line after one ring signal. A black/white list of

numbers is under design.

stored in the internal GSM memory. It means the

GSM Hybrid can work standalone in the field.

and PC is completely redesigned and based on

the proven AIRLITE communication protocols.

Description

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.

With the GSM GPI jack wired correctly to a mixing consoles GPO a call can be taken on the mixing console.

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.

A great complementary product for our GSM Hybrid is the Audio Adapter SMARTRIG that we can offer as an "in the Field" product for only € 49,95
Together with a dynamic or condenser Mike, headphones and a smart-phone (Android or Apple) running a
recording app on it could be your complete mobile reporter set for a minimum of investment.

Live reporting to the Studio in Voice-HD directly to our GSM Hybrid is now possible (depends on your GSM and provider).
