The RME M-32 AD Pro II AVB + MADI 32-Channel A/D Converter is designed to meet the demanding requirements of professional studios, immersive sound installations, live sound systems, and industrial applications that need a reliable solution for reference-class A/D conversion with high-end MILAN-compatible AVB and MADI network audio processing.
While it offers the same outstanding analog performance as its predecessor (with high-resolution converter components and fully balanced signal routing), the M-32 AD Pro II delivers an extremely low THD of -111 dB and optimizes the impulse response at sampling rates of 88.2 kHz and higher to minimize ringing artifacts in the conversion process and achieve 120 dB(A) of dynamic range with very low latencies.
M-32 AD Pro II AVB + MADI Features
- 32-channel reference-quality A/D converter, fully symmetrical design
- 32 analog inputs (25-pin D-sub, up to +24 dBu)
- 2 MADI I/O (via separately available optical SFP and coaxial BNC, up to 128 channels)
- 2 RJ45 1 GigE Milan-compatible AVB ports, four streams with 4/8/12/16 channel each
- MIDI I/O for legacy MIDI remote
- Wordclock I/O (BNC)
- USB 2.0 for remote control
- SyncCheck and ICC detect when a clock source is not in sync and fall back to other available signals
- MADI Auto-Input provides seamless redundancy
- 2" display with control knob for full device control
- Large tricolor backlit channel indicators with peak/RMS metering
- Magnetic cover with customizable channel labels
- 15 preset storage, firmware-upgrade persistent
- Lock (optional code) and dark mode
- Internal routing of up to 224x192 channels in 4 channel blocks (32 x analog, 64 x MADI optical, 64 x MADI coaxial, and 64 x AVB)
- Remote control via HTTP, JSON, IEEE 1722.1 AVDECC, MIDI over MADI and optional MIDI
- 2 monitored, fully redundant internal PSUs
- Compact 1 RU, 19" enclosure
Plug and Play—Rapid User Interaction
- The high-resolution 2" display with rotary encoder provides comprehensive status feedback at a glance and allows access to settings directly at the unit—including clock configuration, preset management, single-channel routing, redundant power supply monitoring, and many more functions.
- RME AVB devices can be reached over network (including wirelessly over Wi-Fi) and USB for convenient remote access, allowing the rapid creation of gain groups and clock configuration.
- The integrated routing matrix allows single-channel routing across all analog and digital I/O.
- Tricolor, backlit channel label fields offer an advantage in fixed installations. Using the included transparent sheets, users can create individual channel labels and securely affix them behind a magnetic cover where they are illuminated depending on signal level. This provides a comprehensive overview of analog channel assignments and signal flow.
Analog Line-Level Compatibility
- For maximum compatibility with a variety of analog hardware, the individual channels of the M-32 AD Pro II can be operated with different line levels—each with converters at full resolution.
- Besides +19 and +13 dBu, the unit is also capable of working with the SMPTE recommendation of +24 dBu at 0 dBFS.
AVB Audio Networking with Two Fully Redundant Network Ports
- The M-32 AD Pro II features two fully redundant MILAN-compatible AVB network ports.
- The AVB interface is 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 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.
- Up to 128 audio channels at 48 kHz (96 at 96 kHz, 64 at 192 kHz) can be sent and received over AVB in total across all streams.
- Any signal reaching the M-32 Pro II can be routed and streamed over a network with fixed latency and guaranteed bandwidth—no switch configuration is required.
Redundant Coaxial and Optical MADI Ports
- The M-32 AD Pro II's two coaxial and optical MADI ports are ideal 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.
