M17 V2i SURROUND SOUND PREAMP PROCESSOR The NAD M17 V2i Surround Sound Preamp Processor is designed to bring high-performance audio principles to multi-channel systems. Combining advanced surround processing, high-resolution streaming, and room correction within a modular platform, it allows both film and music to be reproduced with clarity and balance. With support for formats such as Dolby Atmos and DTS:X, alongside BluOS streaming and Dirac Live Room Correction, the M17 V2i maintains a consistent, natural presentation across all channels, making it a flexible foundation for systems that prioritise sound quality as much as capability. KEY FEATURES Modular Design Construction (MDC) supports hardware upgrades as formats and technologies evolve. Dirac Live® Pro room correction for improved clarity, balance, and low-frequency accuracy Dolby Atmos® and DTS:X™ support for multi-dimensional surround sound 11.1 balanced XLR outputs for low-noise, high-performance multi-channel systems BluOS® streaming with support for high-resolution audio and multi-room playback 4K UHD video pass-through with HDR and HDCP support Smart integration with 12V triggers and RS-232 for control systems Flexible surround and stereo performance across multiple configurations PRODUCT STORY SURROUND SOUND WITH DEFINITION AND BALANCE The M17 V2i processes multi-channel audio with a focus on separation and balance across all channels. Dialogue remains clear and centred, while effects and ambient details are placed accurately within the listening space. Whether watching films or listening to multi-channel music, each element is presented with clear positioning, allowing you to enjoy your favourite content without distraction. STREAMING AND SOURCE FLEXIBILITY With BluOS built in, the M17 V2i provides access to high-resolution streaming services, internet radio, and local music libraries through the BluOS Controller App. It supports both stereo and multi-channel listening, allowing the system to adapt to different types of content. Combined with a wide range of digital and analogue inputs, it integrates easily into modern systems. BUILT TO EVOLVE NAD’s Modular Design Construction allows the M17 V2i to remain relevant as formats and technologies change. Instead of replacing the entire unit, key modules can be upgraded over time. This approach extends the lifespan of the product while maintaining compatibility with new formats and system requirements. The BluOS Advantage BluOS elevates the M17 V2i beyond a traditional AV processor, providing access to thousands of internet radio stations and leading music services including TIDAL, Spotify, and Amazon Music. Combined with MQA support, BluOS delivers high-resolution audio and effortless multi-room control.
