Power Supply
The D-7 control surface is powered by a Wheatstone Model PSU-1
rackmount power supply. This unit occupies two 19” wide rack spaces
(total height 3-1/2”). Convection cooled, it requires ample ventilation
space above and below it.
Note the power supply (supplies)
should be mounted in an equipment
rack within fifteen feet of the control
surface (but no closer than 3 feet).
Avoid locating any high gain equip-
ment (such as phono preamps, tape
recorders, etc.) too near the rackmount
supplies, to avoid magnetic interfer-
ence into that equipment.
Once the supply is rackmounted, it
should be connected to the control
surface using the factory supplied
cable. The cable has two different types
of connectors on it: a 5-pin female
connector that connects to the control
surface’s power supply connector, and
an 8-pin male connector that plugs
into the power supply. The control
surface’s two power supply connec-
tors are located at the rear of the con-
trol surface, in the middle of the
meterbridge bottom pan. If you are
using one supply, connect it to one of
