OneConcept BSX-28A PA Speakers USB microSD AUX MIC 60W RMS Black

Versatile set of active and passive speakers with 2 x 20cm (8") woofers, 60 watts RMS power and extensive karaoke section.

Direct MP3 music playback from USB flash drives and microSD cards as well as wired audio devices.

Light bass reflex enclosure with carrying handle and protective metal edges.

The OneConcept BSX-28A speaker set consists of an active and a passive component, which together provide rich sound, versatile connectivity and a portable design with a focus on Karaoke applications.

With 60 watts of RMS power, linear tweeters and two powerful 20cm (8") woofers, the OneConcept BSX-28A master-slave speaker system produces a dynamic sound with clear highs and a punchy bass. The bass reflex design provides additional emphasis.

Via the OneConcept BSX-28A speaker set's front USB and SD ports, MP3 files can be played directly from the appropriate media. Via the RCA line input jack and auxiliary input boxes, the speakers may be connected to wired audio devices such as smartphones, CD players or laptops.

The karaoke section, which features two microphone jack inputs with dedicated volume controls and echo effect, makes singing and voice-based events easy.

The OneConcept BSX-28A speaker system is easy to transport thanks to its relatively lightweight yet rugged bass reflex enclosure as well as its convenient carrying handles on top of the boxes. The speakers can fit easily even in smaller car boots. An edge protection made of metal and a speaker cover protect the boxes from possible damage during transport.
