Antelope Audio Isochrone Trinity 384 kHz HD Master Clock

The Antelope Audio Isochrone Trinity is a top-tier 2U master clock that brings unparalleled precision and stability to professional studios and post-production environments. It combines an oven-controlled crystal oscillator with 4th-generation Acoustically Focused Clocking (AFC) powered by 64-bit DSP, delivering ultra-low jitter and pristine audio fidelity across all digital workflows.

Capable of generating up to 384 kHz sample rates with nine independent generators (audio, HD video, and SD video), Trinity offers extensive connectivity—including universal video, word clock, atomic clock, AES/EBU, and S/PDIF I/O. A dual-redundant power supply ensures continuous operation, making it a reliable centerpiece for demanding setups.

Key Features

• 4th-Gen AFC with 64-Bit DSP: Oven-controlled timing ensures exceptional clock stability and sonic clarity.
• 9 Independent Generators: Supports 3 audio, 3 HD video, and 3 SD video clock outputs, all simultaneously.
• Atomic & AFC Sync: Sync via atomic input or internal oscillator with calibration accuracy better than ±0.001 ppm and aging under 1 ppm/year.
• 384 kHz Support: Generates high-resolution clock outputs with varispeed adjustment up to ±200 cents and pull-up/down options for NTSC/PAL formats.
• Robust Connectivity: Includes universal video input, dual word clock BNC inputs, AES/EBU, S/PDIF, and USB for control and firmware updates.
