ADX-1842/1852
USER PRESET menu
LOAD:
Selects which predefined parameter settings will be
used by loading a personalized user profile.
SAVE
: Saves the parameter settings in one of the five
possible user preset profiles.
AES OUTPUT menu
AES OUT 1-2 and AES OUT 3-4:
Selects which
embedded audio group will appear at the indicated AES
outputs of the ADX-1842 or ADX-1852.
AES OUT 1, 2, 3, 4
:
MUTE
;
SWAP L&R
: Select ON or
OFF for each of the four AES outputs to mute the output or
swap the left and right signals.
LEVEL
: Sets the audio gain
from -96 dB to +12 dB in 0,5 dB steps.
PHASE INVERT
:
Select “on”, to invert the selected audio channel phase.
AES DELAY
: Sets the delay of the AES audio as it passes
through the disembedder. Selectable between NONE, and
a number of video frames (0 to 3 frames in ½ frame steps).
CONFIG LTC menu
FROM:
Allows the user to select the source of the time
code appearing at the LTC output as translated from either
the first or second embedded ATC (HD input only).
DVITC LINE:
Selects the video line from which the DVITC
is extracted. The extracted DVITC is then translated to LTC
(SD input only).
DELAY:
Sets the time code delay when the extracted time
code is translated to LTC. The delay is selectable between
NONE and a number of video frames (1 to 3).
MONITOR OUT menu (ADX-1852 only)
SOURCE:
Selects AES OUT 1, 2, 3, or 4 for stereo analog
audio conversion.
LEVEL 0dBFS:
the output level is adjustable in 1 dB steps
for an output level of +12 dBU to +24 dBU at full scale
amplitude.
VBIT:
Selects the action if the AES channel status V-Bit is
set. Select MUTE to mute the analog audio output or
PASS to disregard the V-Bit status.
CONFIG TEST menu
AES 1, 2, 3, 4:
the user can enable or disable a test tone
(1 KHz, R-steady, L-pulsed, at –18dBFS) on each of the
four AES outputs individually.
LTC OUT: User can enable a LTC test loop (10 seconds
loop starting at 23:59:00:00).
CONFIG ALARM menu
The user can configure the status LED presentation
(ALARM LEVEL) and fault reporting (NONE or GPI) for
some of the fault conditions of the ADX-1842 or ADX-1852.
NO SIGNAL:
the errors include, no HD/SD-SDI signal
attached to the card input, or faulty incoming HD/SD-SDI
signal.
NO LTC:
Indicates that there is no embedded time code
data in the HD/SD-SDI signal.
NO AES 1-2 and NO AES 3-4:
Indicates that the selected
audio group for the AES outputs is not present in the
HD/SD-SDI signal.
TEST MODE:
Indicates whether test signals are present
on any of the ADX-1842 or ADX-1852 audio outputs or
LTC outputs.
FACTORY DEFAULT menu
Select
RESTORE
to reset all of the menu-adjustable
parameters to a factory-preset state (indicated in the menu
by an underline in the list of available choices).
