Important Notice:

Pallet amplifiers are sensitive devices. If you lack sufficient experience, consider a fully assembled product instead.
Damage may occur due to:

• Excessive drive power
• Over-voltage supply
• Inadequate cooling or fan usage
• Operating without a proper load

For this reason, no warranty is provided for pallet amplifiers. However, each unit is thoroughly tested and guaranteed to be 100% operational at the time of delivery.
