3.2 Concept of a Network Enabled Amplifier
The TOPAS was developed to enable the highest possible operating safety of an entire sound
system. In the future, it offers not only speaker-specific pre-amplifier control functions such as
equalisation and limiters, but also further functions, such as:
• permanent status monitoring of the processor
• continuous load-monitoring in order to monitor the connected speakers,
The amplifier is, therefore, an intelligent device for the monitored channels.
If the amplifier is used in a multi-channel installation, the status information of the amplifiers
must be provided to a central control unit. This device can be a media control system,
a computer, or a simple display on a control console. For this networking with other
components of the given control infrastructure, several interfaces are available:
• analogue interfaces (GPIO) in 0-10V and open collector technology
• Ethernet ports
The Ethernet ports offer:
• access to the configuration via the integrated web interface
• monitoring of several amplifiers using the Kling & Freitag remote software, which will
be available at a later date
• HTTP/XML interface for controlling via XML-Post/Request media control units
To enable an affordable and powerful networking with standard components, the device
has a 10/100Mb Ethernet adapter. An integrated switch provides two rear mounted Ethernet
ports for connecting several devices. Additionally, there is a front port for service purposes.
When using a configurable Ethernet switch (RSTP Switch) (Rapid Spanning Tree Protocol), you
can also setup redundant ring networks.
Locating the device in the network is also possible without knowing an IP address using the
standardised ZeroConf/AutoIP protocols.
