Digitrax SDYH588ST Series 8 DCC Dual "Stereo" Speaker High Output Sound Decoder - 11-pin JST to Hardwire

Digitrax decoders ship to us with a preloaded sound scheme but are reprogrammable like other decoder options that we offer.  The Digitrax Sound Depot offers several additional sound file options for unique prototypes for modelers to choose from.  You can also find hundreds of Custom Sound Files by John McMasters on the AnPRR@groups.io site.  These are proprietary sound files created by the author and are offered free of charge with all rights reserved.

Digitrax offers the Digitrax PR4 USB to LocoNet Interface with SoundFX Decoder Programmer that can be used in combination with the ESU 53900 LokTester DCC Decoder Test Station to load sound files, update decoder firmware, program CV values, test and troubleshoot decoders or installations, and even to create your own custom sound files.  Please note, you must use the Digitrax PR4 USB to LocoNet Interface with SoundFX Decoder Programmer to load sound files or update firmware on the Digitrax Sound Decoders.  You can program CV's on any Digitrax decoder in Service or P.O.M. mode using your Digitrax Zephyr or Evolution Command Station, any NMRA-compliant programming device or software such as JMRI/Decoder Pro.

SBS4DCC will preload any sound file from the Digitrax Sound Depot or Custom Sound Files by John McMasters with the initial purchase of an Digitrax Sound Decoder for no additional charge upon request.  SBS4DCC will pre-load other third party OEM and non-OEM files in most circumstances but a processing fee may apply.  Please CONTACT US to discuss your specific project or needs.

There are two ways to request that SBS4DCC pre-load a sound file when you purchase a Digitrax decoder from us. 

The preferred way is to enter the Sound File Name (having the format "ALCO Century 420", etc.) in the space above labeled "REQUEST A PRELOADED SOUND FILE (NUMBER OR NAME):".  You can enter a prototype model or prime mover type if you are unsure but using the file name guarantees you will get the exact file you want.

The second way is enter the same information noted above in the comments field at checkout but those notes will print on the shipping label so best to use the space provided.

As always, CONTACT US with questions.
