[3 Playback Modes]: Record player supports vinyl, Bluetooth reception, and RCA output. In turntable mode, it can directly play vinyl records; In Bluetooth 5.4 mode, it wirelessly streams digital music from smartphones or tablets; the RCA output interface can connect to external audio systems for an enhanced audio experience. [3-Speed Adjustment]: Vinyl player employs a belt-drive system that effectively minimizes motor vibration and noise. The turntable supports three adjustable speeds (33/45/78 RPM) to accommodate all your 7", 10", and 12" vinyl records. A 45 RPM adapter is included to hold the record in place and prevent it from slipping during playback. [Built-in 2 Speakers]: Vinyl Record Player can play records directly without external equipment. As an entry-level model, the speakers have inherent limitations in frequency response and dynamic range. To further enhance audio quality, an RCA line output is provided to connect to an external hi-fi audio system, delivering richer audio detail. [Shock Absorption Design]: A spring suspension system decouples the turntable platter from the base cabinet. This crucial design effectively absorbs vibrations from the speakers, preventing interference with the stylus and ensuring stable playback. Therefore, the slight gap between the platter and the base is a necessary and normal design feature. [Smart Protection]: The Bluetooth turntable is equipped with a detachable dust cover to effectively prevent dust buildup. When activated, the auto-stop function will automatically halt the turntable upon record playback completion. This prevents unnecessary wear and tear on both the stylus and records, extending the overall service life of the equipment.
