RME has announced the introduction of the M-32 Pro II Series that includes four new audio networking devices, each unit consisting of a specific combination of Dante, AVB, and MADI and offering 32 channels of A/D or D/A conversion. Models include:
— M32 AD Pro II AVB (128 x 128) + MADI (128 x 128) + 32 channel A/D converter
— M32 DA Pro II AVB (128 x 128) + MADI (128 x 128) + 32 channel D/A converter
— M32 AD Pro II-D Dante (64 x 64) + MADI (128 x 128) + 32 channel A/D converter
— M32 DA Pro II-D Dante (64 x 64) + MADI (128 x 128) + 32 channel A/D converter
Designed for applications including studios, playback rigs, immersive audio, live sound, and audio labs, the M-32 Pro II is engineered for high-quality analog conversion as well as digital audio network conversion that incorporate either Dante, MADI, or Milan-compatible AVB. All units provided balanced signal routing and are stated to offer 120 dB(A) dynamic range with low latency.
While the M-32 AD Pro II series offers the same analog performance as its predecessor, the DA converter has improved THD+N to -111 dB. Optimization of the impulse response at high sampling rates further refines the digital to analog conversion process.
The series offers individual channel switching to different studio levels while maintaining full converter resolution. In addition, it provides the SMPTE-recommended +24 dBu at 0 dBFS, allowing it to handle louder analog signals.
The frequently requested Dante connectivity has been integrated by RME directly into the M-32 Pro II-D hardware. It allows connection to other audio devices via standard network switches. Users can connect up to 64 audio channels from a computer directly to the M-32 Pro II-D’s analog and digital inputs and outputs using the Dante Virtual Soundcard.
The AVB models transmit and receive up to 128 channels at 48 kHz (96@96k, 64@192k) with a predefined fixed latency. Each device also shares its status and configurable options across the network using ATDECC (IEEE 1722.1), enabling integration into deterministic networks.
A second network port has been added to allow redundant operation. The Dante model includes a network switch mode to connect multiple devices together via the secnd port. In addition to coaxial word clock and MADI ports, an optical MADI port can be upgraded with an optional SFP module for redundancy or applications requiring high channel counts at high sample rates. Channels from both MADI ports can be individually routed to and from AVB/Dante.
The high-resolution 2-inch display with rotary encoder provides status feedback and allows access to settings directly at the unit, including clock configuration, preset management, single channel routing, redundant power supply monitoring and more.
