System Amplifier K&F TOPAS<br />
The amplifier is equipped with a thermal inrush current limiter. To prevent an excessively<br />
high inrush current when quickly switching between operating and standby modes, the<br />
device has a power-on delay (which is integrated into the firmware) of approx. 10 seconds.<br />
You can configure the power-on events in the web interface under the menu item Setup »<br />
on/standby.<br />
5.3 Operating Concept<br />
The TOPAS is a network-capable, dual-channel DSP amplifier for fixed installations. The unit<br />
has a variety of functions and settings that are too complex for a standard display. This is why<br />
we do without such a display. You can comfortably control and monitor the device with the<br />
integrated web interface via Ethernet (remote or XML), GPIO's, or with the remote software<br />
that will be available at a later date.<br />
You can find general instructions for using the web interface in the chapter Integrated<br />
Web Interface (page 17). Information for configuration is in the respective function<br />
descriptions.<br />
For the most important parameter requests (on/standby, volume control) are in addition to<br />
the web interface controls and status displays on the device.<br />
