Acoustics, Monitoring, Leads And Signals Flashcards
What kind of room will be reflective?
A room with lots of hard surfaces
What kind of room will be least reflective?
A room with lots of soft surfaces
Finish the sentence: The more reflective the room, the longer the _______
Reverb time
What kind of room will have a longer pre-delay?
A larger room
What kind of room will have a shorter pre-delay?
A smaller room
On a reverb unit, what does the pre-delay allow you to do?
Alter the apparent room size without changing the reverb time
What can be used to ensure the accurate capture and monitoring of audio without unwanted colouration from the room?
Acoustic treatment
With regards to acoustics, what is absorption?
When the surface takes in some of the sound energy
With regards to acoustics, what does diffusion do?
Scatters sound waves from angled surfaces over a wide area
What can using acoustic treatment to control absorption, reflection and diffusion can help to solve what what issues?
Flutter echoes, standing waves, comb filtering
What can you do to make a room less reflective?
Add soft surfaces or acoustic treatment to the walls
What can reflections cause?
Cancellation or an increase in amplitude for a sound wave at a specific frequency
What can you do to increase separation between different instruments when recording them at the same time?
Use screens
What is the frequency response of studio monitors like?
Flat
What could happen if you mix on speakers that are not completely accurate?
Some frequencies will be reproduced louder or quieter than they should be
What part of a speaker is designed to handle high frequencies (2kHz-20kHz)?
The tweeter
What part of a speaker is designed to handle the low and mid frequencies (100Hz-2kHz)?
The woofer
What do some audio systems have to handle very low frequencies (below 100Hz)?
Sub-woofers
What do some studios use for even greater accuracy?
Three-way monitors
True or false: speakers are transducers?
True
How can you tell the difference between the male and female end of an XLR cable?
The male end has pins, where as the female end has sockets
What are the three pins on an XLR connector called?
Hot, cold and ground
What can you do to increase the length of an XLR connection?
Connect multiple in a daisy-chain
What are the two different sizes of jack connectors?
3.5mm and 6.35mm (or 1/4)
What are the two types of jack connection?
TS (Tip-Sleeve) and TRS (Tip-Ring-Sleeve)
How many wires do TS jacks consist of?
Two
How many wires do TRS jacks consist of?
Three
What type of connectors are XLR and TRS jack?
Balanced
What do balanced connectors do?
They cancel out noise picked up as part of the cable run
What is the cold signal of a balanced cable?
A polarity inverted version of the hot signal
What does combining the hot and cold signals of a balanced cable mean?
The noise completely cancels out and the signal becomes twice as loud
In a balanced cable, what does the ground wire do?
Protects against interference
What are insert effects?
Processors that replace the original signal with a new processed signal
What are send effects?
Processors that have two signals: the dry and the wet
What are insert effects used for?
To add a processor or effect as part of the channel strip in series with a track’s signal
What are send effects used for?
To route a track’s signal via another channel (a bus or auxiliary track)
What processors do insert effects tend to be used for?
Gates, Compressors and EQs
What are the most frequently and effectively used auxiliary effects?
Reverb and delay
