Q

What part of a speaker is designed to handle high frequencies (2kHz-20kHz)?

A

The tweeter

17
Q

What part of a speaker is designed to handle the low and mid frequencies (100Hz-2kHz)?

A

The woofer

18
Q

What do some audio systems have to handle very low frequencies (below 100Hz)?

A

Sub-woofers

19
Q

What do some studios use for even greater accuracy?

A

Three-way monitors

20
Q

True or false: speakers are transducers?

A

True

21
Q

How can you tell the difference between the male and female end of an XLR cable?

A

The male end has pins, where as the female end has sockets

22
Q

What are the three pins on an XLR connector called?

A

Hot, cold and ground

23
Q

What can you do to increase the length of an XLR connection?

A

Connect multiple in a daisy-chain

24
Q

What are the two different sizes of jack connectors?

A

3.5mm and 6.35mm (or 1/4)

25
Q

What are the two types of jack connection?

A

TS (Tip-Sleeve) and TRS (Tip-Ring-Sleeve)

26
Q

How many wires do TS jacks consist of?

A

Two

27
Q

How many wires do TRS jacks consist of?

A

Three

28
Q

What type of connectors are XLR and TRS jack?

A

Balanced

29
Q

What do balanced connectors do?

A

They cancel out noise picked up as part of the cable run

30
Q

What is the cold signal of a balanced cable?

A

A polarity inverted version of the hot signal

31
Q

What does combining the hot and cold signals of a balanced cable mean?

A

The noise completely cancels out and the signal becomes twice as loud

32
Q

In a balanced cable, what does the ground wire do?

A

Protects against interference

33
Q

What are insert effects?

A

Processors that replace the original signal with a new processed signal

34
Q

What are send effects?

A

Processors that have two signals: the dry and the wet

35
Q

What are insert effects used for?

A

To add a processor or effect as part of the channel strip in series with a track’s signal

36
Q

What are send effects used for?

A

To route a track’s signal via another channel (a bus or auxiliary track)

37
Q

What processors do insert effects tend to be used for?

A

Gates, Compressors and EQs

38
Q

What are the most frequently and effectively used auxiliary effects?

A

Reverb and delay
