Is anybody out there using 1 or 2 space rack mount line level mixers? What do you think of what you have and what should I look into? Right now I have a patchbay and a Rane SM-26(?) - an 8 line mixer with no effects sends. After reading about DT's setup I am considering the possibilities of having effects sends in a mixer, rather than through the use of a patchbay. Any thoughts?
