MARANTZ MM7055 Amplifier multichannel

The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.  This is "real world” power, too, measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion.  Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers.

”The Arcam AVR390 is an excellent AV receiver, with a surround sound performance that is superior to any other model in its price range.” ‘AVForums’ – ‘Best Buy’

Dolby Atmos and DTS:X with decoding up to 7.2.4 for totally immersive sound
Dolby Atmos and DTS:X are now well established as providing truly immersive sound through ceiling or up-firing speakers. The Arcam AVR390 offers both systems, giving a 5.2.2 system with twin ceiling or up-firing speakers. This, however, is just the start. With processing for 7.2.4 channels, you can add a 4-channel power amp (or two stereo power amps) and not only double the ceiling speaker count but also add additional effect speakers – giving total sound immersion.

Certified for IMAX Enhanced
IMAX has collaborated with DTS and award-winning Hollywood sound mixers to deliver stunning levels of sound quality. Only the highest quality home cinema equipment meets the standard. IMAX enhanced content is due on HDR streaming and UHD Blu-ray and promises to offer the next step-up in sound from the already impressive DTS:X.

The Arcam sound difference
Using top quality components, the Arcam AVR390 sounds sublime with both music and movies alike. Although the 60 watts per (7) channels may seem modest, Arcam delivers this power faithfully and reliably. Suitable for use in all but the largest rooms, the Arcam delivers a sound that’s both hard-hitting with action movies but still smooth and refined with music when needed.

Wide-ranging connectivity
Featuring seven HDMI inputs and three outputs, the AVR390 can handle the most complex AV systems. Six HDMIs are HDMI 2.0a and HDCP2.2 compatible (for UHD 4K sources) with the seventh being MHL compatible (for connecting up a smartphone). Other inputs include a total of six digital and seven analogue (with a front-mounted 3.5mm AUX) inputs, making this Arcam AVR hugely adaptive to all types of sources.

HDMI Zone 2 output
Triple HDMI outputs make the AVR390 even more versatile. Use two of the outputs within the same room for connecting a TV and projector simultaneously. The third HDMI is independent, making it ideal for sound and vision in a second room (HDMI2.0a/HDCP2,2 compatible).

Dirac Live for Arcam gives you the very best sound in your room
For the very best sound in your room, Arcam has included powerful room correcting technology from Dirac Research. This uses a microphone and dedicated software to take multiple readings around your room and feed the information back to the amplifier for a completely bespoke response (professional set-up recommended).

Network control
Connect to your network via Ethernet (wi-fi not included) and you get access to a wide range of networking features. These include UPnP (Universal Plug n’ Play) for streaming from other network devices, Spotify Connect (requires Spotify Premium account) and Internet radio.

Internet, DAB and FM – all the radio you need
Internet radio opens up access to a choice of hundreds of radio stations from around the world. Backing this up, the built-in DAB and FM tuners give wide-ranging access to all your favourite stations, including popular digital only stations, such as BBC 6 Music and 4 Extra.

MusicLife iOS control app
If you have an Apple iPod Touch, iPhone or iPad, then you can take full control of streaming music to your Arcam device with the MusicLife control app. It lets you stream music directly from your device as well as servers or computers connected via UPnP (Universal Plug n’ Play). The latest version brings Internet Radio, Podcasts plus streaming from TIDAL and Qobuz. Advanced features, such as library searching, sorting, shuffle and repeat playback are also catered for.

Take a step up to reference level home cinema, with the ability to go further still, by taking a look at the Arcam AVR390. Cinema at home doesn’t get a whole lot better than this.

Yamaha boasts over 60 years of history as an audio brand. And the technology of R-N803D comes directly from Yamahaʼs legendary Hi-Fi design concept ToP-ART (Total Purity Audio Reproduction Technology), which faithfully maintains the integrity of the audio by combining a meticulously symmetrical left / right circuit layout and signal directness (straightest, shortest signal paths) with a low-vibration chassis of high rigidity, equipped with the special resin frame "Art Base” that absorbs and blocks unnecessary vibration. It maintains sonic purity and accurate stereo image of the music to create unshakeable drivability.
