Details from a Decca promo leaflet:

** The top rack housed an 18 bit D/A converter for SPDIF, AES. The
second rack housed a 20 bit A/D which converted the studio line level
signal to digital data stream in the Decca format. SR 48kHz A signal
processing unit (euro card frame) that takes the digital data stream and
converts it into a signal that a modified video transport can record
(such as adding the various video sync pulses). It also generates
timecode and error correction data. Working simultaneously in record and
playback it also displays off-tape record level via a peak hold PPM. It
reads the off-tape timecode and monitors the overall quality of the
recording (by counting lost samples). It also has a limited amount of
system self-diagnostics.**

UKHHSoc would be interested in good scans of that leaflet. Would you be
willing to provide them or loan the leaflet?

BTW given the title of this thread people may find

of interest. It stems from a simple demo program I've written so that
people can experiment with DIY shaping 'high rez' files from 24 bit
down to 16bit in order to deal with the over-specifed 'noise' that
bloats FLACed versions
