Titan-SD PnP Upgrades For OEM Atlas, Proto 2000, BLI and Other Factory Installed Sound
Here is an opportunity for the over 300,000 purchasers of factory equipped QSI sound locomotives made by Atlas, Broadway Ltd, Proto 2000 and Intermountain to upgrade to the new advanced “TITAN” DC/DCC sound decoders. See TITAN feature list (external link).
Most of the original factory installed sound diesel locomotives used the same special format circuit board SD (small diesel), that was screw mounted to the chassis. For simple wiring there were 6 convenient mating plugs for all connections, see wiring diagram below. This facilitates and simplifies the circuit board replacements. Even modelers with limited skills will be able to do the circuit board substitution.
Examples of the QSI SD (small diesel) decoder installed in factory locomotives.
The ordering process and/or determining what specific sound files you need is straightforward. The Item ID includes the prefix Titan-SD followed by the sound file number that was used on the factory equipped locomotives. See the list below:
The Atlas SD24 P/N (ho111) designation is:
The Proto 2000 GP20 (ho130) designation is:
The numbers (hoXXX) designate the specific software ID for the original factory locomotives. The sound file number can also be determined by a read back of the decoder’s information by both DC and DCC users. See this and this document (both external PDF files).
Please note that the sound file numbers on the list below are for reference and correlation only. QSI Solutions will convert the numbers to the new Titan Sound Set IDs.
The Titan-SD DC/DCC replacement sound and power decoders will be available in late July or in early August. MSRP: $119.95.
