Protective Circuits
Your new Warwick Gnome amplifier comes with multiple protective circuits to prevent malfunctions under unsuitable operating conditions.

Over-Current / Short-Circuit Protection
The amplifier features an over-current / short-circuit protected output. A current drop occurs when the amplifier exceeds the specified peak current output. This goes along with the drop in the voltage of the amplifier. If the current output of the amplifier exceeds its specified peak current output for a longer period of time e.g. in case of a short circuit of the output, the amplifier will be disabled (muted) for 1000 ms and automatically restart.

DC Output Protection
A built-in DC protection circuit will attenuate any DC signals on the power amplifier input, produced by a signal containing a DC signal. In case of a permanent DC on the output of the amplifier, the amplifier will latch and power must be removed for the product to restart.

Excessive Temperature
This circuit protects the power stage from malfunction by switching the device off if the temperature-regulated fan cooling proves to be insufficient and temperature of the unit is too high.
