Powered by an ultra stable oven controlled crystal oscillator, Trinity’s completely redesigned timing
engine with 4th generation 64-bit Acoustically Focused Clocking provides supremely low jitter and high
stability, with distinct sonic advantages that are immediately apparent.
An atomic input makes it a perfect match for the 10M Atomic Clock, while user re-calibration and dual
redundant power supply will keep the unit running smoothly and prevent costly downtime.
Trinity takes care of requirements that usually would have needed several units. With 3 HD and 2 SD
generators the unit locks to and generates all known professional video format, while simultaneously
offering 3 independent audio channels capable of 384 kHz with varispeed adjustment in cents or percent!
With its wealth of connectivity, flexibility, and ease of use, Trinity is the ideal linchpin for a modern
