Trigger input
So that the amplifier is not always switched on, it is possible to use the trigger input to control on/off. A DIP switch is used to
set whether the trigger input should be used.
0-10V input
The volume can be adjusted with a 0-10V signal. If variable volume is not desired, the RA410v2 will operate at 100% in standard
mode. The RA410v2 supplies 10V at one connection in order to use a simple potentiometer to control the volume.
0-10V signals from e.g. SmartHome control systems can also be used, or the output of a 0-10V KNX dimming actuator.
Balance and Volume control via built-in potentiometer
Two built-in small potentiometers allow you to adjust the level of the 2 amplifier channels. This enables a balance setting - and
also the limitation of the maximum volume.
2 DIP switches for configuration
You can configure the amplifier with the 2 DIP switches.
Amplifier
The digital stereo amplifier delivers 2x40 watt at 8 ohms. It can drive a minimum of 4 ohm loads. This also allows you to oper-
ate a several 8 ohm loudspeakers in parallel on one output.
Thanks to the digital power amplifier, the amplifier develops little heat and is therefore suitable for DIN rail mounting. Never-
theless, it is advisable to ventilate the control cabinet sufficiently.
