Marantz MODEL M1 Wireless Streaming Amplifier
The Power To Impress
The MODEL M1 is suitable for a wide range of speakers, from bookshelf to floor standing, and in-ceiling or wall-mounted speakers. Its high-power amplification is highly efficient and offers 100W of stereo output with phenomenally low distortion measured at just 0.005% THD via its digital inputs, a figure typically found in amplifiers costing a great deal more. There's also the option to add a subwoofer for a 2.1-channel experience, and the MODEL M1's advanced configuration options allow for full adjustment of both high-pass and low-pass-filter frequencies independently, along with /-15dB of subwoofer level trim.

True Marantz Power
MODEL M1’s 100W per channel of high-quality, low-distortion amplification delivers pristine sound anywhere, while a subwoofer output delivers room-filling scale in larger spaces.

High Resolution Digital Direct
However you choose to stream your high-resolution music, MODEL M1 has you covered, with support for HEOS, AirPlay2, Bluetooth, Spotify Connect, and more.

Marantz Multi-Room
The expansive feature set yet diminutive size of M1 makes it the ideal partner for multi-room listening.

Marantz Musical Digital Filtering
MMDF is a unique and sophisticated digital filtering technology that reveals the natural detail and tonality in sound.

TV Sound: Marantz Quality, Soundbar Simplicity
Unveil superb sound from movies and TV programs with MODEL M1 using HDMI eARC and onboard Dolby Digital processing.

Welcome To The Digital Domain
The MODEL M1's powerful amplification is complemented by full high-resolution music support. The MODEL M1 supports the full high-resolution music experience over streamed services, your network or even USB, including 24-bit/192kHz PCM support as well as DSD. To ensure these high-resolution signals are delivered in the best possible quality, MODEL M1 operates in the digital domain from end to end. This simplifies the signal flow and eliminates errors caused by the inexpensive DACs typically found in traditional hi-fi. It also means all sources leverage the powerful DSP technologies built in, including Marantz Music Digital Filtering (MMDF), first developed for the brand’s reference-grade audiophile CD players and designed to ensure the characteristic warmth and musicality of any Marantz product.

HEOS Built-in
With HEOS® Built-in technology, use the HEOS app to access all the music services available on the HEOS platform. Also with other connected HEO enabled devices you can enjoy your favourite music in any room of your home for a wireless, whole-home audio experience. Play the same song in every room or select a different song for each connected room - the choice is yours.
In addition to HEOS, MODEL M1 supports Bluetooth, Spotify Connect and AirPlay2 (as well as soon-to-be-released updates for TIDAL and Roon Ready support!), ensuring wide- ranging wireless music streaming for almost any content you may wish to access, and from almost any device. You can even play audio from a locally connected USB-A drive, making this compact product a powerhouse of connected, streamed and network-served high-resolution audio.

The Heartbeat Of Your Home
When you’re not listening to music, the MODEL M1 is a perfect alternative to a soundbar or to an AV receiver for high-quality TV watching. Its included eARC HDMI input means simple one-remote control over system volume levels and power management using your TV’s supplied handset.
The onboard Dolby Digital decoding supports a range of useful adjustment functions for an optimised experience whatever and whenever you are watching. That includes a Dialogue Enhancer option to make voices more easily discernible when listening at low volume levels, plus a Virtual mode that utilises Dolby processing to generate a large, three-dimensional sound field from stereo-only content - perfect for homes where a larger full-sized surround sound system simply isn’t an option.
