A piece of Promethean Technology that controls resonant fields. It is often used to suppress or control Aug abilities that rely on field manipulation. Telekinesis, ferrokinesis, pyrokinesis, and more are all vulnerable to Resonance Regulators.

Some Resonance Regulators have been known to short out if a strong enough Aug creates a powerful enough field that causes feedback. Resonance Regulators are only effective within a certain range which varries on the power of the device.

Shielding from abilities such as telepathy can be achieved through ABW Filters.
