5.4POWER OUTPUT 100 V with double output capacity
If the output power of one output is not sufficient to feed all cabinets that are incorporated within a speaker network and it is not possible to divide the speaker chain, doubling the output power can be achieved by coupling the outputs of two DPA 4410. In that case the amplifier inputs are paralleled and the outputs are connected in series (see also diagram 5).
Coupling is possible under the following restrictions: only identical amplifiers can be connected. Since doubling the output voltage comes along with the serial connection, it is necessary to switch the outputs of both amplifiers to 50 V (see also paragraph 8), resulting again in 100 V overall output voltage. In this case the speaker chain’s minimum load impedance is 50 ohms. The LEVEL controls (13) of the two DPA 4410 have to be set fully to the right.
This procedure results in the following output combinations:
4 x 100 W or 2 x 100 W + 1 x 200 W or 2 x 200 W
For information about the input connection, please refer to paragraph 4 of this manual. For the connection of the speaker network, please refer to the diagram below.
Attention During the operation the pins of the POWER OUTPUT strip may conduct dangerous voltage (> 34 V in peaks). Therefore, the connected speaker networks have to be installed in accordance to applicable security regulations (see also paragraph 9.2).
