| Re: Low response level from REW to RS meter. Are you using a line-in or a mic input for connection of the SPL meter? When I first tried the REW with a laptop I soon found similar problems with not having a line-in on the laptop. Dragging my trusty desktop into the equation "solved" the "level" problem by connecting to a line-in and not mic input. FWIW I found having the RS meter on 80db range the best for the readings into the REW.
