Week 4

Question 1

Effected

Answer 1

A sound signal that has had one or more effects applied to it.

Question 2

Electromagnet

Answer 2

An electromagnet is created whenever an electrical current flows through a wire. If the wire is coiled and wound around a metallic material, the magnetic field is strengthened. Loudspeakers and microphones use electromagnetic effects to convert sound to electricity and back again.

Question 3

EQ

Answer 3

Equalisation is the process of filtering, amplifying or attenuating a range of frequencies in an audio signal. Usually in frequency bands such as Bass, Mid, or High.

Question 4

Fader

Answer 4

A linear or rotary control, most commonly found on a mixer to adjust the volume of each channel.

Question 5

Foldback

Answer 5

A signal sent to monitors on stage or headphones in a studio to enable performers to hear themselves and other pre-recorder or live signals.

Question 6

Frequency

Answer 6

The number of cycles per second, either in a sound wave or electrical audio signal.

Question 7

Frequency response

Answer 7

The sensitivity of audio equipment (such as microphones or loudspeakers) at different frequencies, often presented as a chart. A ‘flat’ response suggests a similar sensitivity across a range of frequencies.

Question 8

Gain

Answer 8

A measure of amplification. For example, an amplifier may have a gain of 10, meaning that the output will be 10 times larger thatn the input. This is sometimes represented in decibels. Gain controls are commonly seen at the top of a mixer channel, controlling the channel preamp.
