Antelope Audio Trinity

Antelope Audio Trinity Master Clock

The Trinity is a professional master clock that installs seamlessly into any standard 19-inch rack, its compact 3.5-inch height making efficient use of valuable studio real estate. This unit sits at the heart of world-class recording facilities, live sound systems, and post-production suites globally, delivering the timing precision that separates clean, locked recordings from unstable ones. The intuitive front panel with triple display eliminates menu diving, letting you manage nine simultaneous generators with immediate feedback.

Clocking Architecture & Stability

Built around 4th Generation Acoustically Focused Clocking with 64-bit DDS, the Trinity achieves stability better than ±0.02 ppm at 65°C and calibration accuracy to ±0.001 ppm—performance that becomes audibly apparent in the reduced jitter and phase coherence across your entire signal chain. The oven-controlled crystal oscillator maintains rock-solid timing, while the optional atomic clock input (10 MHz @ 1Vpp on BNC) allows field recalibration to atomic standards for facilities requiring absolute precision.

Audio & Video Generation Capacity

The Trinity generates three independent audio channels capable of 384 kHz with varispeed adjustment (±200 cents, +12.246% / -10.910%), alongside three dedicated HD and three SD video generators that simultaneously support all known professional video formats—NTSC, PAL, and 16 HD variants. This eliminates the need for separate sync boxes, consolidating your entire timing infrastructure into a single unit with dual redundant power supply for uninterrupted operation.
