Your new subwoofer is equipped with special protection circuitry to provide maximum performance with
greatest reliability.
The protection circuitry prevents overheating and operates constantly without being audible. In some extreme
situations (e.g. sustained high output levels in warm environments), the unit may shut down momentarily.
This indicates operation of the thermal or over-current protection circuitry. If this should happen, turn the
Amplifier off with the main power switch, and let it rest for 10 min before you turn it back on. If the same issue
occurs again, please contact XTZ personnel.
WARNING: There is no protection circuit for longterm excessive volume use for some parts in the amplifier

Note: If clear audible distortion appears at high volumes, it is recommended to lower the volume.
