LokSound V5 DCC Sound Chip

Designed specifically for the accurascale Class 37  locomotive with ‘Original’  Engine Configuration, this decoder works seamlessly with the onboard lighting, PowerPack stay-alive system and dual speaker configuration to reproduce the characteristic sound and function of the locomotive at work.

This chip is suitable for all 37/0, 37/1, 37/2 37/3 Variations as they ran before the engines were refurbished. For chips suitable for all other Class 37, see here

Common Features:

  • The LokSound 5 decoder works for analogue DC and AC (!) layouts.The LokSound 5 decoder can reproduce up to 10 channels simultaneously. Each channel offers up to 16 Bit / 31250 kHz and thus we have finally achieved hi-fi sound quality on your layout. For all practical purposes one cannot detect any difference to the original. A class D audio power amplifier with up to 3W output power feeds the speakers with a permitted impedance of 4 – 32 Ohms. The huge 128 MBit sound memory assures sufficient storage capacity.The volume of all individual sound fragments may be adjusted separately. The outstandingly flexible sound engine without a rigid flow chart facilitates a prototypical simulation of all conceivable rail vehicles. Three separately adjustable braking functions and two alternative load scenarios provide you with maximum control of your vehicles.We are quite aware that you want your locomotives to be as realistic as possible. Therefore we have packed many function outputs into it.  Subject to the type of interface every LokSound 5 has at least 10 amplified outputs. The decoders with PluX22 or 21MTC interface have an additional 4 outputs for controlling servos or as logic outputs. Of course, all important lighting functions are supported. The brightness of each output may be adjusted separately. The decoder supports the automatic push and pull movements – known as the coupler waltz - required for reliable operation of digital couplers such as the ones by ROCO® and Krois® as well as Telex® couplers.Motor control of the LokSound 5 has been further improved. A variable PWM pulse frequency ranging from 10 kHz to 50 kHz assures perfect silent operation, particularly for coreless motors. Thus the typical hum is a thing of the past. Load control can now be adjusted with up to 10 separate CVs and thus will manage even the most difficult cases. The unique “Auto Tune” function facilitates the automatic calibration of the decoder to perfectly match the motor. The LokSound 5 decoder supplies up to 1.5A motor current, which is quite sufficient even for older motor types.

Great upgrade to my class 37

Clash of the Thrash!

Comparing The "Original" to the "Refurbished" for acoustically challenged hearing like mine was largely an irrelevance but there's no denying that whacking both on at full chat made a wonderful sound almost guaranteed to annoy the neighbours though in my case it's simply payback for their appealing taste in music. . !! Don't have a Bachmann 37 to compare to my glorious 37s but I can't think it could be any better . I note some have questioned the "Horn " sounds as a bit tinny or weak. I must say , I thought not. Only slight issue is Engine Cold Start function which I can't get to work but suspect user error . Otherwise an extremely satisfied customer!

Class 37 Original Sound decoder

Great decoder, luckily the less than careful handling by dpd didn't impact its operation. Perhaps an outer box rather than an envelope would be a better packaging solution


Excellent decoder and sound file, really like the cold start.
