Have you heard our WOW101-Steam Decoder?
The WOW101 has extraordinary sound quality and sound functions in a slim package with a 9-Pin JST connector on the front and with an auxiliary 7-Pin harness on the rear. WOWSound decoders can be purchased with or without Keep Alive™. When purchasing with Keep Alive™ there is over a ten dollar savings from separately purchasing the WOW101 and the KA2 Keep Alive™. The WOWSound decoder price is $94.95 (SKU #1516). With Keep Alive™ it is the WOW101-KA $109.95 (SKU #1517), more than a ten dollar savings over purchasing separately!

Here's what customers are saying:

"Best sound decoder in the world!"

"TCS has set a new high standard in sound quality and features."

"Audio Assist™ is AMAZING! It is so easy now to set up sounds!"

"Adjusting the chuff timing with Audio Assist™ is so quick and easy it's a miracle!"

"The TCS dynamic chuffs add such realism any other brand is just boring."

"The sounds are so crisp and clear!"

"When I compare the TCS bells to other manufactures it sounds like the others are wrapped in duct tape."

"TCS Keep-Alive™ technology is awesome; I no longer have resetting sound decoder problems!"
