HOW TO OPERATE A SOUND SYSTEM

Common live sound sources are microphones (for vocals, speech, acoustic instruments, and instrument amplifiers), electronic instruments, DJ decks, and audio players.

In addition to combining multiple sources while adjusting their relative levels, a mixer provides the necessary preamplification for microphone and line level sources, and can be used to apply equalization, dynamics processing, and/or effects.

The line-level output from the mixer is fed to one or more amplifiers that provide the power needed to drive the system's speakers. Some mixers and speakers have built-in power amplification, reducing the number of separate components required and enhancing portability.

Speakers convert the electronic signal from the system's power amplifier(s) into audible sound. A dazzling variety of speakers and speaker systems are available, so unless you're planning on acquiring a preconfigured package you will need to carefully choose models that suit the specific application.

      We will introduce how a mixer works, this is the most important role in the "Signal Flow" of the PA system. We will use the MG16XU 16 channel mixer as an example.

      * No sound comes out if any of [2] [8] [9] is down.

      1. INPUT SOUND

      From microphones to musical instruments, playback devices and more.

      2. ADJUST SOUND VOLUME (GAIN)

      Before you can begin to mix sound, you have to adjust the input gain for each channel first.

      3. COMPRESS SOUND (COMPRESSOR)

      By narrowing the dynamic range (the difference in volume between loud and soft) you can fine tune both your vocals and instruments to get the best sound for your venue.

      4. ADJUST SOUND QUALITY (EQ)

      You can adjust the sound quality by using the 3-band equalizer for High, Mid and Low frequencies. By boosting High frequencies, you can add clarity and presence. Boosting Mid frequencies can help make vocals easier understand, and by adding Low frequency you build “Bottom End” giving the mix more power.

      5. ADJUST SOUND POSITIONING (PAN)

      The PAN knob adjusts the channel to the left, right or center of the mix, this is especially useful when using stereo signals from a playback device, synthesizer or electric piano.

      6. MUTE A CHANNEL (ON/OFF SWITCH)

      When the channel is not being used, you can mute the channel output.

      7. SEND TO STEREO OUT (ST SWITCH)

      By engaging this button, you can send the channel output directly to the main stereo out on the mixer.

      8. CONTROL CHANNEL OUTPUT GAIN (FADER)

      The fader is used to increase or decrease the output volume for that channel. In order to keep your gain to 0db, make sure to adjust the channel input gain (2) first.

      9. ADJUST MAIN OUTPUT VOLUME (STEREO OUT)

      This adjusts the final mix signal up or down to the system amplifier in a passive speaker system, or directly to the speakers in an active speaker system.

      10. MAIN MIX LEVEL METER

      You can monitor the overall system gain with the level meter. When the Peak light comes on, you are overdriving the system and could cause damage to amplifiers and speakers.

      11. OUTPUT STERO OUT SOUND

      These are the Left and Right main output signal that are sent to the power amp or powered speakers.
