PROTECTION SYSTEMS
Protection
1. D.C. Protection In the event of a DC voltage appearing at the output terminals, the
protection relay will be energised and disconnect the loudspeakers.
2. Thermal Protection If the amplifier internal temperature rises above 63ºC, the fans
will switch on to aid cooling. If the temperature rises above 90ºC then the thermal
protection circuit will disconnect the power supply from the amplifier and energise the
speaker protection relay to disconnect any overload conditions. The Thermal LED will
light to indicate that the protection circuit is in place. The amplifier should be left powered
ON to allow the fans to cool the output heatsink. The protection system will reset once
the temperature falls to a safe level. In the event that the thermal protection circuit does
become active, this indicates that there may be an underlying fault such as an output
overload condition or inadequate ventilation. The fault may need to be rectified before the
amplifier can continue to be used.
