If you’ve spent any time behind a console, in a booth, or backstage, you know this feeling well. The lights stop responding. A video signal refuses to appear where it’s supposed to. A strange hum suddenly shows up in the PA five minutes before doors. Troubleshooting is one of those universal skills in audio, lighting, and video — no matter your role, your venue, or your experience level. And while every system is different, the way you approach a problem matters just as much, or possibly even more, than tools you have in front of you. Recently, we surveyed 15 industry professionals across live sound, lighting, broadcast, and theatre. Different backgrounds, different disciplines — but their advice lined up almost unanimously: When you’re troubleshooting a problem, follow your signal path and only change one thing at a time. It sounds almost too simple. But this mindset is what separates efficient problem-solving from panic-driven cable swapping. Follow the Signal Path Every technical system — audio, lighting, or video — follows a logical signal path. And when something goes wrong, this is where disciplined troubleshooting really matters. As you move through that signal path, the rule stays the same the entire time: only change one thing at a time. Not one change per device. One change — then test. Start at the beginning of the signal chain and work forward step by step. At each point, ask yourself two very specific sets of questions: Do I have signal here? And just as important: is it the right signal? Do I have power here? And again: is it the right power? Those questions alone will eliminate a huge amount of guesswork. Once you’ve answered them, you can then ask the next burning question: Where exactly does the system stop behaving the way I expect? That’s how you narrow down the problem instead of chasing ghosts. When you make a change — swap a cable, adjust a setting, move a patch — test it. If it didn’t fix the issue, change it back before moving on. This keeps your system in a known state and prevents you from stacking changes on top of each other. Working this way might feel slower in the moment, but it’s dramatically faster in the long run. You stay oriented, you stay calm, and you always know what actually helped — and what didn’t. One Change. Then Test. Here’s the part people know… but don’t always follow under pressure. Change one thing. One cable. One fixture. One channel. One setting. Then test. If it didn’t fix the issue, change it back. Only then do you move on to the next change. Why is this so important? Because changing five things at once might feel faster — but it guarantees confusion. If the problem suddenly goes away, you won’t know which change actually solved it. And if it gets worse, you won’t know what caused that either. Systematic troubleshooting gives you clarity. It turns a stressful moment into a controlled process.

Step 1: Plan Your Cable Paths Before you start plugging things in, take a moment to plan your routes. Run cables in straight lines where possible, and try to avoid high-traffic areas. Running your cables along walls, and the backs of set pieces or risers often make for cleaner, safer paths. Even in the best setups, it’s not always possible to avoid crossing where someone might walk. That’s where gaffer’s tape earns its reputation as a tech’s best friend.

When it comes to procurement for professional audio, lighting, and video services, is it possible to balance the “best price” and “best service”? We think it is! Below are some insights that may help you navigate this challenge. The Challenge of Price-Driven Procurement Many municipalities and organizations are required to purchase from the vendor offering the lowest price. But is this approach always the best? As taxpayers, we want assurance that public money is being spent appropriately, and that there’s no room for favouritism or backdoor deals. The intent is good, but in practice, this system often results in a “bare bones” solution. The theory behind it is to guard against preferential treatment or collusion, ensuring that public funds are used responsibly. However, focusing solely on the lowest price can often result in solutions that are less than ideal.

It certainly has been different times dancing on Zoom for over 2 months. Now we are coming up on a new dance season. Everybody has different levels of confidence in returning to activities and that is perfectly fine. Some kids can not wait to get back in the studio. Some want to continue but would like to do so from home. Of course, depending on class size there may be a rotation where you spend two weeks in the studio and one week at home. Maybe you will dance in the studio like normal (with new physical distancing guidelines) but want to practice at home. With these new situations Rosco has made a kit version of their popular dance floor called the Marley Mat . The floor that is used in the Rosco Marley Mat is a lighter weight version of Adagio floor that we use in our studios. That makes it perfect for dancing at home for all types of dance including ballet, jazz, acro, lyrical and even tap . It will have the same feel and “speed” of the studio floor. Being a lighter weight material allows the floor to be rolled up when not in use and unrolled and used immediately. The Marley Mat kit can be purchased for $ 149.00 (price current as of July 2020) plus shipping and tax. The package comes with a 5’ 3” by 6’ section of black or grey floor, and a roll of tape that would allow you to lay down and tape the floor 5 times. Additional tape can be purchased. You can find and purchase the kit from StageStore at the following link. StageStore is a great supplier in Ontario of theatrical type products. https://www.stagestore.ca/product/rosco-marley-mat-kit/

Even with the proliferation of wireless systems, our entire industry runs on wire.  Miles, or should I say kilometres of wire. But the truth is that we use a lot less than we used to. Back in the 1980’s we didn’t have digital audio snakes or DMX cables for lighting. And every video line was a coax cable or multiple coax bound together. A simple audio snake could be an inch in diameter for just a couple dozen channels. But that was then. We’ve come a long way in the last 30-40 years, but we still run a lot of wire. It’s just different now. So, how much wire does go into a world class theatre? For the last six months Horizon Solutions’ crew has been pulling wire into the new Tom Patterson Theatre in Stratford, Ontario to support the new Audio and Video systems. There is a lot of wire there. To be clear this wire does not include the lighting systems, nor does it include the cables that plug from plates into the pieces of equipment. Those are a completely different story.
