Energizing
Assuming the D-70 console mainframe is properly placed and
grounded, and its SPS-16 power supply correctly rackmounted and
connected to the console, you may now energize the SPS-16 rackmount
power supply by plugging it into the AC mains. The five LEDs on the
power supply front panel should light up to indicate the presence of
their respective voltages. The console's LED meters will illuminate and
individual module switches will assume factory default settings.
Note: To de-energize the console, unplug the rackmount power
supply’s AC cord from the AC mains. Never de-energize the console
by disconnecting the cable that connects the console and power
supply together.

Audio and Control Wiring
Every input and every output has its own dedicated six- or twelve-
conductor connector (mating plugs supplied). Now in-field wiring
changes are fast and easy, and of course rapid throubleshooting is an
obvious benefit. This system also avoids the conductor pinching and
stray strand shorting that plague screw terminals. Reliability and
maintenance are the keys here.
Connection Procedures
As supplied from the factory, the console requires no logic connec-
tions to function. Therefore an orderly installation begins with the
audio wiring. Note this manual is organized by module type (inputs,
outputs, monitor modules, etc.); each chapter contains detailed wiring
instructions for its module type. Proceed through the manual, chapter
by chapter, until all modules have been wired to suit your particular
installation requirements. Once proper audio operation is verified, go
back to each individual chapter and proceed with control wiring.
Digital Audio Connections
CABLE - All AES/EBU input and output digital audio connections
are balanced and should be made using a high quality digital audio
cable. Be sure to select a digital audio cable with an integral drain wire
of the same wire gauge (AWG) as the twisted pair. Typical AES/EBU
digital audio cable has a very low characteristic capacitance per ft (pF/
ft), and a nominal impedance of 110Ω. High quality digital audio cable
offers better signal transmission performance versus typical analog
audio cable, especially over long cable runs. Check the cable manufac-
tures data sheet to be sure the cable you plan to use will work in your
application.
