Glensound GS-MPI004 Broadcasters Mobile Phone

The GS-MPI004 has been designed to finally solve once and for all the problems of using mobile phones for audio broadcast purposes. 

Our engineers have excelled themselves with this design to make your life as a broadcaster easy, so if you want a reporter to do a quick interview in the high street, or need to use the phone network for 4 wire communications, or want a reliable back up circuit for a codec, or would like to connect a mixer to a phone or indeed for hundreds of other uses then the GS-MPI004 is for you.

To make broadcasting from anywhere in the World easy the GS-MPI004 has a QUAD BAND GSM interface allowing connectivity with most of the Worlds mobile phone networks and a SIM card holder accessible via the front panel to allow different network SIMs or roaming SIM cards to be quickly and easily fitted or changed.

Obviously a portable mobile phone like the GS-MPI004 is battery powered, to prevent it not being charged when you need to use it in a hurry it does not have internal rechargeable batteries but instead is powered from standard readily available AA cells.

What about quality? Because the GS-MPI004 has a digital GSM module the audio quality is the best you will ever get from a phone network. With the audio being in the digital domain separation between the go and return channels is 100% which far outperforms even the very best standard wired telephone hybrids. Our chief engineer has spent a long time perfecting the compressor/ limiter circuit and the audio input circuits to the phone network for you, the result means that you only need to roughly set the input level and the high quality electronics will make sure that your signal is sent without distortion to the studio. As you would expect from Glensound mechanically it is housed in a robust custom made aluminium case that is lightweight but extremely strong, so you don't need to worry if you drop it or bash it, it will keep working.
