=Modes: Classic, Modern, Stereoizer=

'''Classic''' – Old Haas effect delay-based processing. The right channel is delayed by a very small amount to increase the apparent stereo separation between the left and right channels. [http://en.wikipedia.org/wiki/Precedence_effect Wikipedia: Haas effect]

<blockquote>"Classic enhancer mode is just a delay on one side (adjustable from 0 to 20 ms) plus pan & phase adjustment. The non-delayed side will tend to seem louder, just like if you used a delay block to get the same delay time." [http://forum.fractalaudio.com/threads/video-haas-delay-and-how-to-use-it.113156/page-5#post-1422336 source]</blockquote>

'''Modern''' – Multiband techniques for a much more natural effect. Also, the effect is mono-compatible with no phasing problems when summing to mono. The effect both widens stereo signals and “stereoizes” mono signals. Low-cut and High-cut parameters allow control over the region of influence. It is NOT recommended to use the Enhancer if just using one side of a stereo output as phasing effects may be encountered.

<blockquote>"The algorithm is such that when Width is zero there is significant cancellation in the right channel that will cause a shift in the balance."</blockquote>

'''Stereoizer''' – While the Classic and Modern types rely on micro-delays and inversions to create artificial stereo, the new Stereoizer uses multiple high-order filters to create a realistic stereo image.

=Mono or stereo input, stereo output=

While a STEREO INPUT signal works best with the Enhancer, it can also "stereoize" a MONO INPUT signal.

The Enhancer vends out STEREO OUTPUT. Don't use it if you only use one channel (left or right).

=Position of the Enhancer block on the grid=

The Enhancer block should always be placed at the end of the signal routing.

=Tips and tricks=

==Widening the Panner==

Make the Panner effect ([[Tremolo/Panner block]]) effect fuller and wider by adding the Enhancer.

==Alternatives to the Enhancer block==

Use the Delay in the [[Cab block]] to improve stereo imaging. Or the Delay block itself:

<blockquote>"Another way would be to use the Delay block. Set the Mix to 100%, dial in the desired amount of delay and set Balance to full right." [https://forum.fractalaudio.com/threads/30-ms-delay-but-nothing-else.75709/#post-924932 source]</blockquote>

==Avoiding phase cancellation and comb filtering==

When summing a stereo signal to mono, the Enhancer in Classic mode can cause phase cancellation. The Modern Mode is mono-compatible to prevent this.

<blockquote>"Never put the enhancer in parallel or you'll get phasing problems. That's why there is no bypass mode because it should always be in series." [http://forum.fractalaudio.com/axe-fx-ii-discussion/95041-absence-bypass-mode-enhancer-block.html#post1142168 source]</blockquote>

<blockquote>"The Modern Enhancer will survive collapsing to mono but any enhancer should be used judiciously, especially for recordings." [https://forum.fractalaudio.com/posts/1224764/ source]</blockquote>
