Sound Exam #1

Name the three types of microphones AND tell me three unique things about each.

1. Dynamic

   • Uses a magnet

   • Has coil copper wire

   • most rugged

   • DOESN’T use Phantom Power

2. Condenser

   • Can be miniaturized to be used in a musical

   • NEEDS Phantom Power!

   • Responds faster than dynamic mics to rapid sound changes bc of its lower diaphragm mass and higher damping

3. Ribbon

   • Not used often & more fragile than the other 2

   • Thin metal foil is suspended in a magnetic field

   • Does NOT require Phantom Power

A 1/4” connector has two possible configurations:

TRS (Tip Ring Sleeve) or TS (Tip Sleeve)

A ___ type 1/4” connector has __ sections and can carry either a balanced mono OR unbalanced stereo signal.

TRS and 3

A ___ type 1/4” connector has __ sections and can carry only an unbalanced mono signal.

TS and 2

An XLR connector has __ pins and always carries a _____ mono signal.

3, balanced

Gain adjusts the __/__, allowing or restricting the amount of signal passing into the audio console.

amplitude/energy

EQ - Equalization is used to boost or cut specific _____ within a signal to achieve the desired sound.

frequencies

Reverb - Audio effect that mimics the

_____ _____ of an environment.

acoustic characteristics

Aux - Auxiliary sends allow proportional control of signal being sent from channels on an audio console out to ____ for _____.

monitors, performers

Channel

A single signal input on an audio console

What are the 5 parts of any (most) audio systems?

1. Source

2. Pre-Amp

3. Signal Processor

4. Amplifier

5. Speaker

Audio Cue in QLab

Allows you to play sounds over levels, directionality, and effects

Fade Cue in QLab

Fades an audio cue in or out. Used to make changes over time. It can fade levels, directionality, and effects.

Group Cue in QLab

Allows you to keep several audio and fade cues together. Functions like a folder to help organize and helps w/ playback of the stuff inside.

Active Speakers:

Have an amplifier built in, require a nearby plug for power, and usually have a volume knob. They’re generally easier to set up and are good for casual listeners.

Passive Speakers:

DO NOT have an amplifier built-in, require power from an external amplifier, and do NOT usually have a volume adjustment (attenuation). Give a more customizable sound experience but are harder to set up.
