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.
