Behringer manufactures a number of mixers for live music applications. It produces a number of inexpensive mixers as well as high-end mixers meant for professional use. The more-expensive models generally have more audio channels and built-in effects. Low-end models have as few as four inputs and no built-in effects at all, while more-expensive mixers can have 20 or more inputs and dozens of effects. Regardless of which Behringer mixer you choose, all operate using the same basic principles.
Instructions
1. Turn the main volume knob on the mixer and individual input channels all the way down to zero. This will prevent pops or audio surges that can damage your speakers during setup.
2. Connect your speakers to the main outputs on the mixer.
3. Plug instruments and microphones into open input channels on the Behringer mixer. Depending on the instrument's output connection, you will need either a 1/4-inch instrument cable or a standard XLR cable in order to make the connection.
4. Get levels. Have the musicians play their instruments one at a time and get appropriate levels by turning the gain knob up on the corresponding input channel. Turn the gain knob higher until the level meter is close to but does not exceed the clipping threshold. You will know the signal is clipping when the level meter turns red and the clip indicator lights.
5. Add equalization (EQ). Add EQ to each input channel by turning the lo, mid, and high EQ knobs up or down. This allows you to bring out the character of each instrument by reducing or increasing certain frequencies. For instance, you may want to turn the mid up on a guitar to make it cut through a mix better, or you may turn up the lo EQ on the bass guitar in order to create a bigger bass sound.
6. Add effects. If your mixer has built-in effects, use the send knobs to add effects like reverb or delay to individual input channels. If your mixer does not have effects built in, you can connect an external effects processor using the FX send output.
7. Mix the instruments together. Turn the volume faders up or down on the individual input channels until you have achieved a good instrument mix.
8. Turn up the overall volume. Turn up the main volume knob to increase the overall volume of the mix until you have reached the desired listening volume for the venue.
