At the High-End Show in Munich, Technics unveiled the latest addition to its OTTAVA line of all-in-one music systems. The new S SC-C50 is a 3.1-channel design that incorporates three midrange drivers, three tweeters, and a subwoofer; the internal amp delivers 20 watts to each speaker and 40 watts to the sub. Inputs include USB, optical digital, and a 3.5mm aux in. The networkable system features TIDAL, Spotify, Deezer, and Internet radio built in, and it supports Chromecast and Bluetooth. More details are provided in the press release below.


From Technics
Technics unveiled the new OTTAVA S SC-C50 Premium Wireless Speaker System at the High-End Audio Show in Munich. In spite of its compact size, the OTTAVA S SC-C50 offers acoustic technologies that deliver clear sound across a remarkably wide soundstage. A room calibration technology also allows free speaker placement, and highly diverse network reproduction is supported for an advanced wireless music experience.

Amazingly clear, deep sound for a room-filling sound stage
• 4 JENO Engines and LAPC (Load Adaptive Phase Calibration)
Technics' original Four JENO Engines produce optimal performance, with superior sound imaging through subwoofer, midrange, and tweeter alignment. This achieves excellent tuning and optimizes 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 optimized for the low-frequency and high-frequency speaker load characteristics are pre-set in the LAPC computation circuit of the unit to realize ideal frequency and phase characteristics over the entire frequency range.

• A Compact Body with a Wide Sound Stage
The arc-shaped body houses 3 midranges, 3 tweeters and 1 subwoofer, while left- and right-angled speakers and a center speaker create rich stereo imaging and crisp vocals. A "directivity-control horn" eliminates mutual speaker interference to achieve wide directivity, and a coaxial midrange and tweeter ensure 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 optimizes 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 optimize the sound from the main unit or a smartphone app with a single touch.

Broad selection of streaming 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 analog/optical input, the OTTAVA S SC-C50 supports Bluetooth, Google Chromecast, Spotify, Tidal, and Network Playback, allowing comfortable playback of a diverse range of music sources from a single unit.

• Favorite Function
Up to 9 presets can be set on the main unit, such as favorite 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.

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.
