It has a built-in Bluetooth module that allows you to play music through the audio streaming profile directly from your phone, laptop, microSD memory card, and flash drive. However, thanks to the AUX input, you can also connect it using a dedicated cable to your MP3 player, computer without Bluetooth function, or CD player. Additionally, there is also FM radio. With the function of saving your favorite stations, you only need to search for their frequencies once and save them in the device memory. High-quality sound is another characteristic of the new PRIME3 brand speaker. This is thanks to its 3200 W P.M.P.O. and a total musical power of 100 W. The use of a bass reflex enclosure has allowed the APS31 to achieve greater efficiency in the low frequency range and reduce non-linear distortion. A speaker with this kind of performance has to be loud, strong, and clear! The APS31 also features a karaoke function with a 6.5mm microphone socket, used in all professional sound systems, and multi-colour LED backlighting.
