The MSR-602 II is the system power supply providing all the necessary DC voltages for the MSR-604 II. It utilises a custom designed low field toroidal transformer and separate mumetal screen to reduce the possibility of mains field coupling into the electronic circuitry of the MSR-604 II. The HEADROOM LED meter and high quality headphone amplifier give the operator absolute confidence in signal integrity during setting up, and provide an indispensable aid to trouble shooting and fault detection. The signal wiring involved is contained with the power wiring in a multicore cable for simple interconnection between units. In addition, it also carries the main system ground switch which has
important considerations within a large system for both safety and noise.
