Typically, if we are providing sound for the ceremony and reception, we will arrive 2 1/2 hours before your ceremony starts to start setting up. It takes us about an hour to set up our reception sound system and it takes us about 20 minutes to set up the ceremony sound system (plus whatever time it takes for us to travel between the ceremony site and the reception site). For the ceremony, we would estimate sound check to be about 1 hour before your ceremony starts. For the reception, we would estimate sound check to be about 1 1/2 hours before you ceremony starts.
