Mounting of the client side
GEC 880 Service Manual

Mounting of the client side
The loudspeaker must be mounted at least 1 m / 40 inches away from the microphone. If possible, the
loudspeaker should not face the microphone directly because this leads to an echo of the operator
voice at the inside station.
1. Mounting version A: Loudspeaker at the top (best for acoustic separation of multiple queues)
2. Mounting version B: Loudspeaker at the side in level of ears (best for single queue situations)
If possible, the microphone should be mounted at the bottom of the counter, in direction to the client.
If this is not possible, the microphone has to be mounted aside in direction to the client. The closer the
microphone is mounted to the clients mouth, the lower the volume required at the operator station.
3. Mounting version A: Microphone mounted in the middle of the counter
4. Mounting version B: Build-in microphone at the side
Microphone client side
The outside microphone should not be mounted nearby the outside loudspeaker and, most notably, it
should not face the sound beam of the speaker(s). The call station will try to suppress audible feedback
at any time and therefore will reduce the outside volume level at situations with high acoustic coupling.
If the outside microphone is installed very near to the outside speaker, maximum outside volume level
will not be possible.
Mouse Microphone Q400
This microphone has a special directional characteristic as shown in the picture. It should be mounted
in such a way, that the speech of the client enters the microphone in direction of the arrows. The
microphone can also be used for outdoor mounting, but it must be protected against rain and moisture.
