Register a repair
Choose the appropriate request type depending on the repair — paid or warranty.
Paid repair
To submit a paid repair request, fill out the registration form in our system. After receiving your request, print it and include it with the package, or label the package with the RMA number.
By default, we do not order a courier — you can deliver the equipment personally or ship it yourself. However, if you need us to arrange a courier pickup, indicate this in your request. Shipping costs will be added to the repair.
Pioneer DJ warranty repair
Warranty repairs for Pioneer DJ and AlphaTheta devices are processed through the manufacturer's official system. To submit a repair, follow these steps:
Fill out the repair registration form at repair.pioneerdj.com. The form is in English.
If you prefer not to fill out the English form, use the Polish paid repair form and indicate that it concerns a warranty repair. We will complete the warranty form on your behalf and send you the shipping label.
Important: In the form, for the question "Brought in to ASC", select "No" to receive a shipping label.
After completing the form, ship the device — bring it to the nearest UPS Access Point or schedule a UPS courier pickup via the UPS website.
After registering your request and shipping the device, we will contact you regarding further repair details.
Shipping your equipment — how to prepare the package
You can deliver your equipment in person or ship it by courier from anywhere in Poland. A well-protected device means a faster repair and no additional damage in transit.
- 1
Register the repair before shipping
Fill out the request form, print it and include it with the package, or label the package with the request (RMA) number.
- 2
Pack the device securely
Ideally use the original carton. If you don't have it, choose a sturdy box larger than the device and leave about 5 cm of cushioning (bubble wrap, foam) on each side. Protect moving parts such as jog wheels and faders from pressure.
- 3
Include only the necessary accessories
Include the power supply or cable only if the fault may be related to it. Do not ship bags, covers or other unnecessary accessories — this reduces the risk of losing them.
- 4
Label the package and describe the fault
Label the package with the request (RMA) number and include a short description of the fault and your contact details inside.
- 5
Return after the repair
After the repair we ship the working device back by courier, or you can pick it up in person in Warsaw. Shipping costs are added to the repair.
If you would like us to arrange a courier pickup, indicate this in your request — shipping costs will be added to the repair.
