Dapol Class 142 'Pacer' DCC Sound Installation

Mistakes may damage your locomotive, controller or other accessories. Use a multimeter to make absolutely sure you have completely isolated the motor from the track before testing. Always use the Programming Track for testing. Our guides are provided for reference only, and you proceed entirely at your own risk. Unsure about something - try our DCC Conversion Service instead.

The speaker and sound decoder are installed in the dummy car. For the optimal experience, we recommend also installing a decoder in the motorized car that is syncronized with the sound decoder.

Step 1 - Remove body

Remove the body by turning the unit upside down and unclipping the front where the plastic tapers inwards.

Step 2 - Modify Decoder PCB

Undo the two screws holding the decoder PCB in place. Turn the PCB upside down and solder two brown wires to the solder pads marked 'Speaker +' (S+) and 'Speaker -' (S-).

Step 3 - Fit Speaker

Fit the speaker into the centre void where the motor would ordinarily be. Secure it using glue or black tack, then solder the brown wires to the speaker terminals.

Step 4 - Fit Decoder

Fit your sound decoder, replace the body and the conversion is complete.
