This polar pattern has a 180° heart-shaped acceptance sensitivity from the front of the capsule.
What is cardioid?
This cable is used for low-z, or mic-level signals and connects microphones to consoles or snakes.

What is XLR?
This kind of speaker requires an external power amplifier.
What is a passive speaker?
In order to match a speaker to an amplifier, the amplifier must be able to output this amount of wattage compared to the speaker.
What is at least 1.5-2x?
Accepting sources from all sides, this polar pattern is "all-emcompassing"
What is omnidirectional?
This product creates cleaner cable management, and allows multiple inputs from the stage to reach the console in an easier fashion.

What is a subsnake?
This type of driver reproduces the lowest frequencies
What is a subwoofer?
Current is measured in this unit.
What are Amps?
This polar pattern has an acceptance angle of 150° and is good for capturing a very direct sound source.

What is supercardioid?
If you see this type of input adapter on the back of an active speaker, either of these two categories of cables can be plugged in.

What are XLR and 1/4"?
Speakers that include three unique types of drivers are referred to as this.
What is three-way?
What is increases?
This frequency response chart denotes a microphone that is designed to capture this frequency group.

What is low-frequency?
When considering "Mic" and "Line"-level sources, this source has the most impedance.
What is Line-Level?
Like the microphones, these types of speakers include a magnet, a voice coil, and a diaphragm to reproduce sound.

What is a dynamic speaker?
If speakers are wired in parallel with the same impedance ratings, we find their total impedance by doing this.
What is using the impedance rating and dividing by the number of speaker components?
