The Stereo 70s combines Marantz's signature sound signature with a slim design and excellent everyday usability.

High-performance stereo power amplifiers

Inside the Stereo 70s are discrete power amplifiers that deliver stable and controlled performance for demanding loudspeakers. The amplifier is designed for precise, balanced reproduction and offers ample power reserves for dynamic musical passages. Voices and instruments are presented clearly and spatially, while the bass remains controlled and defined.

HDMI integration for modern media

A key feature of the Stereo 70s is its comprehensive HDMI connectivity. Multiple HDMI inputs and an HDMI output with eARC enable seamless integration of TVs, streaming boxes, and game consoles. This makes the Stereo 70s ideal as the central hub for a high-quality stereo setup in the living room, where both music and TV audio are played back through the same speakers.

Network and streaming functions

Thanks to integrated network technology, the Stereo 70s supports modern music streaming via LAN or WLAN. Streaming services, internet radio, and music from your home network can be conveniently controlled via the HEOS platform. Common wireless standards are also supported, allowing music to be played directly from mobile devices. High-resolution audio formats are processed internally and precisely transmitted to the power amplifiers.

Digital and analog connectivity options

In addition to HDMI, the Stereo 70s offers a wide selection of digital and analog inputs. These include optical and coaxial digital inputs as well as classic RCA inputs. For vinyl enthusiasts, an integrated phono preamplifier for MM cartridges is available. Two subwoofer outputs allow the system to be extended in the low-frequency range without compromising the stereo imaging.

Housing, operation and design

The Stereo 70s's housing is intentionally slim, making it suitable for compact furniture or lowboards. The front panel design is based on classic Marantz aesthetics, featuring clean lines and a premium feel. Operation is via the central display, the included remote control, or an app, allowing for flexible everyday control.

Area of application

The Marantz Stereo 70s is ideal for anyone looking for a modern stereo system with TV connectivity, streaming capabilities, and classic hi-fi quality. It is equally suitable for music streaming, vinyl playback, and high-quality TV sound, offering a balanced combination of sound quality, connectivity, and ease of use.
