Explain balanced connections
Can run long distances (500ft) 3 conductors Low impedance XLR Mic Good
Use this connection whenever possible
^ Tip (+) |_| Ring (-) | | Ground ---- | |
Explain unbalanced connections
Max 25 ft - interference if longer 2 conductors High impedance Instruments/ use direct box to fit it Laptops/iPhones 1/8" TS/TSR 1/4" TS Bad

1120 ft/sec
Frequency is measured in what?
Hertz/cycles/seconds
The further the wavelengths the ___ the pitch
Low
The closer the wavelengths the ___ the pitch
Higher
What is the frequency range the human ear can hear?
20 Hz to 20 K Hertz
Decibel is a measure of what?
Sound pressure/voltage
What is the decibel voltage level of a professional line level?
+48 dBv
What is the decimal voltage level of a consumer line level? Or instrument level
-10dBv
What is the decibel voltage level of a microphone level?
-55dBv
What do you use to increase the decibel voltage level?
The gain knob
What is the equalizer used for?
It adjust tone characteristics of sound to control
What is fundamental pitch?
The no you’re hitting or the loudest frequency
What is a harmonic frequency?
The aspect of sound waves that determine individual character of sound to an individual frequency
What is sound made up of?
Vibrating air
What does proximity effect do to your voice?
Increases low-frequency closer you get to the mic
When we hit solo (pre-fader listen button) on a channel what happens?
Takes a signal from the channel to expanded meter
What are the two kind of microphones?
Dynamic mic and condenser mic
Which type of microphone requires phantom power?
Condenser microphone
What is a transducer do?
Panthers one type of energy to another. for instance acoustic energy to electric energy
What is the voltage of phantom power?
48 V
What does the gain knob control?
Input level
What does the fader control?
Output level
