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 revert to previously saved position.
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 pull up/pull down buttons
&
.
In DA mode Trinity takes the incoming audio clock selected by the SOURCE knob
(3) , and puts it through the Jitter Management Module to regenerate a clean,
de-jittered signal that is distributed to the outputs on any channel that is in DA mode.
In DA mode, the outgoing sample rate will always match the incoming reference.
DA mode will not work if 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 few seconds the audio channel(s)
will revert to their last saved settings.
