3D Mobile Sound Processor with stereo audio amplifier

Model Number

3S-MS210M

Features

The 3S-MS210M is a 3D enhancement device with stereo power amplifiers for mobile applications.
This device has two built-in speaker amplifiers and a 3D sound processor using 3S Around Sound technique. It can be applied to any sound source such the established bell contents (16-, 40-, 64-poly), stereo midi, MP3 and any other audio content. The 3D sound processor supports two kinds of mode: narrow space speakers (NS mode) and wide space speakers (WS mode). For generating 3D sound, 3S-MS210M has no additional processing hardware device or software algorithm. Furthermore, 3S-MS210M can be placed between an audio source generator and speakers with just a minor change of application board and can be adopted to any portable devices currently on the market.

3S-MS210M's dual bridge-connected audio power amplifiers will drive over 500mW to an 8W load with less than 1.0% THD+N under 4.2V battery voltage. In addition, the headphone mode control allows the amplifiers to operate in single-ended mode, which can be used to drive stereo headphones.

3S-MS210M is specifically designed to provide high quality output with high power even with such a small package of 4x4mm2 MLF(QFN) while requiring minimal external components. It also includes a mode control switch for surround function and a shutdown mode to maximize power saving.

3S-MS210M is suitable for cellular phones, PDA, portable PCs, portable games and any mobile devices that need stereo audio and 3D surround effect.
