The PRO DJ LINK stem engine ●

CHURRDJ_

CHURRDJ is a plug-and-play stem player for Pioneer / AlphaTheta DJ rigs. It splits your tracks into vocals and instrumental and plays them on two spare mixer channels, locked in time to your CDJ — so you can drop an acapella or pull the vocal live without ever touching your decks. It arrives preconfigured and ready to use.

Secure checkout via Stripe. Card & shipping details collected at checkout. Ships worldwide — shipping calculated by destination. International orders: any import duties, VAT, customs fees, taxes, or tariffs are the buyer's responsibility — not included in the price or collected by CHURRDJ, and may be charged by your local customs authority on delivery. Supported on the Pioneer / AlphaTheta USB-DJM family.

Do I have to set anything up? +
Almost nothing — it arrives preconfigured and ready to go. Run one ethernet cable into your link, patch the audio out to two spare mixer channels, and power it on. It boots straight into the live engine.
What gear does it work with? +
It's built and tested for PRO DJ LINK rigs on the Pioneer / AlphaTheta USB-DJM family — validated end-to-end against a CDJ-3000X and DJM-A9. Other USB-DJM mixers in the family are supported; we confirm compatibility with the rig you list when you order.
Does it take my decks offline? +
Never. CHURRDJ rides alongside PRO DJ LINK as a sidecar — it reads the link to stay locked to your CDJ, but it never takes the network down. Beat sync, stacked waveforms, and your normal workflow stay exactly as they are. The stems just show up on two spare channels.
What does $649 cover? +
The complete unit: enclosure, the preconfigured compute inside, a backup system card, the full cable kit, a spec-matched power supply, the quick-start card, and lifetime signed firmware updates. Built to order in San Jose. Shipping is calculated at checkout; import duties, VAT, and taxes on international orders are the buyer's responsibility.
When does it ship? +
Every unit is built to order. You pay in full at checkout to secure your unit, and pre-orders are estimated to ship by late July 2026. Each unit is assembled, imaged, and bench-tested before it leaves the bench in San Jose.
Taxes, duties & refunds? +
US sales tax is calculated at checkout where applicable. For international orders, any import duties, VAT, customs fees, taxes, or tariffs are the buyer's responsibility — they're not included in the price or collected by CHURRDJ, and your local customs authority may charge them on delivery. Every unit carries a 30-day rig guarantee: if it won't run on your supported setup, you get a full refund.
