If you are planning an unusually large wedding, or perhaps a reception at a sizeable outdoor facility, additional sound reinforcement for a band or DJ may be required. Obtaining extra equipment should not be a problem, though it may mean a slightly higher entertainment fee. Unlike nightclubs, discotheques or live entertainment venues, it isn't necessary for the entertainment playing your wedding reception to be equipped with an elaborate light show. Excessive lighting can be distracting. Some effects are disturbing and annoying to older guests.
Lighting effects can also add significantly to the entertainment cost.
