R-55e / July 2004
INSTALLATION AND POWER
Power Supply
The R-55e console is powered by an Audioarts Model SPS-100
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 that the power supply should be mounted in an equipment rack
within fteen feet of the console (but no closer than 3 feet). Avoid locat-
ing any high gain equipment (such as phono preamps, tape recorders,
etc.) too near the rackmount supplies, to avoid magnetic interference
into that equipment.
Once the supply is rackmounted, it should be connected to the con-
sole using the factory supplied cable.
The cable has two different types of
connectors on it: an 8-pin female con-
nector that connects to the console’s
power supply connector, and an 8-pin
male connector that plugs into the
rear of the rackmount SPS-100 power
supply. The console’s power supply
connector is located at the rear of the
console, at the right end of the meter-
bridge bottom pan. If you are using
one supply, connect it to the console
connector. If you are using two sup-
plies (failsafe option), connect the long
power supply cable to the center con-
nector of the rackmount failsafe panel.
Then connect one supply with a short
cable to either of the two remaining
connectors on the failsafe panel and
connect the second supply with a short
cable to the last connector.
If failsafe redundant sup-
plies have been ordered,
you will be installing two
units and an additional
rackmount panel.
