Signal Processors

The release time on a compressor:


a)  is useless if signals never drop below threshold

b)  determines how quickly gain reduction commences

c)  determines how much gain reduction occurs

d)  helps maintain an even dynamic range over the entire range


Signal Processors

A broadband de-esser:


a)  filters the presence range from the program

b)  compresses the presence range

c)  compresses the program when the presence range exceeds a threshold

d)  compresses the presence range when the program exceeds a threshold


Signal Processors

A downward expander has an input signal that ranges from -10 dB to +10 dB.  The threshold of expansion is set at 0 dB and the ratio is 1:4.5, what would the output dynamic range equal?


a)  45 dB

b)  50 dB

c)  55 dB

d)  65 dB


Signal Processors

“Manual” compression is known as:


a)  limiting

b)  expansion

c)  dbx

d)  gain riding


Signal Processors

The modulation section of a delay line:


a)  allows the delay level to be changed

b)  allows the phase of the delay to be reversed

c)  changes the delay time with relation to an LFO

d)  changes the delay time according to the input level


Signal Processors

A device whose output gain decreases as its input level (above the threshold) increases could be a:


a)  compressor

b)  downward expander

c)  expander

d)  gate


Signal Processors

When recording a snare drum the meter shows a maximum level of 0 Vu, but the peak light comes on with each beat, an appropriate setting on a compressor would be:


a)  threshold at +4 dBu, 2:1

b)  threshold at +10 dBV, 8:1

c)  threshold at -10 dBu, 6:1

d)  threshold at -20 dBu, 4:1
