Marantz Stereo 70S stereo AV network receiver

Marantz STEREO 70s is a compact, 75-watt-per-channel stereo amplifier and AV receiver with 8K video technologies and built-in HEOS streaming; it has a phono input and FM/DAB+ radio tuner, supports Bluetooth, Wi-Fi and AirPlay 2 capabilities, and is compatible with Amazon Alexa voice control.

It naturally supports high-resolution audio, with the ability to decode ALAC, FLAC and WAV lossless files up to 24 bit/192 kHz, as well as 2.8 MHz and 5.6 MHz DSD tracks via the rear panel USB port and network sources.

STEREO 70s is Roon Tested; therefore, it offers the most from your digital music library with searchable and navigable information about your favorite artists and songs.

This discrete stereo amplifier produces clear, detailed, warm, spacious and dynamic sound from any source.While simple and convenient as a two-channel stereo system, STEREO 70s features six HDMI inputs, three of which are 8K, and is compatible with a wide variety of video streamers, gaming systems and TVs.
And with the dual subwoofer output, the home theater listening experience becomes even more immersive.

Meticulously designed in a compact chassis, STEREO 70s can be installed where ordinary amplifiers cannot be placed.

Marantz’s optimized class A/B amplification features discrete printed circuits called Hyper Dynamic Amplifier Modules (HDAMs), with short, specular left and right signal paths, for better results in response speed and noise level.

Pre-Amp Mode

STEREO 70s can function as a perfect slim pre-amplifier with the latest HDMI connectivity. Preamp mode provides a cleaner signal path and greater tolerance in clipping level by disconnecting internal amplifiers. The receiver has 2.2-channel pre-outs.
Multi-zone audio

By connecting other HEOS-enabled devices to your home network, you can play the same audio in multiple rooms, or have them play independently. STEREO 70s also has ‘Zone 2’ audio output, so you can connect it to a power amplifier for another room. Or use the ‘A+B’ feature to drive a second pair of speakers in another room, directly from STEREO 70s.

Headphone output
Connect wired headphones via the front panel output or use the Bluetooth output to connect to your wireless headphones.

Maximum Ease of Use
The included remote control (backlit) features four buttons with Smart Select function to store favorite or frequently used settings and easily recall them. The Marantz Setup Assistant, with its eye-catching HD interface, guides the user through installation, helping them adjust crucial settings for the best possible audio quality, whichever configuration is chosen.
