Quad Band
The GS-MPIs contain a quad band mobile phone, that will allow the unit to be used in most places of the world, where standard GSM networks are available. If your own mobile phone works, the GS-MPIs will work too. The SIM card fits into a front panel slot and is recessed to avoid accidental removal during operation.

Broadcast Headphone Connection
There is a 6.35mm headphone socket for connecting a pair of headphones or a headset. The units are optimised for an impedance from 200 – 2000 ohms. As the MPIs will often be used in noisy environments, a high output level is available using a variety of broadcast headphones and headsets.

Independent Send & Return Audio Connections
GSM telephone balancing is offered with separate XLR audio connections for the send and return signal. The GS-MPIs offer 100% separation between the send and return paths. The send connection is on a balanced XLR (switchable with a mic imput on the GS-MPI004). The return is on a balanced XLR and contains the return audio (caller) only. There is also independent level control for the send and return audio.

RF Shielding Of Audio Circuits
A carefully designed RF shield insulates the audio circuits from all radio frequency interference. The GS-MPIs own RF does not interfere with its own audio circuits ensuring that typical GSM RF interference is never heard.

Auto Answer
There is a configurable auto-answer, from off to 9 rings.

Memory Dialing
There are 10 memories for instant memory dialling of popular numbers.

Simple LED Status Indication
A red and green LED indicate network and call status.

SMA Aerial Connection
A standard SMA aerial connection is provided for the attached right angle antenna (GS-MPI004) or a separate extension aerial (all rack units)

Two x Four Wire/IFB Circuits
Each circuit can be used independently in four wire mode

Versatile Four Wire Output Options (Programme, GSM, IFB)
1. An external programme input can be switched onto either four wire output
2. The incoming audio from the GSM call can be switched onto either four wire output.
3. One circuit’s four wire input can be switched to its output.

Interrupted Feed Back
When the talk button is pressed the talk audio can either replace the selected output or mix over it (IFB).

LEDs & Loop Outputs
Green LEDs give visual indication of return audio, and a d-type connector on rear with loops is active when talkback 1 or 2 are selected.

Two Position Speak Key
The speak keys are in push to talk mode when pushed down, or latch when pushed up. There is a front panel mic or connection for external mic.

Front Panel Monitoring
There is a front panel speaker, with a 6.35mm headphone socket that mutes the speaker when headphones are connected. Adjustable colume control. Programme, phone, and four wire inputs are all mixed here for monitoring.

Front Panel Mic Input
There is a panel mounted microphone and an XLR socket to connect an external mic if required.
