The constant growth of the technological innovations in the field of the communications, makes a suitable solution also for the radio reportages.
RBB Radio Broadcast Box proposed by ELMAN, occupies little space and it becomes, once open, a practical and versatile posting to work, ideal for all the RadioNetworks that use the radio reporter without the help of technical personnel.

The system is realized in a rigid suitcase in polipropilene, provided of integrated telescoping cart, with trailer handle for drawing and lifting function.

The codec/mixer allows to realize radioreportages or interviews through a ISDN line (Connected to the port of the Network Terminal Plus with RJ45 interface ), so to effect a full duplex connection with the headquarter, using CCITT G722 protocol for the coding.

It is a complete system to transmit the news, contained in a suitcase that represents the top of the portable systems for the news.

Easy use, any complicated setup, compatible codec/mixer with the most common codec for ISDN lines on the market and, a simple and intuitive GSM Hybrid.

Any your specific request can be arranged, projected and manufactured, together with the ELMAN's engineering team .

Transmission with Codec for ISDN lines

We give some information about the digital lines. The ISDN, offers to Radios Networks the possibility to spread high quality modulation mono or stereo simply composing a telephone number. A line ISDN is composed by two channels (said channels B) with a bit rate of 64 Kbps (anymore a channel of signaling (denominated D) with an rate of 16 Kbps). A basic channel “B” ISDN has a bit rate of 64 Kbit/s and using configurations that go from a single channel (half ISDN line) up to 6 syncronized channels (three ISDN lines to 384 Kbit/s), can be had bandwidths from 7,5 KHz mono (G722) up to 22,5 KHz stereo or dual channels assuming a compression of 4:1 (MUSICAM). Compression ratios more exasperated can be obtained, on a single ISDN line, at 128 Kbps (ISO-MPEG1 Layer 3).

The compression coding incorporating any type of actual algorithm, introduces a delay in the elaboration that can go from few milliseconds, in some codec, to about ten milliseconds in others.

This suitcase has been projected to meet all the requests of the radioreporters offering, in a single container, everything is necessary to transmit with the last technologies.

The audio codec offers a perfect quality audio , from the 20kHz of bandwidth of the protocol ISO MPEG Layer II to the 7 kHz of the CCITT G722, to arrive with an analogical telephone line to the 3,4 kHz of the CCITT G711.

The user (in the example in figure) arrives in a Soccer Stadium, opens the suitcase and through the cable he connects the power supply, then using the cable RJ45 in endowment, it connects the codec to the Network Terminal plus.

notice that it is possible to have a optional TV/monitor with remote control that accepts any video signal: PAL, XGA, NTSC(only like monitor).

We advise to put ON the limiter because it has really excellent performances. In the case in which a ISDN line is not available but there is only a normal analogical telephone line, the connection can be effected however, setting the codec in the protocol CCITT G711 (telephone bandwidth: 3 Khz) and connecting it to the port RJ11.

In the unfortunate case in which you don't work neither the line ISDN neither the telephone line, no fear because in the suitcase is contained a hybrid (powered by battery or by power supply) for connect it with a cellular phone endowed with headphone/microphone. In the case of live transmission, in which the return was disturbed or unintelligible, in the suitcase is also lodged a digital radio receiver ready to the use like return in headphone.
