“I just need a microphone and speaker for my event. Why do I need a mixer?”
Sometimes, we get asked why a mixer is included in our Basic PA System or Standard PA System – especially when all the client wants is a microphone.
The mixer serves the essential purpose of controlling the microphone’s volume (or for any other inputs connected to the mixer). It allows you to raise or lower the volume of the microphone over the sound system as needed.
No doubt, the mixer can be used to do many other things as well, but its most basic function is as a volume control – to raise and lower the volume of the devices attached to it.
And, despite all the fiddly knobs there are on the mixer, the main fader or knob that controls the volume (or “level” in technical speak). If it is a fader, pushing it upwards raises the volume and bringing it down lowers the volume. If it is a knob, turning it clockwise raises the volume while turning it anti-clockwise lowers the volume.
