Sound for the DD40AX?

Hello, anybody knows what decoder & sound will be fine for the new HO Bachmann DD40AX? Thanks.

Hi,look at the QSI-website-they have in their new QSI-revolution-series a sound for the DD40AX[tup]Steffen

The problem with the DD40X is that it has 2 prime movers, and thus, no one has the proper sound set.

The Soundtraxx Tsunami AT-1000 EMD 645 Turbo charged would work as well as the QSI…but it wont sound exactly like the DD40x.

Personally I would install two GP40 sound units, one for each prime mover in the DD40. The exact engine sound you need is a 645e3a with 16 cylinders.

I have considered adding sound to my DD40AX with a GP40 decoder. What I have been told is that some sound decoders have a setting called reverb (an echo) which makes it sound like there are two prime movers running.

Reverb is NOT an echo.

Reverb will not make it sound like 2 prime movers. The ONLY way to do this properly, would be to use 2 LokSound decoders and pitch-shift them (not every motor sounds the same). If you install 2 of the same motor decoders from Soundtraxx or QSI, you will just get a doubling of the same sound.

Either way it is an expensive sound install.
