  • Kombination eines Hi-Fi-Steuergerätes mit einem Kassettenrecorder. Automatischer Kassetten-Auswurf am Bandende, sowie die wahlweise Möglichkeit, mit dem Kassettenauswurf den Netzschalter betätigen zu lassen. Damit schaltet sich das Gerät nach Bandauswurf ab. Ein Mikrofoneingang mit eigenem Pegelregler ist so geschaltet, daß er zu allen Programmarten wirksam ist. Eignung als Hintergrund-Musikgerät für Lokale oder Geschäftsräume, bei denen fallweise Durchsagen notwendig sind.
