What is Millennium?

Requirements and safety regulations

is an industrial sound system that allows to control and distribute intercommunication and public-address system along an installation.

The system layout can be configured either in centralized or decentralized mode, and even mixed as the most versatile way, open to the needs of an installation.

MILLENNIUM is divided into two product ranges:

For 2+ zones: for covering up to 3 zones, designed and planned for small shops and establishments.

For larger-sized facilities, which allow to control from to 27 zones independently, from one to several control points and with a wide range of possibilities.

Installation philosophy

MILLENNIUM architecture is mainly based on one 9-wire bus ( 5 Vdc power supply included), with 4 independent audio-programmes, messages and digital

communication between its units and modules. We can add as many units/modules as desired, connected in parallel and including power supply units distributed

along the installation.

Once this concept is known, the installation can be set up in different ways: centralized or decentralized power supply, or a combination or both.

Centralized installation

In a centralized power distribution, the system management units as well as control and amplifier units are located in the same place to distribute the amplified

sound signal to the speakers in each zone. This type of distribution can be of low or high impedance. Low impedance output will be used when the loudspeakers

are relatively close to the centralization point. Transmitted power is low due to audio signal reduction along the bus-wire length. If opposite, that is remote

loudspeakers, transmitted power is high and then a high impedance installation would be advisable.

A centralized installation has all its amplifiers in the same place, however, control from other places through any 1202 control unit is allowed.

ecentralized installation

A decentralized installation is based on the audio and digital control distribution with low level signals (with less reduction or loss along the wires, which guarantees

a higher quality signal). This type of installation has the advantage of being controlled from any or several control points.

A decentralized installation must have at least one amplifier in each place where we want the sound to reach for the loudspeakers situated there. Their regulation

can be made by using local control units, from any 1202 control console available along the installation as well as from a computer (0801 software). Tha

amplifier/s and loudspeakers in each zone can play the audio programes (music and messages) shared by the whole installation as well as autonomous audio

signals generated in such zone, like microphones or audiovisual equipments on special occasions, to make the most of the electroacoustic resources.

Mixed installation

The mixed installation is the ideal installation as it allows both previous configurations, depending on the needs of the installation.

Is in this situation when MILLENNIUM enables us to combine installation areas with centralized power and other areas with decentralized power distribution.

We only have to install the appropiate MILLENNIUM units/modules, all of them interconnected through a general bus line, usually called "GENERAL LINE" so

that we can control and amplify as needed.

All the MILLENNIUM electrical elements meet the electrical safety regulations and electromagnetic compatibility (CEM ) according to the folowing guidelines:

- 73/23 EEC, modification 93/68 EEC. Low voltage guideline

- 89/366/EEC, modification 92/3 /EEC. EMC guideline

All the sound system installation devices must be connected to the same funcional 230 V~ circuit, and this will be of the exclusive use of such installation,

therefore no other electrical devices that are not part of the installation should be connected.

The mains wires section and acceptable voltage loss, etc, will be established according to the R.E.B.T. 02 criteria (UNE EN 24060).

Mains circuit will go from the electrical general panel through its respective control and protection devices (PIA), as well as overvoltage protection devices.

Regarding the MILLENNIUM sound signal conductors and wires (audio, digital data and power supply) those indicated by the manufacturer or any other that

meets at least the same constructive specifications will be used.

Conductors supplied by EGi 1507LH, 1507.1LH and CML100V to install MILLENNIUM devices comply with intrinsic safety requirements: 750 V isolation, flame-

resistant (UNE EN 50265 and UNE EN 50266), toxic and halogen fumes reduced emission (UNE EN 50267) and/or low fumes emission (UNE EN 50268).

CONTROL CONSOLE

Millennium 2 + 1 message zones

When we say 2 + 1 message zones, what we mean is that the system is able to broadcast messages in three different zones, that can be selected from

the 1201.xx control console.

Two of the zones are centralized, that is, their sound amplifiers are in the 1301.xx audio processor and their control is carried out exclusively from the

1201.xx audio console (only one control console can be present in the system).

The third area is a general line, made of a 5 V power supply line, two music programs and a message channel (5 wires in total), all these provided

from the audio processor. Various control units, amplifiers and local items (microphone preamplifiers, and so on) can be added to this general line, so

locally controlled sound areas can be created, but they work as a single, common zone for messages.

In the next pages we can see several examples of this kind of systems: bar, fashion shop, car dealer, fast-food, restaurant or middle-size company.

ON/OFF push button

One press turns on and the next press turns off

the sound system in that zone.

Volume selector

For raising or lowering the sound level of

the control unit.

Channel selector

This push button enables the user to select the

sound channel ("1" or "2") that will be played in a

zone. Every time that it is pressed, it will change

between the available channels. The selection will

be showed by the light of a red lamp.

NOTE: The adjustment of the message volume

level is done by push-button while a

message is being received. This level is so

recorded for future use.

 There are three IN inputs in the amplifier. The gain of two of them is constant, while the gain of the third one is adjustable. These inputs are added (mixed) internally giving as a result

an input signal to the multiplexer.

If the audio signal reaching a IN or a IN input of this amplifier comes from a MILLENNIUM device, its origin can be a OUT output (such as those present in auxiliary input modules or

in volume regulators for microphone bases) or the + terminal of a control unit. In these cases, the micro-controller of the amplifier detects a direct voltage component (7V ) that is

transmitted together with the audio signal and it reacts to that signal by giving access to it according to the above explained priority order. This 7 V signal is typical of the MILLENNIUM

devices, except for the 1205.

 The order of priority of the amplifier inputs is the following (from higher to lower):

1) udio signals arriving at the 1 terminal block if the digital information at wires 9 and 90 confirms that there is a general call or a private message to this zone-.

2) udio signals arriving to the IN input (see below for connection of non-MILLENNIUM devices).

3) udio signals arriving to the IN inputs.

Whenever an audio signal reaches one of these inputs, all the inputs that have a lower priority level fade down and remain silent as long as the new signal is present.

 Normally non-MILLENNIUM audio sources should be connected to the sound system through their specific pre-amplifiers (1105, 1106 and 1107). If we wanted an audio signal that

does not come from a MILLENNIUM device to directly enter the amplifier, we must connect it to the IN input. In order for this signal to be detected by the IN input, a signal of 15V

must be provided to the terminal block 0, and it will have to remain present as long as we want the signal to keep being broadcast.

 Regarding the amplified output, it can be configured in two different ways: two 10 W outputs over a minimum load of 2 W each or as a single 20 W output over a minimum 4 W load.

The amplifier itself is able to detect how the speakers are connected (if connected only to the 20 W output or if distributed between the two 10 W outputs) and gets automatically self-

configured according to this.

ONLY ONE CONFIGURATION CAN BE USED.
