Hi, i wonder if someone could help me with my Vandergraph.
I can't figure out why it makes such a noticeable hiss when turned on.
I got gain all the way down, but when I switch on any of the ratios, the hissing starts. I've tried various cables, different inputs and outputs from analog mixers to a few different interfaces, to no avail.
Even when I connect the outputs from my Vandegraph -without anything on the input- to my SSL Six mixer, the hissing is there (xlr, jack, no matter). I'm using an Heritage Audio OST-4 as the chassis, but couldn't find Vandergraph's power requirements anywhere; the Heritage rack supplies 400mA per rack. There's no hiss with the two other 500 pieces I have.
Is it just part of the way it operates, increasing the levels that drastically even without any gain?
I'm new to both the machine and 500 series, and I'm afraid this must be such a dumb question with the answer right in front of me, but spare me for I did try searching for an answer and trying out all possible combinations before coming here to cry for help.
Cheers!
