Description
The Mk6 appeared around
1971, and I suspect was mainly a cosmetic update on the STB, utilising
the same three motor deck and pressure pads. However, it had a larger,
dynamically balanced flywheel to minimise wow & flutter which in fact
gave a slightly better set of figures than the STB.
The unit could be used in the horizontal or vertical position and had
two large-scale illuminated edge-style meters that were very similar to
the earlier STB.
Mixing between microphone and auxiliary inputs and cross fading was possible,
and A/B switching (comparison of recording with original signal) was available
for the first time on a Brenell.
By the time this model appeared in Australia, it was considered to be
‘dated’ ..
A detailed period test report for this recorder is supplied on the Get
Reel Contemporary Classics CD-ROM.
