Delta System Installation

Step A - Installing the Rack

The first aspect to installing the system is to plan the placement of all the ADA rack equipment,
amps, and source components. Typically, the equipment is best racked starting at the top and
working downward. If you do not have rear access to the equipment, wires can be connected
to components as they are installed permitting the wires to hang while the next component is
added. Also, by lifting components into position rather than resting them on the component
below, you are protecting the face plates and rack handles from knocking together. When
racking from bottom to top, components can be easily dented and scratched.
ADA suggests planning your equipment rack such that sources are followed by the MT-3000
(if used), then the PCT-8 (if used), then the Delta-88s, then the SSD-66/MPA-6s (or other
surround amps), and then all other additional power amplifiers (PF-200's). This format for
racking the equipment will provide a cleaner flow of components and the respective wires and
cables which interconnect all the components.
The ADA Bus™ "short wires" which run from the main frame components to the WH-3000 can
be connected to the component as it is installed but should not be connected to the WH-3000
at this time. You should however, mark the ADA Bus™ "short wires" that terminate on the
WH-3000 with the name of the component they are for. This will make final testing quick and
easy.

Step B - System Mainframe AC Wiring

Running the high voltage cables prior to adding any line level wires gives you the opportunity
to locate the heavier AC cords out of harms way. While wiring the AC is the first recommended
step, the main switching components (such as the Delta-88s, ACC-3000s, ACC-48s, RPS-1s, &
ACC-3s) should be left unplugged from an actual AC outlet at this time. For more information
on the central system's AC wiring see pages 22-37. Please remember that all ADA Bus™
components, whether they are all located in the same place or are located throughout the
complex, all turn off together with the throwing of a specific single components Main Power
Switch. This action permits the entire system to be reset, essential during installation and
system re-booting (power up).
Step C - Sources - Sources to Delta-88, ACC-3000 (or ACC-48), & PCT-8
All main sources will need to connect their AC cords to the ACC-3000 (or ACC-48 if used for
source AC control.). VCRs should typically be plugged directly into an AC outlet. See pages
28-37 regarding AC connection options for the source equipment.
All main sources will need to connect their line-level wires to the Delta-88. See page 17
regarding connecting the sources' line-level outputs to the Delta-88.
The MT-3000 Multi-Tuner should have its three audio line level outputs connected to the Delta-
88's inputs 1, 2, & 3 respectively. Its AC wire is plugged into the ACC-3000's source "1" AC
outlet.
