Rear Panel Features
All MH10/MH10f rear-panel features and functions are described in this
section. Individual differences between the MH10 and MH10f will be
called out as needed.
AC Power
Pro64 modules use switching power supplies that can operate at 100-
240V and from 50-60Hz, meaning that they can be used with most of
the world’s AC power systems by simply changing the line cord. The
MH10/MH10f is equipped with a standard grounded IEC power inlet
(with fuse) which can accept the interchangeable IEC power cord.
Access the fuse by pressing on the spring-loaded hatch beneath the
AC power inlet.
Fuse
The fuse holder is spring-loaded and has space for two fuses, one main
and one spare (optional). Press the fuse holder cover to access the fuse.
When checking or replacing a fuse, always power off the Pro64 unit and
remove the line cord from the AC power source.
Always replace the fuse with one of the same rating as that being
changed.
Backup DC Power - MH10f
For applications where a backup power source is required, the MH10f
is equipped with a backup DC power inlet using a locking 4-pin XLR
jack. A DC power supply capable of outputting 24VDC ±5% at 1 amp is
required. In the locking XLR plug, connect pin 1 to ground and pin 4 to
the 24VDC supply.
