B&O Bang & Olufsen Beomaster 1400 Tuner/Amplifier, 1964-1970, made in Denmark

Manufactured: 1967 - 1970
Designer: Henning Moldenhawer
Colours: Rosewood, Teak

"A splendid example of engineering and up-to-the-minute design, this all-transistor high-fidelity mains radio was developed by B&O for the ever-increasing number of listeners who want a radio which "has everything"

Its excellent FM section has five push-buttons. One is the usual FM bandswitch button; each of the other four can be individually tuned and locked to any station in the FM band, permitting you to tune in your favourite programmes at the touch of a button.

The Beomaster 1400K meets the wishes of the many listeners who insist on superb tonal quality and interference-free low-noise reception of stations outside the FM band. The razor-sharp selectivity of the Beomaster 1400K is a product of its numerous intermediate-frequency circuits. A further feature is a built-in short-wave expander for the SWII band, permitting you to 'spread' stations for maximum ease of tuning. There is a built-in decoder for reception of stereo broadcasts.

The amplifier of the Beomaster 1400K has very low distortion (less than 1%) at all frequencies and at all power output levels up to 2 x 15 watts. Its volume control circuit is physiologically compensated in the bass and treble ranges at low volume levels. A highly efficient balance control permits complete suppression of either channel at will. 

The Beomaster 1400K has two built-in pressure chamber speakers and jacks for two pairs of external speakers, switchable from the front panel. The gramophone input circuit incorporates a pre-amplifier which is easily replaceable to permit use of stereo record players both with and without pre-amplifiers. A tape recorder jack is also provided. Despite the vast amount of circuitry, cabinet dimensions are relatively small.

Dimensions: 112mm high, 744mm wide, 252mm deep. Choice of teak or Brazilian rosewood finish.

The set is identical with the Beomaster 1400K and has no built-in speakers.

The Beomaster 1400M replaced the Beomaster 900M. Though very similar in size, this new model represented a considerable advance over what had come before in all aspects.

The styling of the Beomaster 1400M was a departure from what was becoming normal B&O practice. Instead of being as slim and low as possible, the Beomaster 1400M assumed more conventional proportions, allowing for a large control panel and easy placement on shelving systems. The overall appearance of the set had been entrusted to a team of designers who usually worked with television sets, so it came as no surprise to find styling cues, such as the silver aluminium framing of the front of the set and the black ventilation grille across the rear, that were already present in the Beovision range.

The Beomaster 1400M matched its sturdy appearance with a really sturdy build. Much of the chassis and front panel was die-cast instead of pressed, something that one would not find anywhere else but the Beolab 5000 system. Internal layout was similar to that of the Beomaster 900, though advances in technique meant that not as much printed circuit area was necessary. The FM stereo decoder and the magnetic pickup equalising preamplifier were built as separate plug-in modules, though all Beomaster 1400Ms sold in the UK came with both fitted as standard.

Of all the technical improvements made, the most significant was an increase in the overall level of performance. With better circuitry and nearly three times as much power, the Beomaster 1400M fully meat the DIN 45 500 standard for Hi-Fi, something that was not the case for the 900 range. This better performance was in part due to the use of silicon transistors, as opposed to the germanium types used previously.

The Beomaster 1400M was well specified and included features such as four pre-set FM programmes, FM AFC, a tuning meter, a short wave fine tuner, two pairs of switchable loudspeaker sockets and a connection for a stereo tape recorder. It could be used as the main unit in a quality Hi-Fi system, with the Beogram 1000 record player and Beovox 2400 loudspeakers being the recommended first additions.
