Which of the following best explains the functions of the controls (Gain, Bass, Middle, Treble, Hi Presence, Master) that can be seen in the picture?

• They adjust the volume, tone, and presence of the audio signal in an amplifier.

• They control the power supply to the amplifier.

• They are used to switch between different audio sources.

• They are decorative knobs with no functional purpose.

What is the function of the 'Attack' control in a compressor?

• The 'Attack' control determines how quickly the compressor responds to the incoming signal once it exceeds the threshold.

• The 'Attack' control sets the output volume of the compressor.

• The 'Attack' control adjusts the frequency range being compressed.

• The 'Attack' control determines the amount of gain reduction applied.

What is the function of the 'Release' control in a compressor?

• The 'Release' control determines how quickly the compressor stops compressing after the signal falls below the threshold.

• The 'Release' control sets the input gain of the compressor.

• The 'Release' control adjusts the frequency response of the compressor.

• The 'Release' control determines the stereo width of the output signal.

What is the function of the 'Ratio' control in a compressor?

• The 'Ratio' control sets the amount of compression applied to the signal that exceeds the threshold.

• It adjusts the overall output volume of the compressor.

• It determines the frequency range affected by the compressor.

• It sets the attack time for the compressor.

What is the function of the 'Threshold' control in a compressor?

• The 'Threshold' control sets the level at which the compressor starts to act on the signal.

• It determines the frequency range the compressor will affect.

• It controls the speed at which the compressor returns to normal after compression.

• It adjusts the overall output volume of the signal.

What is the function of the 'Make-up Gain' control in a compressor?

• The 'Make-up Gain' control boosts the compressed signal to make up for any loss in volume caused by compression.

• It determines the threshold at which compression begins.

• It adjusts the speed at which the compressor reacts to signals above the threshold.

• It sets the ratio of input to output level for signals above the threshold.

What is the function of the 'Input Gain' control in a compressor?

• The 'Input Gain' control adjusts the level of the signal entering the compressor.

• It determines the amount of compression applied to the output signal.

• It sets the frequency range that the compressor will affect.

• It controls the speed at which the compressor releases the signal.

What is the function of the 'Output Gain' control in a compressor?

• The 'Output Gain' control adjusts the level of the signal leaving the compressor.

• It determines the frequency range the compressor will affect.

• It sets the speed at which the compressor starts to work after the threshold is exceeded.

• It controls the amount of compression applied to the input signal.

What is the function of the 'Stereo Link' control in a compressor?

• The 'Stereo Link' control links the left and right channels so that compression is applied equally to both.

• It increases the overall output gain of the compressor.

• It adjusts the attack time for only the left channel.

• It bypasses the compressor entirely.

Describe the function of an Oscillator in a synthesizer.

• An Oscillator generates the raw audio signal, usually in the form of a waveform such as sine, square, or sawtooth, which is the basis for sound synthesis.

• An Oscillator amplifies the audio signal to increase its volume before output.

• An Oscillator filters out unwanted frequencies from the audio signal to shape the sound.

• An Oscillator records external sounds to be used as samples in the synthesizer.
