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.

Class 37 sound decoder

Excellent item sounds great with many functions

Class 37 Sound

Bought the chip after originally purchasing a none DCC version of the loco. So easy to fit and the sound is superb! Perfect!


I missed out on a sound fitted 37. But having thr decoders separately available to purchase- i havent missed out. The sound quality is phenomenal. The aggression of the 37 thrash is captured here.
I look forward to fitting my 3 other 37s
Instaltion was easy and straight forward thanks to the new design with the roof lifting off.

Great sound

As expected from Accurascale, this sound decoder for the Class 37 sounds great and costs slightly less than some of their competitors in this market. Highly recommended, if like me, you love the roar of a 'Tractor'.

No ratting as you ran out of the speakers

See above so not used yet


Sound quality excellent. Only thing that would change is when sound decoder running on engine the Horn is not loud enough when other loco are running.

Christopher G.

Too early to review

Cannot give a proper review until it is fitted with a speaker, the sugar cube removed and loco is programmed
