Glensound HD Voice
The Glensound Broadcasters' Mobile Phone - now with Glensound HD Voice, giving you up to 7 kHz audio bandwidth on a 3G (UMTS) network for the same price as a normal GSM call.The GS-MPI004HD and GS-MPI005HD feature AMR-WB (adaptive multirate wide band), sometimes known as G722.2. This algorithm is more commonly known as HD Voice.This extra bandwidth makes a significant difference in call quality, with improved lower frequency response and much clearer audio.
A Reliable Connection
Glensound HD Voice connects as a 3G (UMTS) GSM call, not a data call, so when connected you will not lose call quality over the duration of a call as often experienced on an IP call. If 3G (UMTS) is not available, the call will connect as a standard 2G GSM call. The GS-MPIHD Range can be set to 2G only mode, a 3G (UMTS) only mode or auto. In auto, a connected 3G (UMTS) call will drop back to 2G if you move outside of a 3G (UMTS) signal area. Please note that it will not switch back if you re-enter a 3G (UMTS) area. Both ends of the connection must be AMR-WB compatible for a HD Voice connection.
Availability of AMR-WB is network specific, and varies from country to country. In the UK, HD Voice is available from the Orange and 3 Networks. Further networks will be offering a HD Voice service very soon.
Extra Bandwidth.....for free!!!
HD Voice is a standard service of the Orange and 3 network. So the GS-MPIHD range will just work on 7kHz, at no extra cost over a regular 2G GSM call. Remember, the network sees this as a GSM call, not a data call.
The GS-MPI005 HD is based on the same technology as the GS-MPI004 HD portable mobile phone. The main difference between the products is that the GS-MPI005 HD is a 1RU 19 inch subrack designed for permanent installation in an outside broadcast truck or studio and the GS-MPI004 HD is a portable unit.
Both ends of the connection must be AMR-WB compatible for a HD Voice connection. That is why we also have the Glensound HD Voice portable Broadcasters' Mobile Phone GS-MPI004 HD. The GS-MPI005 HD is mains powered from a switch mode power supply (100-240V) making it suitable for use of any standard mains power around the world and is perfect for an outside broadcast van power supply.
The GS-MPI005HD can be fitted with 1,2,or 3 separate mobile phones. Each of the phones has its own rear panel balanced audio connections on XLR, it's own aerial connection and it's own front panel controls and SIM card holder.
The GS-MPI005 HD is now available with a desk top remote. This allows the user to store the GS-MPI005 HD in a rack room and operate from the studio. For further information please see GS-MPI005HD/REMD
