Tempe, Arizona, December 18th, 2007 — Circuit Research Labs, Inc. (OTCBB: CRLI.OB), parent company of Orban/CRL a worldwide leader in audio processing for AM, FM, TV, and Internet broadcasting announces that Kevin Clayborn, North American Sales Manager, recently made a trip to Malaysia at the request of Radio Television Malaysia and the Authorized Orban Dealer in Malaysia, Lightway Electronics, to conduct training on the operation of the Orban Optimod-FM 8500.Kevin Clayborn conducting training in Malaysia

While in Malaysia, Kevin visited several key broadcasters in Kuala Lumpur including AMP Radio Networks and STARfm. AMP is a privately run national network transmitting 8 different radio programs and several TV signals. STARfm is also a private national network, transmitting across the country in the Chinese language as RED and in the Malay language as Suriafm.

Radio Television Malaysia is the nationally owned and operated network transmitting in several languages across the country.

The training Kevin provided RTM engineers was in the city of Kuching, Sarawak, Borneo. Kevin held classes for 2 days at the RTM training center in Kuching for about 20 engineers. The class attendees learned how to install and set up the 8500FM for analog and digital operation as well as setting up and adjusting sound parameters to achieve the best sound for the listeners. This is very important to RTM as there is no set format on their frequencies and during the course of the day, several languages will be broadcast as well. Providing a clear consistent sound to all listeners is of paramount concern. The 8500FM has the power and flexibility to meet RTM's diverse needs.

While in Malaysia, Kevin visited with Balasingam Aruliah, CEO of Lightway and Ma Mil Foong, Director of Marketing for Lightway, who served as Kevin's guide and interpreter.

As Orban/CRL North American Sales Manager, Kevin is experienced and knowledgeable in the audio processing business. He was hired as Customer Service Manager by the late Ron Jones of CRL in 1993, and has worked within the Orban/CRL organization in a variety of key positions for the past several years, including Orban Customer Service Support Engineer.

Orban/CRL offers a sincere "thank you" to the broadcast professionals at Lightway and RTM, and to the people of Malaysia, for their hospitality.
