Full scale and -12db or -20db for Broascast ?

wouldn't it be nice if there was an international recording volume.

Just kidding.

lower the peaks.
broadcast hardware is generally set up at +8 for a OVU reference btw.(very hot)
compared to +4 (pro level) for recording studios.

As far as I recall, there are different standards for different parts of the world.
Down here, for tv (Oz), I will reference to K -20dB and record the test tone to -20dB and hover the program at 0 VU with peaks not going too far beyond that (definitely not more than 6dB). (note that you need the K-system reference meter for this. If you dont, you need to offset your values)
Radio, I use a -12dB K-system reference and ofcourse the rest of the details are as above... ie. It can be the same, because my meter reference is the key here.

Tip: If you have RME hardware, there are some great metering accessories that run on PC only unfortuantely. I use the 4 bar program meter all the time. It has the PPM in the middle and the respective L,R VUs on the outside of the PPM. (if I knew how to upload a piccie, I would).

The video guys love it, when you get all of this right and yes, your mixes on air will sound much better.
