I just purchased a Sennheiser G2 wireless mic package. When setting the output level of the Sennheiser receiver, should it be "mic" level (with DVX input at "mic"), or should it be at "line" level (with DVX input at "line")? When tweaking this adjustment, should I have the audio level knobs on the dvx set to about the middle and adjust Sennheiser receiver output until audio just peaks into red region (on level meters in dvx screen)? Thanks much!
