AET 2560 - Sound Reinforcement Final
UPDATED Actual Exam Questions and
CORRECT Answers
illegal frequency bands - CORRECT ANSWER✔✔- 100 - 799 mHz
squelch - CORRECT ANSWER✔✔- a circuit for preventing a radio receiver from producing
audio-frequency output in the absence of a signal having predetermined characteristics
diversity receiving - CORRECT ANSWER✔✔- two antennas switching systems to pick up
strongest signal from antenna
difference between limiting and compressing - CORRECT ANSWER✔✔- compressor: a
signal processor that for a given input amplitude range produces a smaller output range
limiter: a signal processor in which some characteristic of the output is automatically
prevented from exceeding a predetermined value
side-chain input on a compressor - CORRECT ANSWER✔✔- input to the gain reduction
stage of circuit
allows external audio source to control gain reduction
gate - CORRECT ANSWER✔✔- attenuates signals that register below the threshold; the gate
opens when signals pass the threshold
downward expander - CORRECT ANSWER✔✔- when the signal level drops below the
threshold, the signal gain is decreased
notch filter - CORRECT ANSWER✔✔- a band-stop filter with a narrow stop band (high Q
factor)
, advantage of using stereo input channel over a reverb return - CORRECT ANSWER✔✔- ...
parametric EQ - CORRECT ANSWER✔✔- provides both sweepable center frequencies and
adjustable Q, as well as boost / cut controls
semi-parametric EQ - CORRECT ANSWER✔✔- provides control of the amplitude and
frequency, but uses a pre-set bandwidth of the center frequency
non-parametric EQ - CORRECT ANSWER✔✔- ...
graphic EQ - CORRECT ANSWER✔✔- multi-frequency, band reject filter, or a band-pass /
reject filter
LPF - CORRECT ANSWER✔✔- low-pass filter; passes low-frequency signals and
attenuates signals with frequencies higher than the cutoff frequency
BPF - CORRECT ANSWER✔✔- band-pass filter; passes frequencies within a certain range
and attenuates frequencies outside that range
HPF - CORRECT ANSWER✔✔- high-pass filter; passes high-frequency signals but
attenuates signals with frequencies lower than the cutoff frequency
threshold - CORRECT ANSWER✔✔- certain dB point at which a compressor reduces the
level of an audio signal if its amplitude exceeds that point
ratio - CORRECT ANSWER✔✔- amount of gain reduction
4:1 means that if input level is 4 dB over the threshold, the output signal level will be 1 dB
over the threshold; the gain (level) has been reduced by 3 dB
attack - CORRECT ANSWER✔✔- period when the compressor is decreasing gain to reach
the level that is determined by the ratio
