The module allows the connection of up to four music sources (Tuner, CD, Tape...) with -10dB nominal output level. A switch on the front panel selects which of the four sources should be passed to a previously chosen BGM bus (chosen with an internal jumper setting).
The system admits up to 4 modules for BGM input assignable to 4 different musical programmes. There can be only one MLT4 or MLT1 module assigned to a certain musical programme. It features tone control and a volume control associated to a bi-colored LED indicator which facilitates an optimal level adjustment (It should light green, not red).

The module features stereo inputs through RCA connectors. Input nr.4 also includes a balanced monophonic input through a ¼" Jack connector.

We will be able to have different sources from sound for a same single channel of music with only one module of entrance of sound sources.

 

Module to connect a standard microphone in order to send messages to prefixed zones independently of the main console, using the same sound system. Possibility to connect remotely the microphone and ON switch. The spoken message can respect or not respect (working as BGA mode) the priority system. It has a tone control designed specially to improve the intelligibility in deficient acoustic installations. The level control is associated with a double colour LED to improve the level adjustment. Internally configurable input sensibility by JUMPERS to be adapted to different microphones (dynamic, gooseneck, wireless, etc...).

Installations where spoken messages need to be broadcast to one or more zones on a regular basis ( No need to address the message each time it's broadcast). If set as BGA, the module can be used to send long announcements without taking over the system.

 

Allows the connection of standard microphones or audio sources and sends messages to pre-set zones.
In order to address a message with the microphone or audio source connected to this module, the front "ON" pushbutton should be pressed or the "ON REMOTE" switch should be activated remotely. The module addresses the message as long as the "ON" switch is active. 
However, the special Voice Over function broadcasts the message without the need for manually activating the "ON" or "ON REMOTE" switch. The Voice Over function, which can be enabled by setting an internal jumper, activates the module automatically when an incoming signal is detected, be it from a microphone or from an audio source. The module automatically deactivates itself after 3 seconds without any signal input.
A specially designed tone control is built in to enhance voice intelligibility in problematic set-ups.
The volume control is associated with to a bi-colored LED indicator, which helps when adjusting the optimal audio level (it should light green, not red).

The message can be replayed once or cyclically. The spoken message can respect or not respect (working as BGA mode) the priority system. The source for message saving can be an external microphone or a console or an external sound source (CD, cassette, etc). The level control is associated with a double colour LED to improve the level adjustment.

Easy to use module for the playback of recorded commercial ads and customized alarm or evacuation calls.

 

Module used to generate two acoustic alarm/alert signals in the selected zones respecting the priority system. Each alarm activates independently with an external signal (START), with the possibility of remote activation. The duration of the acoustic alarm/alert can be programmed in three ways.

The alarm/alert signals of the modules section 1 can respect the priority system or not (working as BGA mode). Internally you can select three alarm types and two acoustic alert types for each section of the module.

Totally adaptable to any kind of alarm or external clock featuring a trigger output signal.

 

Module assigned to diffuse any spoken message from any PABX (telephone switching board) extension with optional chime. The module takes one extension of the PABX. The message can have a maximum time duration (AUTO HANG, between 6 and 30 secs) to avoid blocking the system by mistake. In case of tones PABX, it is possible to stop the message before its ending just dialling a preselected number and then the module will stop it. It has a tone control specially to improve the intelligibility in deficient acoustical installations. The level control is associated with a double colour LED to improve the level adjustment.

This module is able to broadcast messages to one or several zones from a telephone extension branch.

 

Module to connect background music to PABX (telephone switching board) for waiting times. It permits to send any of the 4 BGM programs to the PABX. The signal output is isolated by transformer. There is a control to adjust the optimum sound level.

You can use one of the music channels in the setup (MLT1 module) to provide music to the PABX, using it for waiting calls.

 

100 volts amplifier module without to need a matching transformer. Opposite to the most part of 100 volt line amplifiers, this module doesn't need matching transformer. This means a higher sound quality due a transformer increases clipping and frequency distortion at low frequencies. This means less weight as well. There is not floating output due to it doesn't use a bridge structure. The system permits to select up to five BGM programs (4 BGM plus no-music) and to assign them to 12 zones. The BGM is attenuated or completely attenuated when a message or alarm is being sent. This module has an anticlip and DC OUT protection circuit as well. The amplifier incorporates a 50 Hz subsonic filter to avoid the possible saturation of the speaker matching transformers when replaying very low frequencies. Possibility of listening or not to BGA messages. Available at 30/60/120W.

You will have to use one of these amplifiers depending on the total power required to drive the installed wall-mounted speakers, enclosures, horns, etc.

 

Module including the controls of the signals to adapt the BGM, the messages and the alarms (including the priorities hierarchy) structure to an external amplifier. The system permits to select up to five BGM programs (4 BGM plus no-music) and to assign them to 12 zones. The BGM is attenuated or completely attenuated when a message or alarm is being sent. The amplifier incorporates a 50 Hz subsonic filter to avoid the possible saturation of the speaker matching transformers when replaying very low frequencies. Possibility of listening or not to BGA messages.

For zones where the required power ifs far more than 120 W or a low impedance amplifier is needed.

 

Module to power external relays. This module activates a relay that disables the individual attenuators of each room in case of receiving a message. This module can control up to 100 relays (current consumption 20 mA each relay) and distribute them to four different zones.

Whenever you are installing attenuators, you will need to install one of these modules for 4 attenuator-equipped zones.

As you might already know, each MR24 module is able to drive up to 100 relays spread over 4 different zones. In the above example, you would install two MR24, one for zones 1, 2 and 3 and another one for zones 4 and 5.

 

Stabilised voltage power supply for up to 9 signal modules and amplifiers with total added power up to 240W (for instance 8 x MP30 or 4 x MP60 or 2 x MP120...).

One of these power supplies is always included with the main chassis. Depending on the modules to install, you will need one or another.

The 240 W chassis will not only supply the amplifiers but also the rest of modules you may wish to install on the same chassis.

 

Module with digital programmable clock and two independent circuits. Digital clock featuring 8 start and 8 stop commands on each channel. These triggers can be programmed inside different groups of weekdays. The module is powered by an internal battery which automatically recharges through the power supply on the enviro chassis, whenever it is switched on. The battery has a proven autonomy of 3 months.

This digital clock allows you to automatically trigger the various signal modules in an Enviro system.

 

Module for external BGM selection and general volume control. The module has two sections for controlling two different amplification modules. This module consists of two sections. Each of these sections can be connected to a amplification module (MP30/MP60/MP120) or external amplifier control module (MCA1). From this module you can externally select the desired BGM for the zones assigned in the amplification module. This module also offers a general volume control for each section and is always accessible for instant control. The volume control will act as a general gain for the output signal of the amplifier module to which it is connected.

This module lets you change the background music of the different zones from its front panel. A single module can be used to select the background music for two different amplifiers. Features two general volume controls assigned to the two amplifiers connected to the module.

 

Complementary power supply for a chassis with an installed power supply. The MPS240C is a power supply that provides the necessary stabilized voltages for signal and power amplifier module types. The total load capacity is 240 W. Mechanically, this complementary power supply consists of two separate parts: The first one includes the mains transformer while the second one comprises the printed circuit board and the other power supply components. When mounting this power supply into an enviro chassis, you are actually installing two independent enviro systems inside the same chassis. Therefore, both power supplies must be interconnected via the external expansions found on the rear panel.

These power supplies do not include the enviro chassis, therefore they must be installed next to an already existent power supply with chassis (MPS240).

This 240 W complementary power supply not only provides the necessary currents for the connected amplifiers (up to 240 W total output power), but also feeds the signal modules placed next to it.

Let us imagine a small gym with following zones: Reception + Locker rooms. Workout room (approx. 100m2). Room 1: Relaxation courses (approx. 50m2). Room 2: Stretching courses (approx. 50m2). The requirements in this gym are first, to have the same ambient music in all zones and second, to be able to locate the gym personnel and attendants from the reception. The two rooms where courses are being held need calm music; i.e. the music volume should not be very high. It has therefore been decided to install ceiling-mounted speakers. In these two rooms, it should be possible to select (from within the rooms) either the gym's ambient music or another music dedicated to that room. That means that several music input modules (MLT1) must be used and that both rooms will feature a programme selector (SL4). The following plant drawing represents the distribution of the rooms and the ceiling-mounted speakers:

The functions in this installation require an enviro system with a 240 W chassis, where the different amplifier modules, console link module and music input modules would be inserted. The installation diagram would be following: The aforementioned requirements result in the following equipment list:

 

Let's suppose you hold a furniture decoration store containing two separate areas: One zone for conventional furniture decoration (Zone 1, approximately 320 m²) and another one for ethnically themed decoration (Zone 2, approximately 80 m²). In the ethnical section you wish to have music according to the style, while in the other section you desire another kind of music. Consequently your setup will have to consider two distinct zones and two distinct music styles, one for each zone. Suppose you also need to broadcast messages from the cash desk located in zone 1. These messages will be addressed to the entire store, with no zone distinction. For that reason you can install a single microphone module instead of a console to send messages. You don't need a console because all messages are always sent to the same zones. As you can see in the following plan, 12 speaker boxes are installed in an 100 V-Line , 8 in zone 1 and 4 in zone 2. Each of these speakers is rated 15 W, but each zone has different power requirements:

According to this speaker arrangement, both zones will have an equally distributed direct sound field between 90 and 93 dB. Product list according to the requirements specified above:

 

Let's imagine an office building belonging to one company. There are 4 floors, the ground floor holds a reception and an exhibition room, while the other three contain the organizations offices. The aim of the PA system is to provide ambient music to all floors and to be able to locate employees from a PABX in the reception. For that purpose, the building will be divided into 4 zones, each representing one floor. Each office floor (suppose equal arrangement) includes different departments and office rooms. It is evident that the listening preferences for the background music differs from one person to another, but for practical reasons it's impossible to install an individual attenuator and loudspeaker for each employee. Therefore you will have to group certain loudspeakers in one room and install a single attenuator for that group. In the office rooms however, you may wish to install single speakers with dedicated attenuators. The following plan shows a possible arrangement of ceiling-mounted speakers and attenuators:

To fulfil the specified requirements, you would install an ENVIRO system with 4 60W amplifiers for the 4 zones, an external relay supply module (MR24) and a 4-Zone console together with its connection module to the chassis, which will feature a 240W power supply. Whenever you are installing attenuators, you will need to include one of these external supply modules. This module consists of 4 sections and can be used for 4 different attenuator-equipped zones, one section per zone. When doing a broadcast to a attenuator equipped zone, the module will activate the corresponding section thus supplying current to the attenuators internal relays. The message will be heard although the volume is set to zero. For the wiring of this setup you must consider that two cable pairs must be extended from the rack to the attenuators: From the MP60 output and from the corresponding MR24 section. The speakers will then be connected to the respective attenuator output. The arrangement of the setup is as follows: Product list according to the requirements specified above:

 

Let's imagine a large room that is subdivided into three smaller rooms with moving walls. These sub-rooms are normally used for holding separate conferences or exposition, so that each section has to include a dedicated line for microphone and music signals. But the possibility to merge two or even three sub-rooms must not be excluded, meaning that all three sub-rooms should share the same line. The installation should also allow calling for persons in any of the three sub-rooms from a console placed at the building's reception. Consequently, the sub-rooms will correspond to following zones:

As not much sound pressure is necessary (the sub-rooms will be quite calm), it has been decided to install ceiling-mounted speakers. To control the volume of these speakers from the sub-rooms themselves, each of them has a volume attenuator installed. To mix all signals involved in a sub-room together, one SAM502 mixer is being used for each sub-room. Microphones and other sound sources are fed into them, and the outputs of the three mixers are respectively connected to three MLT1 (sound source input module) of the Enviro system. The figure on next page shows how the ceiling-mounted speakers are distributed through the sub-rooms:

As the requirements stated, sub-rooms can be merged into larger rooms. To fulfil this need, a MSB2 module (external BGM selection module) has to be installed for every two amplifiers. Following points list some of the operating possibilities:

The functions in this installation require an enviro system with a 240 W chassis, where the different amplifier modules, music input modules, console link module, relay power supply module and BGM selection modules would be inserted. The installation diagram would be following: The aforementioned requirements result in the following equipment list:

 

In small hospitals or surgeries doctors usually need to call their patients to attend them. Thanks to a simple ENVIRO setup, doctors will be able to announce the name of the next patient from their own desk, through their telephone. The message will be heard in the waiting room. As you can see in the following plan, the 14 ceiling-mounted speakers are installed so that they all belong to a single zone, with the same background music. The surgery rooms don't need speakers. The separation between speakers should be approximately 4 or 5 metres. The power requirements though, are different for each area: The reception and the waiting room will need 3W per speaker and the corridor 1.5 to 0.75 W (maximum installed power ratings). All this speakers can be driven with a single power amplifier module. The system which is able to broadcast messages via the telephone line is easy to install and easy to use. You only need one free extension branch on your PABX (preferable digital PABX, if it is an analogue one the system will also work, but the hang-up procedure would be somehow different, see ENVIRO manual). The installed MTT1 should be connected to this extension branch . The doctors just have to dial the branch number and speak out the message. If doctor A wants to send a message but doctor B is doing so at the same time, doctor A will hear a busy tone, meaning that the system is occupied. Doctor A will have to wait until doctor B finishes his call. Messages can also be broadcast from the reception using the same MTT1 module and the telephone installed there. Plan of the surgery: Product list according to the requirements specified above:
