Basic terminology

Question 1

Analog Signal

Answer 1

audio wave transduced into alternating voltage

Question 2

Digital signal

Answer 2

voltage reading sampled from analog signal stored as bits

Question 3

PAD

Answer 3

reduce level of signal input prior to preamp - prevents overloading from high signals

Question 4

low cut/high pass

Answer 4

reduce loudness of low frequencies

Question 5

Line signal level

Answer 5

stronger signal from mixers (1 volt)

Question 6

Mic signal level

Answer 6

weaker signal from microphones (0.01 volt)

Question 7

Pre-Amp

Answer 7

boost mic level signal to line level

Question 8

Sampling

Answer 8

measurement of voltage of signal at a specific point in time

Question 9

Sample rate

Answer 9

samples per second - for frequency

Question 10

Bit rate

Answer 10

values available to assign to sample - for volume

Question 11

what does a field mixer do?

Answer 11

Portable device - for managing and mixing multiple audio sources

Question 12

What do we use the 1K test tone for?
