GSM-STUDIO HYBRID

TIP!

If you need higher audio quality than your regular digital or analog studio hybrids give you, use this GSM Hybrid as your main studio number.

Anyone who then calls you (and has a HD Voice subscription) will talk to you with an extended bandwidth up to 7kHz., this results in clear natural sounding audio.

It makes your studio sound a lot more professional and increases intelligibility quite substantial. Just give it a try.

Dear Sirs,  For several weeks, we are using your D & R GSM Hybrid.  This is a very good device and it has a good sound. Best regards, Andrzej

New features ( May 22, 2018)

- Auto Connect: The application ‘GSM Hybrid Control’ automatically connects

to the device on start-up or re-connect if USB connection is lost.

- Auto Answer: The application now picks up the line after one ring signal. A

black/white list of numbers is under design.

- All settings done in the application are now stored in the internal GSM

memory. It means the GSM Hybrid works independently from a running

application once programmed and can be used in the field without a PC.

- A fast Factory Reset is possible by pushing the CONNECT button 15

seconds.

- The communication between the GSM Hybrid and PC is completely

redesigned and based on the proven AIRLITE communication protocols.

NOTE: In case existing users want to update the GSM Hybrid application

software, they also have top download the latest firmware to get all the

extra’s at https://www.d-r.nl/wiki/dokuwiki/doku.php?id=software:start

With the D&R GSM Hybrid you can add a simple and effective wireless interface that your reporters can call.

With features like HD voice, Echo canceling, digital EQ and application control over USB on your PC it is a nice tool to expand the communication

possibilities of your studio with your reporters in the field.

The GSM Hybrid has its own number reporters directly can dial, the call can be taken on the mixing console due to built in GPIO’s.

The electronics are housed in a sturdy metal 9.5” rack mount case with antenna’s on the front side for optimum receiver conditions.

An external 12 volt power supply adapter is part of the delivery. Software features are in and output metering and level control, phone dialing, number recognition and GSM signal strength indication.

The Alert feature is implemented to let a reporter in the field ‘wake-up’ a DJ behind the desk to start an interview. Assumed is that a connection is already there and the DJ is doing some other work in the studio while the reporter waits for the moment to start the interview. On that moment the reporter only has to press the ‘0’ on his phone to Alert the DJ. In the main window of the GSM Hybrid Control application the background starts blinking red for 2 seconds.
Also the GPO output alternates with this Alert signal. Doing so, the DJ knows the reporter is ready for the interview and he can mix in the reporter to the show.

If the GPI is wired a call can be picked up on the mixing console when the GPI is connected to the GSM's GPI jack connector.

If you want to install one GSM-Hybrid in a 19" rack you can use our mounting kit and 1x 9.5" blind panel. See below.

If you want to install two GSM Hybrids you need only the mounting kit, see picture above

Mounting kit € 17,--
