[QuadList] Audio and Time Code Quiz of the week

You are correct as to the level.  +3 db.  The reason being that SMPTE time code is a square wave.  Thus the RMS energy is higher by that amount.  The peak to peak level is the same as a sine wave that shows 0 db on the meter.

That answers the first part of the questions.
