THE DEVIL'S HIGHWAY

MORTIMER WEST END

READING, BERKS RG7 2AD

Shown here are some aspects of just a few of the many AV Systems for which we have carried out the roles of electronic designers and installers. For a full list of installations see the "Installations" pages of the "Services" section.

STANDARD CHARTERED BANK, BISHOPSGATE.

Boardroom AV system

for JMC Compak; 1985.

This rear projection system had Slide, Overhead, Cine and Video projectors. The image from the selected source was aligned with the screen by servo controlled mirrors. It also boasted Prestel (a defunct BT Information service).

OXFORD STADIUM

Video Display System for Advanced Totes; 1999.

This system has approximately 80 monitors distributed about the stadium. The ones shown here are in the restaurant. Generally the monitors are in groups of six in two back to back sets of three. In each set, two show various Tote odds and the third shows live or recorded video of the races.

Mains power to the monitors is controlled by low level commands carried with the video signals. To avoid large switch-on surges, each block of six monitors automatically powers up in sequence when the Tote System is switched on.

CD LISTENING POINT

for ASV, 1996

These systems were installed in some Woolworths stores as part of a high-tech AV and PC initiative.

The unit was activated when the user lifted the headphones from the rest and the LED displays flashed to prompt the selection of a disc and track number. The Listening Point was connected to a central multi-CD player by a small ribbon cable which conveyed power, plus audio and control signals. After the user selection, the listening point microprocessor generated the appropriate serial stream to command the CD player. When the headphones were returned to the rest the CD player was commanded to stop and volume was normalised.
