I need to use 2 lav mics as well as the onboard. I've been playing with the channel and input selections, but can't figure out the right combination. The lav mics are more important, so I'd like to be able to control those levels. I'll be recordiing in 1080i / 24P. I see in the Recording Setup --> 25M REC CH SEL it's blue and on 2CH. I'm thinking that's the culprit, as I need the 4 channels. Any direction greatly appreciated. Thanks!
