Antelope Audio Isochrone Trinity Universal HD Master Clock

Antelope Audio Isochrone Trinity: Universal HD Master Clock for Large Facilities

The Antelope Audio Isochrone Trinity is a universal high-definition master clock that combines three independent audio generators, full professional video sync, and dual redundant power in a single 1U (1.75-inch) rack unit. Built on the fourth-generation 64-bit clocking engine, it can drive many converters and consoles at once while locking to or generating every known professional SD and HD video format. Its menu-free front panel and triple display make a complex distribution system fast to read and instant to adjust. For a large studio, broadcast plant, or scoring stage that needs one authoritative house clock it can rely on around the clock, the Trinity is that reference.

Three Independent 384 kHz Audio Generators

The Trinity contains three fully independent audio clock generators, each capable of running simultaneously at rates up to 384 kHz. Independent generators mean the clock can supply three different sample rates to three different device groups at the same instant, all derived from the same master oscillator. In a facility where a tracking room, a mix room, and a transfer bay all draw from one house clock, this lets each work at its own rate without contention. That single-box flexibility is what large rooms need to keep every converter locked to a common, trusted source.

Varispeed: +/-200 Cents of Musical Pitch Control

Each generator offers varispeed adjustment across a range of +/-200 cents, letting you deliberately shift the clock rate to raise or lower playback pitch and speed. Because a converter's pitch follows its clock, nudging the master frequency is a clean, whole-system way to change the pitch of everything referenced to it at once. Engineers use this to match a performance to a different key, to create classic tape-style speed effects, or to conform material recorded at a slightly different rate. Having varispeed built into the house clock means the whole facility can shift together with a single adjustment.

Universal Video Sync: Every Known Pro SD and HD Format

The Trinity locks to and generates all known professional standard-definition and high-definition video formats, with three HD and two SD generators on board. A video reference is the shared timeline a picture facility runs on, and resolving to it keeps audio frame-accurate against the edit through record and playback. Because the Trinity both reads an incoming video reference and generates its own, it can slave to an existing plant or become the master that everything else follows. For multi-format post and broadcast work, that universal coverage removes the format-compatibility guessing that stalls a session.

Comprehensive Word Clock Distribution

The Trinity provides an extensive set of BNC word clock outputs with two user-selectable rates spanning 32 kHz to 384 kHz, sized for large converter and console setups. Word clock is the sample-level pulse that tells each device exactly when to capture or reproduce a sample, and driving many outputs from one master keeps an entire rack sampling in perfect lockstep. Offering two selectable rates at once lets different device banks run different formats without a second clock or external converter. In a big facility this is the practical core of the Trinity's job: one master, many perfectly aligned devices.

Dual Redundant Power Supply for Mission-Critical Uptime

The Trinity runs on a dual redundant power supply, so a second internal supply immediately carries the load if the primary ever fails. In a house-clock role the timing reference is the single point every device depends on, which means its reliability defines the reliability of the whole facility. Redundant power removes that single point of failure, keeping the clock alive through a supply fault without dropping sync mid-session. For a broadcast plant, mastering suite, or scoring stage where downtime is unacceptable, this is the feature that lets an engineer trust the Trinity as the backbone of the room.

10M Atomic Input: Reference to an Atomic Source

A 10M BNC input lets the Trinity accept an external 10 MHz atomic reference, such as the signal from the Antelope Audio 10MX. Disciplining the Trinity's oscillator to a rubidium-grade 10 MHz source upgrades the accuracy of the entire distribution network to atomic-grade stability. This gives a facility a clear path to grow: run the Trinity as the house clock now, then add an atomic reference later without changing the rest of the system. Once paired, every converter downstream inherits the same ultra-stable timing from a single physics-grade heartbeat.

Menu-Free Front Panel with 64-bit AFC Clocking

The Trinity presents a menu-free front panel with a triple display and runs on Antelope Audio's fourth-generation 64-bit Acoustically Focused Clocking driving an ultra-stable oven-controlled oscillator. The menu-free layout means every important parameter is a single button or knob away rather than buried in software pages, which matters when a fast-moving session needs an instant change. Underneath, the AFC engine continuously corrects jitter while the oven-controlled crystal holds the reference steady against temperature swings, preserving accuracy across long days and years of service. The engineer gets both immediate tactile control and the deep timing stability that tightens transients and stabilizes imaging.
