Concert Production and Mobile Staging at Budweiser Biergarten

The day could not have been more beautiful. It was overcast, 70 degrees and the beer was flowing. The event, “Concert for a home” was organized to raise money for the Fort Collins Habitat for Humanity and was the first of its kind. Featuring performances by Blue October, Parachute and Kenzie Culver. One dollar of every beer sold went to the amazing charity.

Rockfan was a proud sponsor providing concert production, and a mobile stage. Our first event at the Biergarten was a success with over 1,000 tickets sold.

Acoustic Treatment

We visit many restaurants and breweries in Colorado that have poor acoustics. Acoustic treatment is extremely important to allow guests to easily communicate with one other and hear any source material such as music or a TV with out it seeming “too loud”.

Acoustic energy needs a place to go or it will build to unmanageable levels. Keeping acoustics under control will create a comfortable environment for guests and subconsciously encourage them to stay a little longer.

Sound Reinforcement for University of Colorado Boulder 2017 Graduation

Providing sound reinforcement for graduation ceremonies

This event proved to be a challenging yet extremely rewarding one. Our good friends at Blazen Illuminations (http://www.blazenlights.com/) hired us to help supplement sound reinforcement for the Colorado University of Boulder’s 2017 graduation. The main graduation takes place in Folsom Field, afterwards each college breaks out and hosts their own graduation ceremonies.

We were excited for this event because it would be the debut of our recently purchase QSC Wideline8 System. However, debuting this system in a tent is far from ideal.

One of my concerns was having ample gain before feed back and smooth even coverage from front to back.  The front row was roughly 10 feet from the loudspeakers and the back row was roughly 80 feet. From front to back I had the potential loss of 18dB! Based on the inverse distance law, which states a loss of 6dB every doubling of the distance.

Although tents are not acoustically ideal, they proved to act in our favor for speech. The reflective surfaces, and domed tops acted as a natural horn for our loud speakers.

QSC Wideline8 EASE Model by Rockfan Entertainment

The PA was made up of four Wideline 3082 per side, sitting atop a single WL212 and two GP218 dual 18″ subwoofers. The subwoofers were mainly used as stands to get the array to the needed height. Using EASE we focused the array to nearly flatten out on the top two boxes. In the photo to the left the minimal array curve is shown.

With the predicated coverage in EASE and the reflective surfaces of the tents the coverage was beautiful! From the front row to the back speech was crystal clear and intelligible. This was also the case with soft talkers, a type of person I’m always concerned about at speaking events, such as graduations.

Overall it was a successful event and the Rockfan Team worked hard and delivered another great production! Both of our stages utilizing this QSC Wideline8 configuration received praise for clear, intelligible sound throughout the tent. Our other 2 stages outfitted with QSC KLA12’s went off without a hitch as well! Thanks again to Blazen Illuminations and RC Events for the opportunity!

This light certainly gets the job done- it is SUPER bright. With tons of programmable colors, it works great in static mode, or when controlled via DMX.

However, I have a few issues with this light. The mounting bracket on the back is not the most durable and I’ve seen several of mine bend throughout the last few months. In addition, the pins that attach this bracket to the light itself is not very resilient and I’ve had a few of them pop off during transport or teardown; leaving the light attached to the bracket on only one side. This leads to extra time spent on maintenance, which gets annoying.
I do like the daisy chain features you get with PowerCon connectors. This makes your lighting truss look a lot cleaner, since you don’t have a ton of power cables running down the sides of your build. I also enjoy the ability to use different clamps in conjunction with this light, since I’ve used them on both 12” box truss and smaller lighting trees. These are great for colorful stage lights, or supplementary event lighting for outdoor use.

QSC CXD Review

QSC CXD

This amplifier makes all your hopes and dreams come true. With 3 models avalible, the CXD line will fit any job!

SO many features to talk about. First, you’ve got Flexible Amplifier Summing Technology (FAST) which allows you to power your outputs however you see fit. Need 4 independent outputs powering several types of speakers? Done. Need all of your outputs to be summed in order to drive a big subwoofer? Done. Got a bunch of 70V speakers in the ceiling of your bar/restaurant? Piece of cake. The flexibility of this amp is staggering.

Another great thing about this amp is the on-board DSP. All of this can be configured on the LCD touchscreen on the front of the unit, or through the Amplifier Navigator App available for download on QSC’s website. You can set EQs, compression and limiting however you want. BUT, if you want to use QSC’s presets (there are dozens of them) you can find one that matches the speakers you’re driving. That’s right, this amp comes with presets to optimize the sound of tons of common loudspeakers. All of this is right out of the box.

I really like the interface on this amp too. You’ve got a choice to use the full screen of your computer with the Amplifier Navigator, but the LCD on the amp itself is pretty intuitive if you don’t have a laptop with you. There are tons of ways to customize everything like amp presets, profiles and lockouts. Always great to password your amp if you don’t want an install client accidentally changing your settings. The icing on the cake is the ability to put your own or your client’s logo on the standby screen so they can be reminded of your great install work!
Installs for me would be a totally different experience without this awesome product, so of course it gets 5 stars!
