3" Master/Slave High Resolution Desktop Speaker System



3" Master/Slave High Resolution Desktop Speaker System

Each SC203 setup is configured as a 2-way master-slave system, and features four power amplifiers. Each woofer and tweeter gets its own dedicated 30W PWM amplifier with separate filter section for precise control. 
And for optimal connectivity, the SC203 houses three inputs – analog RCA, digital optical and USB – which will allow you to conveniently connect a wide range of sources. Furthermore, a volume controlled subwoofer output lets you connect an additional subwoofer (TS107 und TS108) to the master speaker and create a powerful 2.1 system. A DIP switch located at the speaker's back panel allows you to select the SC203's to work as "satellites" from 80Hz and upwards, or as a full range units.

The µA.M.T. Tweeter

The simple goal of bringing the sound quality, low distortion and high resolution of our now famous A.M.T. tweeter to a much smaller format speaker took us on a many-month journey to find the perfect solution for the SC203. In the end, a new tweeter was born: the new µA.M.T.. 
This high resolution µA.M.T. delivers an astonishing high frequency resolution combined with extraordinary precision and clarity.


With every EVE Audio speaker, you also get high resolution DSP electronics. 
One push knob operation and you will have access to accurate volume control, balance and several different filter settings (High shelf, Low shelf, LED brightness, Input selector and Speaker-Position such as Flat, Desk and Console) to tailor your set up comfortably and with ease to the way you work. An LED indicates clearly the status of each setting you have chosen. 
And if you always avoid digital processing, we've got you covered. The DSP engine is supported with a high quality 192kHz/24bit A/D converter from Cirrus Logic, which delivers a pristine signal to the DSP section. And since the PWM amplifiers are directly connected to the DSP, no additional conversion is necessary. When the optical digital input is used, the Cirrus Logic converter is removed from the audio path to avoid any additional conversion.

Passive Radiator

Passive radiator technology can be simply understood as having a passive woofer unit, along with the main active driver that does most of the work. This way, the internal air pressure generated by the active driver is used to move the passive radiator in order to reproduce lower frequencies than standard speakers with similar dimensions. 
Also, the reason you don't usually see this kind of technology in smaller pro-audio systems is mainly because of cost and engineering concerns. Passive radiators are more expensive and not so easy to precisely tune them. 
Another advantage of our passive radiator is the complete elimination of all audible noise related to air turbulences, as there are no reflex tubes involved with this design. Unwanted pipe resonances (at multiples of half the fundamental wavelength), which are unavoidable with two-sided pipe openings, are eliminated this way. 
We've also built a custom suspension for the passive radiator, which exerts a restoring force underneath its tuning frequency, thereby reducing inaudible excursions of the speaker into the subsonic range. This results in reduced intermodulation distortion in the audible spectrum. 
In short, thanks to the passive radiator technology being used (and a few more engineering secrets, of course), the SC203 works and behaves as a fully fledged full- range speaker, with precise bass reproduction and a very small footprint.
