7.2 TCO-HDSP
After installation of the TCO-HDSP update to the latest driver and firmware version, found on
the website
www.rme-audio.com
in the section Download.
After reboot the Settings dialog includes an additional page TCO, and on the main page the
new sync-option TCO can be selected.
For synchronization to a video or LTC signal choose
Clock Mode
AutoSync and TCO as
Pre-
ferred Sync Ref
on the main page of the settings dialog. All further settings are done on the
TCO page.
LTC In:
The time values read from the LTC signal. These values are passed unchanged to the
application.
Input State:
An LTC input signal detection as valid (valid) is followed by the display of the num-
ber of frames per second, and whether this is Full Frame or Drop Frame code. A valid video
signal is shown as PAL or NTSC. An incoming word clock signal is analyzed and displayed to
be in the Single Speed, Double Speed or Quad Speed range.
Sync Source:
Input select switch for the
inputs LTC, video and word clock.
Lock
is
displayed as soon as the TCO is able to
synchronize on an input signal. Also at the
bracket the green LED will light up.
Video / Word Input:
The BNC input can be
terminated with 75 Ohms. At the bracket the
yellow LED will light up.
WCK Conversion:
Default setting is 1:1.
This very special option allows for a
synchronous conversion of the word clock
input signal. 44.1 kHz will turn into 48 kHz,
where the 48 kHz are not free running, but
have a synchronous relationship to the
original clock. The same is available for
converting 48 kHz to 44.1 kHz.
Frame Rate:
The frame rate of the incoming
SMPTE signal must always be defined
manually.
Sample Rate:
The TCO derives a word clock
of 44.1 kHz or 48 kHz from the sync-signal.
With the setting 'from App' the value sent
from the ASIO application to the driver is
used.
The lower field provides common Pull-Up and Pull-Down values. The final value of the previ-
ously defined sample rate is shown in the field
Frequency
in case the sync-signal is valid.
Frequency:
The TCO measures the word clock that it generates and shows the current value in
this field.
Note: The MTC signal is provided via a new (virtual) MIDI input port. This one has to be chosen
as MTC sync source in the application.
