Four setups at the Science Fair

We set up four simultaneous audiovisual systems for this year’s Calgary Youth Science Fair, and – due to the coordination of the organizers – was an absolute breeze.

The judge’s zone

This cordoned off area is where the judges were able to discuss their votes over coffee and continental breakfast.

It was a relatively easy system, with a projector set on a stand and three speakers on stands around the judge’s zone. This is also the first time this projector screen had been used, and is one of two new 6′ x 8′ FastFold additions to our projector screen family.

We also had three inputs – standard auxiliary input from a music device, and two wireless microphone’s from the presentations. While the speakers were short in their presentations, we still wanted to ensure that they went perfectly.

Although the third speaker isn’t visible in any of these pictures, it had been daisy chained from the speaker on the right of this set up to the right side of this seating area. Withs its height and appropriate extension, it was able to provide audio to the whole area while not competing with any of the other setups.

The judge’s voting area

This was the smallest set up, which sat in between the judge’s zone and the main area. Here, judges from their specific science were able to discuss the projects and awards more privately.

The main area

We set up four three-way QSC towers, with the two nearest the stage (above) on crank stands, with the two speakers in the middle on the lowest setting of our standard speaker stands. This ensured that the speakers would be safe for those around them, yet would still carry sound enough to reach all of the audience in the stands.

Those familiar with the Olympic Oval at the University of Calgary will know of their in-house, widescreen LED display.

We plugged into a notebook used by one of the organizer’s. Unfortunately, this specific computer compressed the aspect ratio of the visuals intended to fit to the screen, but we were able to use our Roland V-4EX video mixer to fix the output from the video source to the LED display.

Here’s an underexposed photo of the visuals, but you will be able to see the effect, and use the top photo to view the original compression from the computer desktop’s visuals.

The science fair

We also ran an eight-speaker system throughout the science fair exhibition where the youth had posted their trifold presentations.

Because of the wireless microphone source, and the large, echoing, reverb-y hall, we ran an equalizer to take care of a few of the resonating problem frequencies. This was certainly mostly on the low end, and by punching the mids above the other frequencies, we were able to carry a loud and clear signal which was less prone to feeding back or rumbling.

We also set up two speaker pairs across the exhibition, which were high enough to carry the signal across the hall, but wouldn’t deafen any of the youth. Setting up eight speakers instead of four was a last-minute decision we made as a courtesy to the organizer’s of the science fair, and also as a way to further ensure that sound would extend as far as it needed to.

Also, here are just a few of the really amazing looking awards that they had available to the winning scientists who all brought a bit of their ingenuity and practice to the fair.

Congratulations to all of those who presented, and we hope to see you all again next year,

Olympic Projection

Filed under: Events, Industry Tips, Video — Tags: , , , — Kyle Napier @ 2:14 pm

We were able to hook up two separate video streams from the Olympics to two separate projectors last Saturday.

The first stream (left) was a simple setup. We ran VGA cable from our 3200 Lumen projector to a 30-pin iPod converter, and then to the iPod. We attempted running this system using HDMI as opposed to VGA, but realized that there was a screen compression in that conversion, so we stuck with VGA.

A few hours of recorded Olympics games was then streamed from the iPod, making for an easy setup.

The second stream (right) was a similar setup, but with a projector and screen that were provided by the client. However, the iPad that we were going to use to stream live Olympics coverage (as opposed to the recorded content from the first system) was not compatible with video – an issue with the first release of iPads.

Luckily, a friend of the clients was nearby with a more recent version of iPad, and we were able to start streaming content.

For sound, we simply ran a mixer per setup, using the headphone jack from both the iPad and iPod as the auxiliary input.

At last count, we’re number one on the Sochi Olympics 2014 Medal Count!

Go Canada!
