Faders Flashcards
What are the three types of faders?
sliding potentiometer, VCA fader, digital fader
What happens in a sliding potentiometer?
amplitude of analog signals are represented by voltage, and resistance is used to drop it
What cannot happen with sliding potentiometers?
level boosting
What happens in a VCA fader?
fader only controls DC voltage sent to amplifier, no audio passes through
What is the advantage of a VCA fader?
many DC sources can be summed before feeding the VCA, resulting in less noise and a shorter signal path
What happens in a digital fader?
determines the coefficient value by which samples are multiplied (doubling sample value results in 6dB boost, halving attenuates by 6dB)
What should one set the level of first when mixing?
main instrument/vocal
