I know by now this is an old thread so I don't know if the original posters are still checking it but I've got a quick question for Bennett, Evan or anyone who uses this. I noticed that the threshold on the c300 only goes to 0, as opposed to +12 or +20 db. With certain singers I find myself using a threshold of up to +5 or +10(rarely)on the 266xl. Has anyone found themselves wanting to to use a higher threshold than what is available on the C300? I've already got one on the way so I guess I'll find out soon enough but I was wondering if anyone has encountered this. Thanks.
