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!!

Staying in Touch

January 27, 2010, the first-generation iPad is unveiled at an Apple press event, changing the way we interact with video display devices in a profound way. While becoming wildly popular amongst adults, the iPad has also become standard equipment for young children who now grow up with a touch device in their hands from adolescence. Touch screens have been around for a very long time. As a matter of fact, the first touchscreen operated by a finger was developed in the 1960’s. However, the introduction of consumer based hand-held touch devices, over the last decade and a half, have had a profound impact on the way humans expect to interact with video display devices.

MicroTouch HospitalityIt is almost strange now if you come across a public display or kiosk and it is not touch enabled. In fact, I recently attempted to interact with a display kiosk, in a hotel lobby, only to find it was not a touch screen. As younger people that were raised with a touch device in their hands come of age, the expectation for interactive devices is higher than ever. We’ve also seen a shift in many areas to a self-service model, for better or for worse, and each will have their own opinion about it, but it is the reality. For example, when was the last time you actually dealt with an agent to check into an airline flight? It is now commonplace to check-in, receive your boarding pass, and receive your luggage tag all without human interaction.

Practically all the major fast-food chains now offer the option of ordering your meal via a touch screen kiosk, instead of ordering from a human behind the counter. Many supermarkets now have more self-checkout lines than traditional cashier-based check-out lines. Large chain restaurants offer the ability to pay your check through a portable touch display on the table. Even when I go to have blood drawn at the lab or visit my doctor, the check-in process is via a touch screen. Let’s not forget the ATM, one of the earliest mainstream uses of touchscreen technology that I can remember.

Outside of self-service, touch-enabled displays can be and are being used in various applications, including classrooms for learning, interactive gaming and entertainment, digital wayfinding, lobby directories, control systems, POS systems, automotive, corporate boardrooms, and more. There are many brands and many sizes of touchscreens on the market today. So, what separates one from the other? To me, it is the accuracy and responsiveness of the touch, along with as the physical aesthetics of the device itself.

There are several different types of touch technology, such as Resistive, Surface Acoustic Wave (SAW), Infrared (IR), and Capacitive – to name a few. PCAP, or Projected Capacitive, has become more available in larger sizes, and provides superior accuracy and speed of touch – and uses a glass top layer allowing for that smooth edge-to-edge glass look and feel. I will not go into the individual descriptions of each of the above technologies, but note that PCAP has become one of the most widely adopted touch technologies now that it can be used on larger displays and provides both great performance and aesthetics.

MicroTouch HealthcareTo enhance our offering of touchscreen technology, Exertis Almo has recently partnered with MicroTouch, who has been providing touch solutions for the market for over 40 years with installations in 80 countries and over 100 patents. MicroTouch offers a wide range of touch solutions, including open-frame models designed to fit into kiosks, desktop, large format digital signage, all-in-one (with computer), and healthcare solutions ranging in size from 7” to 65”. Their new MACH family takes performance and aesthetics to the next level with an ultra slim design, radiused corners, and concealed ports and cable management, coupled with a sleek edge to edge glass finish with a scratch resistant anti-glare surface. Add to this the speed, accuracy, and responsiveness of PCAP touch technology and a three-year advance replacement warranty. This new partnership will further enable integrators to provide high quality innovative touch solutions to their clients. Please visit www.exertisalmo.com for more information.

Breaking Down DVLED part 3 – Perfect Pitch

Part 3: Perfect Pitch

Topic: The importance of selecting the right pixel pitch the first time.

During my college years, I worked on a deck building crew during the summers. My boss was a battle-hardened old carpenter who often muttered, “Measure twice and cut once. We didn’t bring the board stretcher today.” This adage is as true in commissioning AV systems as it is in carpentry.

Let’s be honest, Indoor DVLED walls are expensive. And they should be!!! The visual experience is second to none, and it’s not close. Companies are concerned with getting their brand image and messaging across clearly and impactfully, and DVLED walls deliver. Assuming, of course, that the right product is selected.

If a client is dropping six figures on a DVLED display, it is critical that the integrator gets it right the first time. Putting up video walls is labor intensive enough. The notion of ever having to take a wall down because the customer was dissatisfied with the end result would be disastrous. And really, when it comes to DVLED, the only conceivable reason a client would be disappointed would be due to selecting a pixel pitch that was too large for the application.

customer communication

In the world of LCD displays or modern-day TV’s, most end users are primarily concerned with size and resolution. For example, a high definition (1080p) image will look the same—relatively speaking—regardless of image size, on a conventional LCD display from any reasonable viewing distance. The pixel density is so…um…dense…that any perceived “pixelization” will be negligible to the average human eye.

My friends, this is not so with DVLED. If you remember from my previous blog, Cabinets and Modules and Panels, Oh My, I described how DVLED pixels can be thought of as a grid of dots that make up an image. Think, Paint by Numbers. The more dots you jam into the same relative space, the clearer the image. Additionally, the closer you are to the display, the easier it will be to see the grid-lines. So, this would lead to reason that in order to produce a good DVLED image, you need the right amount of dots, in the right amount of physical space, that are viewed from the right distance.

pixel pitch vs resolution

Thus, I present to you the most important spec of all, when selecting a DVLED wall, the Pixel Pitch. Expressed in numerical values such as 0.7, 0.9, 1.2, 1.5, 1.9. 2.5, 3.7, 4.0 and so on, the pixel pitch indicates the center-to-center distance in millimeters of one pixel to the next. The smaller the number, the closer together the pixels are.

Now, I know we all love using handy math equations and standards in the AV industry, but unfortunately, selecting the right pixel pitch is a bit of an art. The most popular and generally accepted “standard” that is thrown around is Distance / 10. This means that to select the right pixel pitch, you need to take the distance in feet of the closest viewer and divide by 10. The quotient (aka. answer), should get you in the neighborhood of what an appropriate pixel pitch selection would be. For example, if the closest viewer is 10ft away from the display then the appropriate pixel pitch would be 1.0. Similarly, if the closest viewer was 25ft away the best pixel pitch would be 2.5.

viewing distance

Beyond this simple calculation, we need to go a little bit further and consider other factors like intended use, the type of content and the specific needs of the audience or viewer. In cases like retail or entertainment, where full motion video and large print will be the primary content and the average viewing distance and viewing range are very wide, pixelization is probably less of an issue. In an executive board room of a financial firm that will be using the wall to display smaller text, numbers and data or in critical medical imaging scenarios, it would be wise to opt for a pixel pitch that is perhaps a little smaller than the standard quotient.

Finally, let’s talk about cost. The smaller or “finer” the pixel pitch, the higher the cost. This means that a 220-inch video wall with a 2.5 pixel pitch could very easily end up costing more than twice that of a 3.7 pixel pitch of the same size. Similarly, depending on the type and quality of LED’s being used, a P1.0 could easily be two, three or even four times the cost of a P2.5 wall of the same relative size.

I’ve been around this game for a while, and I know we operate in a competitive landscape. It is sometimes tempting or even necessary to fit the solution into the budget. However, with DVLED walls, the repercussions of selecting a pixel pitch that is too large to fit into a customer’s budget could be dire. So, take heed. Or better yet, call me, and make sure you select the right pixel pitch the first time.

That’s all for now. Stay tuned for my next installment of Breaking Down DVLED:

Ingress Protection: the other IP of AV

When you hear the letters “IP“, most people probably think of Internet Protocol, Intellectual Property, or maybe even Innings Pitched.  Here, we are going to be referring to Ingress Protection, or how well an electrical enclosure can protect from the penetration of dust and moisture. Even if you have never heard the term before, you have most certainly thought about ingress protection at some time. Have you ever spilled water on your phone, tablet, or laptop?  That instant panic (and possible profanities) is caused by your lack of trust in the ability of your device to keep out moisture.

Most new cellphones are marketed as waterproof or water-resistant. What do those terms mean? Are they marketing buzzwords, or are they meant to be taken at face value? This video by CNBC does a good job explaining them. I have personally taken the term waterproof too literally myself. On my oldest daughter’s 1st birthday, we took her swimming and I wanted to document as much as I could with my “waterproof” phone. We had a great time, but the documentation did not go as planned. In fact, I learned a new notification that day. A water droplet icon meant that moisture had made its way into my phone, and it was no longer functioning properly.

How did these standards come to be? In 1976, the International Electrotechnical Commission, or IEC, published IEC 60529, with the goal of standardizing the requirements regarding protection by enclosures. Prior to that time, there were separate standards for motors and low-voltage switchgear and controlgear.

The IP rating consists of two digits:

  1. The first rates protection against solid objects and works on a scale of 0-6.
  2. The second rates protection against liquids and works on a scale of 0-9.

The guide below lists details of what level of protection each number represents.

IP ratings chart

Outdoor displays should have a rating of no less than IP55, to be reasonably safe from both dust and water. Using the above guide tells us that the first numeral of 5 means that the enclosure is considered “dust-protected”. Since we are fully in pollen season in much of the country, strong protection against solid foreign objects is necessary. A first numeral rating of 4 would not supply the necessary protection against pollen grains as they are smaller than the 1.0mm size listed in the description. The second numeral of 5 means that the device is “protected against water jets”.  Who is going to be blasting an outdoor display with water jets?  Well, a landscaping sprinkler system or someone using a hose are both water jets you would want to be safe from.

Samsung Terrace Outdoor qn65lst7tafOutdoor installations have progressed from your run-of-the-mill bank clocks with time and temperature to complex direct view LED displays that are truly immersive.  Keeping the viewer immersed, and not the hardware, is a key to the success and longevity of any outdoor AV project.  When your electronics are exposed to the elements, you will always have some degree of risk involved.  Using the IP ratings, along with the manufacturer’s suggested usage and accessories, will allow you to minimize risk for your projects and customers.  Be certain to read the warranty as well to ensure you are not doing anything that might void or shorten your warranty period.

Samsung Terrace Outdoor SoundbarOutdoor displays can range from a standard TV in an enclosure designed to be outdoors, all the way up to massive dvLEDs that you might see in Las Vegas or Times Square. Whatever your needs, Exertis Almo can provide solutions that run the gamut, including multiple dvLED vendors. The Samsung Terrace Series (consumer) provides options for outdoor displays, a soundbar offering, as well as accessories that can help protect and prolong the life of the hardware.  These have become quite popular in commercial settings such as bars, restaurants, hotels, and even corporate patio areas.

Edition 5 of “This May Be a Dumb Question, but…”

This Blog Series is written by Exertis Almo's Business Development Managers: 
Ashley Nichols, CTS, DSCE, and John Borns, CTS, DSCE.

If you’ve been following along with our blog series for the past few months, you may have been led to believe that the only questions we ever get are related to projection systems. Who could blame you? You’ve obviously read 3 straight issues of our critically acclaimed mini-series on projection (edition 2, ed 3, and ed 4). Well, I hate to break it you like this, but you’d be wrong. We get all sorts of questions – and maybe you shouldn’t go around assuming things so much. 🤣 Maybe we shouldn’t have dedicated 80% of our blogs thus far to 1 topic. 🤔 There’s no way to know for sure. Anyway… Today, we’re going to talk about AV racks! Another seemingly mystifying part of the AV ecosystem that we’re going to try and make sense of for you.

QUESTION

John, Are these rackshelves/lacing bars/drawers compatible with my rack?
or… John, I have 8 pieces of gear. What size rack do I need?
or… John, How do I know if these pieces of gear will fit in my rack?

ANSWER

These may appear to be different questions, but in actuality, they all stem from not knowing the same basic principles about AV racks. Questions like these are very near and dear to Ashley and me, because we asked a lot of these questions when we first started working together at Middle Atlantic Products many moons ago. We totally remember what it was like trying make heads and tails of how racks work and how everything goes together and what goes where. It wasn’t until a kind soul (shout out to Jason Pavia!) came along and totally bailed us out and taught us how everything works. The beauty about racks is that they are actually very straightforward because there are rack STANDARDs in place.

Firstly, let’s talk about the width of the rack1. Every rack (as far as I know) is 19” wide between the rails. So, anyTHING that wants to be rack mountable is going to conform to that width. Power strips, amps, shelves, mixers, you name it – they’re all going to be that width (or have some additional rack mount hardware that allows to it to cover that space). You pretty much never need to worry about whether or not something will fit into a SPECIFIC rack, because all racks are same size.

The second thing to know is the RACK UNIT2 (or RU as it’s more commonly referred to). A rack unit is always 1.75” high…but that doesn’t really even matter, because everything that is going to be mounted onto a rack must confirm to a solid RU measurement. So those amps, power strips, drawers, etc., that we mentioned above, are all 1 RU, 2 RU, 3 RU etc. So, knowing all of that, you can confidently assume that all of your rack mountable gear will fit in whatever rack you end up going with AND you can determine how tall of a rack you need by simply knowing how many pieces of gear you’re putting in there and how many RUs they occupy.

The last thing consider is the depth of the rack3. This is where the standards sort of dry up. The main thing to concern yourself with here is the depth of your DEEPEST piece of gear. You pretty much just need to make sure that it’s deep enough to accommodate that one piece, with a little extra room for cables and air flow. So, if you have a 20” deep UPS, you’ll probably want to get like a 24” deep rack.

QUESTION

How do I know which type of rack to choose? Wall-mounted? Gangable?
Why would someone need one vs the other?

ANSWER

I’ll admit that no one has asked me this question exactly, but it is an amalgamation of a general overwhelming feeling people have when trying to start looking for a rack. There are a TON of options out there and knowing which ones to use and when can feel intimidating at first. This is really where understanding the needs of the system and users is critical. Most racks are built with a certain type of application in mind. Let’s hit on a few of the common ones and why people would want to consider them.

wall-mountable rackWall-Mounted Racks – There a few different uses here. Mainly, if you have smaller rack need…something like 8-10 RUs….it may be easier to access the gear for use or service by having it hanging off of the wall at eye level. Bending down or kneeling to get to the gear can be an unwanted nuisance, especially if the gear is being accessed routinely. Additionally, maybe you want to keep the gear away from small people with bad intentions – kids. Wall-mounted racks are used in classroom applications. Also, simply having the rack secured to the wall can save space in some locations and may help keep a cluttered closet a little more organized.

Gangable5 Racks – This is really just a way of describing racks that can be fixed to one another in a row. If you’ve ever infiltrated a high security data center to get access to the heavily guarded corporate secrets, then you’ve undoubtedly seen a bunch of server racks “ganged” together. This allows for multiple racks to sort of operate as one larger unit, allow for cables to pass more easily between one another, save space, etc. Additionally, maybe you have a small system now, but one to potentially expand in the future. Getting gangable rack will allow your system to be scalable…to expand into a second rack down the line.

AV rack2-Post Racks vs 4-Post Racks – Generally speaking, in AV applications, you won’t commonly use 2-posts racks. These are typically used in network-based applications with thinner patch panels and lots of wire management needs. 4-post racks are sturdier and can handle heavier AV gear like your amplifiers, DSPs, Mixers etc. Also, 4-posts racks can be more easily built into larger cabinets, which gives them additional options that may improve your system. Speaking of which…

Other things to considerSecurity, thermal management, additional storage, etc. I’m certainly not going to be able to do these additional considerations justice. Racks that can have fully welded side panels, and lockable doors are much secure than those that don’t. Some racks are better equipped to manage the heat in the rack (which is critical to control if you want to preserve the life of your gear). Some racks have more room inside the cabinet, or can accommodate special accessories, making it much easier to mount small devices and power strips. Knowing which of these features are critical for your project will help guide you towards the right rack. Luckily, we’re here to help guide you if you need some help!

Vocab Test Time!

Are these the most detailed definitions? No – we are not a dictionary, nor the AVIXA CTS Prep book. Will someone message us after still telling us how much we missed? Possibly. Will these get you a basic working knowledge of these terms and why they matter? We hope so. Plus, we are 99% sure they will help you impress your grandparents when you reset their WIFI. 🤔

  1. Width of rack – always 19”, doesn’t matter the rack.
  2. Rack Units (RUs) – 1.75” per rack unit. Describes the height of a rack and rack mountable gear.
  3. How deep is your rack – Make sure it’s deeper than your deepest piece of gear.
  4. How deep is your love? – I really need to know…
  5. Gangable – Racks that can be easily connected together.
