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 110°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
ne
software which reduces
audio output level until the overcurrent condition is no longer present.

3.1 Installing Software
Ashly Protea
ne
software is included on a CD with each unit. Software updates may become available on the Ashly web
site. Autorun will launch the application <ProteaSystemSoftwareNE> to install the software.
Once the software has been installed on the computer and Ethernet connections with the amplifier have been made, launch
the software. All available Ashly network enabled devices will be automatically detected and displayed in the Ashly Network
device tree on the left side of the main software startup window.
Device icons can be dragged onto the project canvas from the device 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-
rently off-line. In the device tree, all currently connected and active devices are highlighted in green. Ashly devices which have
