Helpful Terms for when you own an Onkyo Product: Audio Terms

We have decided that there are several terms a person should know when they own one of our products. These terms will come in a series of posts and we will continue to update them. Today we have some audio terms:

Frequency
Audio frequency represents the range of signals that are audible to the human ear. The range of audio frequencies is usually considered to be in the region between 20 and 20,000 hertz.

 Stereo
Audio stereo means sound which is divided into two separate channels. These two channels are played back simultaneously via separate speakers. The effect is to create a fuller sound, and provide the ability to mix certain sounds between channels.

Here are some examples of stereo sound include:

  • Spreading the instruments in a music track from left to right. Often the tom-toms in a drum kit provide great stereo panning, as do some guitar effects.
  • Following the action in a video, e.g. a car speeds across the screen as the audio pans with it.

 Impedance
The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohm resistance and reactance is the impedance.  

LFE
Low Frequency Effects track: The .1 channel of a Dolby Digital, DTS, or SDDS soundtrack. The LFE is strictly low-frequency information (20 to 120 Hz) that’s added to the soundtrack for extra effect.

 AWG gauge wire
Wire gauge is a measurement of how thick or thin a wire is, either in diameter or cross-sectional area. We use 14, 16, and 18. Our home theater system comes with  24 AWG wires.
