RE: [Harp-L] Mic Impedance Transformer

["Bill Hines" <billhines4@xxxxxxxxxxx>]

I'd expect that you need a transformer from the sampson output to the
RP250 input, but the RP250 to the amp should be hi-z already if 1/4".
Make sure the sound guy or whoever plugs it into the *right* port on the
PA if you ever go that way, sometimes they will just plug into a vocal
mic port which is wrong.

i use it when plugging into my amp, a peavey bandit 112,
which is high Z, 250K Ohms.  adding the transformer made
a big difference in sound and volume.

i also use the fireball, without transformer, attached (XLR) to a samson
AX-1 wireless transmitter.  the output from the corresponding receiver
(samson concert 77) is a 1/4" output , but just 5K Ohms, going into the
input on my digitech rp250, which is 500K Ohms.  i expect i need a
transformer in that chain, as well.  i asked about that here recently,
but got no response.  haven't gotten around to picking one up.
