AlphaTheta CDJ-1500X
Compact design fits in smaller DJ booths
Designed with compact DJ booths in mind, the CDJ-1500X is ideal for bars, small clubs, and home setups. While it includes many key features of the flagship CDJ-3000X, the new multi player has a significantly smaller footprint. This makes it easy to fit the multi player into tighter spaces and combine it with turntables and other gear to create a custom setup.
10.1-inch touchscreen and enhanced track visualization
The CDJ-1500X includes the 10.1-inch capacitive touchscreen from the flagship CDJ-3000X, enabling smooth track selection and intuitive performances.
The browse screen displays up to 15 tracks at once so you can view more music in a single list and quickly find your next track. And waveform previews help you understand the music’s structure at a glance, so, you can easily choose tracks that match the flow of your set.
The main waveform display now includes visual indicators for vocal positions, BPM change points, and phrase structures. This helps you easily understand each song’s progression and feel more confident when making decisions about mixing during your performances.
Using Playlist Edit, you can rearrange tracks within playlists directly on the CDJ – there’s no need to switch back to your laptop/mobile device, or re-export tracks to your USB drive.
With a choice of dark and light display modes, the information on the screen stays highly visible no matter where you’re playing – from low-lit DJ booths in clubs to bright rooms or even daytime outdoor events.
Cloud connectivity and NFC login
Access your cloud-based rekordbox library and millions of tracks from streaming services, directly from the CDJ-1500X. With built-in Wi-Fi, you can play your tracks via rekordbox CloudDirectPlay, as well as songs from platforms such as Apple Music, Beatport Streaming, and Tidal using the StreamingDirectPlay function.
You can instantly access your personal settings and playlists via NFC touch login by tapping your mobile device – with rekordbox for iOS/Android installed – on the CDJ. This, together with cloud connectivity, means you can arrive at a gig with just your smartphone and start performing immediately from your own music library.
New CoBeat service enhances crowd interaction and unity on the dancefloor
Want to interact with your crowd more and bring the dancefloor together? The CDJ-1500X is the first AlphaTheta multi player that’s compatible with the new CoBeat service, which helps your audience feel more involved in your performance.
By scanning a QR code (created by you or the venue in advance), CoBeat provides an opportunity for the audience
to browse a catalog of tracks you’ve already chosen. They can vote for you to play these tracks or send you a message to request other songs. All this information is gathered on the CDJ-1500X, where requests are displayed on the browse screen, ready for you to drop into your set and create a shared experience with the audience. People can also add emojis to each other’s requests to share the energy of the dancefloor in real time. These reactions appear as pop-ups on your smartphone screen, helping you to sense the crowd’s response while performing.
You can turn CoBeat on whenever you want to receive requests and turn it off if you prefer to just focus on your mix.
* Please note: The launch of CoBeat and the release of the rekordbox for Mac/Windows update introducing CoBeat support are scheduled for July 9, 2026.
Customizable design that blends into any space
With its minimalistic user interface and matte black finish, the CDJ-1500X blends seamlessly into any setup or space. In the front panel, an illuminated bay with 2 USB ports (1 x Type-C, 1 x Type-A), makes it easy to connect USB drives and keeps them neatly stowed away so they can’t be accidentally knocked out of place while you’re performing or if the booth is crowded. You can choose from 12 colors for the LED lighting to match the mood of your gig. And, thanks to the screw holes on the sides of the multi player, you can add optional panels to customize the look of your CDJs with different colors and materials.

AlphaTheta Euphonia
The AlphaTheta Euphonia Professional 4-channel Rotary Mixer produces a euphoric sound with the clarity of digital and the richness of analogue that’s never been heard from a DJ mixer before.
To deliver a clearer sound quality that accurately reproduces the expression of the music, the euphonia uses high-quality 32-bit A/D and D/A converters as well as 96kHz/64bit floating point mixing processing operations in the DSP, utilizing the digital signal processing technology AlphaTheta has developed over many years.
KEY FEATURES
Specially developed rotary fader makes you feel at one with the music
When you touch the faders on the euphonia, you won’t want to let go. To enhance its intuitive mixing experience, the unit is loaded with rotary faders that feature a brand-new carefully developed design to give you the feeling that you and the mixer are one. After extensive testing, the perfect knob sizes were chosen, with an elastomer applied to the outer circumference of each to ensure a comfortable and reliable grip as well as a high level of vibration absorption. The uniquely developed mechanism for the faders also benefits from optimum weighting. You’ll notice a difference in the feel of the knobs when you turn them at different speeds, as a higher load is applied when you turn a knob slowly for delicate fine-tuning and a lower load level is applied when you turn a knob quickly to instantly reach your intended volume level. And the fader volume curves have been optimized through feedback from numerous DJs, enabling smooth and natural mixing without equalizing, so you can concentrate on volume control. This innovative fader allows for musical expression that will move your audience and enhance your performance.
Energy Visualizer for understanding overall sound at first glance
Get an instant visual grasp of the status of your mix and the balance of track volume levels by glancing at the euphonia’s Energy Visualizer. Conventional VU meters only have 1 needle meter, making it difficult for DJs to grasp multiple channel levels at the same time. The euphonia’s uniquely developed Mix Level Meter features a needle meter for each channel so you can visually check the levels for all channels and mix smoothly while keeping the groove going. You can even keep an eye on the balance of the Master output by looking at the Spectrum Analyzer, which helps you keep your mixes sounding consistent and smooth, even in a long set, as you “watch” the euphonia’s output and adjust it to create your perfect sound.
Next-generation 3Band Master Isolator that transforms sensibility into sound at your will
Enjoy a more sensory level of control over your music with the 3Band Master Isolator which was specially built for the euphonia.
•Highest-quality isolator
The size of the isolator knobs is perfect for rapid turns from center to maximum or minimum, and the torque load is perfectly balanced for both quick operation and fine sound quality adjustment, with a luxurious feel that’s not too light. The cut-off frequency and slope are set to control and highlight the kick, melody, and rhythm bands in a natural yet sharp manner.
•Brand-new Boost Send for one-handed effects application
Add one of the built-in Send Effects, or an effect from an external unit, to the sound of any of the Master Isolator frequency bands. Press the Boost Send button for the low, mid, or high band and, as you turn the isolator knob, the effect will be applied to that band. This enables you to apply effects with a single hand in a way that previously needed two, leaving the other hand free for mixing another track.
•Boost Level to help you express your style
Pick the Boost Level setting that suits your playing style, and the volume level of each frequency band will be increased by the relevant amount. Choose +12dB for dynamic performances, +6dB for sound quality adjustments, and 0dB for reverb effects without any volume boost.
Built-in Send FX to bring depth and breadth to your sound
The AlphaTheta Euphonia Rotary Mixer features 5 built-in spatial effects and a high-pass filter, so you can easily add depth and breadth to your music. These are: Delay, Tape Echo, Echo Verb, Reverb, Shimmer, and HPF (high-pass filter). There’s also a Send/Return section which gives you the option to connect external effects units. A dedicated knob on each channel enables you to adjust the send level going to the selected effect, so you can apply just the right amount. And the Time knob, which allows you to adjust the effect delay and reverb time, has a proprietary mechanism developed specifically for this unit that automatically switches between a clicking sensation and no-clicking sensation depending on the effect you’ve selected. When using Delay, Tape Echo, and Echo Verb, the knob clicks according to the BPM, so you can quickly apply effects. When you use Reverb and Shimmer, there’s no clicking, so you can turn the knob freely to perform smooth sweeps or make tiny adjustments to find the perfect setting.
Design that embodies a new era of rotary mixer
The AlphaTheta Euphonia Rotary Mixer was designed to signal a new era of rotary mixers, with a “two-tone, two-layer” look symbolizing tradition and innovation. The channel strip section, which comprises traditional mixer elements, is distinguished from the innovative display section by matte and gloss textures, resulting in a crisp design that combines analog and digital elements. The copper color of the primary knobs conveys the warmness of analog sound, and the wood side panels are painted black to blend in with the overall aesthetic.
