ELAC SUB 2090 - Advantages of BASH Technology; The SUB CONTROL APP

Advantages of BASH® Technology
The BASH® technology implemented in the amplier module of the ELAC subwoofer
oers the customary impressive power reserves but with much lower levels of distor-
tion. This is achieved by using an audiophile class A/B power amplier whose supply
voltage is regulated by a classD amplier circuit to prevent any unnecessary power
losses and to achieve the eciency of a class D amplier. Therefore, BASH® technology
combines the advantages of both technologies.
Since the audio signal is amplied in the analogue domain, the high-frequency
interference typical of digital ampliers is eliminated. This design results in a low-noise
amplier with lower electromagnetic interference emissions.
The absence of crossover distortion, which is a problem in traditional classD designs
where the switching speed of the transistors is limited, yields a further improvement in
total harmonic distortion.
THE „SUB CONTROL“ APP
Your ELAC subwoofer incorporates an advanced, digital control system. Analog rotary
potentio meters and switches have been replaced by a digital signal processor (DSP),
which allows you to adjust your subwoofer conveniently and accurately. All parame-
ters, such as volume, cuto frequency, phase etc., as well as the automatic calibration
function, can be conveniently adjusted with the help of the free APP.
The digital control system also eliminates the possibility of unwanted changes to
controls and settings.
Note: The APP used to control the subwoofer does not require any complicated
connections to your home broadband (WLAN) network. The control system operates
using Bluetooth® Low Energy (BLE).
Please go to the relevant source and download the “SUB CONTROL” APP required to
control the subwoofer. For Apple® iPhone® and iPod® users, this is the Apple® App Store®.
Android® users should visit the Google® Play Store®.
Enter “ELAC” or “SUB CONTROL” as a search term and look for the icon shown below.
Please note that your mobile device must support Bluetooth® Standard 4.0. This
is the case for the majority of devices sold as of mid-2013. If necessary, check the
accompanying documentation for your mobile device or contact the manufacturer’s
support hotline.
Note: In case your mobile device needs a 4 digit code during the subwoofer-pairing-
procedure, please enter four times zero („0000“).
