Installation
For proper operation, all directions regarding installation and connection must be
followed.
Mounting
The DC-One should be mounted in a rack-mount enclosure or rack rails. The
unit is 1RU tall by 14” (353mm) deep. Proper clearance for air circulation
around the unit must be provided. Do not block any vent holes on the unit.
For secure mounting and electrical insulation, correct rack screws must be
used – #10-32 screw with plastic / nylon cup washer. All four mounting points
provided by the rack ears must be secured.
Power Connection
The DC-One must be connected to A.C. power only by means of the provided
IEC A.C. cable or by a power cable provided by the dealer / installer to match
the configuration of your country or region. The DC-One must only be
connected to a properly wired, three pin, grounded A.C. outlet. A.C. power
must range from 100 – 240VAC, 50 – 60Hz. The DC-One internal power
supply is an auto-ranging design; no adjustments are necessary to configure
it for proper A.C. power.
Audio Cables
Always use correctly shielded audio cables when connecting to the DC-One.
Balance Input / Output Connections
To minimize induced noise caused by audio cables and to maximize the length
of cables used, balanced connections are strongly advised for both Inputs and
Outputs. The XLR jacks provided on the DC-One are configured as pin 1
ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to
pin 1. XLR – XLR cables or ¼” tip-ring-sleeve – XLR cables can both be used
for balanced connections to the DC-One.
