[DUOX PLUS] Spare part PVT09374 Microphone amplifier CITY

Step-by-step instructions on how to replace the microphone of a CITY DUOX PLUS amplifier.

1. Remove the front of the board with the help of the three side tabs.
   

Use a flat screwdriver to pry it off, being careful not to deform the aluminium.

2. Remove the grille from the chamber and its respective guards. Take care not to damage the plastic tabs and mounting gaskets.

3. To remove the front microphone, carefully pry open the rear casing with a flat screwdriver and prise open the side clips.

4.  We have to disconnect the flat cable from the microphone. To do this, use a thin flat-blade screwdriver to press the black retaining tabs on each side of the microphone. Once opened, the ribbon cable can be released. The microphone can then be removed from the front.

5. Replace the microphone with its spare.

6. To replace the microphone and to facilitate the entry of the ribbon cable, unscrew the three screws holding the plate.

7.Insert the new microphone from the front.

8. From the back, pull the ribbon cable out to its connector and insert it, before closing the black tabs with the screwdriver.

Stretch the flat cable slightly to ensure that it is securely fastened.

9. Make sure that the plate is securely in place, then tighten the three screws previously removed and replace the rear cover.

  10. Fit and ensure that the metal mesh and protective netting are fitted correctly. The metal mesh will fit into place directly on the amplifier grille and the black water-repellent cloth will fit over the rubber in its cavity.

11. Place the plastic protection, matching the cavity in which we have placed the hydrophobic cloth with the microphone and carefully place the lens on top of it.

Note: Always remove the transparent plastic film that protects the lens if it has not already been removed.

12. Fit the grille making sure that it is flush with the lens.

Note: If the grille does not close properly, help yourself by opening the clip with a screwdriver while pressing it into place.

13. We finish by fitting the aluminium front of the amplifier.
