Radio Systems Millenium-A Console
1.1
Console Placement
Because neither ventilation, or rear access is required, the console may be mounted on any sturdy surface. Opening
the lid provides access to all electronics, internal controls and wiring points.
After placing the console, open the lid and mark the cable access slots on the chassis bottom on the table surface.
Remove the console and cut the slots with a saber saw. The console may then be permanently mounted with two #10
sheet metal screws inserted through the two holes provided in the front of the chassis' bottom.
1.2
Opening the Console
A "T"-shaped lifter is provided by the factory to open the console.
This lifter can be inserted in any fader slot, angled and used to raise the lid. Once the lid is opened, the two hinges are
pulled forward to lock the lid open.
To close the lid, push the hinges in to release the locks, while holding the lid up with the "T" lifter, and gently lower the
console.
The external lifter discourages unauthorized access to console electronics.

Power Supply
1.3.1
Installation
All console operating voltages are provided by the external power supply which connects to the console via a multi
conductor cable. A ten foot length is provided as standard equipment. Longer lengths, up to 20 feet, are available from
the factory.
To install the cable, remove the top cover of the power supply and insert the end of the cable with the large solder lug
through the rectangular cut out in the power supply back panel. Plug the connector into the circuit board and secure the
solder lug to the ground stud provided on the inside rear panel. After replacing the top cover, the supply may be hung
from the key-hold slots in the cover, placed on the shelf or the floor, or rack mounted with the optional rack adapter front
panel.
To connect the console end of the power supply cable, pass the other end of the cable (with the smaller ground lug)
through the rectangular hole on the center right-hand-side of the console base. Screw the ground lug under the mount-
ing screw on the right front hand side of the Output Board. Plug the 10 position connector into J24 and the 4 position
connector into J26(Ouput Board v.2: Plug the 10 position connector into J6 and the 4 position connector into J8).Take
extreme care to plug these connectors in with the correct orientation - locking tab to loacking tab (with cables existing
towards the right hand side) as it is possible to plug them in backwards.
A grounding stud is provided on the rear of the power supply. Console grounds reach a common point at the power sup-
ply. To minimize RFI and potential ground loop problems, the console should only be connected to station ground at this
one ground stud.
In intense RF environments, or if you experience any RFI problems, consult RFI suppression in the Troubleshooting and
Theory of Operation Section for detailed information.
1.3.2
Configuration
The power supply houses a switch-mode module and an interface and indicator board. This provides 15 volts for audio
circuitry and 7.5 for control circuits.
Front panel LED's show the status of both 15 volt modules and the 7.5 voltages derived from the first module. Fuse
holders are front panel mounted housing a 2 amp fuse for the first module and a one amp fuse for the second.
