For over five decades BTX has helped the AV and IT integration community overcome technical hurdles. In addition to distributing a wide-ranging line card of trusted manufacturers, BTX holds several patents and has developed a full-service manufacturing division (copper, fiber, metalwork) to augment our value as a partner to your business. Our integration products range from essentials like bulk cable, adapters, connectors and tools… to networking and signal processing, conferencing and collaboration tools, and emerging technologies.

It is our mission to be your partner of choice by supplying valuable products, services, ideas and solutions enabling you to achieve your goal of world-class systems integration and maximum profitability.


Since 1979, we’ve turned millions of music makers like you into friends by delivering uncommon service and unparalleled expertise. Our dedication has helped Sweetwater become the #1 online retailer of pro audio and music instruments in the United States.



Getting our customers the best products for the best price is one of our key strengths, and service is no less important. We want you to get the most for your money while shopping with us, and therefore we have devised our own credo: Added Value. For instance, we’ve been offering a general 30-Day Money-Back Guarantee since 1995 – long before the EU came up with the directive on mail order purchases. On top of that, in 2005 we decided to offer an extended warranty period of three years – out of our own pocket! Happy customers make us happy in turn, and we appreciate the family atmosphere that prevails in our shop.



The corona crisis, which has had a huge impact on the musical instrument and audio industries, has changed significantly in the past few months, and we have been hearing a lot of news about the resumption of events from all over the country. I feel that we are steadily moving in the right direction toward a world where people can enjoy music events without hesitation, just like before. Last year, due to sudden fluctuations in the exchange rate and soaring prices of various materials, we were forced to raise the prices of everything, but we still receive a lot of support and encouragement, and our customers continue to use Sound House on a regular basis. We would like to take this opportunity to thank all our customers.

2022 was a big challenge year for Soundhouse. It can be said that this year has been a year in which we have been striving to realize our corporate philosophies of “local revitalization through music,” “connecting people through music,” and “bringing smiles to children through music.”
