How to Monitor Audio in Ceiling Speakers

Ceiling speakers allow businesses and homes to funnel audio from a single source into a room or rooms. This can be beneficial when providing your customers with mood music or if you wish to have the freedom to go room to room in your house while still listening to music. In order to ensure that your audio levels are suitable for your environment, it is helpful to have a VU (Volume Units) meter to monitor the cables. These meters use LEDs or a needle to indicate the level of the sound being played.

Instructions

    • 1

      Locate the audio source for your speaker system.

    • 2

      Unplug the RCA cables from behind your sound system. These should be the cables coming from the "Audio Output" jacks.

    • 3

      Plug the cables that you just unplugged into the "Audio Output" jacks behind your VU meter.

    • 4

      Plug your additional RCA cable into the the "Line Input" port on your VU meter. There should be two ports, and two cables.

    • 5

      Plug the other end of your RCA cable into the "Audio Output" jacks on your audio source.

    • 6

      Plug your VU meter into a power source.

    • 7

      Turn on your VU meter.

    • 8

      Turn on your audio source and press "Play." You should see your audio levels as pulsations. If you have an LED VU meter, you will see the lights pulsing to the right going from green, to yellow to red.

      If you have an analog VU meter with a needle, you will see the needle pulsing to the right. It will pulse further to the right depending on your volume level.
