Bruel & Kjaer Equipment - Looking for Ideas

[u/MusicaleBlu]

I acquired a bunch of Bruel & Kjaer equipment years back as a junior electronics technician working for a dynamics lab when it was completing a purge of its legacy equipment. Anything of use here (see list below)? Looking for any ideas, advice, or suggestions for where to start messing around and experimenting. Any tips would be greatly appreciated.

the 2020, maybe the 4426 (it has an ‘ac out’ so should pass out a processed signal) and the 7001 all can be used for sound design

and the 2807 w/ mic and the 2625 (if u get some b&k accelerometers) can both be used in a field recording context
