CRD / System CRD (1963)
All-electric preset remote control (60,90,120,180,210 or 240 dimmers)
CRD was a multi-preset control for Strand's first production Controlled Rectifier Dimmers (abbreviated to CRD, later known as Thyristor) which were first perceived as only affordable by TV studios.
A 120 channel 4 preset 3 group CRD desk was built for Glyndebourne. At least 5 System CRD were installed.
