GLENSOUND EXPEDITION MOBILE PHONE 4G/3G/2G, HD, portable

Glensound HD Voice Broadcasters' Mobile Phones make it possible to use the 3G UMTS network as an audio link, with a bandwidth of up to 7kHz, for broadcast applications. The increased bandwidth is more suitable for live reporting applications as well as higher-quality IFB and talk back applications. Should a 3G network not be available, they will also act as a normal quad-band 2G GSM phone. They have balanced, line-level connections, with XLR connectors, for ease of interfacing to broadcast mixers, recorders, or computers. The portable version also has a dynamic microphone input. The phones connect as a voice call, so will have the same quality of service as a normal mobile phone call. The call quality will remain constant over the duration of the call regardless of the number of other mobile phones being used in the area. As a result, they are particularly suitable for reporting in highly-congested mobile phone areas such as football matches or concert venues.

The phones connect to 3G mobile phone services, as well as 2G. When connected to a 3G service offering 'HD voice', they provide a bandwidth of approximately 7kHz; a substantial increase in audio quality compared to a 2G or PSTN phone. However, in order to take advantage of the increased bandwidth, the call must be received by another 3G phone using 'HD voice'. Glensound 3G phones can be used to connect to PSTN or 2G phones, but in these cases the bandwidth increase is lost.

In 3G UMTS mode, the standard version offers 900MHz, 1900MHz, and 2100MHz bands. An optional 3G UMTS version is available for compatibility in other parts of the world offering 850MHz, 1900MHz, and 2100MHz. In 2G GSM mode, they connect to any quad-band network at 850MHz, 900MHz, 1800MHz, and 1900MHz for international compatibility. Audio bandwidth is 50Hz to 7kHz in 3G mode or 300Hz to 3.4kHz in 2G. Audio circuits are shielded from radio frequency interference, so the self generated RF will not interfere with the audio.

A large LED flashes and a sounder, which can be switched off, rings to indicate incoming calls; there is a variable auto answer. A nine-memory phone-book offers access to stored numbers and a redial button can be used to call the last-called number. A 6.35mm A/B gauge headphone socket is available for monitoring. The balanced, analogue, (XLR) audio inputs and outputs have separate controls for level adjustment. The aerial is connected by a standard SMA socket; different aerials may be connected. Power is supplied by 4x AA batteries in portable units, or, optionally, an external DC source. Rack mounting models mostly have an internal switch-mode supply, some are available as alternative models which accept DC power.

GS-MPI005HD - Rack mounting - Modular

This has a single GS-MPI005HD Broadcaster's Mobile Phone fitted in a 1U frame to fit a 19 inch rack. Two further GS-MPI005/EP phones may be fitted into the unused spaces covered by blank panels. The front panel of the GS-MPI005/EP has the same facilities as the GS-MPI004HD, except a jack socket is added for headphone monitoring. It has the dialling keypad with nine-number phone book and the slot for a SIM card. Two large square buttons are used to dial or hang-up a call, each with LED status indicators. Configurable auto answer may be selected. There are separate level controls for the input and output levels, +/- 10dB; a volume control sets the level for the A/B gauge 6.35mm jack socket for headphones of 200 - 2000 ohms impedance. An LED indicates that the compressor/limiter is active to aid setting the input level. A tri-colour LED indicates the signal strength. Advanced configuration allows setting of echo canceller, noise suppressor, peak compressor, and headphone audible alert.

The rear panel has an XLR connector for the balanced, analogue, audio input at a line-level of 0dBu. There is also an XLR for the analogue, balanced, output which has a maximum level of +13dBu. The aerial connector is an SMA type. There are two remote connection options: a B type USB for PC control, and a RJ45 for a CAT5 link to the GS-MPI005HD/REMD. An IEC inlet accepts power: 100V - 240V AC. RF power output: 2W. Dimensions: 482 x 44 x 258 (w x h x d) mm, 1U rack mounting. Weight: 1.74kg, as supplied, with one phone.

Glensound 2G phones connect to a mobile network and offer an audio bandwidth of approximately 3kHz. They can make a call to a another mobile phone or a PSTN phone number. With PSTN, the audio contribution can be accepted by an existing telephone hybrid, coupler or a phone-in system. Alternatively a Glensound portable or rack-mounting mobile phone can be used to receive the call, either at fixed premises, or on location, say in a outside broadcast vehicle.

The 2G models are suitable for areas where 3G 'HD voice' services are simply not available, or it is not possible to have a 3G 'HD voice' phone at both ends of the connection, or that the enhanced audio quality is not required, perhaps for a cue feed.

Up to two additional GS-MPI005/EP modules can be added to a GS-MPI005 in the field. Details and specifications of the phone is as the phone fitted in the standard GS-MPI005.

GS-MPIFW - Rack mounting - With 2x 4-wire IFB comms circuits

The phone section on the right of the front panel is similar to the phone module in the GS-MPI005, with the overload light absent. The front panel contains the dialling keypad with ten-number phone book and the slot for a SIM card. Two large square buttons are used to dial or hang-up a call, each with LED status indicators. Configurable auto answer may be selected. There are separate level controls for the input and output levels, +/- 10dB. A volume knob controls the level of headphone monitoring of the mobile phone call, connected through an A/B gauge, 6.35mm, jack socket to headphones with 200 - 2000 ohms impedance.

On the left, for use with the 'four-wire' 'IFB' circuits, there is a speaker and a 6.35mm headphone socket, with level control, for use with headphones of 200 - 2000 ohms impedance. Inserting a headphone jack mutes the loudspeaker. These are used to monitor a mix of incoming audio from the two four-wire talkback inputs. The programme input may also be mixed into these, using a rotary control. An LED indicates when programme audio is present. A panel-mounted microphone is adjacent to an XLR connection for an optional external dynamic microphone. The choice of the panel or external microphone is selected by a toggle switch. After internal gain adjustment, the selected microphone feeds a limiter and then to the talkback switching, feeding the four-wire outputs.

Two identical sections in the middle of the panel are used to feed cue audio back to the two four-wire outputs. This 'cue' may be either the external programme input, or the incoming audio from the mobile phone, or the incoming feed from the four-wire line, which can be fed straight back (foldback) to the outgoing feed. Each section has a rotary control to set the mix level of the incoming four-wire feed in the loudspeaker and headphones; an LED indicates when audio is present. A three-position toggle switch sets the source of the cue audio, programme, phone or foldback. A two position toggle turns the 'cue' on and off. A paddle switch has three positions; it locks in the upper one, sending the microphone signal continuously to the four-wire output. The lower position is momentary, performing the same function when held down. In the centre, any cue selected is fed to the output with no talkback. A further toggle switch selects whether the cue is 'cut' when the talkback key is operated, or the cue and talkback signals are mixed to feed the output.

The rear panel has a section for the phone, with the balanced line-level analogue audio connections, input at 0dBu, output with a maximum level of +13dBu, both using XLR connectors. The aerial connector is an SMA type. Again on the rear panel the programme input (0dBu, balanced) is a 3-pin female XLR. Two pairs of one female and one male XLR provide the two, balanced, four-wire inputs (0dBu) and outputs (+13dBu maximum) respectively. There is also a 9-pin D-sub connector for connection of indicators or external switching when talkback 1 and 2 are on. An IEC inlet takes 100 - 240V AC. RF power output: 2W. Dimensions: 486 x 208 x 44 (w x d x h)mm; 1U rack mounting. Weight: 2kg.

Included accessories: T-bar aerial, 2.5m cable.
Optional accessories: Mag-mount aerial, 3m cable.
