Internal Power Supply and the PSU32 Redundant back-up supply
The MSX 32 uses an internal toroidal transformer based power to get the maximum benefit from the ultra low noise design of the splitter circuitry.

However, for “critical” applications where systems must keep operating, we recommend including the PSU 32 Backup/Redundant power supply unit. Individual +V, -V and 48VDC rail LED indicators show when the PSU 32 redundant power supply unit is connected to the MSX 32.

An illuminated power switch on the front panel provides visual confirmation of AC power connection to the unit.
Six XLR type 5 pin connectors on the rear panel enable 1 x PSU32 to provide automatically switched backup power to up to six MSX 32 units.
