Making the Most of Your Mixer

You’ve got yourself a mixer and now you’re ready to use it.

Just plug everything in, twiddle the controls, and away you go … right?

Well, if you’ve done this before you won’t have any problems, but if this is the first time you’ve ever used a mixer you might want to read through this little tutorial and pick up a few basics that will help you get better performance and make better mixes.

Balanced, Unbalanced—What’s the Difference?

In a word: “noise.” The whole point of balanced lines is noise rejection, and it’s something they’re very good at. Any length of wire will act as an antenna to pick up the random electromagnetic radiation we’re constantly surrounded by: radio and TV signals as well as spurious electromagnetic noise generated by power lines, motors, electric appliances, computer monitors, and a variety of other sources. The longer the wire, the more noise it is likely to pick up. That’s why balanced lines are the best choice for long cable runs. If your “studio” is basically confined to your desktop and all connections are no more than a meter or two in length, then unbalanced lines are fine—unless you’re surrounded by extremely high levels of electromagnetic noise. Another place balanced lines are almost always used is in microphone cables. The reason for this is that the output signal from most microphones is very small, so even a tiny amount of noise will be relatively large, and will be amplified to an alarming degree in the mixer’s high-gain head amplifier.

	Balanced noise cancellation			To summarize
		Noise		Microphones:	Use balanced lines.
		Hot (+)		Short line-level	Unbalanced lines
				runs:	are fine if you’re in a
		Cold (–)			relatively noise-free

					the ultimate

					balanced is best.

A mixer may be required to handle signals at a wide range of levels, and it is necessary match input and output levels as closely as possible. In most cases the “nominal” level for a mixer’s input and outputs is marked on the panel or listed in the owner’s manual.
