When moving off-axis of a directional microphone the level of the audio will drop because the whole point of a directional mic is to accentuate what’s directly in front of the mic, reduce what’s not.

Refers to an audio source that is not directly in front of a transducer, especially a microphone. This results in off-axis coloration; a distortion or change in the frequency response of the reproduced audio signal.

On-axis means that the speaker (any speaker) is facing/aimed at the intended listener. Off-axis means that the speaker (any speaker) is NOT facing/aimed at the intended listener.

That is off-axis speaker response. At some point, as you move out of line (off-axis) with the tweeter, the speaker will start to sound different. In general, however, a “good” off-axis response refers to a speaker sounding the same as on-axis for a wide range (usually up to 30 degrees).

Depends on the speaker, specifically the high frequency dispersion angle, but in general, yes. Most speakers have a 30 degree full bandwidth dispersion angle (+/- 15 degrees from directly on axis). If you can cover all your HT seats with that and not toe in, then you don’t have to.

When you toe-in a loudspeaker you are altering: The tonal balance of the direct sound – more toe-in equals more high frequency energy since tweeters becoming directional at higher frequencies. The level of the lateral side wall reflection. The relationship between the direct and early reflected sounds.

The definition of an axis is a real or imaginary line on which something rotates, or a straight line around which things are evenly arranged. An example of axis is an imaginary line running through the earth on which the earth rotates. A main line of motion, development, etc.

An axis is an invisible line around which an object rotates, or spins. The points where an axis intersects with an object’s surface are the object’s North and South Poles. Each planet in our solar system rotates on its axis.

Off-axis means angling the mic a little to the side. This can make the high end roll off a little and make things sound a little smoother.

Off-axis optical system. Jump to navigation Jump to search. An off-axis optical system is an optical system in which the optical axis of the aperture is not coincident with the mechanical center of the aperture.

Refers to an audio source that is not directly in front of a transducer, especially a microphone. This results in off-axis coloration; a distortion or change in the frequency response of the reproduced audio signal.

In photolithography, off-axis illumination is an optical system setup in which the incoming light strikes the photomask at an oblique angle rather than perpendicularly to it, that is to say, the incident light is not parallel to the axis of the optical system.

Off-Axis. Refers to an audio source that is not directly in front of a transducer, especially a microphone. This results in off-axis coloration; a distortion or change in the frequency response of the reproduced audio signal. Often this coloration is put to good use. For example, many engineers intentionally set up mics on guitar amps
