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