 At Lambda we have a lot of fun working with clients across the county and if you know us, you know that we have a passion for helping people get the most out of their AV system! We are all about getting equipment that will serve your specific purposes for many years. Usually, we show you fun gear and installs from our perspective, but we thought it might be interesting to show you things from another perspective. Questions you might be interested in when it comes to planning upgrades before you even begin working with us or just what other churches are doing. We will be showing you a few interviews over the next few months to hopefully answer some questions you might not have even thought to ask. We decided to do a quick interview with a long-time client to get their perspective on working with Lambda and how we were able to provide them with the tools they needed to grow! Summit Church is a mid-size church in Denver with a ton of life and energy. They did a major upgrade with us about a year ago so that the tech could really match what the church itself was already doing. Hopefully, this interview can give you a practical, realistic look at what it’s like to work with an AV Integrator for your business.
How would you describe your role at Summit?
“My job is to bring Pastor Rob Singleton's vision to life. I make sure the teams and processes are in place and moving forward in the right direction.” Our take on the New M1 Mac  n my career in AV, I have seen several transitions with computers and though each one has been significant, this one might be my favorite. In an effort to test and experiment with new equipment, as we always try to do for our customers, I purchased an M1 iMac and gave up my barely one year old highly spec’d intel MacBook Pro… and I haven’t looked back. If you aren’t familiar with the M1 apple products, it’s a new chip designed by apple. This chip takes on an entirely new hardware design and in doing so really pours on the performance. The big adds are what is called ARM-based RISC computing, along with on-chip graphics processing, and on-chip memory. Basically, the computer is able to access more of its resources quicker. What does this mean for you and me? Here are a few great use cases I have seen on my own.
 The last form of Keying we wanted to highlight is Linear or alpha keying. Linear or Alpha keying is the evolution of the Luminance key and Pattern keying (read HERE). Linear keying becomes a basis for where we can build almost all advanced keying. It typically requires special hardware and software but gets you great results.  Linear keying is made from two separate signals. The first signal is called the Cut Signal. The Cut Signal is a luma-based signal of white, black, and grayscale that tells the switcher what is opaque (black) and where to put a GFX signal (white). The second signal is the Fill Signal or the actual GFX or colors. (Pictured above) The switcher uses the Cut Signal as the pattern shape, which allows the benefits of a luma key while eliminating the con of not being able to have things like a black outline. This is because the switcher is using one signal to say where things are opaque and another for what the actual content will be.
Luminance and Pattern Keys Keying is a powerful and essential feature on your video switchers. It's important to know the basics behind keying so you can really understand what is happening on your switcher when you use these features. We've talked about Chroma Keys, HERE, so now we want to highlight another similar switcher key: Luminance Keys.
 If you, like many over this last year, are new to pro video switchers, their terminology, and features you may be wondering about ME’s. ME’s are where the magic happens in video switchers and are comprised of controls each with a row of buttons for Preview and Program. Program is the video source you are sending out and Preview refers to the video source you are intending to transition into next. Let’s start by talking about what ME stands for. An ME stands for Mix Effects Bus. To understand what this is we will break down each word. First, we can start with M or Mix. Mixing is the combination of two or more elements. At its most basic function, a video switcher does just this by mixing different sources such as multiple cameras or a GFX source.  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.
