Correct Answers
What are other terms used for a "Bell Shape" on an Equalizer? Correct Answer -
Peaking Filter
- Band Shelf
- Peak/Dip
What is an equalizer? Correct Answer A signal processor that can increase or decrease
the level of a specific Frequency Band.
What controls you might find on an Equalizer/Filter? Correct Answer Frequency
Gain
Shape
Slope
Q
True or false: An "Equalizer" is the same as a "Filter" Correct Answer False
True or False: When you have an Equalizer with a "Reciprocal EQ Response" and use
a Bell Shape, you get the same curve shape when increasing the Gain as when you
decrease the Gain, just inverted. Correct Answer True
What is special about an Equalizer with a Proportional Q Correct Answer In addition to
the value that you set manually with the Q control, the amount of Gain also affects the
actual Q Parameter. A higher ±Gain will increase the Q (Narrow Band) and a lower
±Gain will decrease the Q (Wide Band).
Which abbreviations you will find on an Equalizer? Correct Answer HMF
BPF
HPF
LPF
LMF
What device do you use to change the sound of an audio signal so it sounds like it
comes from an old telephone? Correct Answer A Band Pass Filter
What is the effect when you turn up the Q control on a Low Pass Filter really high?
Correct Answer You create a so-called resonance that increases the frequency around
the Cutoff Frequency
The steepness of a Filter can be described as" dB/Oct" or "Number of Poles":
6dB/Oct - 1 Pole
12dB/Oct - 2 Poles
,18B/Oct - 3 Poles
A 24 dB/Oct Filter has how many Poles? Correct Answer 4
True or False: The "Frequency Response Curve" shows how much the signal level on
the output of a device differs from its input signal, across all frequencies Correct Answer
True
What is a "Paragraphic Equalizer"? Correct Answer An Equalizer with many individual
Frequency Bands (like a Graphic Equalizer) that provides multiple controls for each
Frequency Band (like a Parametric Equalizer)
Which Filter Slope is steeper
6 db/Oct
24db/Oct Correct Answer 24
What are other terms used for "Low Pass Filter"? Correct Answer High Cut
LPF
What is a Filter? Correct Answer A signal processor that can remove a specific
Frequency Band
What is a Frequency Band? Correct Answer A specific range or section along the
frequency spectrum
What device do you use to change the sound of a disco song so its sounds like if
someone listens to it from outside the club? Correct Answer A Low Pass Filter
What does the Q parameter on an Equalizer control (multiple answers possible)?
Correct Answer - It alters the current steepness of a Filter curve set by its Slope
parameter
- It controls the range of the transition on a Low Shelf or High Shelf Equalizer
- It controls the Bandwidth of a Bell Shape Equalizer
What device do you use to eliminate a specific frequency, like a 60Hz ground hum?
Correct Answer A Notch Filter
Facts about Control Surfaces. Correct Answer - A Control Surface functions like a
remote control
- A Hybrid Mixer is a mixing console that lets you use its controls (faders, knobs) like a
Control Surface
- A Control Surface uses a specific protocol (i.e. EUCON, Mackie HUI) to communicate
with the device it is controlling
Facts about "Inserts". Correct Answer - On a hardware mixing console, an "Insert" is a
physical patch point where you can add an external signal processor to the signal path
of a Channel Strip
, - The "Insert" on a patch bay has usually two jacks, an "Insert Send" to send the signal
to the outboard signal processor and an "Insert Return" to connect the output of the
signal processor to the signal path of that specific Channel Strip
- An "Insert" on a DAW is usually a popup menu that lets you select a software effects
plugin to inserts into the signal path of a Channel Strip
Facts about Inline Consoles and Split Consoles. Correct Answer - Split Consoles and
Inline Consoles are mixers for multi-track recording
- An Inline Console has two separate audio signal paths per Input Channel Strip
- A Split Console uses separate Channel Strips for sending an audio signal to the multi-
track recorder and another Channel Strip to monitor the audio signal coming from the
multi-track recorder
True or False: A "Send Mute" is a separate Mute Button available on each Aux Send in
Pro Tools that is similar to an on/off button of an Aux Send found on the Channel Strip
of a hardware mixer. Correct Answer True
What is a FOH Mixer? Correct Answer A mixing console used for live sound placed in
front of the stage
What do you have to pay attention to when using the Mute Button on an Inline Console?
Correct Answer There are two separate Mute Buttons on a Channel Strip, one for each
signal paths (Small Fader, Large Fader)
What are Aux Sends used for on a Channel Strip? Correct Answer Effects Sends
Headphone Mixes
Additional Outputs
How many Inserts Slots are available on a Channel Strip in Pro Tools? Correct Answer
10
What are the two most common on-board effects that you might find on a Chanel Strip
of a Hardware Mixer? Correct Answer Equalizer
Compressor
What does DAW stand for? Correct Answer Digital Audio Workstation
What does the term Foldback stands for in a mixing console? Correct Answer Foldback
is another term for "monitor", describing the functionality of creating one or multiple
separate mixes for the musicians on stage
What is the effect when you turn up the Q control on a Low Pass Filter really high?
Correct Answer You create a so-called "Resonance" that increases the frequency
around the Cutoff Frequency
