RECA FINAL EXAM QUESTIONS WITH
CORRECT ANSWERS
What is the effect when you turn up the Q control on a Low Pass Filter really high? -
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? - 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 - Answer-True
What is a "Paragraphic Equalizer"? - 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

24db/Oct - Answer-24
What are other terms used for "Low Pass Filter"? - Answer-High Cut
LPF
What is a Filter? - Answer-A signal processor that can remove a specific Frequency
Band
What is a Frequency Band? - 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? - Answer-A Low Pass Filter
What does the Q parameter on an Equalizer control (multiple answers possible)? -
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? -
Answer-A Notch Filter
,Facts about Control Surfaces. - 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". - 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. - 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. - Answer-True
What is a FOH Mixer? - 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?
- 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? - Answer-Effects Sends
Headphone Mixes
Additional Outputs
How many Inserts Slots are available on a Channel Strip in Pro Tools? - Answer-10
What are the two most common on-board effects that you might find on a Chanel Strip
of a Hardware Mixer? - Answer-Equalizer
Compressor
What does DAW stand for? - Answer-Digital Audio Workstation
, What does the term Foldback stands for in a mixing console? - 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? -
Answer-You create a so-called "Resonance" that increases the frequency around the
Cutoff Frequency
The picture shows the Input Section of the API Legacy console. Which controls are
available? - Answer-Gain
Peak LED
Phantom Power
Attenuation
What is the main difference in Mixing Consoles used for studio recordings vs. live
sound? - Answer-The output of a live sound mixer goes to the PA system and the mixer
output for studio recording goes to a 2-track or multi-track recording device with an
additional output for the monitor speakers
Facts about Digital Mixers: - Answer-- Any audio signal will be converted to a digital
audio signal at the input using an Analog-to-Digital Converter
- All audio signal processing inside the console is performed digitally
- The audio signal has to be converted back to analog using Digital-to-Analog
Converters to listen to it
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 (indicated on
the x-axis). - Answer-True
True or False: The API Legacy Plus is a Split Console - Answer-False
Facts about Field Mixers for Electronic Field Production: - Answer-- Field Mixers have
sometimes recording devices built in
- Field Mixers are mostly battery powered
If a Channel Strip on a mixer has a switch labeled "Mic/Line" what does it do? - Answer-
It selects the input for that Channel Strip, either a microphone input or a line input
(Instrument)
Which are the three types of Modules that you can find on mixing console? - Answer-
Group Module
Input Module
