August press release - BCD Audio at IBC2002
Good Bugs from BCD
The BCD Audio "Jitterbug" is a compact, hand-held device housed in a robust belt-pack box, and provides many facilities previously only available from mains-powered bench test equipment.
Systems installers and maintenance engineers testing and debugging interconnections and equipment need to measure frequency, voltage levels and jitter in digital audio signals, and also view AES status flags and error messages.The Jitterbug has been designed to meet these requirements in an economic and ergonomically attractive package.
A simple menu system offers eight options, including an analogue headphones output switchable between left, stereo, right and mono operation. The high visibility LCD panel shows wordclock or sample rate frequency to 1 Hz accuracy, jitter to within 2nS and AES signal levels to 1dB resolution, with the option of a simple bargraph for AES signals. Levels may be measured at a higher resolution by using an external PC.
The BCD Audio "Humbug" is the complementary product to the Jitterbug, and uses identical packaging to provide a wide range of digital audio signals at various levels and frequencies. The output level ranges from 0dBFS down to -99dBFS in 1dB steps, with a preset at -18dBFS, and the signal frequency ranges from 2Hz to 20KHz, with a preset at 1KHz. Sampling frequency may be referenced to external wordclock or to AES signals or internally selected to 48KHz or 96KHz. A phono socket accepts external wordclock or sends out a TTL wordclock signal derived from internal or AES sources. The unit may thus be used to synchronise external equipment, and may be controlled remotely using an external PC via an RS232 connection.
September press release - Radioman interface
BCD Audio has received a contract from the Oxford Sound Company for over 80 sets of custom-designed changeover units which will provide a seamless transition from analogue to digital operation when IBM Jutel Radioman systems are installed in a major London broadcast centre.
The BCD unit can interface with at least three generations of audio console and enables the existing fader start mechanisms to operate the old and new system without requiring jumper or software changes. The unit switches all of the required logic and audio feeds between the two systems, facilitates dual-redundant operation of the new playout system, and interfaces the on-air and other GPI interfaces.
The unit was designed so that when the current analogue tape machines are no longer required, the tape changeover module can be easily removed, leaving a clean installation.
