A Receiver Designed to Integrate Bluetooth into a Professional Audio Chain
The Alctron BX-4 positions itself as a compact solution to bring the convenience of Bluetooth to a traditional audio system. It is intended for setups where quick streaming from a smartphone, tablet, or any other compatible device is desired, while maintaining a "stage" connection via a 3-pin XLR output. The goal: to simplify the playback of background music, tops, lesson materials, or playbacks without adding extra cables.
Intended Uses and Users
The BX-4 is particularly suitable for mobile DJs, stage managers, hosts, music teachers, gyms, bars, small venues, and event providers who want a quick-to-set-up wireless connection. It is also useful in rehearsals to send an audio reference or backing track to a PA system. Thanks to the STEREO-LINK function, it becomes relevant when stereo playback is needed with two receivers, while keeping the setup lightweight.
