1.4.3 Control
The front panel mounted Six Channel Control Board houses one 15 pin D connector to wire each channel’s remote
control.
Consult the Six Channel Control Board Section of this manual for detailed information on control remote functions and
programming options. Consult the Interface Options and Accessories Section of this manual for detailed information on
the optional interface card applications, wiring and function.
Use the included 15-pin D connector ribbon extenders to plug in the mating D connectors external to the console, as
internal clearance for these connectors is not available inside the console.
1.4.4 Audio Connectors
Millenium Digital consoles may be ordered with 5-pin removable barrier strip connectors or with RJ-45 connectors for
all audio inputs and outputs. Consult the circuit board layout diagrams in the Six-Channel Mixer board and the Output
and Meter Board section of this manual for connector locations and wiring pin-outs.
1.4.5 Wiring Quick Connectors
The 5-pin barrier strip connectors are identical to those that are used in Millenium Analog consoles. When hand wir-
ing 5-pin removable barrier strip connectors, use 22 AWG shielded wire for audio connections. The cable should be
stripped so that the insulation comes close to, but does not enter, the connector. Insert the cable into the connector
and tighten the screw. If desired, first tin the cable to ensure a secure connection.
The RJ-45 connectors conform to the StudioHub+ standards for analog and digital CAT-5 based wiring. When using
the RJ-45 connectors, conform wiring to 568B CAT-5 standards and follow standard IT CAT-5 practices, or utilize pre-
made StudioHub+ wiring and accessories. See http://www.studiohub.com for more information.
StudioHub+ wiring harnesses that bring all input and output connections to convenient connection blocks outside the
console are available from Radio Systems. Consult the factory for literature.
1.4.6 Grounding and Shielding
The installer should elect whether cable shields will terminate (connect) on the equipment side or console side. The
general rule is that shields should not be terminated on both to avoid ground loops.
For shields that do terminate on the console side, on-board jumpers are provided for every input and output, analog
and digital on both the Six-Channel Mixer Board and the Output Boards to allow the programming of the following
ground options for each cable:
1- Unterminated; insert no jumper for the ground to float
2- Chassis Terminate; insert a jumper between the center and “CH” pins to connect the cable ground to the console
chassis ground. This option is recommended for digital (AES-EBU) inputs and most analog signal.
3- Circuit Board Terminate; insert a jumper between the center and “CB” pins to connect the cable ground to the con-
sole circuit board grounds. In the case of the Six-Channel Mixer Board this will connect the cable ground to separate
and isolated console ground buses for both the Analog and digital daughter plug-in cards. This option is recommend-
ed for some Analog signals (AES-EBU), inputs and most analog signals.
1.5 Operation
Millenium digital Consoles have been designed to offer the greatest combination of user flexibility and operating ease.
Foremost, the console should be installed and operated in accordance with station format, personnel habits and engi-
neering principles. However, the following sections suggest some operational possibilities that were considered in the
console design.
1.5.1 Input Assignment
Traditionally, commonly used inputs are assigned to input “A”. This gives the operator quick assurance of proper input
selection.
