5.2POWER OUTPUT with 100 V speaker systems
The use of speaker systems with a 100 V matching transformer is recommended to reduce the lack in performance when the distance between amplifier and speaker systems exceeds 50 m. This method also offers an easy way of output power distribution. The total power consumption of the maximum amount of the connected speaker network has to match the amplifier’s overall output capacity of 100 W (with an impedance of 100 ohms). The connection is performed via the 100 V output (17) (see also diagram 3).

5.3POWER OUTPUT with low impedance speaker systems
After switching the output to 20 V, low impedance speaker systems (4 - 16 ohms) can be connected to the corresponding output (see also diagram 4). Because of an occurring drop in the overall performance, the distance between amplifier and speaker systems should not exceed 50 m. It is of further importance that the overall impedance of the speakers does not decline 4 ohms and that the individual power handling capacity of each speaker is not exceeded.
Free combination of the DPA 4410’s power output voltages, including mixed 100 V and low impedance (4 ohms) operation, is possible.
