Enhancer block

Enhancer: in the owner's manual

• Axe-Fx II: 5.9 Enhancer [ENH]
• Axe-Fx II: 16.10 Mono and Stereo

Enhancer: developments

• Axe-Fx II firmware 5: "the new Enhancer uses multi-band 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. Note that it is NOT recommended to use the Enhancer if just using one side of a stereo output as phasing effects may be encountered." More information
• Axe-Fx II firmware 6.01: "Added “Classic” mode to Enhancer block which uses old Haas effect delay-based processing. The Type parameter selects between the new (Modern) and old (Classic) enhancer types."

Enhancer: mono/stereo input and output

• The Enhancer only works when your OUTPUT signal is stereo. Also, don't use it if you only use one channel (left or right) of a stereo signal.
• While a stereo input signal works best, the Enhancer can also "stereoize" an incoming mono signal. Of course, the output signal still has to be stereo.

Enhancer: avoiding phase cancellation

• 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.
• Cliff: "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." source

Enhancer: widening the Panner

• Make the Panner effect appear “fuller” and “wider” (stereo only) by adding the Enhancer.

Enhancer: alternatives

• Cliff: "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." source
