Mixing #3: The Mixer Part 2

Welcome back, I hope all is well and that you are beginning to understand more about mixing. Well, in the last article I broke down some basic mixer functions. So far we went over inputs and we took a look at the channel strip. Today’s article is shorter and will deal with Insert and Send functions. After this we will move on to discuss Busing which is also known as Routing. If you need to refresh your memory on the last lesson, simply go back and read Part 1 before you go any further here. But if ur all gud then let’s jump on in it!

Inserts

Returning our attention to the channel strip, let’s check out the insert function. This is a place where things really begin to take on more shape and character. Why? Because…. The insert area allows you to use specific tools on your track. This area is reserved for processing tools like equalizers, dynamics, and even some effects processors. These are used in various ways to change the sound of the signal as you mix. Some software mixers have these processors built into them and can be seen on the channel strip. Others leave empty slots on which you can insert plug-ins of your choice in the order in which you choose to place them. Some programs even offer both built in processing and insert options. Insert locations vary from system to system. In Pro Tools, the insert function is at the top on the Channel Strip. As shown in Figure 1.6.

Sends

Sends Pre/Post-Fader- The send function allows you to literally “send” a portion of your signal your signal out to another track called an Auxiliary Bus (or Aux bus), where you can place a reverb or delay. You shouldn’t really use effects like reverb or delay on an insert like would an equalizer or compressor. Doing so will minimize the control you have on how much of the effect you hear in the mix. With the send function, you can use the fader to send (adjust level) whatever amount you the dry signal you would like over into the effect’s (reverb) track. The great thing about using the sends is that you can place them on multiple tracks and send various amounts of each signal the same effect. It is better to send 3 or so sounds into one reverb than to have 3 instances of the same reverb affecting the entire dry signal on each of the tracks. Taking this approach is also, one to step that can be taken towards maximizing your computer’s CPU function.

Pre-Fader- Engaging the Pre-Fader button (magnified above in Figure 1.7) bypasses the actual track or channel fader of the signal. This limits your control over the amount of signal you sent to the effect. Raising the signal’s track fader will make it louder with the effect’s level unchanged. Lowering the signal’s track fader will cause the effect to be heard more.

Post-Fader- mode is when the pre-fader (Pre) button is turned off. Now, your Send signal is being sent to the effect after it flows through the signal’s track fader. In post-fader mode, adjustments made to the track’s volume are also applied the Send function. Most DAWs give you the option of using up to four or more sends per track.

As you can see in Figure 1.7, the Send fader has some functions that are similar to the track. You are given a great deal of flexibility here with more panning knobs, a mute button, solo button (for the track), and even automation mode. Remember you can set up multiple Aux tracks to send your dry (unaffected) signals to. Some effects that are commonly used on Aux tracks in mixing are: Reverb, Delay, Chorus, and Flange. These tracks can also be processed just as the original signals that are being sent to them… BUT hold all ya horses!!! Cuz thatz a whole nuvah topic!

Alright, I think that’s enough for today. Told you it’ll be short. Stay hungry! All you can do is get better and better. Study then application, study and application, trial & error, repetition until you are refined. So, to your homework and go see how these things work in your studio. We are always growing and it’s my pleasure to grow with you. Look out for Part III, we’ll cover some more important information dealing with the mixer! Till then if this has helped you out, please share and comment below. I thank you so much for your time. God Bless!
