ISMRM Meeting & Exhibition - Another Success

Posted by: Tyler Robinson - Systems Tech on April 26, 2013


Poll Sound provided the audio reinforcement for the General Sessions of the ISMRM (International Society for Magnetic Resonance in Medicine) held at the Salt Palace this week.

The General Sessions were held in the Grand Ballroom and to cover the large area we let a portion of our L-Acoustics inventory handle the job. We used Kara line array modules for the main Left and Right hang, each array consisted of 9 cabinets. We also flew two more arrays for out-fills that consisted of 2 SB15's and 9 Kiva line array modules. And finally to provide a small amount of front fill we used three of L-Acoustics new 5XT enclosures placed on mic stands under the screens with one sitting on the lip of the stage. The 5XT's were a perfect fit and it was amazing how they were able to keep up with the rest of the PA even with their small size. All of the loud speakers were powered by LA-8 Amplified controllers.

Shure wireless and wired microphones were used on the Podium, Pannel and Q&A audience mics. A Yamaha CL-5 was used to mix everything together and make things sound great. The L-Acoustics amplifiers were also on the the network allowing me to control them from the FOH mix position. All amplifers were fed an AES signal from the Rio Stage box back stage; an analog back up line was also ran to each amplifier.

To help with tuning the system, I used Rational Acoustics Smaart. It received its information from the Dante Network using the Dante Virtual Soundcard; I was able to view and measure the audio of any channel on the mixer. Dante is amazing and eliminates the need of carrying an Audio Pre / Interface for tuning, the console becomes your interface. We have confirmed that SysTune will also interface with Dante Virtual Soundcard. We ran the control network for the amplifiers and Shure wireless down the same network cable as the Dante Network and had no glitches.
