    Monitor Speakers – are full-ranged speaker system for the band
    members especially in concert or gig to keep track of the
    sound or audio Feedback from musical instruments they are
    playing and voices from singers in order to maintain the musical
    beat during the performance.


    These speaker systems are trapezoidal or wedge-shaped, usually smaller
    in size and are placed near the performers on the entire section of the
    stage.

    Headphone – is a miniature sound monitoring device used by sound
    operators to maintain a harmonious production of sounds
    during group performances. “In ear” headphones or ear buds
    are commonly used by band members such as drummers,
    keyboardists and singers.

    How to Install Your Loudspeakers, Monitors, Audio
    Mixer and Feedback Suppressor to Your Amplifier

What is a loudspeaker?

    A loudspeaker (also known as driver or speaker) is an
    electromagnetic device used to convert electrical or
    audiosignals into sound.

    The main set of speakers  or speaker system is used to
    deliver controlled and amplified sounds to the audience.

Sound energy such as your voice and sounds produced by musical
instruments are converted into electrical or audio signals by microphones
and electric guitar pick-ups. These signals are processed and amplified by
audio mixers and amplifiers. On the other hand these processed and
controlled electrical or audio signals are converted back to a good quality
sound by loudspeakers for the audiences’ good listening pleasure.

Audio Feedback

Audio feedback is what happens when a sound loop exists between an
audio input signals such as from a microphone or guitar pickup and an
audio output signals like that coming from a loudspeaker.

    This is also known as Larsen Effect, named after a   
    Danish scientist who discovered this feedback loop.
    A "high pitched squealing sound" is produced when
    a microphone or electric guitar pickup signal is
    reproduced  on an amplifier which is then picked up
    again by the same microphone or electric guitar
    pickup. Then the same signal is amplified and
    reproduced again.

Audio feedback are circumvented by placing the main speakers far
away from the microphones and having the monitor speakers facing
the opposite direction from the microphones.

    Professional setups use an electronic device
    which suppresses or prevents the picking up
    of signals in the audio feedback loop thus the
    name, "Feedback Destroyer Pro" a product
    from Behringer.

Audio signals from your audio mixer are sent to the Left and Right Input
of the feedback suppressor through the Pre-fader AUX Sends 1 and 2.

From the Feedback suppressor, audio signals are sent to the Amplifier
through OUTPUT left and right. The Monitor Speakers are then connected
to the left and right audio output of the Amplifier.

The Main Speakers are also connected to the Amplifier through the
OUTPUT Left and Right.

You can now do the gig with your 5-man Rock Band . . .
    Speaker System
    A speaker system is composed of the following:
  • Sound-insulated box enclosure or Cabinet
  • Electronic filter component – audio
    crossover or dividing network
  • Drivers or speakers
    Types of drivers or speakers:
  • Subwoofers (very low frequencies)
  • Woofers (low frequencies)
  • Mid-range (middle frequencies)
  • Tweeters (high frequencies)
  • Supertweeters (very high frequencies)

    Audio crossover or Dividing Network
    Crossover Network splits audio signals into separate frequency bands
    (high and low frequencies) to produce clear and undistorted sounds.

                                              
                                            Active crossover network – the low/high
                                             frequency signals are split by the crossover
                                             network and amplified individually before
    the individual signals are sent to the  
     corresponding high/low frequency speakers
     in a speaker system.

    Active x-over Network       
                                            Passive Crossover Network – the amplified
    low/high frequency signals are split and sent
     directly to the corresponding low/high
     frequency speakers.

                                             Some crossover networks have the
    capability  to split low range/mid range/high
     range  frequencies to produce clearer and
    undistorted sounds.
    Passive x-over Network



    Components of a driver or speaker:
  • Voice coil
  • Magnet
  • Diaphram
  • Frame or Structure



    How much power your loudspeaker can handle?

    Power Rating of Drivers or speakers
  • Program Power Rating – is the optimum power range of  your
    amplifier in terms of Watts that won’t cause damage or that
    matches the load capacity of your loudspeakers. Anything
    more than the recommended power range of your amplifier or
    anything less will ruin your speaker system.
  • RMS (Root Mean Square) – is the thermal power limit that your
    loudspeaker can withstand. This is expressed in terms of dB.

    *The power output of your amplifier must also match with the
    nominal impedance in terms of Ohms (4 or 8 Ohms).

     Caution:
    Bear in mind that you can not just install your loudspeakers
    to your audio mixers and amplifiers without matching the
    recommended power ratings.
