With the M-32 AD and M-32 DA, RME presented two independent 32-channel converters in 2010, which quickly became the industry standard thanks to their high quality, reliability, and a number of channels. Since then, not only the converter technology but also the requirements of pro audio users have evolved in all kinds of areas – professional studios, immersive sound installations, live sound systems and even applications in the industrial sector requiring high analog channel counts.
Solutions for modern productions
Redundant power supplies, more compact housings, network functionality – these and other wishes were brought to us by our customers for a revised 32-channel converter series. With the new M-32 DA Pro and M-32 AD Pro, RME meets the diverse requirements of current productions and installations.
Reference in analog and digital
Based on state-of-the-art, high-resolution converter components and a fully balanced analog circuit design, the new M series offers a signal-to-noise ratio of 120 dB(A) with extremely low THD values, which places the converters in the reference class.
Linear and transparent
Each of the 32 channels enables AD/DA conversion with up to 192 kHz sampling frequency. The internal filters are based on the recently introduced ADI-2 Pro reference converter and allow a completely linear frequency response (up to 0 Hz at the output).
AVB – The future of network signal transmission
In addition to the two, fully equipped MADI I/Os including separate signal routing, the new M-32 DA Pro and M-32 AD Pro feature an AVB interface based on the open network standards IEEE 802.1 and 1722.1, enabling transmission of the 32 analog channels at a maximum 192 kHz sampling rate via a single Ethernet cable. Combined with external AVB switches, the new M-Series converters can be quickly, easily and reliably integrated into more complex network structures thanks to the comprehensive time-synchronous signal processing of the AVB protocol.
The open AVDECC 1722.1 control protocol as part of AVB allows users to use external controllers from different manufacturers to control almost all device functions. In addition, a web interface and a JSON API are available – both via the network connection and the integrated USB port.
For maximum compatibility with a variety of analog hardware, the individual channels of the M-32 AD Pro and M-32 DA Pro can be operated with different line levels – each with full resolution of the converters. Besides +19 dBu and +13 dBu, the new M-Series is one of the few solutions available on the market that also allows working with the SMPTE® recommendation of +24 dBu at 0 dBFS.
Everything at a glance
The combination of level displays and channel labeling fields conveys a familiar analog feeling but proves to be an almost indispensable advantage in daily practice. Using the supplied transparent papers, users can create individual channel labels and securely affix them behind a magnetic cover. This always gives a comprehensive overview of analog channel assignments.
In digital audio, the clock frequency is an essential factor, as it creates the correlation between the audio bits and the time reference. Unfortunately, the clock frequency is not always as stable as desired. The M-32 Pro offers full SteadyClock FS performance for the lowest jitter and highest jitter immunity. Excellent performance in all clock modes and High-Quality Analog Conversion to hear your mix as it is. Digital format conversion in RME products are done without any loss or degradation, and SteadyClock FS ensures your sonic image will never experience degradation. This helps to optimize recordings and mixes because the soundstage has more depth and clarity.
