With this MPC500 Power Controller you can protect your home audio investment because inconsistency in power quality can cause costly damage. The MPC500 delivers full mode AC power line surge protection, such as from a lightning strike, as well as protecting low voltage devices against secondary surges and spikes that can occur after the initial event. Keep your home audio safe. AC power line protection uses three TPMOV’s (thermally protected metal-oxide varistors) which are far safer than traditional MOV’s that provide Line to Neutral, Line to Ground and Neutral to Ground protection. For secondary surge events, the MPC500 provides protection for ethernet, coaxial, and other low voltage devices via Gas Discharge Tubes (GDT), Positive Temperature Coefficient (PTC) thermistors and Transient Voltage Suppression (TVS) components. Of course the MPC500 features also the timeless McIntosh black glass front panel, illuminated logo, control knobs, and aluminum end caps. Compatible with all power systems. The appropriate receptacles are available in each individual country to ensure compatibility with local power systems. Control of each receptacle can be configured via the rear panel Power Control ports or through the setup menus on the front panel. The MPC500 also has an electromagnetic interference (EMI) filtering of the AC line and over/under voltage protection. This will switch off the rear receptacles to keep connected devices safe from trying to operate at undesired voltage levels. The front panel display can list input voltage, the amount of current being drawn through the receptacles, or total (apparent) power.
