WHS. I'm pretty sure the meters on my tape decks, etc. all had a "0" setting around 3/4 of the way along. On the old mechanical ones the area behind the needle past that point was painted red; on the later electronic ones that was where the colour of the indicator lights changed from green to red. The zero point was where the best signal-to-noise ratio could be attained. Conventional wisdom said you tried to keep sustained recording levels below that point, but as close to it as possible; occasional (brief) peaks into the red were OK.
