How to use

Connect the main unit to mains power and switch it on. Select the desired input using the front panel or the IR remote: Bluetooth for wireless streaming, CD for disc playback, USB for files on a memory stick or Line In for an external device via 3.5 mm cable. Use the equalizer presets to adjust bass and treble according to the genre. Tune the FM radio and save up to 40 presets for quick access.

Usage recommendations

Place the main unit and speakers on stable, level surfaces and allow some space around the subwoofer for proper bass dispersion. For best Bluetooth performance, keep the transmitting device within typical indoor range (around 10 m) and avoid obstacles between the device and the main unit. Use the appropriate equalizer preset for the played genre to achieve balanced sound.
