Las Vegas, NV 04-09-2007 NAB SHOW — On January 20th, a landmark broadcast inaugurated a three-week residency by the renowned Cleveland Orchestra at Miami’s Carnival Center for the Performing Arts. The event was the first live broadcast on WCLV of the Orchestra from outside the Cleveland area.

Two Audio-Technica AT4047/SV large-diaphragm cardioid condenser microphones were employed by Robert Conrad, president of WCLV FM in Cleveland and the radio “voice” of the Orchestra since 1965, and Mark Hart, his counterpart who co-announced the event, which was also heard on Miami’s NPR station WLRN FM and other stations in Dallas, Indianapolis and Buffalo. Additionally, two AT4073a line + gradient condenser (shotgun) microphones were used for the performance at the Carnival Center’s John S. and James L. Knight Concert Hall. The event was also recorded by Bruce Gigax, longtime recording and broadcast engineer for The Cleveland Orchestra, using 24-bit audio to hard drive, for later replay as part of the Orchestra’s 2007 national radio series. Audio-Technica microphones will be a key component of The Cleveland Orchestra’s future broadcasts from Miami, which are scheduled to continue as part of the Orchestra’s 10-year residency project.

The AT4073a microphones were chosen by Gigax to accommodate the architecture of the new Knight Concert Hall. He decided that the corners of the Knight Concert Hall’s canopy over the stage would be the best location for a pair of high-end shotgun microphones to capture the hall’s exceptional reverb qualities. “The AT4073a’s were just perfect in this application,” he says. “I could add or subtract the shotgun gain on the mixer, add a little reverb to get just the right amount of ambience for the live concert in the hall. The 4073’s were clean, quiet, and we never had any trouble with them clipping, even when things were loud and the crowd was cheering loudly. Everything came through really smoothly.”

Host of Cleveland Orchestra broadcasts for the past 42 years, Robert Conrad has been the commentator for an orchestra broadcast series longer than anyone else in the history of American radio. Conrad commented: “We have the same microphone at Severance Hall for doing Orchestra concerts from there — and, in fact every microphone at WCLV is Audio-Technica, so we have a consistent sound on all of the Orchestra broadcasts and on the WCLV air sound. It’s a natural, warm sound,” Conrad says of the AT4047/SV. “There are no artifacts in it, it doesn’t emphasize bass, it doesn’t emphasize treble, and it gives a very accurate picture of what I sound like. They’re great microphones.”
