Bonneville Phoenix moves its three-station operation
The complexity of Bonneville Phoenix operation is apparent with just a short visit to the new facility. It would be next to impossible to operate as it is today had it remained in its downtown space.
Bonneville Phoenix uses Moseley Starlink fixed 950kHz STL units with Starlink T1 backups. All radio STL units are installed on the roof to reduce RF in the rack rooms and minimize transmission line runs. The units are housed in a DDB Unlimited Insulated Outdoor Rack, with a 6,000 BTU side-mounted AC unit. The Starlinks are lightning protected with feed-thru polyphasors, mounted to the lower wall of the rack and bonded to the master ground system.
Two alternating, redundant Liebert air conditioning systems consistently cool each of the rack rooms at 65 degrees, providing the best trade-off between air conditioning expense and extended equipment life. The closed room system takes in air at floor level and exhausts high. Dual-redundant APC UPS systems provide electrical protection for the entire technical core.
General studio design
Mohawk CAT-5e 350MHz 25-pair cables provide the backbone wiring for analog and digital audio from each studio, control room and voice booth, to and from the rack rooms. Cable trays are employed where required.
Double-pane ½" glass is used in many of the studios and control rooms with 16" walls, including ¾" plyboard layers and 1" sound deadening panels to enhance acoustical isolation and reflectivity inside each room.
Harris PR&E custom furniture was installed throughout the facility for a consistent look and feel. Harris studio design representatives provided insight and design advice to make each room more ergonomically correct.
The furniture designs are similar in many rooms. For example, the three KTAR talk studios all feature two host and four guest positions, a separate voice booth and an isolated master control room. Each host has a Harris PR&E Stereomixer digital console with logic control, Vistamax Source Selectors, dropped keyboard trays and Vistamax intercoms. The intercom system is tied to the Stereomixer consoles to provide direct communication to the individual talent positions.
Individual headphone controls tied to a Harris PR&E 3×6 headphone distribution amplifier are built into the guest positions, with Electro-Voice RE-27ND microphones overhead. The on-air master control and voice booth studios feature the same setup for news and producer positions. In the music wing, custom furniture in the main KPKX air studio and production/backup air studio has two host and two guest positions, with much of the same built-in technology.
Every studio also utilizes Humanscale LCD monitor arms providing flexibility in positioning the computer monitors. This is critical for producers and technical directors who rely on visual cueing and require an unobstructed view of the talent.
The jewel of the furniture layout is a six-station work facility for Web content editors that we call the flower. This is a six-position cluster where the editors face each other while maintaining some privacy in the workspace. Each position has a view of one of two 48" monitors showing alternating Web pages and TV news from around the nation. The Web content cluster is located in the newsroom so Web editors can immediately produce breaking news for the Web pages. Humanscale monitor arms used in the Web content cluster are also used throughout the newsroom.
Talk wing, on-air and production
Three studio suites are at the center of the KTAR-AM/FM operation: News/Talk 92.3 KTAR-FM programs news during morning drive from the news suite, also clearing games on the weekends, and programs both live and syndicated talk from mid-morning through the evening and early morning hours from the talk suite. Sports 620 KTAR-AM runs live, local morning and afternoon drive talk shows; clears live play-by-play and runs ESPN sports overnights from the sports suite. Each on-air operation has a dedicated on-air master control studio, talk studio and voice booth studio.
