Lighting the Room At Summit

10/20/2020

0 Comments

 
Picture
Lighting was the last major piece Lambda designed and installed for Summit Church earlier this year. It made an incredible visual difference and impact to their main room. It was so much fun to see this design come to life and how incredible it looked. 
For a more in-depth case study, we asked Brad Helzer, our main systems schematics designer, to write a little about what building the lighting system for Summit looked like:
“Summit Church was such a great project to work on. It presented unique challenges and a need for a fresh update in their look. The first thing I noticed when looking at the room for Summit is how wide it was. I imagine all the church attendees also got the feeling they were far away from the people on the other side of the room due to the width. So, to mitigate some of that width in the room I wanted to design something that had a central focus and moved outward from the stage toward the audience. With this in mind, we chose to use truss flown from the ceiling on a raked angle to create the sense of height and a dynamic depth for lighting fixtures to be hung from.

Backbone of an Audio System

​A Walk Through Summit Audio System

Picture
​The backbone of the Summit audio system is Dante. Dante is an Audio-over-IP protocol that allowed us to create an audio system that was both functional and reliable, but also gave Summit church the ability to grow and change as the situation dictated now and down the road. 
Now, an Audio-over-IP system is only as good as the network it is built on. Most Dante enabled devices allow you to run gear on two separate networks, a primary and a secondary, at the same time. To make sure we built in as much redundancy as possible, we ran the entire system with a complete separate secondary network so that if one network failed at any time, there would be a backup. So, let’s go on a virtual tour of the system!!
At Front of House we replaced the Midas M32 with a Yamaha CL5. This brought them from 32 input/16 outputs to 72 input/24 outputs! A big change to say the least. We didn’t get rid of the M32 however, but we’ll come back to that later.

​Summit Video System Continued

Picture
​The last part of the Summit video install we wanted to highlight for you is the thing that catches everyone’s attention. Let’s talk about the LED wall video screens!

Summit has two in room video screens. The first is a 2:1 aspect ratio main screen mounted to hang above the back of the stage. With the main screen being a 2:1 aspect ratio, this allows Summit Church to shoot their content in a more cinematic format and display it natively in the main room without image loss or resizing. This format was a great choice to work easily with the other video equipment for the church.
The second piece of the video screens is a lower LED wall that is split into six columns along the back of the stage. The lower LED wall columns offer a unique option for environmental videos and graphic during worship and speaking. They are primarily used for video and visual aesthetics to create the right ambiance for the church. The original plan for the lower LED wall

Designing a Broadcast Room

Summit Video System Continued

Picture
In addition to adding new audio visual equipment, Summit also decided they wanted to create a broadcast room. We were excited to help them design and add a fully equipped broadcast room for them. Not only are the video switcher, camera control panel and live streaming equipment in the broadcast room, but Summit also moved their audio console there to control stream audio. There are a lot of elements to the broadcast room at Summit and is a visually exciting little room to see!
Picture
​You might be wondering why it’s an important decision to add a broadcast room. Do you really need it or does it just add another layer of complexity? A Broadcast room allows for multiple people such as your Producer, Director/Switcher, Camera Shader, broadcast Audio Engineer, etc. to all be in one room and easily communicate with each other. Creating noise or talking is no longer is an issue like it would be if you had all these people at FOH. The broadcast room also uses two Danley cube speakers and a nano sub for live audio monitoring.

Covering All theVideo Angles

9/23/2020

​As promised last week, we wanted to jump right into the exciting camera system we installed for Summit Church in Denver. If you know Lambda, you know we have a few Video experts on our team and nothing is more exciting than playing with new video equipment all day!
Picture
​The camera setup at Summit comprised two Blackmagic Ursa mini broadcast cameras, a Blackmagic Pocket 6k, and two onstage 4k Marshall cameras. The main goal of any camera in a production is to be able to capture the essence of what is going on in the room as accurately as possible. Whether the capture is used just for streaming or recording, the Blackmagic Ursa mini broadcast and Pocket 6k cameras excel in this. You’ve probably heard us mention them before and, as you’ll see, with good reason! They both have fantastic low light capabilities and a wide dynamic range. This is crucial during a production as there is often a wide variety of bright and dark areas on the stage from special lighting. These cameras also integrate seamlessly with Blackmagic’s ATEM switchers (Click HERE for more about the switcher!) and Camera Control panel.
​One of the two Ursa Mini Broadcast cameras we set up on a tripod for tight follow of the main presenter and the other one was placed on a dolly track for capturing creative moving stage shots or a variety of other pans.

A Constellation at the Core

Summit Video System

Picture
​The biggest piece we did at Summit Church was designing their video system. It’s a large system, comprised of many different pieces, but in the end, they all work together to give Summit Church the ability to accomplish their vision and goals for the church. So, what are the different pieces of this system?

​First, let’s take a look at one of the most important pieces to the video system! The Blackmagic ATEM Constellation 8k could be described as the key piece of the entire video system. It gives you 4M/E’s, 4DVEs, 16 Keyers, 4 media players, 4 multi viewers, 2 SuperSorces and features 24 independently routable 12G‑SDI outputs. It may not seem or look like a very exciting piece of gear, but this little black box it is what allows all the other parts in the video system to work. It’s the glue that holds everything together!

From Mevo to Multiview Cameras Made Easy!

How one church went from one camera to a directing multiple cameras

Mountainview Christian Church contacted Lambda through the recommendation of another longtime client. Just a week or so prior to the COVID-19 lockdown, we had begun to work with them to draw out some ideas for improving their livestream. Mountainview had been using a MEVO to capture their services, but knew they needed something better. Mevo works by using a single camera that can track faces and create multiple images the same shot. This option can work great for small meetings, but not for a full worship meeting in a medium size church. 
Mountainview was accustomed to a lot of angles but wanted to add more quality to their captures. With this in mind, we built them a switching system based around a small Blackmagic rack switcher, a broadcast style Ursa camera and few smaller POV style cameras from Marshall. In laying out this system Matt Waresak, a camera specialist at Lambda, worked to ensure the stage was covered from every angle. ​

Simple Stream Upgrade

Forestgate Presbyterian Church, another church affected by covid-19 and unable to meet in person, turned to Lambda for a solution to connect with their congregation. They hoped to be able to have a quality way to connect on a lower budget by using as much existing technology as possible.

We have worked with Forestgate Presbyterian church for many years helping them transition through several different major changes in technology ability. Several years ago we put in a projection system for lyrics and announcements in the main area for worship. We also helped them set up a “cry room” to allow families with fussy children a comfortable place to sit where they could see a camera view of the service and the projected lyrics. The “cry room” system used a small black magic design block camera mounted on the back wall of the main room. This camera fed an HDMI signal into the building system, but also had an SDI output that wasn’t used.

Hey guys! Trevor here, shop manager and lead install tech for Lambda, and overall Audio Genius (That last one is a bit of a self-given title… but I’m keeping it). Along with working for Lambda, I am also an Audio Engineer for at a local church in Colorado Springs. Last week with the beginning of shutdowns due to COVID-19, most of the live production world came screeching to a halt. This included auditoriums and houses of worship. So, we wanted to share how we took a 2500+ group of people meeting over a weekend to an online only platform in a matter of 36 hours. ​

Case Study~Douglas Valley Elementary School

One of our favorite installs...

Picture
Douglas Valley Middle School, from District 20, came to us with an audio problem in their gym. The school had an aging audio system. The cables were a mess, no one really knew how to work the system, and it wasn’t really serving the school’s needs. We asked the PTO what they were using the gym for and the needs were pretty simple. The school staff needed to be able to hold an assembly, play music for gym classes and connect audio from a DVD player for movie night. The gym also doubles as a theater with a small stage for school programs and activities. The PTO and teachers also specifically requested a system that didn’t require them to know audio theory or reference big training manuals. They were looking for a quick, simple and effective fix.
Picture
With this in mind, we decided to focus on simplicity in the overall design. The school staff was not interested in learning to use a complicated sound board so we decided the first step was to eliminate it. How can you have a sound system with no sound board? Welcome to control systems! Specifically to Symetrix. Symetrix supplies control system DSP units that are configurable with wall panels to support a number of functions. We used the Solus line with 8 inputs and a 5” wall mount touch screen.  ​
On our site visit we noticed the speakers were also aging. They weren’t getting the sound coverage they needed and most of the time the quality was so bad, nobody could understand what was being said. This made school gatherings and events complicated and frustrating. Naturally, we looked to our good friends at Danley for a new speaker powerful and durable enough for a school gym, and with a cost conscious of the school PTO budget. The Danley OS12CX loudspeakers fit the build perfectly and then added a new line amplifier from the manufacturer Lea Professionals to power them. With better speaker design and placement, we were able to ensure that the entire room was covered with sound.
