KUNV Goes Back to School

        Radio on FacebookJoin us on Facebook

KUNV returns to the campus of the University of Nevada, Las Vegas as part of the Greenspun Hall project.

Designing for performance

The performance studio is intended to be the site of many live and live-to-recoding performances tapping into the available musicians who make Las Vegas their home or performing base. The recording control room houses a Yamaha O2R96 console and is designed for 7.1 surround sound production with seven Genelec 8040A monitors and a 7050B active subwoofer. Editing can be accomplished with Adobe Audition 3.0 and a Sony 32" WEGA LCD flat panel display stand-mounted directly behind the audio console. Additional audio sources can be handled in this studio with a Tascam DA-40 DAT recorder and MD-350 MiniDisc recorder along with a Marantz PMD325 CD, Denon DN-780R cassette, and Gemini XL-120 turntable.

In addition to musical performances, the performance studio is designed for interview programs. A custom-built interview table has ample room for a host and three guests with Rode NT2000 microphones at each location on Mika Yellowtec arms and a Rane HC 6S headphone amp centered and flush mounted in the table top. Normally positioned to look directly into the recording control room, the interview table can be rolled to the side of the studio when a musical performance is under way. The performance studio also houses a baby grand piano and has an isolation booth for drums or soloists depending on the recording requirements.

Two edit suites were built using mostly repurposed equipment from the old facility. Centered around Mackie mixers (1642 and 1202 VLZ models), the suites have Electro-Voice RE20 microphones, JBL Control 5 monitors, Telos One telephone interfaces, Denon DN-C635 CD players, Tascam DA-30 MKII DAT recorders and some additional miscellaneous equipment. Production work is accomplished using Adobe Audition 3.0. Although the edit suites were intended primarily for student production projects, they also provide KUNV with additional studio spaces for basic voice-over production or telephone interviews.

A central TOC is shared by both radio and television and houses 46 Stantron Broadcast E-Rack units; each 45RU × 36" D. Radio equipment currently is located in four racks with additional racks available for future expansion or new equipment. Wiring throughout the facility is carried in over-head wire trays and is a combination of fiber, coax, and CAT-6. To transport audio and data from the studio facilities to the transmitter location, we chose a Dragon Wave Horizon Compact system. With 300Mb/s throughput, this system allows us to transport our digital audio stream uncompressed from a local Axia node to another node at our nearby mountaintop transmitter site. From there an AES connection runs to an Omnia 6 EXI, which not only processes our analog signal, but will also act as an HD1 processor for our main channel. An Omnia One will handle the HD2 processing, which is scheduled to be on-air next summer. Finally a BE10S transmits our signal through a three-bay antenna located on Black Mountain, giving us city grade coverage of the Las Vegas valley and most of Henderson, NV.

As a broadcaster, it isn't often you get the opportunity to have a say in building a new radio station from the ground up and when you do the process can be daunting, but when the finished facilities meet the goals and expectations of all involved it's a great feeling. Today, KUNV serves the UNLV campus and the Las Vegas community from state-of-the-art facilities and it truly is a great feeling.
