ABSTRACT:
An audio amplifier arrangement comprises an amplifier unit containing an amplifier circuitry, and a manipulation unit, independent of said amplifier unit, having manipulation elements for controlling the operation of the amplifier unit. These two units can be detachably directly coupled together both electrically and mechanically by terminal connectors and by mechanical locking means provided on these two units for operation as a complete amplifier assembly. These two units, furthermore, are operable also in their separate state or in a "remote-control" mode of operation by electrically coupling said terminal connectors together by the use of a connector-equipped cable means applied between these two units.
