## What is JAX SR?

The manual is here : https://audio.digitster.com/wp-content/uploads/2024/05/JAX-SR-Phaser-Manual.pdf

The JAX SR Series are AudioUnits (AUv3), which allow to select a frequency range for effect processing.
This one provides a classic phaser modulation effect with optional direct MIDI control assignment to the parameters.

If (especially) modulation effects are applied to the entire frequency range,
this usually will introduce negative side effects. The JAX [SR] Series allow a selective frequency range and dynamic adjustment of the mix easily.

More information can be found on the product website at: https://audio.digitster.com/
Please note, that AudioUnits (AUv3) require a supporting host application to perform.
