Quantum Technology QB4 4-Way Mains Distribution Unit

Quantum’s QBASE distribution blocks are the heart and very basis of the high quality AC supply that your system demands. Deceptively simple in appearance, there is actually far more to them than meets the eye.

The essence of the QBASE concept is a straight-line AC distribution path, combined with a star-earthed topology for connection to a clean ground. By eliminating any form of in-line filtering or active circuitry we maintain the lowest possible AC supply impedance, while a tiny lift in the earth impedance of all but one of the output sockets routes the signal grounds directly to the centre of the star and the clean earth terminal. Clearly identified on the casework, this Primary Earth socket is at the centre of your system’s performance, literally and metaphorically. It defines both the order in which you connect your components and also, their listening priority in your musical enjoyment, allowing you to further optimize the performance of your primary sources.
