as the monitoring backbone of any professional workflow.
At its core, the unit supports up to 128 channels of simultaneous monitoring, combining 64 channels of Dante AoIP and 64 channels of MADI via BNC connections. With seamless integration into AoIP-enabled networks, the units fit effortlessly into complex, networked audio infrastructures. Two modular expansion slots further enhance flexibility, enabling support for additional sources in any combination to suit specific workflow requirements. Expansion options include 8-channel analog inputs, 8 stereo digital inputs, or up to 64 channels of de-embedded audio from 12G-SDI, allowing the system to be precisely tailored to individual applications. Fully configured with both expansion slots populated by 12G-SDI cards, this device can support monitoring of up to 256 channels.
Control and usability are central to the unit's design. A vibrant 6.6" color touchscreen provides fast, intuitive access to metering and system configuration, complemented by rotary encoders for accurate adjustment of key parameters. The display supports up to 64 channels of visual monitoring per source, with a streamlined interface that allows you to swipe left or right to move quickly between sources. Individual channel selection via the rotary encoder ensures precise control when building monitor mixes from any source, with a press-and-hold function for soloing.
It offers comprehensive metering compatible with multiple PPM standards, including BBC, EBU, DIN, and Nordic scales. Meter ballistics are fully configurable, featuring both Type I, Type II and Type II slow quasi-peak responses. Fast attack times and carefully controlled decay ensure precise peak detection while maintaining clear, operator-friendly readability.
The units are equally capable in their output performance. Integrated front-panel speakers with machined grilles deliver accurate acoustics, with ported enclosures maximising performance within the compact 1U form factor. A stereo analog/digital output on professional Neutrik XLR connectors allows connection to local or remote speaker systems, while front-panel ¼" and 3.5mm headphone outputs provide convenient access for detailed listening, particularly in noisy environments.
A built-in front-panel microphone provides convenient talkback routing over the AoIP network, with mic control available directly on the unit, via the web GUI, or through Ember+.
Full web GUI access enables system management from anywhere, making the units ideally suited to OB trucks, control rooms, and distributed facilities. Connectivity and integration have been carefully considered, with dual network ports that can operate in switched or redundant modes, as well as dual SFP ports for fibre connectivity and additional redundancy options.
To summarise, combining reference-quality monitoring, extensive input flexibility, and powerful AoIP integration, the RM-X-64-DNT provides a future-proof solution for professional audio environments. With integrated speakers, headphone amplification, external outputs, and robust redundancy throughout, these units deliver the control, precision, and confidence required in today's increasingly networked workflows.
