Burwen Noise Eliminator
Single-ended noise reduction unit, 1970s. Dynamic noise filter: a low-pass filter whose cut-off moves with the high-frequency content of the programme, closing down to hide hiss when the music is quiet or dull. A hi-fi noise filter that needed no encoding, so it worked on any source.

noise reduction
Single-ended noise reduction that lowers steady hiss on a finished recording, the same job this unit did; it is not a model of this unit.
