Bang & Olufsen Beomaster 900 (1975–1979)
The Beomaster 900 (Type 2949) is a receiver introduced in autumn 1975, replacing the earlier Beomaster 1200 series. It was designed as a companion piece to the Beovision 1500 television, which could be placed on top of the amplifier and share its power output — an integrated approach typical of Bang & Olufsen's system-thinking of the period. Production ran through 1979.
The amplifier is rated at 2 x 22 watts RMS into 4 ohms (20 W per channel into 8 ohms), with a frequency range of 20–20,000 Hz and distortion listed at 0.09%. It offers high-level inputs only — two pairs of input jacks — with no phono stage built in; instead, the rear panel carries two slots for optional modules, including phone (SP 900), tape, and microphone preamplifier cards. Two pairs of speaker terminals are provided. Tone controls are limited to bass and treble. The unit weighs 5.3 kg and measures 48 cm wide, 8.3 cm high, and 27 cm deep. Finish options were rosewood or walnut. The original Danish price was DKK 2600 without speakers.
Period advertising in Studio Sound (September 1967, p.10) positioned Bang & Olufsen as a maker "for those who consider design and quality before price" — a tagline that carried into the Beomaster 900's era, though the receiver itself appears to have received little in the way of formal review coverage. A service note from Beoworld offers one candid piece of reception history: "The Beomaster 900 was an absolute nightmare to work on!" — a technician's sentiment that suggests the sleek, low-profile chassis came at a cost in serviceability.
Surviving documentation on the Beomaster 900 is otherwise thin. No tuner sensitivity figures, signal-to-noise ratios, or detailed module specifications are recorded in the sources consulted.
