studio moves happen quickly. Others, like the recent relocation of
Clear Channel’s seven-station cluster in Portland, Ore., are years
in the making.

were supposed to make the move back in 2008,” says Chris Weiss, the
cluster’s director of engineering, “but we had trouble finding a
an understatement, really. After struggling to find a site that met
all of the stations’ needs, Clear Channel ended up signing a lease,
only to find out that its new landlord itself hadn’t closed on its
purchase of the building. What’s more, the new location turned out
to be a haz-mat site, further entangling the stations in legal
battles that forced Clear Channel to extend the lease on its existing
studios in the meantime.
took several years for the lawyers to clear the way for a second
attempt at a move, and Weiss says it all came together much more
quickly this time.
Channel’s new home is in the top two stories of a four-story
building in an office park in the Portland suburb of Tigard.
negotiated the lease in January of 2012, so it was a pretty quick
turnaround of things, from saying yes, for sure we’re doing this,
to getting in here with hard hats,” Weiss recalls of his busy year,
which culminated in mid-October with the move of the last two
stations from Clear Channel’s old facility just south of downtown
Portland along the Willamette River.
about 25,000 square feet, the new facility is about the same overall
size as the old plant, but Weiss says the move allowed for much more
efficient use of the space. Clear Channel’s old studios had been in
use since 1978, when they were built for KEX(AM) and sister station
KKRZ(FM). Over the years, another AM station and two more FMs were
jammed into that two-story space, while two more sister FMs set up
shop in an adjacent building.

contrast, the new facility was designed from the ground up for all
seven stations at once. Studios for all the stations are located on
the third floor, where top-40 KKRZ (“Z100”) looks into the lobby
and its six sisters are all lined up along an interior corridor.

turns out to be a big cost savings, since we didn’t have to
triple-glaze or quadruple-glaze.”
addition to physical proximity, the new studios improved on the old
ones in another way. Because of the changing equipment needs in 21st
century radio, Weiss was able to make some of the new studios smaller
than their equivalents at the old buildings.
saved about 350 square feet from the studio that used to house the
full-service AM station (KEX), since you don’t need two tape decks
and an overbridge anymore,” Weiss says.
the new studios were built on two models: each of the five FM music
stations has a similar studio with four mics and a Wheatstone E-4 or
E-6 control surface, while each of the two AM talk stations has a
control room equipped with an E-6 and a talk studio with a Wheatstone
SideBoard controller, as well as an adjacent production studio that
can also serve as a news or sports booth.
production rooms for the cluster each use Wheatstone IP-12 consoles.
The total complement of Wheatstone gear includes 13 control surfaces,
56 WheatNet-IP Blades, 23 mic processors, and numerous panels,
turrets and support gear.
says the choice of Wheatstone was one of the biggest decisions during
the project. At the old Macadam Avenue studios, Clear Channel’s
stations had used a variety of consoles. Weiss says recent experience
persuaded him that his new facility would use some flavor of audio
over IP technology.

going back to 2005, figuring we’d be going into a move,” Weiss
recalls. “When Clear Channel in Seattle went Wheatstone, my
regional manager, Erik Kuhlmann, suggested I take a look at it.” He

the ability to move some mics over from the old studios. Beyond the
mics, everything was new, including Studio Technology furniture, Blue

says the phone system turned out to be one of the learning
experiences from the move; each VX Engine can handle 30 audio streams
at once (caller audio, mix-minus back to the caller and/or music on
hold), which proved to be not quite enough for seven stations running
at full tilt, especially when KEX moved over with its news people.

solved the problem, and Weiss says it has proved to be a worthy
replacement for the Telos 2101s at the old facility.
furniture involved another construction adventure. When the building
contractor failed to deliver power to the studios on schedule, Weiss
says Vince Fiola’s Studio Technology crew went to work anyway. “His
guys ended up having to install all the furniture with no power in
the studio. They did it with headlamps and those portable
construction lights,” Weiss says, but it got finished on time.
Luckett & Farley, who have worked with Clear Channel on numerous
studio projects in recent years, placed the stations’ tech core on
the fourth floor, which also houses a conference room that doubles as
a live performance studio and a large walk-out patio space.
addition to a homebrew Asterisk-based phone system and common EAS
gear for the entire cluster, the tech core houses individual racks
for each station’s NexGen systems and Wheatstone equipment.
at the new facility extend to the transmission architecture. Each of
the seven stations has two Wheatstone Blade IP access units, a main
and a backup. While the main Blade usually feeds a fiber distribution
system, the backup Blade automatically connects to the backup
microwave system, ensuring continuity even should the entire system
normal operation, Clear Channel’s new system routes Wheatstone’s
audio-over-IP over fiber all the way from the studios in Tigard to
the two hilltop transmitter sites that serve the five FM stations.
From there, for now, a backup path then goes by microwave to the site
southeast of Portland, where the two AM stations, KEX and KPOJ, are
located. That reverses the old microwave architecture, which went
from Macadam Avenue out to the AM site and then hopped to the FMs
from there; eventually, he’s hoping to get dark fiber all the way
out to the AM site.

had already been going down that road,” he says of the last few
years at the old studios. Fiber serving both FM sites suffered only
two outages in nearly a decade; by contrast, he says the T1 that’s
fed by copper to his AM site had already suffered five outages before
2013 was even half over.
move from Macadam Avenue to Clear Channel’s new home was completed
over the course of several weeks in September and October 2012, with
two stations moving each week. Weiss says the five FMs, which were
first to move, went smoothly, with things getting more complicated at
the end of the move when KEX and KPOJ and their larger staffs

with two weeks left on the lease and some help from out of town, as
Milwaukee-based engineer Steve George worked with Kuhlmann to
dismantle the old studios and put usable gear in storage to be
shipped eventually to other Clear Channel markets.
a company as large as Clear Channel, Weiss says the process of
working with other engineers on a big move is essential. Earlier in
2012, Weiss spent a week at Clear Channel’s Sacramento cluster
assisting with — and learning from — a similar move.

says, “but what did we learn as a company in this process? If we
can come up with solutions that could work for 75 percent of the
company, we can build templates on those, and create standards around
which we can build local options.”
