POWER 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).

POWER 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.
