2) Is factual info
Term
What is Dynamic Range?
Definition
The range of volume level between minimum and maximum of a signals amplitude
Term
What is Potentiometer?
Definition
It is a variable resistor that controls the flow of energy between minimum and maximum
Term
What is a switch?
Definition
Cuts or turn-on on/off
Term
What are the 3 systems of a console/board?
Definition
1- Input/pre-amp (its a potentiometer)
2- Output/Bus ( A signal combiner and transporter)
3- Monitor
Term
What is a Pre-amp?
Definition
It amplifies a signal
Term
What is a capacitor/Condenser?
Definition
Stores an electrical charge
Term
what is phase reverse?
Definition
The reverse phase switch does is it takes one of the stereo channels and switches the positive to the negative, and the negative to the positive
Term
what is phantom power/48v
Definition
-provides power to a signal
- its a switch
Term
what are the 2 types of inputs that goes to a console/board?
Definition
-mic
-line
Term
What is line input?
Definition
output signal of devices plugged into the wall (ex. compressor, flanger, echo, reverb)
Term
What is a parameter?
Definition
Any variable adjustment used to alter a signal
Term
What is resistance?
Definition
To limit the flow of electricity
Term
What is DI?
Definition
-Direct input
-Conducts Hi-z or lo-z impedance (limit) on a signal
Term
What is a Pad?
Definition
-Switch
-Cuts the level of a signal to prevent overload
-Use only when the pre-amp is in its minimum position
Term
What is Bass roll-off/High pass filter?
Definition
-Its a switch
-The low and mid range frequencies below the cut-off is removed and hi end freq pass
Term
Name 4 things that are used by the Pre-amp?
Definition
1) DI
2) Pad
3) Phantom power
4) phase reverse
Term
What is a bus?
Definition
A signal combiner and transporter
Term
What is a stereo bus?
Definition
The line output, consists of the L and R
Term
whats a Pan-pot?
Definition
Panning; controls the flow of electricity between the L and R bus output
-Aka Panoramic potentiometer
Term
what is a low-pass filter?
Definition
Lets the low-freq pass and removes the mid and hi range freq
Term
What is a band pass filter?
Definition
Cuts the lo and hi range freq and focuses on the mid range
Term
What's a monitor system?
Definition
Controls the speaker and headphone output
-its a potentiometer
Term
What is the sound frequency spectrum?
Definition
20hz-20khz
Term
What is Impendence?
Definition
To limit, and measured in Omes
Term
What is proximity effect?
Definition
Is the increase of bass frequencies as a microphone comes closer to the sound source
