Hi!

Can you please offer some advice on how to go about measuring the
output voltages on my converters, gear etc. What exactly do I need to
do this? an RMS voltmeter?

Also, if I want to perform tests on preamps (S/N, THD+N, etc) , how do
I go about setting up a load on the input (simulate a mic connected).
Does anyone make a product, say an XLR with with user-selectable
resistance?

Appreciate your input
