COMMITTEE ROOM EQUIPMENT
Type GSWL-SR20    Mic Amps

GENERAL
This is a 2U subrack and can contain up to 16 identical mic amps type GSP52. In addition each subrack must always contain a mix amp type GSP51. In any system up to 16 of these subracks may be used. They can accommodate up to 255 mic amps. In a system it is possible to fit a further two modules namely modules GSP53A or GSP53B. These are designed especially to provide inputs from Audio Visual and Video Conferencing systems if required. If these modules are fitted the total number of possible mic amps is reduced to 253.

CONTROL
Each mic amp is intelligent and needs to communicate with the main controller GSWL-SR22. It is therefore necessary to provide each with a unique address. This is achieved by giving each subrack an address by means of a DIP switch and each mic amp by means of its physical position. The DIP switch is located on the mother board and can be accessed by removing the mic amp in the sixteenth position.
A further two DIP switches are provided to set the addresses for the Audio Visual and Video Conference modules when fitted. These are accessed by removing the corresponding module.
