Behind the Panel: Teaching an Old Dog New Tricks, or: How I Learned to Study Again!

Welcome back to “Behind the Panel.” For this edition, I thought I would delve into something truly relevant to most of us in the AV world: studying and preparing to take the CTS Exam. CTS (Certified Technology Specialist) is a certification process given out by AVIXA that is the industry standard in Pro AV. According to their website:

A Certified Technology Specialist (CTS®) performs general technology solution tasks by creating, providing, operating and servicing network-based AV solutions, while conducting AV management activities which provide for the best audiovisual resolutions of the client’s needs, both on time and within budget

When I arrived at Exertis Almo, my job description mandated passing the exam and becoming CTS certified. I had nine months to complete this task. This was a little exciting to me, as it is something I always wanted to accomplish. This was also very terrifying, as I had tried some of the online study guides in the past, but never got far. Topping all of that off is the fact that I have not studied for an exam in close to THIRTY YEARS! Thinking about that number gave me pause, and although I have always considered myself someone who learns and takes tests well, it has been more than a minute since I used my brain in this way.

First, I set a goal and a timeline: Although I had nine months, I wanted to finish it before the end of the year. My goal was five months, and I wrote it down, so I had to commit to it. Second, I spoke to two colleagues that had recently passed the test; taking detailed notes of what worked for them studying and recollections of what their testing experience was like. This was invaluable, because it let me know there was someone who just went through it and survived. Texas Instruments TI-30XS calculatorNext, I made two important purchases: the most recent edition if the CTS Study Guide, and a Texas Instruments TI-30XS calculator. Both are vital. It’s important to become familiar with the way the calculator works – I cannot stress this enough. I was eager and got started right away on the AVIXA website. Highly recommended, check it out. These courses are designed to give you a basic understanding of the concepts you will be learning and offer quizzes at the end of each section to evaluate yourself. I set parameters for myself that I would not move onto the next section until I could get a ninety-five or above on the quizzes.

CTS-study-guide-ed3This worked for three days, because on day four I went back and retook the first few quizzes. To my sheer terror, it was as though I never studied at all. I was having a difficult time recalling the previous info. Panicked, I did the worst thing I could do. I stopped trying. I was convinced that at my age, I could not just go in and memorize things the way I could when I was a college kid. My mind was not working the way I needed it to. I started reading about it, studies that have shown how just a general decline in cognitive abilities as you age could affect one’s ability to learn. Just for my own peace of mind, I went to my doctor and explained what I was going through, and after a series of cognitive tests showed I was doing very well cognitively speaking, I decided I needed to change the way I studied.

brain-powerMy approach was to hit my brain from all sides and try and load the information from a variety of sources. I used the online prep path, but at the same time, I started reading the actual book. Things started to stick for longer, so this was a positive sign. I continued doing this for a few weeks when I received some valuable advice: Book the test! Set a deadline and book the exam, because the worst case scenario is that you fail and use it as a practice test. I took this, ran with it, and scheduled myself to take the test in eight weeks.

I also concluded that I would need to set up rigid conditions to overcome my brain’s ability to retain new information. I needed a routine, so here is what I did:

  1. I set aside time and shut everything out. This allowed me to concentrate on what I was reading or looking at and focus solely on that. Ringer off, no emails, no TV. Luckily, my kids are older, so I did not have to worry about toddlers bursting into my office!
  2. I studied from multiple sources. This was a big part of my program. I would set aside a certain amount of time to read in the book, usually forty minutes to an hour. My next step would be to incorporate the online path to certification, again, giving myself a set number of modules to cover. As I got closer to the exam, I also incorporated the study guide that runs with AVIXA’s online CTS class. Which leads me to my next point:
  3. Don’t try and cram too much at once. This was a huge point for me, because when I would try and do too much, I ended up not retaining key facts. How do you eat an elephant? One bite at a time!
  4. Music or no music. I found myself listening to classical music when I was reading and studying. There are a couple schools of thought on this. Some say if you listen to music while studying, you will also need music to play during the test. There are other theories that music can activate both sides of your brain at the same time, which can maximize learning and improve memory. I chose classical music because there are no lyrics to distract, and it was helpful having that background noise because when it was pure silence, I felt I could not focus. The best answer is what works for you!
  5. Take a walk. I cannot stress how much this was a huge help. Before I would begin my study sessions, I took a walk around my neighborhood for about 20-25 minutes. I found that I came back feeling noticeably clear minded and it was much easier to focus. There is actual science behind this, as studies have shown that low-intensity exercise can provide a boost to energy levels – ideal for studying for lengthy periods. It has also been shown to improve concentration and help you focus your learning.
  6. Don’t stress about the math. Whoever I speak to now, if they are preparing to take the CTS, the vast majority tend to be very nervous about the math and formulas associated with CTS, which at face value can seem overwhelming. I have two things to say about that: First, while I cannot give exact numbers, when I took the exam, I only used the calculator a handful of times. Second, my colleague, Tom Kehr, has an informative video that helps you learn, understand, and retain AV Math. Check that out here: Math Prep. It is also worth noting that Tom was a huge help, who always made himself available to walk me through things I was not quite grasping. Thanks Tom!

My actual taking of the exam was delayed a few times due to extreme weather, but when I finally took it, I was noticeably confident going in. The worst part was having to take a survey before I received my results, which was probably the most stressful five minutes I can remember. I passed, which was a big accomplishment for me. If you are taking or plan to take, don’t let it stress you out, give yourself time to prepare, and you will do great! Thanks for reading, hope to have you back to read the next edition of “Behind the Panel.”

Behind the Panel: Cables, Cables, Everywhere!!

We are going to start today with a trip down memory lane… standard hdmi cableYou have just picked out a gorgeous new HD Television at one of the “Big Box” stores. You are super excited, because “Real Housewives of Buffalo” is premiering season 4 later that day, and you cannot imagine how fantastic it will look in your living room. Then the sales associate that helped you pick that display out asks you if you need a high-end HDMI cable to go with that display. He goes on to tell you that it will “enhance the viewing experience” and “provide better quality audio” for you. Do you spend the $75 for that cable? Or is the $10 one available on that XYZ website going to do the trick? Now, for you and your latest reality series, it may not make much of a difference, but when you are in the world of Pro AV, it can be all the difference in the world.

When it comes to setting up an audio or video system, choosing the right cables is crucial. While it may be tempting to opt for cheaper imports or consumer cables, investing in professional audio and video cables can make all the difference in terms of performance, durability, and reliability. Let’s look at the benefits of using professional audio video cables instead of cheaper online options.

Primarily, professional audio and video cables are designed by manufacturers to deliver superior performance. These cables are engineered with high-quality materials and features that ensure optimal signal transfer, reducing the risk of signal loss or distortion. broadcast videoThis translates into clear, high-quality audio and video output, which is essential for professional applications such as recording studios, live performances, and broadcasting. Whether you are setting up a live event like a concert, installing a conference room solution with high end UC equipment, or setting up a classroom or auditorium in the education space, investing in the higher quality product will help ensure the best performance. In comparison, cheaper cables may not be designed to the same high standards as professional cables. These cables may have lower quality materials and construction, which can result in signal loss, noise, or interference. This can lead to poor audio and video quality, which is unacceptable in professional settings. If performance is key, then you absolutely need Pro-quality cables here.
Something else to consider. Is that less expensive cable rated to do the job that you need? Wait, there are ratings for cables??? Why yes, yes there are. Cables have different ratings, which have to do with whether they can be used in-wall, riser applications, or plenum applications. These are different ratings based on shielding layers and fire resistance to help fires from spreading. If you use non-plenum cable in the plenum ceiling, inspectors will not give you an occupancy or building permit, and you may be subject to fines. Our partners at C2G have this nice guide about different ratings.

Another benefit of using professional audio and video cables is their durability. Professional cables are built to withstand the rigors of frequent use and transport, with features such as reinforced connectors, strain relief, and shielding. This makes them more resistant to wear and tear, and less likely to break or fail during use. In contrast, cheaper imports or consumer cables may not be built to the same standards of durability. These cables may have weaker connectors, thinner insulation, or less shielding, which can make them more susceptible to damage or failure. cable durabilityThis can result in frequent replacements and downtime, which can be costly and disruptive. Think of the time and money spent having technicians deployed just to replace cables, because they were cheaper at the outset. Those savings up front are costing you more down the road. What a huge waste! You absolutely cannot have an inferior connection break in the middle of a live performance or important video conference, which could have catastrophic effects on your business. Did you know that C2G offers a Limited lifetime warranty on all cable assemblies? They do, and that is just one of the many reasons we are excited to have them as a partner.

Finally, professional audio and video cables offer greater reliability. Professional cables are tested and certified to meet industry standards for performance and safety, ensuring that they will work consistently and safely under various conditions. This is critical in professional settings where failure or malfunction can have grave consequences. Cheaper cables may not offer the same level of reliability or safety. These cables may not be put through the same quality control measures and may not meet industry standards for performance or safety. This can result in unpredictable performance, safety hazards, or even damage to equipment. C2G Performance Series cablesLuckily, C2G has that covered as well. Take a look at their latest and greatest: the Performance Series, 100% tested at the production line to make sure it meets standards, highest standard rating required for in-wall installation, and many other key features.

I get it, we are talking about cables here, and I know it is not the forefront in technology, or the flashiest thing you will see at Infocomm – but without quality cabling throughout your AV install, all that equipment cannot run to its highest potential. Investing in professional audio and video cables is a wise choice for anyone who wants to achieve optimal performance, durability, and reliability from their audio and video systems. While less expensive or consumer cables may seem like an attractive option, they simply cannot match those results from professional cables. If you want pro results, you must use pro products. That is it for me, until next time we go Behind the Panel!!

Behind the Panel: Navigating Direct View LED Mounts

We are back again – this time talking about the world of Direct View LED mounts. First, let’s take a brief look at Direct View LED as a solution:

Direct View LED (DVLED) is a technology that has existed for some time, but the last five to seven years has seen an explosion in the amount of manufacturers that are producing DVLED technology. In its most basic description, DVLED is a display consisting of several light-emitting diodes (LEDs) mounted on a circuit board, creating each panel. These panels are then configured into a larger, finished display. The biggest draw to these is you can get a much larger overall display than traditional LED displays, which usually top out around 100” diagonal. This gives you much greater flexibility to create larger display sizes, and not be limited to the traditional shape of normal displays. They can be pyramids, curved, columns… really the sky is the limit. These displays are also much brighter than traditional LED. Take the TV in your home, more than likely that will be around 300 nits in brightness. Professional digital signage displays are usually in the 500-700 nits range. DVLED are very bright, most times in a range of 4,000-10,000 nits, and because there is no glass, (hence the term, “Direct View”), they will not have glare, as well as offering much broader viewing angles.

Assessing the DVLED Install Needs

Chief digital signage solutionsThe first step in the process is assessing the install site. The integrator will have to do a thorough site survey, to make sure the solution will work. Making sure they have adequate access to power, and ensuring that the wall or structure that the display is being mounted to is secure and strong enough to support it. Once you have this done, you can work on designing and planning your wall layout and structure. Most manufacturers offer assistance in design for the mounting solution. Our partners at Legrand have really simplified the process with a great Online Configuration Tool to help put your display together. They offer many in-stock solutions for the major DVLED brands. If your DVLED isn’t available in one of their preconfigured varieties, they offer custom solutions as well.

Selecting a DVLED Mount Solution

Now, back to the mounts. The first question that I am often asked, is why a customer would choose third party mounts when the DVLED manufacturer has mounts that are made for their own solution. Great question! The answer is simple:

  • DISPLAY manufacturers primary focus is on developing and manufacturing DISPLAYS.
  • MOUNT manufacturers primary focus is on developing and manufacturing MOUNTS.

Although the DVLED manufacturers’ mounting solutions will fit, they will more than likely not work as well as mounts made by a mount manufacturer. Usually, the DVLED manufacturer has a mounting solution that is a pretty basic, perhaps a simple frame with some brackets. Third party mounts are designed with installers in mind. They will be set up for easier installation because they give you the ability to make micro-adjustments after they are mounted. For installers, having the ability to make x-y-z axis adjustments help ensure a perfectly planar video wall. They are usually a much more robust mount all together, with more features that produce a better finished product, and also have the installer in mind by making installation quicker, more efficient, and allowing for easier access when servicing post-install.

To draw an everyday life comparison, think about buying a car. When you purchase a car, often times the dealer would throw in floor mats for your car. The floor mats were OK, they matched the color of the interior, and would keep some dirt and grime off the floor of the car. But you could also go buy a set of floor mats that were made by a company that does nothing but make car accessories, composed of heavier duty material, laser machined to exactly fit in your vehicle, and would keep EVERYTHING off the floor of your vehicle. Wow, after writing that, I really think I need new floor mats. Anyways, this is why I would look to a mount manufacturer to make DVLED mount solutions, it is what they do every day!

I also know there is a whole segment of resellers out there who are relatively new to this space, and Exertis Almo has you covered there as well.

Exertis Almo Labor Project Support

Whether this is your first DVLED install or you are attempting something cutting-edge, like a curved wall, Exertis Almo has a services team that can professionally install that solution for you. Our team has a wealth of knowledge and experience in DVLED installation and commissioning. Find out more at https://www.ExertisAlmo.com/install.

That does it for me, catch you next time… behind the panel.

Behind the Panel: Cameras for the House of Worship Market

Welcome to this installment of “Behind the Panel,” detailing everything you need to know about cameras for the House of Worship (HOW) market. I realize that this doesn’t technically fall “behind,” so, for this edition, open your minds and we will go “beyond” the panel. By now, I am hoping you had a chance to read my colleague, Rob Voorhees’, blog post, titled “Streaming into the Future; How Bandwidth Needs Have Expanded for Houses of Worship,” which focuses on dedicated bandwidth for the HOW market. If you haven’t, go now and I will wait here for you…

All caught up?? Fantastic, we are moving on! As Rob mentions in his post, streaming services online has been done for quite some time, but the COVID-19 pandemic really forced houses of worship to change the way they reached their congregation. Reading some statistics online, prior to the pandemic, about 40% of churches said they neither livestreamed their service nor posted online later. As we moved throughout 2020, more and more churches, about 65%, said they were streaming services, with 27% saying they posted a sermon online later. What does all this mean? To me, it means if your HOW is not streaming today, they should be ready to make that jump, because even though people have been making the transition back to in-person worship, the pandemic has shown value in making these services available online, whether to sick congregation members, or churchgoers all over the world, wherever they may be. Statistics from Lifeway research included here.

How do you get your local house of worship up and streaming? Well, you have a great start with all that extra bandwidth they have now, so let’s look at how to choose the right camera. We will be looking at PTZ (Pan, Tilt, Zoom) Cameras. Pan is the ability of the camera to move left/right of center. Tilt is the camera’s ability to move up and down. Zoom is the camera’s ability to move in and out, whether done digitally or optically with the lens. Keep in mind with digital zoom, you lose quality as you zoom in on the image. There are cameras that can provide 12X, 20X, 30X, or even greater optical zoom.

Here are some questions that need to be answered when specifying a camera.

What type of connection will be used?

There are many different ways, including HDMI, SDI, and USB. There are benefits to each, but one of the biggest differences is how far the signal can travel on each. SDI can send signals up to 1000 ft. without loss. HDMI can travel up to 50 ft. without the use of extenders. USB is limited to just a few feet. So, paying attention to infrastructure and the budget is very important in making these decisions. It is significantly less expensive to run a few hundred feet of coax cable for an SDI solution than adding extenders to an HDMI solution.

Now, these are great for places with a healthy budget, but what happens if you have a church that is still running on an older technology, like S-Video? Check out what our friends at Vaddio have done. The PrimeSHOT 20 was designed with the HOW market in mind. It comes with 20X optical zoom, 1080p @ 60 fps Resolution and an S-Video output. The camera can detect and downscale the image to S-Video, so you can upgrade the camera in a legacy system, and come back and upgrade the cabling at a later point! Check it out here: PrimeSHOT

Where / how far are you placing the camera?

Important to keep this in mind, because the last thing you want to do is choose a zoom level not high enough for the church’s needs. They may want a wide shot to get the whole stage, or focus on the speaker by getting in tight. Check out this Camera Selection Guide from Vaddio to decide what is best for your local HOW. Don’t forget, these cameras all come with compatible wall mounts, so you have that option right out of the box.

How are you controlling the camera?

Although they come with standard with an IR remote, most HOW will want to have a little finer control over their system. All Vaddio cameras can be controlled via a web browser interface, pictured here >

This gives them great results for a lot of basic streaming. If they are looking for a higher “production value” look no further than the Vaddio ProductionVIEW Precision Camera Controller. This gives the user a broadcast-quality joystick to control the PTZ aspects of the camera, as well as the ability to control up to seven PTZ cameras. It’s not for every church, but for those that are serious about streaming their services, it is definitely worth a look.

I think the important thing to keep in mind, like anything else, is listening to what the customer needs. It seems so simple, but digging in to really find those needs out, as well as identifying future what growth they may see in the future, will allow you to craft a solution that can be friendly to the budget, while, at the same time, giving opportunity for repeat business as they look to expand on the initial solution.

I will leave you with this case study from Heritage Lutheran Church just to show the vast potential for streaming in the HOW market.

Thanks for reading.

l look forward to any feedback you might have. Otherwise, see you next time, when I will venture back “Behind the Panel!”
