(1977-1979) FM stereo receiver, 2x30W, ultrasonic remote control
Type numbers: 2901, 2902
The Beomaster 2400 was in simple terms a Beomaster 1900 with ultrasonic remote control. The empty area of printed circuit for this already existed in the 1900 so all that was required was to populate all the empty spaces with the necessary components and to provide a remote control unit. This unit, known as the Beomaster Control Module, was similar in both principle and construction to the Beovision Control Module that was provided with the Beovision 4402 etc, though it offered only 8 functions instead of 16. The Beomaster 2400 also offered a restyled primary operating panel which looked, if anything, even more modern than that of the Beomaster 1900. Text copyright © Beocentral.

As well as remote control, later Beomaster 2400s introduced an important new feature to the B&O range, the ability for units in an audio system to interact. In the case of the Beomaster 2400 this meant that the record player could be started, stopped and paused using the “PH” control, either on the Beomaster itself or on the Beomaster Control Module remote control unit. For this to work a specially prepared Beogram was required, initially the Beogram 4004 and latterly the Beogram 2400 and 2402 as well. The extra connections were made by adding two pins to the 5-pin PH socket. The geometry and functions of the other pins remained unaltered however, so that a conventional Beogram model could also be used without the need for adaptors. This system preceded the digital “Datalink” system that would appear a few years later but was not compatible with it. Text copyright © Beocentral. Unauthorised reproduction prohibited.
The Beomaster 2400 was replaced in 1979 by the slightly updated and improved Beomaster 2400-2. Text copyright © Beocentral. Unauthorised reproduction prohibited.
