I have a Zoom h4n and rode shotgun videomic. I just want to know, how others setup their audio system.
Im thinkin of having another wireless lav as well.

Can you guys (if theres any) at least show a picture of your setup ?

I put a wireless lav on the groom and use a camera - mounted shotgun mic. Sometimes I put a zoom somewhere up the front, but I've never had to use the audio from it.

This has been discussed many times. I would suggest a search in the Wedding and Event forum.

Groom gets a mic and backup, all podiums/mics get another, all music (overall) gets a mic, and all additional speakers as applicable. Typically 5-7 mics depending on event particulars and type of ceremony. Basically, whomever talks will get a mic unless they personally decline it.

I found two wireless lavs and a Zoom H4n is more than enough. I place a wireless lav on the official and groom and use the Zoom H4n for musicians or where ever sound needs to be recorded. I always shoot with two cameras so one camera is getting sound from the wireless lavs and the second camera records on-board.
