Gemini CDM-4000BT Dual CD/USB DJ Media Player With Bluetooth and 2-Channel Mixer

Mix CDs, USB media and Bluetooth audio without a computer using the Gemini CDM-4000BT dual CD/USB DJ media player with Bluetooth and 2-channel mixer. Designed for mobile DJs, clubs and permanent installations, this standalone system combines two independent playback decks with an integrated 2-channel mixer in a rack-mountable design. Each deck supports CD, CD-R and MP3 disc playback alongside USB storage devices up to 64GB, giving DJs flexibility when working with different music libraries. Bluetooth connectivity allows wireless audio streaming to either channel, while switchable line inputs accommodate additional external sources. Touch-sensitive jog wheels provide hands-on control for scratching, searching and pitch bending, and blue-backlit LCD displays keep playback information visible in low-light environments. With dedicated mixing controls, microphone inputs and multiple output connections, the CDM-4000BT brings essential DJ performance functions together in one self-contained unit.

Dual Playback Decks With Hands-On Performance Controls

Two independent CD/USB decks let DJs cue and mix tracks from different media sources without relying on a laptop or DJ software. Each deck features a touch-sensitive jog wheel with rubber grips and selectable search, scratch and pitch-bend functions, allowing precise navigation and real-time track manipulation. Pitch adjustment of ±10% provides additional control when matching tempos between songs, while onboard looping functions support creative transitions and extended mixes. Dedicated playback controls and blue-backlit LCD displays make it easier to manage tracks and monitor deck settings during a performance. The integrated 2-channel mixer brings both decks together, with a crossfader for transitioning between sources.

Bluetooth Streaming and Versatile Audio Connections

The CDM-4000BT supports a range of playback sources for DJs working across different music formats. Alongside CD, CD-R and MP3 disc compatibility, two USB playback ports accommodate storage devices up to 64GB, with support for FAT, FAT32 and NTFS file systems. Bluetooth streaming can be assigned to either mixer channel, allowing audio from a compatible phone or tablet to join the mix. Two stereo RCA line inputs provide connections for external audio equipment, while dual 1/4" microphone inputs accommodate vocal announcements. Balanced XLR and RCA master outputs, an RCA record output and both 1/4" and 1/8" headphone connections provide flexibility for connecting sound systems, recording equipment and monitoring headphones.

Rack-Mountable Design for Mobile and Installed DJ Systems

Built around a standard 19" rack-mountable format, the CDM-4000BT integrates dual media playback and mixing functions into a single unit for mobile DJ rigs and fixed installations. Its standalone operation eliminates the need for a computer or software controller, simplifying setups in bars, clubs and event spaces. Blue-backlit displays support visibility in dark booths, while a stereo output level meter helps DJs monitor the overall signal. Fader relay start functionality provides another option for controlling playback during transitions. Supplied with a power cable and two RCA cables, the Gemini CDM-4000BT dual CD/USB DJ media player with Bluetooth and 2-channel mixer offers a consolidated playback and mixing solution for DJs who work with physical media, USB libraries and wireless audio sources.
