About this book
Audio and video adapters and couplers are the smallest, most overlooked components in any signal chain, yet they are often the first point of failure. This handbook is a field guide and reference manual rolled into one, written for people who need to get the job done right, whether that means wiring a conference room, setting up a touring rig, or installing a permanent broadcast facility.
Inside, you'll find a breakdown of every major connector and adapter family, the specifications that actually matter (impedance, insertion loss, shielding, gender, and pinout), and a practical decision framework for choosing the right part for the application. The book covers installation best practices, routine maintenance, and step-by-step troubleshooting for common failures like intermittent connections, hum, and signal dropouts. It also includes a dedicated section on the business landscape — who the major manufacturers are, how their products are positioned, and how you can build revenue through reselling, service contracts, private labeling, and consulting.
This is not a catalog and not a marketing piece. It is a neutral, technical reference designed to sit on the bench, in the van, or on the desk — and to answer the questions that actually come up, whether you're a seasoned professional or a serious enthusiast just getting deeper into the craft.
Reader Reviews

★★★★★I picked this up because I'm tired of guessing which barrel connector is going to hold up on a permanent install. The chapter on specifications is exactly what I needed — impedance and insertion loss finally make sense in context. It's not a thrilling read, but it's honest and technical. I just wish it had a few more photos of the actual connectors in hand, but I get why a printed book might not have room.

★★★★★Solid reference. I'm an A/V tech for a university and this book sits on my desk now. The troubleshooting chapter is practical and matches what I see in the field. The part on business opportunities was a bit beyond my needs, but I can see it being useful for someone starting a side gig. As a straight technical reference, it's very good — just don't expect glossy pictures.

★★★★★As a home theater hobbyist, I found the premise super helpful. The book doesn't talk down to you, but it also doesn't assume you have an engineering degree. I really appreciated the explanation of why a cheap HDMI coupler can cause signal drops. Four stars only because I feel like the glossary could have been bigger with more terms that you actually run into at the hardware store.

★★★★★I do live event production and have tossed far too many 'just in case' adapters into a bin over the years. This book helped me think about what I actually need and why. The breakdown by application is smart. It's not the kind of thing you read cover to cover in one sitting, but as a bench reference it's worth the money. A few more real-world failure case studies would have pushed it to five stars.

★★★★★This is the kind of book that should be issued with every AV cart or install kit. The first chapter alone clarified the difference between a coupler and an adapter for me professionally — I've been saying them interchangeably for years. The material on maintaining and cleaning connectors is gold. It's a bit dry in places, but for this subject, dry and accurate is exactly what you want.
