Manufacturers Details:

Extraordinarily Simple — Just Add Speakers

The Marantz MODEL 40n provides listeners with wonderfully rich and satisfying sound which is equal to or better than what audiophiles have sought after for years with stacks of complicated equipment. Such performance is now available in a single unit which can be connected to speakers of the listener’s choice.  Listening to music is effortless thanks to built-in access to Spotify Connect, Amazon Music, Tidal, TuneIn internet radio and many more. The MODEL 40n also provides access to personal file libraries, up to PCM 192kHz / 24 bit as well as DSD up to 5.6 MHz. Wireless connectivity options include Apple AirPlay 2, Bluetooth and Wi-Fi with HEOS Built-In®.

Extensive Connectivity — HDMI, Phono, and More

The MODEL 40n offers a full complement of analogue and digital inputs to accommodate any source, including Marantz Musical Phono EQ—a moving magnet phono stage for vinyl playback. Unusually for products in this category, the MODEL 40n features an HDMI ARC (Audio Return Channel) input making audio playback from a TV possible. TVs with built-in access to movie and streaming services sound incredible when used with the MODEL 40n. A dedicated subwoofer output with crossover adjustments enables users to optimize bass response for any listening room. Enthusiasts will enjoy all these options through exceptional Marantz analogue amplification that delivers spacious, dynamic sound with unmatched levels of detail and clarity.
Streaming Together or Separate – Whole Home Audio

The MODEL 40n has been designed to work as the primary hub for one or multiple rooms. With HEOS® Built-in technology, the entire family can enjoy their favourite music in any room for a wireless, whole-home experience. Play the same song in every room to create a festive mood or select different songs for each connected room by adding HEOS-capable speakers throughout the home. As smart as it is, it not only works for streaming services, but any input on the MODEL 40n including phono.
Featuring advanced Wi-Fi technology, the MODEL 40n facilitates wireless streaming via Wi-Fi and Bluetooth that is stable even in congested urban settings. For an intuitive user experience, the MODEL 40n comes with a remote control, and conveniently works with Siri, Alexa and Google voice command. Availability of the service may vary per country.
Elevated Amplification

A new 70 watt per channel (8Ω) Class A/B amplifier stage has been developed that exceeds the performance of earlier models with similar power ratings. A larger power supply transformer, four output transistors per channel, heavy copper bus bars, and very short power pathways lower internal impedance and deliver high instant current capability making the MODEL 40n highly dynamic and an excellent match for even difficult to drive loudspeakers.
Expertly Engineered and Sound Master Tuned

For the MODEL 40n, Marantz Sound Masters utilized the finest components to maximize performance. The MODEL 40n leverages the company’s proprietary Hyper-Dynamic Amplifier Modules (HDAMs) that deliver the most musical sound possible—from precise bass transients to smooth, balanced midrange and high frequencies from any connected loudspeaker. Leveraging curated discrete surface mount components and the shortest possible signal paths, the HDAMs inside the MODEL 40n has been engineered to provide uncompromised listening pleasure.

Engineered With Care: 

Multiroom streaming with HEOS Built-in

Effortlessly connect via Bluetooth, Apple AirPlay 2, or directly from the HEOS app to play all your favorites from hundreds of streaming services.

High-Resolution Digital Streaming Built-In

MODEL 40n is for those whose music collection is infinite and online. Connect to your network with Wi-Fi or ethernet. With HEOS® Built-in, you won’t need extra equipment to stream your favorite tunes. MODEL 40n supports Spotify, AirPlay 2, Apple Music, Bluetooth, Tidal, TuneIn, and more services—plus, playback of your own collection via USB-A input or on compatible home servers.

The Marantz Musical Phono EQ

The joy of vinyl playback is both audible and tactile yet requires highly specialized electronics for high performance. The Marantz Musical Phono EQ is built in so you can connect a turntable with MM cartridge directly to MODEL 40n. You’ll enjoy your favorite records and discover new ones, all without the burden of additional electronics.

Precise Tone Control

Your sound preferences at your fingertips. Adjust bass and treble to suit your sound or bypass for the purest sound possible.

Luxurious Look and Feel

MODEL 40n follows a long line of historic Marantz pieces notable for their exquisite design. Every aspect is considered—from premium materials, symmetry, classic porthole display, and even smooth operation of the volume control. Your stereo doesn’t need to look like lab equipment. Marantz MODEL 40n begs to be heard, seen, and touched.

Hyper Dynamic Amplifier Modules

To preserve the detail, nuance, and essence of the music you love, Marantz developed HDAM (Hyper Dynamic Amplifier Modules) which are superior in their speed and response to off-the-shelf modules found in other products. MODEL 40n leverages this unique Marantz innovation to ensure whatever you’re listening to is always the most musical.

Subwoofer Output

Deep bass is a visceral and exciting sensation. When partnered with equally excellent speakers, MODEL 40n produces impressive bass. If you want more, add a subwoofer using the dedicated subwoofer output and dial in the low-frequency crossover settings and level for precise integration with your main loudspeakers.
