It is on the output spots.

db refers to decibels. It is a logithmetric measure of relative signal strength, where 3 db is double and -3db is half. If the splitter is simply that -- i.e. a splitter -- I'd assume the 3.5 or 7 db refer to the decrease in output signal strength relative to the input signal despite the lack of the "minus". Some "splitters" are also powered amplifiers and can yield output signals higher than the input.

Most passive splitters do not have labels indicating db. Is that splitter powered (plugged into an electric outlet)? If so, the signal may be amplified and the two outputs represent different output levels. The 3.5 db as a positive number represents a gain of about 1.5 (50% increase in signal strength, while 7.5 db represents a gain of 2.4.
