But now we have to bring that effect back into our mix, almost like itвЂ™s a new signal - and in fact it really is a new signal. Once the signal is sent to the effect processor, digital technology does its thing, creating a reverb or delay effect. (To learn more about aux sends, check out this Tools of the Trade blog posting.) The use of rotary knobs allows you to apply the effect (in differing amounts) to more than one channel. The aux sends on more advanced Yamaha models like the MG16XU use rotary knobs, as shown below in that particular mixer, you turn up the AUX4/FX knob in order to send the signal to the effect. The original unprocessed sound is called the вЂњdryвЂќ signal, while the added reverb or delay effect is called the вЂњwetвЂќ signal.ДЇor example, the effect send on a Yamaha MG06X mixer consists of a simple on/off pushbutton that sends the signal to the effect. These sends are usually called aux sends (short for вЂњauxiliaryвЂќ), although they are also sometimes called Effect sends).

Return to SenderДЄdding reverb or delay to a sound (or group of sounds) is almost always accomplished with something called a send, which takes some of the audio from a channel (or channels) and routes it either to a built-in effect or to an output on the mixer, where it can be patched to an external effect. Now letвЂ™s describe how exactly they can be added to your mix and give you some tips on how best to use them in live sound.

In Part 1 of this article, we talked about the basics of reverb and delay - two important effects that add spaciousness to a sound.
