A versatile integrated amp to build your entire system around
The Marantz Model 40n is a do-it-all centerpiece you can build an excellent two-channel sound system around. It's a classic integrated amp at heart, with 70 watts per channel to drive your speakers, plus a wealth of digital and analog connections.
It's also a state-of-the-art network player that gives you access to popular streaming apps, internet radio, and Apple AirPlay 2. An excellent built-in DAC (digital-to-analog converter) plays back digital files with up to 24-bit/192kHz resolution. And the amp is compatible with voice control via optional Google Assistant and Amazon Alexa devices, for the ultimate in convenience.
Inputs and outputs
I love the convenience of streaming, but I always have components I want to connect to an integrated amp. The Model 40n offers three standard line-level RCA audio inputs, plus a discrete phono stage for connecting a turntable with a moving magnet cartridge. A variety of digital sources can be connected, too — there are individual coaxial digital and optical digital inputs, plus a Type-A USB port, an Ethernet port, and an HDMI ARC port for boosting your TV sound.
The 40n has you covered on outputs, too. There's a pair of binding posts for connecting speakers, and a mono subwoofer output. There are also stereo RCA audio outputs for recording and a 1/4" headphone jack for private listening. If you want to use the 40n as part of your surround sound system, a dedicated stereo "power amp" input lets you feed a signal from a home theater receiver or preamp to drive your front left and right speakers.
Streamline your music with HEOS
HEOS Built-in technology lets you access all of your music — from your personal library, internet radio, and popular subscription services like Apple Music, Spotify®, TIDAL, and more.
And HEOS also lets you build a wireless multi-room audio system. Stream music to HEOS wireless speakers and components in different rooms, and control each room's speakers independently with the free HEOS app. The app lets you control playback, browse music sources, and select which rooms you want to use. Play the same music throughout your home or listen to something different in each room.
