It is necessary to avoid ground loops. Just possibly you may get away with
it but I recommend you work out a way to isolate the BNC socket from the
box.
Also use an insulated audio jack.
Ground loops can really degrade the performance of these units with spurious
signals all over the place. just one ground connection to the computer. Use
an isolated PSU.
