21 Troubleshooting
In this chapter you will find some solutions to some of the more common situations
and issues you may come across.
Observation
Corrective action
I have connected a video source
to the Lecture Recorder x2’s DVI
In or S-Video ports but I am not
sure whether the connected
source is being received from the
incoming ports
For the DVI In port:
1. Connect a DVI or VGA monitor to a
Lecture Recorder x2’s DVI Out port (use
DVI-VGA adapter if necessary) and view
the stream on the monitor.
For the S-Video port:
1. Unplug a cable from a DVI In port (if
any).
2. Ensure that the video channel is
enabled on the Stream Setup page in
Web Admin Interface.
3. Look at the red LED. If it is blinking, the
signal is being received from the S-
Video port.
No sound is coming from an
audio source
Verify the Input Source parameter value in the
Audio menu item of the web interface. It should
correspond to the selected source type (Line or
Microphone).
Too much noise on audio
Verify the Input Amplifier Volume parameter
value in the Audio menu item of the web
interface. It is recommended to select 40% in
this field.
Insufficient image quality
To provide better productivity and higher image
quality:
1. Make sure that the source resolution
matches the resolution of the
recorded image. Ensure that the
Frame size parameter value in the
Stream Setup menu item of the web
interface equals the frame size of the
source image.
Example: If the source video resolution is 720p,
set the Frame size to 1280x720
