Listing description

System Overview

The 4000 Digital Series is a Digital Communications System using a central switching matrix for routing
calls between outstations connected in a star format.
The digital central switching matrix uses a microprocessor for control and configuration purposes. A
Digital Matrix Card, allowing multiple routes to be made simultaneously achieves all switching and
routing. Analogue audio, GPI inputs and outputs, data interfaces and an advanced software package are
also provided as part the 4000 system.
A range of Digital Control Panels are available providing a suitable user interface for making and
receiving calls over the system. These panels contain push buttons configured to operate specific routes
or activate control functions. The push button actions are sent as digital data using a serial link to the
central matrix for interpretation by the microprocessor and information is returned to the control panel by
the same method. Audio is sent and received digitally, multiplexed with the data via a single co-axial
cable. Audio and data can also be connected via standard twisted pair wiring or CAT5.
The standard control panels provide the basic facilities of Direct Access Keys (DAKs) which allow singlebutton operation for frequent calls, a Reply key for responding to unscheduled calls and where
applicable, a dial display for making infrequent calls.
A call is initiated on a control panel by pressing one of the assigned DAKs or, on panels equipped with
an electronic dial-pad, by dialling a number and pressing the call button. This activates crosspoints,
located in the Matrix, which make the audio route (or routes) to the desired destination(s). Routing can
be one-way (e.g. talk only) or two-way (talk and listen simultaneously) and several callers can speak to
the same destination at the same time due to the mixing capability of the matrix.
The crosspoints in the matrix are activated or de-activated according to configuration rules held in the
system's Matrix map (stored in the microprocessor's memory). The system map for the 4000 Digital
Series residing on a Personal Computer is downloaded into the Matrix from the 'Configuration and
Master Assignment Programming System integrated' (CMAPSi) and controls every aspect of 4000
Digital Series operation. The Matrix sends part of the system map out to each control panel,
programming the actions available on each DAK of each panel. This includes any special function that
may also be assigned to a particular pushbutton in addition to initiating the normal dual routing.
Each DAK may be centrally configured and assigned to a destination, source or both at system set-up.
On some panels, DAKs that are not assigned at system set-up can be assigned, by local programming
of the pushbuttons in Soft mode, to allow different routing options. Local assignments may not be
retained if the system is reset, although they are held in non-volatile memory at the panel and thus will
be retained after power down.
Destinations and sources can be other panels, beltpacks, 2-wire or 4-wire circuits, either individually or
in groups. The destinations and sources could also be in another talkback system. Connection to other

4000 Digital Series systems can also be achieved by use of Ethernet, providing an integrated private
intercom network. Up to eight 4000 Digital Series systems can be connected using this facility.
A Conference facility is also available, configured via CMAPSi, which allows people to converse in a
conference mode. This is similar in operation to the Conference Ring (Party Line) facilities available in
older conventional systems. Users can be allowed access to any conference (up to 64 conferences are
allowed) either to listen only or to talk and listen

UAE’s only one-stop shop for used and refurbished broadcasting equipment. Home to the only inventory of used, refurbished and demo equipment in the Middle East, we buy and sell high-quality used broadcast and AV equipment to radio and TV customers primarily in the Gulf as well as other parts of the word.

We source our equipment from premier broadcasters in the region and employ an efficient team of engineers to refurbish and service the gear we have acquired before selling them. All used broadcast equipment comes with a three-month warranty.

We have successfully provided integrated solutions and equipment to end users in U.AE, Egypt, India, Jordan, Pakistan, Afghanistan, the Philippines and Turkey.

Having established a firm foothold in the Middle East and Asia, BSBroadcast is constantly looking to extend its portfolio of equipment and solutions through partnerships with leading European and American used equipment dealers

The Ceo, who has worked in MENA region to build broadcast facilities from scratch, established BS Broadcast in 2016. On this journey, the CEO identified a need among customers for revamped and restored equipment at lower costs. Additionally, he has been active in the Middle East and South Asian broadcasting industry since 1999 and has developed a vast network of contacts that came with requirements for used equipment.

In essence, the company was born out of these demands and presently serves customers worldwide. Having a base in the UAE has helped facilitate easy shipment across the globe.

Our inventory includes an extensive range of 3G/HD/SD equipment including playout servers, satellite antennae and terminals, RF modulators, frequency converters, multiplexers, HPA, SPG, waveform monitors, up-converters, routers and switchers, and more from the world’s leading manufacturers.

Whether rotating out your existing equipment, or clearing out your storage area, bsbroadcast.com can assist you in securing maximum value for your investments. Should you want a quote for your used systems cameras, broadcast lenses, mixers or SR decks, please contact our trade sales team.
