A "Pro II" Evolution Designed for Modern Studios and Networked Audio
The M-32 Pro II series was developed to meet the demands of environments where conversion must never be a weak link: professional studios, immersive installations, live sound reinforcement, as well as technical and industrial applications. This generation emphasizes improved specifications (notably very low distortion values), intelligent routing, and more straightforward ergonomics to best utilize hybrid audio setups (analog, MADI, audio network).
With its 32 channels and comprehensive digital I/O, the M-32 Pro II positions itself as a "core" converter: centralizing analog sources, securing the clock, and bridging broadcast and audio distribution infrastructures.
Who Is This Converter For, and In Which Applications Does It Make a Difference?
This AD converter targets engineers and integrators who need to digitize a large number of signals without compromise: multi-mic recordings, console returns, preamp racks, summing outputs, stems, or inputs of a broadcast mixing system. The 19" / 1U format allows rack densification while maintaining clear level monitoring.
In the studio, it becomes a dedicated conversion interface to feed an audio network or a MADI backbone, while maintaining a wide headroom thanks to the +24 dBu. In live and installation contexts, the presence of MADI I/O, Word Clock, and RJ45 network facilitates integration into existing architectures, including when distributing audio over long distances and maintaining reliable synchronization.
Features, Ergonomics, and Connectivity: A "Pro" Approach Without Wasting Time
Conversion and Headroom: Precision Without Fragility
The M-32 Pro II aims for transparent conversion with 24-bit / 192 kHz resolution, a 120 dBA signal-to-noise ratio, and a fully balanced circuit. Practically, this results in a stable image, usable dynamics, and capture that respects transients, while remaining comfortable at the high levels often encountered in professional environments.
Level Monitoring: Immediate Reading, Safer Decisions
The large backlit tricolor channel display with peak / RMS indication provides quick reading, useful both for calibration and production safety. The 2" screen combined with the rotary knob offers direct access to essential settings without relying on a computer for routine operations.
Synchronization and Operational Reliability
In multi-device environments, sync is critical. The SyncCheck and ICC functions are designed to secure operation and speed up diagnostics during clock changes, patching, or configuration switching. The 5 preset memories allow quick recall of consistent settings (studio session, live mode, installation, maintenance), limiting errors and repetitive handling.
Routing, Labeling, and Rack Integration
Intelligent channel routing helps organize dense systems, while channel labeling fields with a magnetic cover simplify identification in racks, both in studios and on tour. With professional connectivity (Sub-D, BNC, RJ45) and a 1U chassis, this converter naturally integrates at the heart of a conversion, stage, or control room rack.
