Berlin, Germany, 2018-08-29 – On the occasion of IFA 2018 show in Berlin, Technics will showcase the new OTTAVA™ S SC-C50 Premium Wireless Speaker System, coming to stores from September.

OTTAVA™ S SC-C50 offers acoustic technologies that deliver clear sound across a remarkably wide soundstage, all in a compact size. Its room calibration technology allows for free speaker placement to enjoy your music anywhere at home.  A truly advanced wireless music experience: thanks to its complete compatibility with various streaming services, voice control capabilities and the integration of different music sources.

Clear and deep sound for a room-filling sound stage

Four JENO Engines and LAPC (Load Adaptive Phase Calibration)
Four of Technics' original JENO Engines produce optimal performance, with superior sound imaging through subwoofer, midrange, and tweeter alignment. This achieves excellent tuning and optimises sound spaces to fit individual listening environments using Space Tune™. The OTTAVA™ S SC-C50 also features the LAPC function, which is load adaptive amplifier technology developed by Technics. LAPC measures the amp's frequency amplitude phase characteristics with speakers connected to the unit, and performs digital signal processing to achieve the ideal impulse response. Parameters optimised for the low-frequency and high-frequency speaker load characteristics are pre-set in the LAPC computation circuit of the unit to realise ideal frequency and phase characteristics over the entire frequency range.

A Compact Body with a Wide Sound Stage
The unique arc-shaped body houses 3 midrange drivers, 3 tweeters and 1 subwoofer, while left- and right-angled speakers and a centre speaker create rich stereo imaging and crisp vocals.  The “directivity-control horn” approach for the midrange/tweeter array eliminates mutual speaker interference to achieve wide directivity, and the coaxial midrange and tweeter construction ensures vertical directivity with less frequency disorder from the compact body.

Truly Powerful Architecture
Three 1.6-cm tweeters deliver high-res sound up to 50 kHz. This combines with a front-firing 12-cm long-stroke subwoofer and a straight, large-diameter, long port. A total of 7 units in the rigid, glass fibre body produce powerful sound from the 3.1-channel amplifier.

Optimal sound for any listening environment

Space Tune™
To provide the OTTAVA™ S SC-C50's excellent sound in every room and listening position, Space Tune™ optimises the listening environment to the sound space. In addition to offering 3 preset modes to suit the mounting location, a microphone built into the main unit enables an Auto function to optimise the sound from the main unit or a smartphone app with a single touch.

Broad selection of services, easy-to-use controls

Google Chromecast Built-in
Google Chromecast compatibility makes it easy to enjoy a wide variety of music streaming services from a smartphone. And since the data is streamed directly to the main unit, there is no degradation in sound quality. Using a number of Google Chromecast built-in speakers, the same song can be played in several rooms, or different music can be played from room to room, for multi-room entertainment.

* The Google Home App is required.

Works with Google Assistant
If a Google Voice-activated Speaker is included in the same network, Google Assistant can be used to operate OTTAVA™ S SC-C50 music playback and other functions. When the user doesn't have a smartphone app in hand, or when hands are full, music can be easily played by voice command.

Complete Compatibility
In addition to USB playback and analogue/optical input, the OTTAVA™ S SC-C50 supports Bluetooth, Google Chromecast, Apple Airplay, Spotify, Tidal, and Network Playback, allowing comfortable playback of a diverse range of music sources from a single unit.

Stereo Pairing
Just connect and pair two SC-50 speakers via the Technics Audio Center (TAC) app – to give users a fantastic wide-screen stereo experience.

Favourite Functions
Up to 9 presets can be set on the main unit, such as favourite internet radio stations, a Spotify playlist, and USB songs. This makes it possible to listen to your favourite music without even starting up an app.

The premium wireless speaker system SC-C50 will be available in black and white from the end of September. The suggested retail price is 749,00 Euro.

An Elegant and Timeless Design

The OTTAVA™ S SC-C50 combines practical function with elegant design. The thick aluminum top panel increases the rigidity of the chassis, and the iconic OLED is surrounded by ring keys for easy operation. Rear louvers add further elegance while enhancing the function of an internal heat-reducing mechanism. And the beautiful arc form, which helps to eliminate unwanted vibration in the chassis, incorporates acoustic technology to achieve a wide sound stage. This lets you freely place the OTTAVA™ S SC-C50 to suit the listening position. And you can also choose a black or white colour to match your room decor.
