# OTTO Rejection Modes
It is recommend you take the ADAPTive Training listed below to understand how ADAPTive systems works:
[https://www.education.eaw.com/training](https://www.education.eaw.com/training)
Below is a basic breakdown of what is happening when changing rejection modes. Please email [Design@eaw.com](mailto:Design@eaw.com)for more details:
This is based on a simple 2-source deep example, it gets much more complicated with more sources.
0% - Sources align at audience surface – No Rejection angle / zone chosen This typically results in end fire, but can be omni when needed.
25% - Rejection angle chosen / End fire with slight gain taper towards rear
50% - Same as 25% with more gain taper towards rear
75% - Rejection method changes to Cardioid (no gain taper)
100% - Cardioid with gain taper
**The gain taper (in 25/50/100) permits more rejection closer to the array, which is commonly needed with subwoofers placed close to the stage location. In this example, it doesn’t provide benefit at the desired location.**
A different array configuration will likely permit better rejection. For example, with a special proprietary filter it has the ability to produce multi-cell deep cardioid arrays, and then it can end fire them together to maintain bandwidth of the rejection. (A group of 3 Otto is the maximum cardioid only rejection.)
