27 Mbytes/ s Parallel Interface Regenerator. This unit is
required to extend the transmission distance of the
27 Mbytes/s bytes/s EBU parallel interface for digital
video signals. It amplifies the received video and clock
signals and a phase locked loop is used to regenerate the
clock signal. This is used to retime the video data
signals before they are transmitted with the regenerated
clock. Basic alarm facilities which monitor the status of
the input data signals, clock and power supplies have bee

Dual Loudspeaker Amplifier. First developed for Outside
Broadcast communications in television. Each amplifier has
available for use with an unbalanced signal matrix. The
gain of each amplifier and overall 'high normal cut'
volumes are remotely controlled. A band pass filter can be
switched into circuit by a front panel control which
reduces any incoming LF or HF noise. This can be
overridden remotely. Monitoring push buttons connect each
output to a buffered bus bar. The bus bar can be connected
to other units and to a signal monitoring system. Power
requirements ~16V 160mA quiescent. 100mm x 220mm Eurocard.
Mounted on 0.6" width front panel for 3U high racking with
96 way Euro-connector. Supersedes AM5/18. SCPD 1983.
Loudspeaker Amplifier. General purpose loudspeaker
amplifier designed as a replacement for the AM8/12. It
uses a Quad 405 amplifier circuit board and has similar
