• Do not expose batteries or battery pack to excessive heat such an sunshine, fire or the
like.
Caution
Intrusion of liquids
• No objects or liquids should intrude or leak into the equipment.
• To reduce the risk of fire or electric shock, do not expose this apparatus to rain or
moisture an objects filled with liquids, such as vases, should not be placed on this
apparatus.
Protecting the Speakers / Operating Safety
To prevent speaker damage, only connect the speaker cables when no signal is present on
the outputs.
Unwanted interference
RF interference on the power cord or on the line signal cables may lead to unwanted sound
interference.
In the case your are using the optional AES/EBU input, it is possible that a complete drop out
of the audio signal is possible caused by strong electromagnetic interference . This may not
be announced, like anaolg signals, by audible disturbances.
Pauses in use
The power cord should be disconnected from the power source during longer pauses in use.
Cleaning
The equipment should only be cleaned with a damp cloth when it is not plugged in.
Transportation
When transporting the device, make sure that it is protected from vibrations.
3. Product Description
3.1 TOPAS Power Amplifier
The TOPAS is a network-capable, dual-channel DSP amplifier for fixed installations. The DSP-
Amplifier was specially designed for optimal operation with Kling & Freitag loudspeakers. It is
also possible for use with other speaker systems.
Via Ethernet, the TOPAS can be highly variably switched on and off, controlled and
monitored. The four General Pupose Inputs (GPIs) allow you to adjust volume (digital VCA),
switch on/off the amplifier. mute the channels and switch the inputs of the audio signal.
You can assign events to the outputs such as amplifier status, mute status of the channels or
PRIO audio activity via the web interface. Two open collector outputs and a potential free
relay contact are available.
Further features include the integrated web server for concise configuration, easy location of
all devices in the network using AutoIP/mDNS, and the configurable access control with user/
password. The TOPAS can be operated remotely, no matter which operating system is used.
Because of the redundant firmware, updates are save and easy.
The standby power consumption is limited to 4.5 watts. The amplifier is ready to operate
within a few seconds after power on. The activation can be set via a signal over GPI, ethernet
or by pressing the front button.
The TOPAS allows you to monitor the internal protection circuits (Clipping, DC, short circuit,
temperature, voltage) via the web interface or soon, over a remote application. Permanent
monitoring of the processor via watchdog and load monitoring of the connected speakers in
the future is guaranteed. All events can be monitored via web interface or GPIO.
The functionality, performance capability, and expandability of the TOPAS ensure you a high
planning and investment reliability.
