What is it? How and When Do You Use it?Welcome to Trevor’s Audio Master class. I will be your guide to the wonderful world of Compression. The definition of a compressor is, “An audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range.” I’m sure that cleared up any confusion on compressors. Any questions??  Ok, but seriously. These are questions that we often get when we are doing sound training. What is a compressor? How do you use it? When should you use it?
Easter is just around the corner and it’s a good time to talk about making AV Goals. Audio Visual systems are an investment for your business, but sometimes it can be hard to make the final decision on when or how to invest in new equipment. How do you know which areas to invest in your AV system and what things can wait? This is where a little careful planning can take you a long way.
 In the middle of the pandemic, we all suddenly learned how good our video systems were or, in a lot of cases, were not. For New Life Church, a large multi-site church in Colorado Springs, Colorado, the video demands of a pandemic were high. A church of five separate locations citywide, with a moderate streaming presence, suddenly became a church with one location broadcasting five services. Along with the five services and all their other events turned virtual, they were broadcasting almost around the clock.
We’ve been looking at a series of cable and equipment testers recently. These tools help give us ideas when troubleshooting systems and how to proceed. If you know a cable is bad it is much easier to replace it than your other pieces of equipment. So, here’s another cable tester we use and love!
You simply plug each end of your cable into the appropriate connections and turn the knob to check each pin connection. LED's confirm each conductor continuity and connection status of each wire. This is such a useful tool for us! It allows us to check every connection we terminate before we install that cable on any job site. If we are having an issue with a cable this is a quick and simple way to check and make sure that the cable is not the problem.
It can be really helpful to have cable testers as part of your toolbox. They can save you so much time and sometimes turn a seemingly big problem into a simple fix. You know the rule about sequels…They’re never as good as the original. But we are hoping this can be closer to “The Dark Night” and less of “Jaws 2”.
We love getting new tools in our pelicans, so we wanted to share what’s new in our toolbox.  We realize that sometimes you just want to make a simple cable swap or another easy change on your own. At Lambda our main mission has always been to empower people to know their equipment and be able to get the most out of it. This is why the team at Lambda has been working hard to create resources for you to use this last year, including instructional graphics for camera operators.
We want to continue to provide practical tips for you to use so your company and staff can continue to grow. So, be sure to send us any questions or topics you’d like to see addressed here or on social media. Also, be sure to keep reading future issues as we have a lot of DIY tips coming up and if you haven’t heard about our jobsite guide, we’d love to get one into your hands! More to come!  In the video world over the past 20 years there have been many, many different types of cables and connections used to pass signal from one medium to another. From composite video to VGA and DVI, and now at SDI and HDMI. But while we have heard of these cables, what are they? And what do they do? Today we’re going to talk about HDMI and SDI.
If you follow us on Instagram, you’ve probably seen our Support videos. Not only do we want you to know the quickest way to reach Lambda if you need some help, but we want to make sure you have a place to turn when something goes wrong! We love designing and building AV systems, but we also love empowering YOU to use your system and keep it going for many years to come!
