Sound
Desk Known as a P.A (Public Address system)
24 Input / Output sockets (Although this varies depending on the desk)
Mono & Stereo Channels
Can control all elements of the sound and can be used to manipulate sound.
‘Faders’ can be used to adjust the volume of each channel
‘Gain’ can be used to adjust depth of volume.
A ‘Peak Monitor’ can be used to determine the amount of volume sent to the speakers. (the GREEN lights must turn YELLOWsporadically, RED lights mean the frequency will become DISTORTED!
Reverb = amount of echo used (Reverberation).
Turn ‘Pan’ dials (Left dial turn left so that sound comes out the left speaker. right dial turn right so that sound comes out the rightspeaker.
‘EQ’ is used to change the different frequencies to make a voice sound more natural.
Desk Dials1. White = Gain (Controls amount of sound that goes
into desk).
2. Green = EQ (Used to make voices sound natural)
3. Red = Pan (used to control direction of sound to
speakers)

Compare & Contrast
Active Speaker Passive Speaker
Has a built in amplifier.
Only needs power source
Is considerably heavy.
I would use this speaker over the
Passive speaker as it does not need as
many wires with its built in amp and is
ideal for someone setting up a small
music gig because of this.
Needs a separate amp (as it is not built in)
Not as heavy.
I would use this speaker over the Active Speaker as this one would be better used higher up because it has an external amp on the ground meaning it can be controlled without needing to go up to the rigging.
