Audio Delay

From firmware version 3.80 onwards, the SE-
2800 and HS-2800 switchers now have a feature
for Audio Delay up to 16 fields, or 8 frames. The
audio delay is expressed in fields with a default
setting of '02' (2 fields / 1 frame) on each input
until you change it.
First you will need to confirm the firmware version
number for your switcher.
1. Power on 2800 Switcher.
2. Press any arrow key under the designated
Menu row.
3. Press the Right Arrow [►] key to check your
Version Number.
With your firmware updated to 3.80 or later, you
can now follow the next steps to set up your Audio
Delay.

Setting the Audio Delay

1. Power on 2800 Switcher.
2. On the Preview bus, select the input that you
would like to set Audio Delay.

GPI / GPO Connections

The SE-2800 can control external recorder/
playback devices like the HDR-45 and HDR-55
via a simple contact closure GPI / GPO switch.
The GPI interface is a 3.5mm Jack Socket
which is situated on the rear panel of the SE-
2800. Contact closure between the Outer and
Inner contacts on the jack plug will trigger a user
selected event. Power is supplied by the SE-2800
and is less than 5V DC.
3.5mm Stereo Jack Plug
Contact closure between inner and cuter
will send a GPI Trigger

Audio Settings" is selected.
5. Press the Right Arrow [►] key to enter into
the Input Audio Settings Menu.
6. Press the Right Arrow [►] key to enter the
Audio Delay Setting Menu.
The default setting is 02; which is measured in
fields. 2 fields = 1 frame.
7. Use the Arrow keys to set the number of fields,
or frames. You can set the delay from 1 to 16
fields, which is the equivalent of 1 to 8 frames.
8. When you have made your selection, press
the Enter key
9. To Exit the Menu, press any key in the
Program or Preview Bus.
* To set audio delay for all inputs: repeat the
above steps for each individual input. Otherwise,
the Audio Delay will remain at the default setting
of 02.
This GPI socket can also be used as a GPO
socket to trigger record or playback events with
other equipment such as the Datavideo HDR-70
recorder.
SAFETY FIRST The cabling required needs to
be designed specifically to connect the SE-2800
to the chosen record or playback device as they
are not all the same. The cabling required can
be made by yourself or a competent technician.
Please speak with your Dealer or local Datavideo
office to get further help and advice.
