Isol8 PowerLine Ultra 4 Way
Isol8 four-way mains block for audio systems, with one dedicated amplifier socket and three filtered sockets for sources.
Description
The PowerLine Ultra 4 Way is a mains block designed to power a hi-fi audio system. It offers four sockets allocated according to function: one dedicated to a power amplifier, the other three intended for the source components of a system.
The socket marked Direct Connection incorporates a high-current shunt filter, designed to meet the demands of power-hungry loads such as power amplifiers. The other three sockets benefit from one or more stages of the Transmodal filter developed by Isol-8, a filtering technology applied specifically to the system's source components.
This arrangement allows the power supply for the amplifier, which draws significant current, to be separated from that of the sources, which are more sensitive to mains disturbances, each benefiting from treatment suited to its use.
This mains block is intended for users with a hi-fi system built around a separate power amplifier and several source components, seeking to organise and filter the power supply across their entire system.

What to check before buying used
Check that all four mains sockets show no play or signs of heat damage, particularly on the Direct Connection socket subject to the amplifier's current draw. Inspect the original mains cable and the IEC connector at the rear of the unit, as wear here can compromise shielding. Test each stage of the Transmodal filter by listening through the source sockets in turn to detect any background noise or reduced filtering effectiveness.
