OLUFSEN BM5
Little is documented about the "OLUFSEN BM5", and this page may be the first attempt to record anything at all. The name is suspicious. It doesn't match any known Bang & Olufsen model designation in standard references. The "OLUFSEN" spelling is likely a typo or variant of "Beolab" or another B&O line, but no source confirms that. It may have been meant as the B&O BM5 ribbon microphone, which Studio Sound (August 1970, p.34) reviewed. That one is a figure-of-8 stereo ribbon mic with a frequency response of 30 Hz to 13 kHz ±2.5 dB, coaxial up to 90°, and a sensitivity of 85 dB below 1 V/µB. The review also noted the mic's locking 5-pin plug/socket arrangement, and that its stand thread needed an adaptor for many standard stands.
The fact sheet for "OLUFSEN BM5" has no identity confirmation, no specifications, no history, and no product family placement. The research text supplied was blank. Nothing verifies that Bang & Olufsen made this model at all, and the production years, original price, and design details are unconfirmed. If the BM5 ribbon microphone is the intended subject, it is a real piece of B&O history, but no source ties the name to the product.
What the record shows, in short:
- No confirmed manufacturer, product type, or production years for "OLUFSEN BM5"
- No specifications of any kind are documented for this exact name
- A period review of a "BM5" ribbon microphone exists in Studio Sound (August 1970, p.34), but its connection to this listing is unverified
If you have a period brochure or service manual, the Archive would welcome the correction. Until then, this page is a placeholder.
