Marantz Model 40n Integrated Amplifier

An Integrated Amp for the Digital Age with Luscious Analog Sound

Marantz has reimagined the integrated amplifier for the digital age while preserving a luxurious analog feel and sound. The MODEL 40n Integrated Amp with Streaming Built-in is a masterpiece of audio architecture. Created with passion and extraordinary attention to detail, every element brings you closer to the music you love.

A full complement of analog and digital inputs plus built-in streaming and HDMI make listening enjoyable and easy, regardless of source. Stream from Spotify, Pandora, Tidal, and more or enjoy your own music file libraries. Works with Alexa, Google, and Siri. Create a multiroom musical experience with the MODEL 40n as your home’s music hub. HDMI ARC (Audio Return Channel) adds uncommon flexibility to this stereo amplifier by enabling TV sound through your stereo.

The MODEL 40n easily fills your space with beautiful sound. Rated output power is 70 watts per channel at 8 ohms and 100 watts per channel at 4 ohms. All functions can be controlled with the free HEOS® app for Apple and Android, or use the included wireless remote.

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 – along with 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, but it 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

Marantz puts your sound preferences at your fingertips. Adjust bass and treble to suit your tastes or bypass the tone controls 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 the 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.
