The ELAC Debut Connex speakers are active speakers. The Adsum version is the result of a collaboration between ELAC and ADSUM, a trendy American clothing brand. The master speaker serves as the central unit, while the slave speaker is connected to it via a conventional speaker cable. Depending on your setup preference, you can choose whether the master speaker should be positioned on the right or left. With the HDMI connection, the speakers are suitable for connecting to a TV. Additional external sources can be connected via USB, digital optical, and stereo RCA. For the stereo RCA, you can choose to connect either a conventional stereo source or a turntable (Phono MM switchable). The Sub OUT provides the option to enhance the system with an ELAC subwoofer.
