Beocord 900 was the simplest of Bang & Olufsen’s range of cassette-recorders.
Your only task was to choose the type of tape to put in: Cr02 or normal. Beocord 900 had large easy-to-read VU meters and recording controls were separate for left and right channels. There was a socket for a microphone and a push-button for mono recordings.
Tape-heads were made of Super Permalloy, a hard and extremely durable material which ensures a long useful lifetime. Wow and flutter was less than 0.28% (JIS method). Signal-to-noise ratio was better than 50 dB with chromium dioxide tapes.
