Making the Most Of Your Mixer A Place For Everything and Everything In Its Place 1 1-1. A Plethora Of Connectors—What Goes Where? Questions you’re likely to encounter when setting up a system for the first time might include “Why all these different types of connectors on the back of my mixer?” and “What’s the difference?”. Let’s start by taking a look at the most common connector types. The Venerable RCA Pin Jack This is the “consumer connector,” and the one that has been most commonly used Whi

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

Making the Most Of Your Mixer 1-3. Signal Levels—Decibel Do’s and Don’ts From the moment you start dealing with things audio, you’ll have to deal with the term “decibel” and its abbreviation, “dB”. Things can get confusing because decibels are a very versatile unit of measure used to describe acoustic sound pressure levels as well as electronic signal levels. To make matters worse there are a number of variations: dBu, dBV, dBm. Fortunately, you don’t need to be an expert to make things work. He

Making the Most Of Your Mixer The First Steps in Achieving Great Sound 3 Before you even consider EQ and effects, or even the overall mix, it is important to make sure that levels are properly set for each individual source. This can’t be stressed enough—initial level setup is vitally important for achieving optimum performance from your mixer! Here’s why … and how. 3-1. The Head Amplifier “Gain” Control Is the Key!

If you take another quick look at the mixer block diagram you’ll notice that there’s a peak indicator located right after the head amplifier and EQ stages, and therein lays our answer! Although the exact procedure you use will depend on the type of mixer you use and the application, as well as your personal preferences, here’s a general outline: Start by setting a

If you have a group of channels that need to be adjusted all together while maintaining their relative levels, grouping is the way to go. Simply assign the group to a group bus, and make sure that group is also assigned to the main program bus. Then you can adjust the overall level of the group usin

The channel inserts are almost always located before the channel fader and, when used, actually “break” the mixer’s internal sig- nal path. Unlike the AUX sends and returns, the channel insert only applies to the corresponding chan- nel. Channel inserts are most commonly used for applying a dynamics processor such as a compressor o

If you set the switch on ( ), the mixer sends the pre-fader signal (the signal prior to passage though channel fader A) to the AUX1 bus, so that AUX1 output is not affected by the fader. If you set the switch off ( ) the mixer sends the post-fader signal to the AUX1 bus. Note that this switch applies to AUX1 only. The signal to the AUX2 bus always passes through the channel fader first.
