There were few studio spaces as historic as the second-floor digs of Infinity Radio’s KNX(AM), Los Angeles, in the venerable Art Deco Columbia Square building in Hollywood that once served as CBS west coast headquarters.

How many radio people can say they walked down the hall past a space where a live audience once watched Jack Benny do his show in the 1930s and ’40s?

All that history, however, couldn’t make up for the challenges of actually operating an all-news station from such antiquated facilities.

“All the news actualities were on cart, and with that all the inherent problems with audio quality and frankly, just keeping cart machines running these days,” said KNX/KFWB Chief Engineer Paul Sakrison.

The layout left much to be desired, as well, with a long walk down two busy corridors separating the cramped newsroom from the studios. So when CBS announced a few years ago that it planned to sell the building and move its occupants, which also included KCBS(TV) and KCAL(TV), few tears were shed.

Settling in

KNX’s sister all-newser KFWB(AM) also had been operating from Hollywood, in a 1970s-era studio facility built by former owner Westinghouse in what had once been a supermarket.

After briefly investigating a move to CBS’ Radford studio lot, where the TV stations are moving, Infinity Radio decided to incorporate KNX and KFWB(AM) into a 130,000-square-foot facility shared with three Infinity FM stations (KTWV, KLSX and KRTH) along L.A.’s “Miracle Mile” of Wilshire Boulevard.

Construction in the two-story space, formerly occupied by E! Entertainment Television, began in early 2004 with a near-complete gutting. The three FM stations occupy the second floor, with the two AM stations getting most of the third floor. On the east side of the third floor, a large open space is filled with sales cubicles and offices. The west side – some 30,000 square feet – is home to news and operations for KNX and KFWB.

At the heart of the new operation are routers and consoles from SAS, including three frames of SAS 32000KB routers that are “just about full,” says Sakrison, and 27 Rubicon consoles, which fill the 25 studios. (The main studio for each station has two consoles).

Sakrison praised the flexibility of the SAS system for its allowance of on-the-fly reconfiguration of those consoles, often from a laptop connected to the facility’s wireless network.

“This was the largest project to date for SAS,” said Howard Mullinack, director of strategic development for the supplier. “It utilizes six SAS 32KD digital audio mixer/router frames providing a total of 3,072 inputs and outputs, with 37 Rubicon consoles.

“All-news and talk formats are by far the most demanding in terms of features, inter-communication requirements and custom control features,” he said. “For the all-news studios, SAS integrated the main 40-slot consoles with five smaller consoles that each have the ability to take themselves directly to air, reducing the workload of the main host at the console. Every console has a fully integrated intercom to all other consoles and editor stations.

“The architecture of the system provides extensive back-up and distribution of resources to eliminate single-point-of-failure concerns.”

Shared space

As befits longtime competitors now under common ownership, each station has its own side of the studio floor. On the north side, facing Wilshire Boulevard, KNX’s studios ring the outer portion of the floor, though with corridors buffering the traffic noise from outside; while KFWB’s studios form a near mirror image on the south side.

At the core of the facility are the two stations’ newsrooms, with a zig-zag wall separating them. Each newsroom features a raised area for the editors, overlooking a line of desks for writers, anchors and reporters and the main studios beyond them. A pass-through window connects the editors’ desks of both stations, allowing them to share information when needed.

Sakrison says sightlines were of key importance in the design.

“The anchors can see everyone they work with, from the editors to the traffic reporters to the talk show hosts,” he said. “The writers are between the main anchor studios and the editors’ area. Seven LCD TVs are mounted above the window to the main studio, including a 37-inch HDTV, which most of the newsroom faces.

“The feed desks are right next to the editors’ raised area so live feeds can be coordinated face-to-face, which is needed when things are hectic during breaking news and election nights,” he said.

Workflow was another consideration. Sakrison says while each studio is slightly different, similar rooms have the same basic equipment laid out in the same order, minimizing confusion in the fast-paced all-news environment at each station.

Each station’s newsroom and studios also feature a color-coded decorating scheme: KFWB, as the flagship station of the Los Angeles Dodgers, gets walls and furniture painted light blue, while KNX’s walls and furniture are painted a soft green.

A distinctive feature of each studio is the colored countertop, which Sakrison says serves an acoustic purpose as well. “The countertops are covered with Marmoleum, normally a floor covering, which has a little bit of give to it, which dampens sounds from contact with the countertop. While the floors are carpeted, in the areas where the chairs roll, we also applied a lighter shade of Marmoleum,” he said.

The stations now share a common newsroom computer system, the NewsBoss system, running on more than 100 new Dell desktop computers. Sakrison says the move from reel-to-reel tape and carts to the digital audio editor integrated into NewsBoss brought about big changes, especially at KNX.

“There’s a learning curve, but we’re able to do stuff we could never do before,” he said, such as multi-track audio editing, an integral feature of NewsBoss, and the ability to easily share audio between the stations. Audio highlights of KFWB’s Dodger games now reach KNX’s audience directly through the NewsBoss system, instead of being recorded to cart from an off-air pickup of the KFWB signal, as they were at the old Columbia Square studios.

The new studios also make heavy use of JK Audio’s Innkeeper PBX hybrids, for small phone-interview rooms. Behind the scenes, a new AudioVault automation system handles non-news audio.

KFWB was the first of the two AMs to move into the facility, arriving June 24 to join the FMs that began moving in this past spring. KNX was the last of the five stations to make the move to the Miracle Mile, closing out 66 years in Columbia Square with a special hour-long broadcast Aug. 12, followed by the sign-on of the new Wilshire studios.

Unlike the typical move, in which engineers hope listeners won’t notice anything different, Sakrison says this one was meant to be obvious to the audience: “When we moved, the quality of the station’s sound changed. It became considerably better.”
