Homework 3 Flashcards
What are 2 purposes of equalization on a mixer channel?
1) to get rid of (cut) part of the tone that we don’t want, and
2) to enhance (boost) some part of the tone that we do want
What are 2 other names for the EQ section?
Tone control, highs and lows, or highs, mids and lows
How do we piece things together like a puzzle with EQ on each instrument?
Boost and cut different frequency ranges on different instruments (keep the big picture in mind)
What is the range of frequencies that the human ear can hear?
20 Hz to 20,000 Hz
What frequency is “sub-bass”?
Below 60 Hz
What frequency range is “Bass”?
60-250 Hz
What frequency range is “Low Midrange”?
250 Hz - 1.5 kHz
What frequency range is “High/Upper Midrange”?
1.5-3.5 kHz
What frequency range is “presence” found?
3.5-6 kHz
Define what the Bandwidth knob does on a parametric EQ
Chooses whether you’re cutting or boosting a large range of frequencies or a very specific range of frequencies
What defines a fixed EQ?
The range is set and not as flexible, no selectable frequency
What defines a Sweepable EQ?
Dramatically increased the flexibility of sound shaping. Has a cut/boost control to turn selected frequency up or down, and a frequency selector that lets you sweep a certain range of frequencies
Another name for Bandwidth is __?__?
The Q
What is the difference between a semi-parametric and fully-parametric EQ?
Parametric gives you control of the bandwidth (Q) and semi-parametric is just the frequency
What is the different about a Graphic EQ?
It’s the most visually graphic of all EQ’s, makes it obvious at first glance which frequencies you’ve boosted or cut, has 10 more sliders
Define High Pass Filter
Let’s high frequencies pass through and cuts the low frequencies
Define low pass filter
Let’s low frequencies pass through and cuts the high frequencies
Define shelving EQ Filter
Leaves all frequencies flat to a certain point, then turns all frequencies above or below that point down or up at a rate specified in dB per octave
Define Bell curve EQ filter
When you boost/cut a particular frequency, it also does the same to frequencies nearby. The exact range of frequencies boosted/cut is dependent on the shape of the curve
What frequency range are highs?
Above 3.5 kHz
What frequency range are Mids?
Between 250 Hz and 3.5 kHz
What frequency range are lows?
Below 250 Hz
