False
When using a wireless microphone system, which of the following responsibilities must be communicated clearly between user and operator?
Who is in control of the mute and/or on and off switch
what government agency publishes noise level exposure guidelines?
OSHA
Which of the following terms describes an artificial bass boost experienced when a directional microphone is moved closer to a sound source?
proximity effect
Which of the following microphone technologies is least likely to be found on a live stage?
ribbon
Which of the following mic techniques is the least mono-compatible?
spaced pair
What is amplitude?
the maximum height of a waveform or sound pressure wave
Custom molded in-ear monitors provide better isolation than universal fit in-ear monitors
true
Solo In Place (SIP) on a mixer mutes all other signals to the main mix and its use should be be avoided during a live event
true
T/F: A fundamental role of a sound operature is to prevent distractions during a performance
true
T/F: According to class, professional rechargeable batteries (not off-the-shelf) are the best choice for wireless microphone systems
true
T/F: An important consideration for sound operators is the behavior of sound waves in a space as they reflect off of boundaries and interact with each other
true
T/F: Cardioid subwoofers are setup to control the distribution of low frequency energy in a venue
true
T/F: Most wireless microphone systems require a clear line of site for ideal operation
true
T/F: The insert function on a mixing console requires the use of a special cable
true
T/F: Transient response is the ability of a microphone to capture fast variations in amplitude
true
T/F: Wireless in-ear monitor systems require two antennas for transmitting the signal in order to combat multi-path issues
true
T/F: the behavior of sound waves in a space as they reflect or bounce off of boundaries and interact with each other is an important consideration for sound operators
true
T/F: the location of the vocalists hand on the microphone has a significant impact on the quality of the sound picked up
true
T/F: the sound emanating from multiple loudspeakers outputting the same (or very similar) audio signal will arrive at a listener's ears at different times, causing a phase shift, and consequently, a frequency content shift known as comb filtering.
true
T/F: In-ear monitors require a unique approach to EQ when it comes to the performers voice
True
