The ALT-1 Adaptive Microphone Amplifier has become the preferred solution for Journalist work-stations in many European countries; most units include the remote 'TAKE' option button. Originally designed to fulfil a custom order for 10 units, orders during 2003 have resulted in over 1200 units having been sold, with Spanish broadcaster TV Catalunya taking a further 50 units to add to their existing complement, and other orders from installation companies and broadcasters in the U.K. and abroad, including 16 for Saudi Arabia.

BCD Audio's proven RMOS Express provided a custom monitoring system for the Central Transmission area of the BBC World Service. Four identical workstations are capable of monitoring 64 stereo or mono sources each, with push-button and alphanumeric display. Each workstation has comprehensive audio monitoring facilities and an interlocking system between the single main stereo loudspeakers and the local small speakers. All active electronics were packaged into two 3U crates for reliability. The control panels communicate with the racks through BCD's RS485 control system to minimise installation wiring. The unit was produced with standard BCD audio cards and a customised control surface.

Also produced for the BBC World Service was a 96 channel AES and analogue distribution system. The system is connected at the outputs of an AES router, and includes AES distribution, digital to analogue and stereo to mono conversion. Whilst all of the elements could have been provided by the Piglet range, in order to keep the rack space required below 9U a new circuit board was considered, and designed for the job.

BSkyB has been a regular BCD customer for many years, and in 2003 BCD designed and built a custom cleanfeed and IFB system for BSkyB's Millbank studios. Based on the RMOS system and previous cleanfeed systems produced for BSkyB, the requirement was realised using only two RMOS168 audio cards to achieve the talkback interruption of 16 channels of cleanfeed, and the insertion of talkback from eight different destinations. Further cards provided the gain control of these OS chains. All talkback control is achieved with 1U panels communicating back with BCD's RS485 system.

Additionally, a mono 32 into 24 router was included to route the outside sources. This was controlled by local XY control panels, and also by new BCD Audio PC software. The software communicates with the switcher via RS232 , and this PC may also communicate with up to 15 other PCs using the existing corporate network. Through this path, the router in Millbank may be controlled from BSkyB's base in Osterley Park.

An excellent example of the efficient packing density of the Piglet range was provided by an Installer-48 system for ATG Broadcast. The requirement was to interface 10 analogue VHS machines with a stereo AES router. Altogether 10 analogue to digital converter Piglets and 20 digital to analogue converter Piglets were packaged into a single 3U rack with space to spare.

The 3U Amplifier-16 system using a variety of BCD Eurocards was used to meet a requirement for 3 monitoring units for BBC Cardiff. The units provide remote VCA faders, red-light logic, and talkback facilities, thus completing all the miscellaneous facilities required to complete the Radio Studios. A similar unit is also being provided for the new BBC Mailbox studios, with additional Studio A/B switching and monitoring selection.
