Hooking Up Your Amplifier

Any budding musician should know how to play his/her own instruments. Pianists should know how to fiddle with the piano while guitarists should know how to pluck the strings of a guitar. Any budding musician should also know the other devices that one should have to get the most out of their respective instruments.

There are many accompanying electronic devices that a musician should have as part of their musical arsenal. Of course, each instrument will have devices that are unique to them. For example, a drummer should have a pedal to go with the bass drum. Some of the staple are the equalizers, stereos, cable wires, and the venerable amplifier.

Amplifiers are devices used to make the output of your instrument greater than it’s natural intensity. That is why it is called as an amplifier, it amplifies. Some sounds may be distorted because raw amplification may also amplify unwanted sounds. Equalizers are tasked to edit the sound coming out from the amplifier.

The steps below will talk about the “installation” per se of an amplifier to your chosen instrument. The instrument “guitar” will be used in this case owing to its familiarity for the general public but any instrument will do provided some deviation from the steps to be listed below will be observed.

  • Audio Amplifier (may also be named as Guitar Amplifier for amplifiers specific to guitar use).
  • Surge Protector
  • Guitar (or any kind of instrument that can be connected to an amplifier)
  • Speaker (if amplifier has no built in internal speaker)
  • Equalizer (if amplifier has no built in internal equalizer)
  • Guitar Pedals

  • Most of the power cables in audio amps are detachable. Make sure to never interchange the ends of the cables. You do not  want to insert the end that is supposed to be inserted to the amp to the power outlet.
  • Connect the male side of the power cable (the one with the pointy ends) to the power socket. Make sure that the power socket that you are using is grounded. You do not want to be electrocuted. A socket that is grounded will have three prongs to insert to.

Protip: Get surge protector to defend your audio amplifier from random spikes in your electrical supply. Surge protectors look like extension wires with additional outlets (power strips).

  • Locate the output port on your guitar (or any instrument that is compatible with an audio amplifier). This is located at the front of the head of the guitar, below the strings.
  • Insert one end of the audio cable to the output port of the guitar.
  • Locate the input port of your audio amplifier. This is located at the front of your your amp. Their maybe different input ports as each port will produce a different iteration of the input coming from the guitar. Experiment with these.
  • Insert the other end of the audio cable to the input port of your amp.
