Operating Manual - Pema Protea Equipped Media Amplifier
2.6 Amplifier Protection
Ashly Pema amplifiers have the following protection circuits:
Over Current Protection - When the output current exceeds the amplifier's safe operating limits. This occurs in the
amplifier output stage.
Thermal Protection - When the internal temperature is below 40°C the fan runs at its slowest speed. Above 40°C the
speed is increased until it reaches its maximum value. If the temperature exceeds 100°C, the input on that channel is reduced.
If the temperature exceeds 120°C, the power supply is switched off.
Mains Protection – Protection within the power supply includes: In-rush Current Limitation during power up, Mains
Over Voltage Detection, and internal Mains Fuse Protection. To protect the Mains fuse against AC overcurrent due to excessive
audio output current, there is a protection scheme indicated on the amplifier front panel and in Protea
audio output level until the overcurrent condition is no longer present.

Device icons can be dragged onto the project canvas from the menu tree, or placed as virtual devices in "Design Mode".
In other words, a device icon on the canvas is not necessarily a live product. It may be a virtual device, or a device that is cur-
