Marantz Stereo 70s

Home Cinema from Only Two Channels
STEREO 70s merges the flexibility and features found in our CINEMA Series AVRs into a slim and simple 2 channel receiver. 8K HDMI plus ARC facilitates connection of smart TVs, game consoles and streaming systems. On screen display uses your TV screen to assist with setup. Support for up to 2 subwoofers means plenty of deep bass even when using small bookshelf speakers.

High Resolution Audio
Carefully engineered with specially chosen components, STEREO 70s unveils the natural immersiveness and power of sound. Crystal clear digital decoding of up to 192 kHz 24-bit audio and DSD opens a new world of high resolution music with depth, breadth, and clarity not available with lossy files.

Slim and Elegant
Marantz design is timelessly elegant—an expression of the musical soundscapes the products create. Our philosophy of balance and symmetry is evident in our sound and our designs. Meticulously engineered in a compact chassis, STEREO 70s fits where standard equipment cannot.

HEOS® Built-in Multi-Room Streaming
HEOS® Built-in technology lets you enjoy your favorite 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.
