18 ABSTRACT: "Apparatus for driving one or more transducer units." An apparatus for driving n transducer units (5.1, 5.2, ..., 5.n) (n>1), each comprising one or more electro-acoustic transducers, comprises m signal inputs (1.1, 1.2, ..., 1.m) (m ?, 1) for connecting m signal sources (2.l, 2.2, ..., 2.m) to the apparatus, each sig- nal input being connected to an associated amplifier unit (3.1, 3.2, ..., 3.m), and n signal outputs to which said transducer units may be connected, a signal input being connectable to one or more of the signal outputs via the associated amplifier unit. The apparatus further comprises k auxiliary camplifier units (6.1, 6.2, 6.3, ... 6.k) (k?1), one or more of said auxiliary amplifier units being con- nectable in parallel with an arbitrary amplifier unit. In this way the total power installed in the apparatus may be reduced substantially. (Fig. 1).
