Stewart Audio Launches Low-Power Networked Amplifier Series

Compact, affordable Dante™-enabled amplifiers bring audio networking benefits to installations requiring lower channel counts for local amplification

SONORA, California, September 4, 2014 — The benefits of digital audio networking continue to extend past the mixing board and signal processing racks, bringing simpler connectivity, lighter infrastructure and improved flexibility and control to the amplification stage and beyond. However, most networked amplifiers today specialize in high channel counts for large installations, with amplifiers centralized in densely populated racks to serve global PA systems.

Stewart Audio today introduces a family of four low-wattage, networked amplifiers that address the need for lower channel count support at the local amplification stage. The new series brings the benefits of power-efficient digital audio networking to an underserved customer base, where consultants, systems integrators, dealers and end users require simple, affordable networked amplifier solutions scaled for smaller zones. This provides an affordable and reliable option to the larger, high-wattage amplifiers for high channel counts that permeate the market.

Importantly, the compact footprint of all four products enables simple installation at endpoints, providing networked amplification to smaller zones – whether for standalone needs in small-to-mid-sized installations; or to provide low-power amplification to smaller, distant zones in larger scale projects. Dual inputs in two models (AV25-2 NET+, CVA50-1 NET+) allow customers to serve both local and global PA systems if desired, with the option to target and prioritize pages and other audio events across many zones. This flexibility ensures that Stewart Audio customers can address larger facility needs while filling the void of local amplification requirements.

“To date, the market has lacked an affordable way to position networked amplifiers at endpoints,” said Brian McCormick, chief marketing officer, Stewart Audio. “Our new family of compact amplifiers create a cost-efficient way to run CAT5 or CAT6 cable to local zones, allowing our customers to enjoy the benefits of digital audio networking beyond the central infrastructure. These products give our customers a simple and affordable way to address a broad range of low power, low channel count applications without the expense of larger networked amplifiers, or the complexity of architecting custom solutions with bridge devices and analog amplifiers.”

Stewart Audio incorporates the market-leading Dante™ media networking solution from Audinate into its product architecture to enable many operational benefits. The incorporation of Dante Ultimo technology in all four products specifically addresses the requirement of affordable networking solutions for lower channel counts and lower power consumption. Compatibility with other Dante-enabled products is also ensured for a seamless, high-performance networking architecture across installations of any size.

Installations are further simplified with the presence of Symetrix Composer 2.0 software. Composer 2.0 software natively integrates device discovery and signal routing all four new products through its unique Dante third-party programming environment. This further reduces complexity for the installer, accelerating deployment times and creating a cohesive end-to-end Dante networking solution with local amplification.

The complete range of new Stewart Audio networked amplification solutions include:
• AV25-2 NET+: A 2x25W, 4 or 8 ohm low impedance amplifier with two analog and two Dante inputs, and remote and local volume control. Automated port switching can override audio feeds depending on which Dante or analog feed is set to priority.
AV25-2 NET: A digital-only version of the AV25-2 NET+ with two Dante inputs.
• CVA50-1 NET+: A 50W, 70/100V mono amplifier with one analog and one Dante input, remote and local volume control, and automated priority port switching to insert local audio feeds over main programs.
CVA50-1 NET: A digital-only version of the CVA50-1 NET+ with a single Dante input.

All four compact solutions can be pole mounted or attached to a flat surface near loudspeakers, and are plenum-rated to reduce the installation costs associated with rack-mounted systems. However, the 1/3RU design enables simple integration into central equipment racks if desired.

Yamaha Commercial Audio Donates Live System To Nashville HS

Pearl-Cohn Entertainment Magnet High School in Nashville, Tennessee offers students the opportunity to learn through the lens of the entertainment industry with pathways in audio engineering, broadcasting, record industry, marketing, and image consulting. It is the only entertainment magnet high school in the country. The vision of Pearl-Cohn is to equip its students to realize and achieve their potential while committed to educate the whole person.

Bryan Lenox of Lenox Productions facilitated the arrangement with Yamaha, who in turn, enlisted the services of J Sound Services (Nashville) to add a new Yamaha CL1 Digital Audio Console and Rio 3208-D input/out box to its 413-seat auditorium. Yamaha IS and DXR speakers, and TXn amplifiers were also installed. J Sound Services specified the system for its easy operation by student volunteers. Auditorium productions at Pearl-Cohn can be anything from assemblies with announcements and presentations that include video to full-on theatrical events.

J Sound Services has had a lot of experience installing Yamaha Installation Series Speakers, so they were the obvious choice for the installation. “Once we understood the scope of the project, we determined a Yamaha MTX5D processor and DCPS wall-mount controller would also be required,” states Jason Spence, owner, J Sound Services. The design approach was based on the fact that there is limited acoustic treatment in the school auditorium. “It was important to minimize the amount of energy on the walls, says Spence.

Time was spent using Yamaha’s YS3 Sound System Simulator and EASE acoustic modeling software to focus the mid-high and subwoofer-arrays. Deployed end-fire arrays both in L-R and Center allow pattern control on how wide the throw would be in the room and also provides a Cardiod pattern measuring 12db down on stage behind the arrays. “By deploying the subs this way we have significantly reduced the low-end energy on the stage and what would have reflected off the walls in a typical Omni pattern, Spence adds. The room can easily handle and extends below 40Hz without the low-end building up, leaving the room also very articulate and musical. The house is nice and big with lots of sub. The design is very unique and it clearly looks different. The staff and Bryan Lenox were quite impressed with the results of the end-firing arrays.”

Lenox assisted in the set up and adjustments of the CL1. “The system sounds really good. The school had a unique need for a system that can handle intimate speaking all the way to low-end thumping Hip Hop music. And, this system definitely delivers. The CL1 is a great sounding console and one that the students can learn on in order to prepare for the real world so they can jump into any situation with confidence.”

The new auditorium’s multi-purpose system is all Dante connected with the Yamaha CL1 taking control of presets for theatrical productions using the consoles Nuendo Live software. Pearl-Cohn ran cat5 cable to their multi-track room to record the events taking place in auditorium. A.Cisco switch is used to network and import multi-tracking in studio. An old projection booth above the auditorium now has the capability of adding a Nuendo recording suite with infrastructure and cables already in place.

“Our students needed professional-class live production facilities in order to complete our vision to equip our students with real-world skills that will transfer to the marketplace or college when they graduate, states Sam Lorber, Instructional Designer at Pearl-Cohn. Thanks to Yamaha’s generous donation, these students will now be able to walk into any venue: club, church, college auditorium, or arena with a skill set advantage no other school can provide.” The principal commented on how she loves that she can touch one button and it just works.

J Sound Services also installed a Vivitek High-Definition 6K lumen projector with remote HDMI interface. To update the theatrical lighting system, JSS enlisted the consulting services of Chris Lisle Lighting Design and installed Elektralite LED PAR fixtures, Watson raceway and ElektraHazer, an Altman spotlight, and Chauvet Datastream; all of which integrated with the existing ETC dimmers. As part of the lighting system update the existing Fresnels and Lekos were reconditioned and focused.

J Sound Services also installed four Yamaha C115VA and two C112VA Club Series Speakers using a MTX3 processor and the same DCPS wall-mounted controller as in the auditorium. Spence said the system installed could be operated in the same manner, with a touch of a button, making it extremely simple and consistent for staff and students to operate the systems in either location.

Southwestern Assembly of God U Installs Yamaha NUAGE DAW System

BUENA PARK, Calif.—Located in Waxahachie, TX, Southwestern Assemblies of God University (SAGU) began as a regional bible school and later, added a junior college program. The university has experienced phenomenal enrollment increases from 596 students in 1991 to approximately 2,200 today. In 2013, the academic divisions of the university realigned into three colleges: the College of Bible & Church Ministries, the College of Business and Education, and the College of Music and Communication Arts. All colleges maintain Bible-based curriculum to fulfill the mission of SAGU. Since 2000, SAGU has added 24 new academic programs, bringing the total to more than 60 programs.

Recently, SAGU added a 48-Fader Yamaha NUAGE Advanced Production DAW System, purchased through Audio DAWG of Irving, Texas. The system is installed in a dedicated studio for commercial production that is available for rental and an academic learning lab for Digital Media Arts students. Internships are being offered for students in the program, but they will also have to complete at least one major audio project using the studio, with staff engineer assistance.

“I started using Nuendo 2.0 in 2003 as an upgrade from Cubase SX which I was strictly using for MIDI programming, states John Cookman, Chief Engineer and Director of Media Services and Production. My DAW at the time was a PARIS system that had been discontinued, and I needed a DAW that could keep up with where I was leaving off. Wow! Nuendo really did that and more.”

Cookman purchased NUAGE primarily because he had grown tired of recording/editing/mixing with a mouse and keyboard. “I always sensed that my creativity was being stifled due to the inefficient ways of keyboard and mouse work flow, Cookman says. I had originally planned to purchase a Euphonix system because of its acclaimed integration with Nuendo, but once I demoed the NUAGE at NAB 2013, I decided it was much more practical to buy a console that was specifically made for the Nuendo platform and would also be supported by Nuendo’s parent company, Yamaha. From the first minute I sat down with the NUAGE, I have felt at home.”

The Digital Media Arts BA degree is the path for all of SAGU media students, and the department is moving toward an audio recording degree path. They do offer an audio recording class that is mandatory for all DMA students. Each student will be doing at least one project on the NUAGE. SAGU averages roughly 20 students in the audio recording class per semester.

Technically, SAGU is not a house of worship but they do have daily chapel services. “My department has started up a live and on-demand outlet to view and listen to services (www.SAGU.tv chapel channel), notes Cookman. This is a multi-camera and multi channel audio mix for broadcast TV using our DMA students as student workers. We also do sports broadcasting as well.”

Two main facilities are used for broadcasting, the largest auditorium seats approximately 2,300. During the school year the auditorium is occupied mostly by students. The other auditorium is a new performing arts theater seating 625. “Our NUAGE system is directly integrated to this room so that we can use it as a sound stage to record from,” adds Cookman.

Cookman appreciates the NUAGE state-of-the-art approach adding in the elements of the analog workflow to a digital non-linear workflow. “Now I am able to access the best of both worlds concerning work flow. Yamaha has done an outstanding job at connecting the user to efficient workflow systems. The way they have integrated NUAGE with the DAW (especially Nuendo) has empowered the engineer with hands-on tools that are unprecedented in our industry.”

Specific features that were attractive in SAGU’s decision process were the motorized faders, one-touch navigation to any parameter, and the ability to edit each parameter microscopically with professional grade encoders. “Faders and buttons impact our work environment everyday. Being able to reach over and instantly access channel data makes workflow so efficient. Now, I don’t have to spend time scrolling with my mouse and keyboard keeping me from really getting into that creative zone. The NUAGE is a “Must Have” for every DAW.”

John Cookman has been in the industry for 30 years, and 18 of those were spent in the non-linear DAW world. “Since I started working with NUAGE, I finally feel like I am tapping into the top layer of my potential as a engineer and producer. In May, we released a Christian music project for an outside artist (I was hired to produce and record/edit/mix). Within 45 days, we charted at #10 on the Billboard Hot Christian charts and the next week, we topped out at #8. The artist was the only independent artist in the top 100 at that time. I attribute a lot of that to the flexibility the NUAGE brought us to use more of our creative brain rather than engineering brain.”

Cookman says he is budgeting for a smaller NUAGE setup for broadcast remix in SAGU’s master control room currently using Nuendo.
