INTRODUCTION
Congratulations! You are now the proud owner of the latest generation of master clock
from the world's favourite clocking company. Based on years of research, Trinity is a
brand new design that is the most flexible, best sounding, moststable, and easiest to use
master clock available.
In one box, Trinity will save you time. Imagine! One pass with multiple frequencies and
formats of virtually any choice, all running in perfect synchronization. Well, imagine no
longer,because it's trulypossible with Trinity.
Based onAntelope's Oven Controlled Crystal Technology,Trinity has many new features
including 3 Independent Audio Generators up to 384kHz, with Varispeed control. 3
Independent SD Generators,simultaneously offering PAL and NTSC. 3 Independent HD
Generators, presenting a choice of 16 formats, and the latest revision of Antelope's
Acoustically Focused Clocking(AFC), now in it's 4 generation and employing 64 bit DSP.
th
So, that's a mind blowing 9 Independent and Simultaneous Audio/Video Generators, all
perfectly locked.
USB allowsfull remote control via PC and Mac. Firmware updates can
also be appliedvia USB if updatesare available.
The triple display shows the frequencies of the audio generators, varispeed values,
source information, pull-ups/pull-downs,and useful messages.
Temporarily lose sync from your source?... Trinity will seamlessly free-wheel until the
signal returns, andthen re-lock using thelatest Antelope `Gentle LockTechnology`.
Trinity also maintains featuresfrom the OCX-V, but in abrand new design such
; Features
as the Antelope Jitter Management Module, Black Burst Generator, Atomic Input for
connection to the 10M Rubidium Atomic Clock,and full Audio and VideoGearboxing with
simultaneous 0.1% and4% pull-ups/pull-downs.
So, please take some time toread through this manual, and familiarize yourself
reference
with the functionalitythat Trinity has to offer.
Above all, we hope you enjoyyour new Antelope as much aswe enjoyed designing
Trinity
it for you.

5.
Trinity is now providingyour chosen clock samplerate to Audio outputs A. Youcan
also use Audio channelsB and C inthe same way. It is also possible toedit all
udio channels togetherso that one frequencyis sent to all outputs on allchannels.
a
Some devices will automatically sync to clock coming from Trinity. Some will
require that you set them to external clock manually. Other devices may require
additional configuration to be able to sync to the incoming clock. Please consult
the operating manual(s)of your device(s) regardingexternal clocking.
When making initial connections, it is advised to do so with the studio volume
Note:
turned down. Some devices may emit an unpleasant sound until properly configured
to accept incoming clock.

FRONT PANEL
1. Power on/off button
2. AC/DC power indicators
Indicators to show whether AC or DC power is in use.
3. SOURCE Encoder Knob
The source knob selects the input from which Trinity receives a timing reference.
Select OVEN to use the internal oven controlled crystal oscillator, or if Trinity is
connected to the 10M Atomic Clock via the rear panel Atomic Input. The other five
source knob positions correspond to the remaining physical inputs on the back
panel input section.
If a SOURCE light flashes, the SOURCE is in a state of edit, and needs to be
confirmed by pressing the SOURCE button. If not confirmed within 10 seconds,
SOURCE will revertto previously saved position.
4. SAMPLE RATE Encoder Knob
The sample rate encoder is used to select standard frequencies, DA mode,
adjust varispeed, and confirm settings. It is used in conjunction with AUDIO
buttons (6) ,VARISPEED button , and pullup/pull down buttons & .
6
DA Mode
In DA mode Trinity takes the incoming audio clock selected by the SOURCE knob
(3) , andputs it through theJitter Management Module to regenerate a clean,
3
de-jittered signal that is distributed to the outputs on anychannel that is in DAmode.
In DA mode, the outgoing sample rate willalways match the incomingreference.
DA mode will not workif the SOURCE knob (3) is set to VIDEO or OVEN,as there is
no audio reference to distribute. In this case the display will scroll the message
“Cannot DA chosen source”. Note that in DA mode Trinity can work with
non-standard sample rates, and any sample rate in the range 27.340 kHz 449.433
kHz is acceptable.
To select DA mode for any channel, press the desired AUDIO button(s) (6),
turn SAMPLE RATE knob (4) fully clockwise , and then press the SAMPLE
RATE to confirm. If not confirmed within a fewseconds the audio channel(s)
knob
4
will revert totheir last saved settings.

5. EDIT indicator
Flashes when inedit mode, but notfor HD mode.
Note: Trinity will exit edit mode without saving if there is no user input for
10 seconds.

. AUDIO Channel Edit Select Buttons
These three buttons are used to select the audio channels for editing, and can be
edited individually or all at the same time which, if editing all can give you a big single
channel master clock utilizing all rear panel outputs. If pressed once from standard
mode the current state of the channel(s) will be visible, including varispeed and pull
ups/pull downs.
13
Note:
In edit mode, pull ups/downs are not only shown with lights & , but are also shown
12
with dashes after the frequency on the main display. So, If 0.1% & 4% pull ups are selected, the
middle and top line of the last digit on the display are lit. If 0.1% & 4% pull downs are selected,
the middle and bottom line of the last digit in the display are lit.
7. TripleDisplay
Displays information foreverything except HD.
8
. DIMMER Knob
Adjusts the brightnessof the triple display.
9
. HD Select Encoders
Use these knobs to select HD rates for the three HD channels. Press to confirm a
change.
HD1, HD2, HD3 signals are sent to the corresponding rear panel output BNC
connections .
10
. VARISPEED Select Button
35
Press this button when editing an audio channel allowing varispeed adjustment via
the SAMPLE RATE encoder knob (4). The VARISPEED button toggles between
adjustment options of cents and percent, where a 'c' on the display signifies cents
mode, and a'p' on the displaysignifies percent mode. Press SAMPLERATE
4
knob
to confirm varispeedsetting.
Once any channel has been saved with a varispeed setting, the varispeed
indicator will always light when NOT in edit mode to show that one or more
channels is usingvarispeed.
11. SPLIT Mode
This is an advanced function, and to be used only if receiving a varispeed
signal on the input. Using SPLIT will likely cause synchronization errors if
used when the input a standard gearboxing frequency. SPLIT mode disables
gearboxing for any channels that are set to DA while in SPLIT mode.
The reasoning behind this function is to avoid TRINITY mis-locking to an input
frequency that is non-standard, but very close to a standard gearboxing frequency.
(See standard gearboxing frequencies in Appendix A). If you know that your input
frequency is a non-standard, non-gearbox frequency, then use SPLIT mode to allow
DAof this non-standard input.
4
IS
For this function to have any effect, at least one audio channel must be in DA
mode. If no audio channels are in DA mode, and SPLIT is activated, the input
will be ignored. When SPLIT is activated, the audio channel(s) that is/are set to
DA will lock to the SOURCE signal. All channels not in DA mode will
NOT
continue to generate the frequency displayed for the respective channel(s), and
will be running on internal oven or external Atomic.
Note:
The SPLIT button has no function when SOURCE is set to VIDEO or OVEN.

display for the given channel(s), the top line of the digit to the far right is lit for a pull
up, and thebottom line is litfor a pull down.
Notes:
If 0.1% & 4% pull ups are selected, the middle and top line of the lastdigit on the display are lit.
If 0.1% & 4% pull downs are selected, the middle and bottom line of the last digit in the display
are lit.
13. European pull up/pull down (+/- 4%)
When in edit mode, this button toggles +/- 4% pull up/pull down for the channel(s)
being edited. To confirm an edit press the SAMPLE RATE knob (4). On the triple
4
display for the given channel(s), the top line of the digit to the far right is lit for a pull
up, and thebottom line is litfor a pull down.
Notes:
If 0.1% & 4% pull ups are selected, the middle and top line of the lastdigit on the display are lit.
If 0.1% & 4% pull downs are selected, the middle and bottom line of the last digit in the display
are lit.
14. Status LEDs

The S/PDIF input is an RCA connection that accepts S/PDIF clock or audio.
The video input is a BNC connection that accepts video reference. See appendix
on page 11
B for supported formats.
The BNC Atomic Input connection allows Trinity to receive a 10MHz reference from
an atomic clock device, such as the Antelope 10M. When locked to Atomic, the
internal oven on Trinity is automatically bypassed, the front panel ATOMIC LED
lights, andthe atomic device becomes the primary timing reference. This effectively
provides 8 day sample accuracy, which means even more detailed sound and
greater stability.
The sample rate on these outputs always matches the sample rate indicated by the
frequency display forchannelAon the front panel.
