Description
RDL RU-RN40 - Dante/AES67 network interface with 4 XLR microphone/line inputs and DSP
The RDL RU-RN40 from the RACK-UP series is a professional audio interface that converts 4 analog microphone or line inputs into 4 Dante/AES67 network channels. The device is designed for commercial and industrial installations - it can be mounted in rack cabinets, technical rooms, at conference tables, on shelves, and on mounting walls. Each Dante/AES67 output path is powered by a built-in 4-channel mixer, which receives all 4 inputs of the device. Independent level control in the mixers and programmable DSP filters make the RU-RN40 much more versatile than a typical format converter and can serve as an audio mixer and distribution amplifier. The inputs support line sources and dynamic and condenser microphones - offering a preamplifier with gain up to 60dB, individually switchable P48 phantom power, and a compressor/limiter. An ultra-low latency of 1ms (analog-to-digital) and A/D conversion at 24-bit resolution with a sampling rate of 48kHz or 96kHz ensure high sound quality. Each input is available on an XLR socket or detachable terminal block, with a nominal line level of +4dBu symmetrically for -18dBFS. The interface can be powered via PoE (Power over Ethernet) or from an external 24V DC power supply, available separately. In factory configuration, the inputs operate at line level, with phantom power and compressor/limiter turned off, and each channel is sent unchanged to its assigned Dante/AES67 output.
Functionality
- conversion of 4 microphone or line inputs to 4 Dante/AES67 channels in factory configuration
- 4x4 mixing matrix with DSP filters - flexible system design
- 4-channel mixer on each Dante/AES67 output - level adjustment for each source from full level (unity) to off (OFF)
- ability to create mixes, e.g., mono sum from stereo source
- audio mixer and/or distribution amplifier function
- input gain adjustment from 0 to 60dB in 3.3dB steps
- P48 phantom power individually switchable for each input or automatically depending on gain
- switchable compressor/limiter on each analog input
- 1 DSP filter for each audio input
- 3 DSP filters for each Dante/AES67 output
- filter type selection: none (signal pass), high-pass, low-pass, shelving high/low, notch (boost/cut)
- all DSP filters fully programmable
- Dante/AES67 output adjustment in 1dB steps from 0 to -63dB, then OFF
- remote volume control using compatible RDL controllers, e.g., D-NMC1R and D-NLC1R (available separately)
- configuration of all parameters in RDL CONSOLE software (version 3.0 or newer)
