Hello guys , this is my first outboard rack ever.i want to connect it to my mackie 1604cr mixer, the manual is quite clear but i have few questions about. Is going to be a parallel setup, pretty easy to do, but i'd like to know if is better use balanced or unbalanced cable from the send/return of the mixer to the xlr in out of the lexicon. 2nd question, this reverb can be used as a vst hardware. I wonder if i can have the reverb connected in spdif to use it as vst and at the same time having it in parallel on my mixer. Thx in advance for your help!
