Do you remember?
In 1981 the UREI compressors and filters were a popular choice for controlling levels and creating special effects. The LA-4 was a single-channel, half-rack unit with a patented electro-optical attenuator. It offered selectable compression ratios, a large VU meter, adjustable output and threshold levels and stereo coupling.
The 1176LN was a peak limiter that featured adjustable input and output levels; individual attack and release time controls; selectable compression ratios; switchable metering; and stereo coupling.
The 1178 was a two-channel version of the 1176LN in a 2RU package. It featured tracking in the selectable stereo mode as well as selectable VU and peak reading meter ballistics.
The original designs of the UREI products have been duplicated by current manufacturers, and there are even some processing plug-ins to replicate the sound of the original devices.
That was then
The WOWO transmitter site, located in Roanoke, IN, was built and began broadcasting in 1953. This photo was taken sometime during the early- to mid-50s. The Westinghouse transmitter to the right is a 1953 Westinghouse 50 HG. This is actually a 100kW short-wave transmitter that was modified to accommodate the needs of WOWO at the time to produce the 50kW signal. Due to these modifications, the transmitter actually contains a backup modulator and RF section housed within the cabinets. When the transmitter is running, only half of the tubes in the modulator and RF cabinets are illuminated. The backup tubes can be put into service by changing a knife switch within each cabinet.
This is still the current WOWO transmitter site. This transmitter is still in place and operational and can be used should the need arise. Throughout the years, the transmitter has been affectionately known as George, named after George Westinghouse.
Also in the photo are several equipment racks containing audio and remote control equipment. In the foreground is a backup studio used in emergencies and during maintenance periods.
