The +ClockPlus+ is an LED SMPTE/EBU timecode display which has the added feature of changing colour from green to red when a suitable Tally input is applied. The clock face has 2.25β tall digits that display HH:MM:SS A/P in 12 hour mode or HH:MM:SS in 24 hour mode. The timecode input is taken from either VITC embedded in the video input or from LTC. When a time-code source is connected, the clock will instantly set itself to the input time. If the timecode source is removed the display will continue to update the time under control of an internal crystal oscillator.
