2.3 Protection Features
PA Series amplifiers provides extensive protection including output current limiting, thermal protection,
and circuit breaker.
1. Output Current Limiting
Output Current Limiting circuitry protects the amplifier output stage for damage caused by short-
circuit loads
2. Thermal Protection
The Thermal Protection circuit will activate if the internal heatsink temperature exceeds proper
operating temperatures (85 °C or 185 °F).
When the heatsink temperature has fallen to a safe level (75°C to 80°C or 167°F to 176°F), this
protection circuit will automatically be reset. Principle causes of thermal protection are:
1) Inadequate ventilation of the equipment rack
2) Incorrect load impedance
3) Output cable short circuit
4) Blocked air vent
5) Heatsinks in need of cleaning
6) Cooling fan failure.
The cause of your amplifier’s thermal protection state should be determined and corrected as
soon as possible. Without correction, the Thermal Protection circuit will typically reactivate.
3. Fuse Protection
The high-voltage power supplies of your Sing Easy amplifier are protected by a fuse.
