Analog (DC) Operation
The LokSound Select Dual-Mode decoder allows your Atlas Gold Series locomotive to be used on DC as well as on DCC layouts.
Please note that the Atlas Quantum Engineer will NOT operate an Atlas Gold Series locomotive equipped with a LokSound Select decoder on an analog (DC) layout. However, the sound and lighting functions of the LokSound Select decoder in the Atlas Gold Series C424/425 locomotive can be controlled by an easy-to-use basic DCC system
Also note that on a DC-powered layout, a DCC and sound equipped locomotive (such as the Atlas Gold Series C424/425) CANNOT be consisted with another locomotive that does not also have both DCC and sound. (This statement does NOT apply to DCC-equipped locomotives operating on a DCC layout.)
Over 20 sound effects are available, including engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes and more.
There are 16 user-selectable horns, 2 user-selectable bells, and 2 user-selectable synchronized brake squeals.
Manual and Automatic Notching modes with the ability to change modes ?on the fly? are provided for true realism.
