var impedence.

For those happy with current pre but no var imp feature...never used but art have a new product called rp1.
it has a variable imp input. for ribbon and dynamic mics.
so one can go i guess as follows
mic to rp1 to next device in chain.
it also is a signal booster.
for more info see arts web site.

for other similar var imp gear and boosters.
just google. eg i just came across alctron ?
