Most weapons in the game have +50% bonus damage when channeling. That +50% is what the extra 220% channeling damage affects. While using both your channeled damage bonus will be +160% resulting in you doing 2.6x your normal damage when channeling.

The channeling damage bonus only affects your melee weapon. In the case of Ash none of his abilities give you a melee weapon, so none of them can be channeled, so it will have no affect on him. Excalibur's 4th ability, Exalted Blade, gives him a melee weapon so you can Channel while using it and have the bonus affect the ability.

Also make sure you properly understand Channeling.
