How I Mix #4_Raising Faders
It's Newtons 3rd law, The Law of Inertia:
For every
action there is an equal and opposite reaction.
Raising the faders for a mix
requires a basic knowledge of levels. If you don’t know what the meters are
indicating, you may as well build our metaphoric house without using a tape
measure. Mixing music for mass distribution (broadcasting) means knowing more than red means
stop when it comes to reading audio level meters.
This link is
heady stuff. It needs to be understood by anyone wishing to deliver broadcast quality audio product.
I’ve tried
to make it easier more relatable here:
Zero dB marked on a fader plate can mean
different things depending on the intended use of the desk the fader is
interfaced too. Zero on a DSP desk measuring Full Scale (FS) would be on the top of the fader. Zero for a live desk would most likely be on the bottom of the
fader plate while zero on an analog recording desk would be two thirds the way up the fader plate. The latter two would indicate either dB-SPL or dBv respectively. Zero on a VU
meter indicates 1V dBv.
On the dB-SPL scale, the smallest audible sound (near total
silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times
more powerful than near total silence is 20 dB. It is called a logarithmic
scale. It is shaped like a bell …go figure.
