5. Configuration and Operation
5.1 Modes of Operation
The device has three modes of operation:
• the standby mode,
• the operating mode,
• the error mode.
5.1.1 Standby Mode
After you have connected the TOPAS to the power supply, the device switches into standby
mode as a factory setting.
The main power supply and the audio signal processing are deactivated. The network and
the control elements are still available when the device is in the standby mode. The standby
power consumption is less than 5W.
If you want the amplifier to start up in the operating mode after being switched on, you can
change this in the web interface (see page 40). This can be useful when the amplifier once
again comes back to life after a power failure and the device should automatically switch to
operating mode.
5.1.2 Operating Mode
Different events can trigger the amplifier to switch to the operating mode 'ON' (ready for
operation). The operating status is visually indicated on both channels by illuminating the top
status indicators (LEDs). (see page 11 - Pos.B / C)
The amplifier is ready to operate within a few seconds after power on.
5.1.3 Error Mode
The amplifier switches to the error mode when there are serious errors.
The main power supply is switched off in the error mode.
Caution
If you are able to determine that external error influences (such as short circuits, etc.) and
you can correct it, you can reset the amplifier on the power button or on the web interface.
Please contact your dealer.
To determine the actual source for the shut-down due to an error, Kling & Freitag has to
examine the device. To have this done, you must send it in. (see manufacturer address on
page 6) Ask your dealer.
5.2 Configuring the Modes of Operation
With the following actions, you can switch between the standby and the operating modes:
• push the front button,
• via web interface,
• impulse via GPI,
• command via XML/Remote.
When the TOPAS is connected to a power supply, it automatically switches to the standby
mode. If you want the amplifier to switch to the operating mode after being connected to
the power supply, you can change this in the web interface (see page 40).
