The Qx2 unit contains a pair of QRT field generators in a specially designed, mechanically inert casework. Fed by a standard 15A IEC input, a standard US 3-pring AC outlet. It does not limit peak voltage swing, or alter the power supply impedance, and is capable of passing sufficient current to supply an entire system.
The Qx2 can be used individually, between the wall socket and your power strip, or within the system itself to feed an individual component. It is particularly effective used in this role in conjunction with a Qx4 feeding the system as a whole.
