VI. TECHNICAL ASSISTANCE & SERVICE
Only a qualified technician should service your QSC product. There are no user serviceable components inside the unit and the
risk of electric shock exists. Also, some components in your unit may require specific QSC replacements.
Technical Assistance
If you suspect that your SPA-3 is defective, check your system configuration and SPA-3 settings to determine the origin of the
problem. Incorrect audio interfacing, poor cabling, or other system-level defects are the most frequent causes of problems in audio
systems. For technical assistance beyond the scope of this manual, contact QSC Technical Services. We also offer comprehensive
service manuals for many QSC models; contact us for details.
Factory Service
If your SPA-3 needs factory service, contact QSC Technical Services for return instructions. We will issue you a Return
Authorization (RA) number for each unit. QSC cannot be responsible for products that are returned without an RA number.
Product Return Guidelines
1. Pack the product well for protection during shipment. Upon request, QSC will provide a factory shipping carton and
packaging free of charge.
2. Include a copy of the sales receipt, your name, return address, and phone number with your return correspondence.
Please include a reasonably detailed description of the defect.
3. Call QSC Technical Services for a Return Authorization number.
4. Mark the Return Authorization number on the outside of the packaging.
5. Ship the product prepaid to QSC Technical Services at the address listed below. We recommend United Parcel Service
