best loudness range for short film.

Hi Post wizards



I am a music engineer, not a re-recording mixer.



I am helping out a pal on a zero budget, short film. The sound of the film is very very simple, and not very dynamic. The film will live various places (internet, festivals, etc)



I need to know a safe range for final audio levels.



I am going to buy TC Electronic LM1n ($50 on sale) or LM2n ($99 on sale)



May I ask what is a safe ballpark for levels for me to hand off?



I am unfamiliar with the scales used in the LM1n / LM2n, so assume you are instructing a talented cat. ;-)



Thanks
