I am going to be recording many tracks of orchestras and bands (the type with clarinets) and I am wondering which 48 channel mixer is going to be the best. I have about 15k in the budget for it. Looking for preamp/sound quality and overall quality and ease of use. I am liking the soundcraft ghost as well as the Mackie Onyx, which I know is not a recording mixer but it appears it will do the job. Any others I should know about? Advice on those? Thanks.
