Eela Audio EA816 GSM hybrid:
GENERAL REMARKS:
The EA816 is a stationary telephone hybrid for the GSM network. It is an industrial quality quad band
GSM module with AMR-WB codec and the facilities for use as a broadcast hybrid.
For use in areas without cabled telephone connections.
To make use of the new HD-voice (Advanced Multirate - Wideband) facilities more and more mobile
telephone companies are offering. The audio bandwidth is extended from 50 Hz to 7 kHz for a crystal
clear sound, ideal for the radio reporter in combination with the S25 Reportophone.
Depending on your network provider and system used it can be a huge money saver. In a lot of
countries a call from mobile to mobile is much cheaper than from mobile to fixed or visa versa.
Facilities for broadcast applications include remote control on GPIO. For special applications the unit
has an auto answer and auto disconnect mode as well as a switch that can be operated from the dial
pad of a remote telephone. An external switch can also be connected to the unit to dial the number
stored in pos 1 of the memory.
HD-VOICE:
HD Voice based on AMR-WB (Adaptive Multi Rate) Wideband technology provides enhanced audio
quality to 7 kHz bandwidth on mobile networks. This system is being rapidly implemented by various
telecom providers. A large number of phones including Nokia, Samsung, HTC and LG have the codec
installed. Also our S25 Reportophone will do fine. With improved sound quality (and low cost) within a
reliable network, this system is ideal for reporting purposes. More information about availability in
your country can be found on the website of the Global mobile Suppliers Association (GSA)
www.gsacom.com.
The system is automatically activated when both devices are equipped with such a codec. The EA816
offers the solution on the studio side: An industrial quality GSM module in a half 19 "housing for fixed
installation. The EA816 will interface to the studio mixing desk as a regular hybrid including balanced
audio input and output and opto isolated GPIO for control.
The unit is housed a 1 U half 19" rack unit. Rackmount kits are available as an option.
Please note:
The SIM card used should not have a PIN code other than pin code 0000!
This is done to avoid several problems involved with PIN codes, amongst others to make the unit
restart automatically after a power shut off.
