This popular microphone is a dynamic, matte-black Shure used to mic up snares, guitar amps, and almost anything!
What is the SM57?
Commonly referred to by the acronym "PA," this system is comprised for microphones, amplifiers, and speakers.
What is a Public Address system?
Frequency is measured in these units.
What is Hertz?
This type of signal moves over copper cable.
What is analog signal?
This component is used to proportionately reduce the dynamics of a signal that goes above a defined threshold.
What is a compressor?
"I've got the power!"...to power condenser microphones and active DIs, and typically at this number of volts.
What are 48 volts?
This type of cable has three pins - positive (hot), negative (cold), and ground/shield.
What is an XLR?
The amplitude of a wave is measured in these units.
What are decibels?
A regular XLR cable carries this kind of signal.
What is analog signal?
This type of EQ allows the user to select the bandwidth for the frequency that they're affecting.
What is a parametric EQ?
This type of microphone picks up acoustic sound from the front and back, but not the sides.
What is a bidirectional microphone?
If a speaker does not have the ability to power itself with an internal amplifier, it is this type of speaker.
What is a passive speaker?
The speed of sound in feet per second - also known as its velocity.
What is 1130 ft/sec?
CAT5, CAT5e, Fiber Optic, and AES/EBU are all types of of cables that can carry this type of signal.
What is a digital signal?
This letter is used to describe the bandwidth on a parametric EQ.
What is "Q?"
This popular type and brand of microphone is often used for "kick in."
What is the Shure Beta91 / 91a?
This kind of speaker configuration hangs from a rigging point, with speakers attaching to each other vertically.
What is a line array?
This is what we call the distance between sound wave peaks.
What is the wavelength?
The snake between a Behringer X32 and a Behringer S16 stage box is this type of snake.
What is a digital snake / CAT5/CAT5e snake?
This device will cut off a signal if it falls below the user-defined threshold.
What is a gate?
This is the type of mic used to measure and analyze the frequencies that a PA is emitting.
What is a reference/RTA (real-time analyzer) microphone?
This is what the delay in signal from input to output causes.
What is latency?
This is the formula for Ohm's Law, which is used to calculate voltage.
V = IR
(Voltage = Current x Resistance)
Fiber Optic cables are made of this material tightly wound together.
What is glass?
This is the name for where the signal is split into two or more frequency ranges in a system.
What is the crossover?
