BEFORE YOU BEGIN

For over a decade, Antelope's legendary OCX Master Clock has been a dominant force in the audio world. This legacy now continues with the newest master clock by Antelope Audio - Isochrone OCX HD.

OCX HD raises the bar yet again, delivering sample rate support of up to 768 kHz, Antelope's best-in-class 4th generation Acoustically Focused Clocking (AFC) jitter management algorithm and oven-controlled crystal oscillator.

OCX HD Master Clock offers a great variety of clocking options – 10 configurable in pairs. Word Clock outputs on BNC, four AES/EBU outputs and two more on S/PDIF. This vast assortment of connectivity make the OCX HD the most versatile audio master clock on the market. Our proven advanced proprietary clocking technology delivers the most musical and reliable audio sync generation.

Additionally, OCX HD offers two word clock inputs and a video sync input, which can resolve to a huge variety of SD and HD formats, as well as clock distribution with gearboxing, and pull-up and pull-down rates, as featured in the triple clock powerhouse, Trinity Master Clock. A 10 MHz input allows for syncing with Antelope's newest atomic clock – 10MX.

Antelope's newest master clock benefits a user-friendly software control panel, available for both macOS and Windows. The desktop app provides convenient remote control to simplify project workflow. The device is also easily configurable from an elegant front panel, which adds futuristic appeal to any gear rack.

Enjoy working with the OCX HD!

Best wishes,

Team Antelope

FRONT PANEL EXPLAINED

Power Switch

Toggles standby / operation state. When the device is powered on, an illuminated ring will glow around the power button.

Oven Clock Light

When lit, this indicates OCX HD is clocked by its internal oven-controlled crystal oscillator.

LOCK Indicator

When lit, this indicates OCX HD is locked to a signal that enters through the WC, Video, S/PDIF or AES/EBU inputs.

Atomic LOCK Indicator

When lit, this indicates OCX HD is locked to an atomic signal that enters through the 10M input on the rear panel. This overrides the Oven Clock lock light as soon as it is plugged in and the Oven Clock lock light will automatically go off.

Clock Source Selection Knob

This selector allows you to select the current Clock Source for the OCX HD. 'Oven' is for the internal clock, the rest of the options are for clocking to an external source.

Sample Rate Indicator

Indicates the current sample rate of the master clock. When using DA mode, the indicator blinks if no source is present.

Sample Rate Selection Knob

This selector lets you increase and decrease the sample rate, choosing from 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz, 705.6kHz, 768kHz. The current frequency is indicated on the display when adjusting. To confirm, simply press the selector knob.

When clocked to an external source: Press and hold the knob for 2 seconds to fetch the current source's sample rate and set it.

European pull up / pull down (+/- 4%)

This button toggles +/- 4% pull ups / pull downs

USA pull up / pull down (+/- 0/1%)

This button toggles +/- 0.1% pull ups / pull down

Presets

Three Preset buttons store and recall your 'favorite' set-ups. Press and hold the button for 2 seconds to store a preset. Press to recall.

Calibration Mode Explained

Ensure atomic signal is fed to the Atomic Input, Atomic Clock is locked and the OCX HD Atomic Clock Indicator is lit. Press both Source Selection and Sample Rate Selection knobs simultaneously. The device will enter calibration mode.

The Sample Rate indicator will show a number which will stabilize with time. Wait for the number to become stable. This number represents the error of the OCX HD's clock related to the Atomic Clock.

To compensate for this error, press the Sample Rate Selection knob. Repeat the procedure as many times as necessary so that the number becomes as close as possible to Zero and relatively stable (number may have small deviations in a few seconds).

To exit this mode, press the Standby button.

REAR PANEL EXPLAINED

AC Power Connection

This IEC connection supports inputs of 100 – 240 V\~ to automatically accommodate mains voltages in any country.

Word Clock Inputs

BNC Connectors used to accept World Clock reference.

Video Input

BNC Connector used to accept Video reference. When active the OCX HD will lock to the sample rate of the incoming video signal.

10M Atomic Clock Input

This BNC Input Connector allows the OCX HD to receive timing reference from an Atomic Clock, such as the Antelope 10M and 10MX, to increase the Oscillator accuracy.

If the device is in Oven mode, plugging in the atomic clock causes the “Atomic LED” light to illuminate on the device front panel and the atomic device becomes the primary timing reference.

S/PDIF Inputs

These two inputs can receive S/PDIF clocking reference up to 192 kHz.

AES/EBU Input

This input can receive AES/EBU clocking reference up to 192kHz.

Word Clock Outputs

Ten Word Clock Outputs on BNC connectors.

AES/EBU Outputs

These four outputs provide AES/EBU clock at sample rates up to 192kHz. Note that if the OCX HD is working at a higher sample rate than the receiving device, the Word Clock signal cannot be output via this AES/EBU connector.

S/PDIF Outputs

These four outputs provide AES/EBU clock at sample rates up to 192kHz. Note that if the OCX HD is working at a higher sample rate, the Word Clock signal cannot be output via this S/PDIF connector.

USB Type B Connector

Allows connection to PC and Mac for the Control Panel application and firmware updates.

CONTROL PANEL

The PC/Mac Control Panel application is organized into these sections and offers the following functionality:

1. Function Strip

From left to right:

On/Standby button

Powers the OCX HD on and off.

Device S/N

Shows which device is currently controlled. If you have multiple devices connected to your PC/MAC computer (or different computers wired in the same Local Area Network), you can select which one to control.

Calibration Mode

Opens the calibration panel:

To calibrate an Atomic Master Clock, ensure atomic signal is fed to the OCX HD's Atomic Input, the Atomic Clock is warmed up and the OCX HD Atomic Clock Indicator is lit.

1. Click 'Calibration' and the device will enter calibration mode

2. The indicator below will show a number which will stabilize with time. Wait for the number to become stable. This number represents the error of the OCX HD's clock related to the Atomic Clock. To compensate for this error, click the 'Calibrate' button.

1. Repeat the procedure as many times as necessary so that the number becomes as close as possible to 0 and relatively stable (it may have small deviations of a few seconds). To exit Calibration Mode, press the X button.

Panel lock indicator

You can lock or unlock the Control Panel by clicking on the Pad Lock symbol. When the Control Panel is locked, the device will not accept commands from its front panel interface and/or the application, thus preventing accidental changes during sessions or live events.

Info button

Displays Control Panel version, hardware version, device serial number, and firmware version. You can also launch the Firmware Update wizard to check for and initiate firmware updates.

2. Clock indicators

- Oven - When lit, this indicates OCX HD is clocked by its internal oven-controlled crystal oscillator.

- Atomic - When lit, this indicates OCX HD is locked to an atomic signal that enters through the

10M input on the rear panel. This overrides the Oven Clock lock light as soon as it is plugged in and the Oven Clock lock light will automatically go off.

- Lock - When lit, this indicates OCX HD is locked to a signal that enters through the WC, Video, S/PDIF or AES/EBU inputs.

3. Clock Sources

Choose between the available clock and sample rate sources from the drop-down menus.

4. Pull up/pull down controls

Adjusts the Word Clock sample rate to sync to PAL/NTSC video.

5. Brightness slider

Adjusts the device's screen brightness from 0 to 100%.

6. Clock Source Out

Indicates the output sample rate. This might change if the sample rate is affected by pull ups / pull downs.

7. Multipliers

5 dropdown menus used to multiply or divide the current selected sample rate on pairs of 2 Word Clock outputs. This way, the OCX HD can output up to 5 different sample rates on each pair of 2 Word Clock outs. That is, if the sample rate is 96kHz , dividing it by two makes 48kHz and multiplying it by for 4 makes 384kHz .

8. Presets

Three preset buttons to store your favorite set-ups. Single click recalls the desired preset. Holding Ctrl on Windows or Command on MAC and clicking saves the current set-up.
