AAERT CER COMPREHENSIVE TEST PAPER
WITH SOLVED QUESTIONS
◉ Digital mixer
Answer: A device that takes a signal through a cable to a
computer. In other words, it takes sound in the form of an analog
signal from the microphone(s), converts the analog signal to a
digital signal, and transports that signal to a computer. Digital
mixers are sometimes referred to as audio interfaces
◉ When choosing digital mixer
Answer: Make sure the mics chosen are compatible and that your
computer has a connection port that can receive the output. Also,
make certain digital recording software you are going to use is
compatible with the mixer. Choose software before mixer.
◉ Mixer input types
Answer: Microphone, instrument, and line.
◉ Microphone input connection
Answer: Usually XLR but can also be TRS
◉ Microphone preamps
, Answer: Any microphone input that also offers a preamp will
significantly boost the signal strength of the audio for that
channel.
◉ Output types
Answer: You will most likely see digital mixer outputs either as
USB or FireWire (IEEE 1394). There are some cases where a serial
connection my still be used, but that type of connection is not as
common
◉ Phantom power
Answer: Sends 48V power to the XLR inputs for use with
condenser microphones requiring external power
◉ Front and rear microphone switches
Answer: Digital mixers will oftentimes have a combination of
inputs on the front and rear panels. All systems are different.
There will usually be a switch that selects the appropriate inputs
for the analog audio channels
◉ Gain pad
Answer: Controls that adjust the level input gain for the analog
audio channels on the mixer
◉ Capture
