Protection
Control
The following protections are implemented in the UcD700 Power
Supply:
Auxilliary Supply
6.3A/250V fast acting fuses in the secondary power supply.
DC-protection. Switches off the secondary power supply voltages
until
the mains is disconnected.
AC-detect for a pop-free start/stop control. When the mains is
disconnected the UcD700 immediately switches off avoiding
pops.

To avoid ground loops there are two possible grounding settings. The
default setting is for mono applications (Fig 3) and for stereo
applications (two UcD700’s connected to one supply) user must
remove two solder links (bottom of PCB) and make a solder link
(bottom of PCB) like shown in Fig 4.
WARNING! Before changing settings disconnect the amplifier from
the mains and wait at least 5 minutes before soldering. Check the
supply voltages (<45Vdc between Vee and Vcc) with a voltmeter if
possible.

HxR12 option
If your UcD700HG is equipped with HxR12 regulators you need to set jumpers at the bottom of the supply board as shown below:
Fig 5. No HxR12 regulators installed (default setting)
Fig 6. HxR12 regulators installed. Place J33, J34 as shown.
