Video Connections
The UMT has a range of applications. If your only use is the playing of audio discs, then no video connection is required. The system
setup is optimum for you and all you have to do is make the proper audio connections. If your interests is in playing music from a Hard
Disc, USB stick or from a computer network, then a video display is needed for navigation. A small computer monitor with no audio
and an HDMI input would be ideal. If you plan to watch DVDs or Blu-Ray discs then the UMT will need to be connected to your video
display or projector.
Method 1 – HDMI Connection Directly to a Display
If your Display has an HDMI (High-Definition Multimedia Interface) input, you can use the
included HDMI cable to connect the player to the Display. This connection method delivers
both video and audio in a digital format via a single cable. The HDMI video output of the
player allows for the highest possible video quality and resolution. The audio is of low quality
and should NOT be used.
There are two HDMI output terminals (HDMI 1 and HDMI 2) on the rear panel of UMT, both
of which can be connected to your Display. We recommend to use HDMI 1 since it benefits
from the dedicated Marvell DEO video processor, and set the “Primary Output” option in the
setup menu to “HDMI 1” (below). This output should also be set to “Video Only”.
You may connect the composite video cable to a TV for troubleshooting purposes, or if only
menu navigation is desired, because it only produces a standard definition video signal and forfeits the advantage of high definition video.
Method 2 – DVI Connection to a Display
If your display has a DVI input that supports HDCP, you can purchase an HDMI-
DVI adapter cable to connect the player to the display. This connection method
delivers digital video to the display without any signal degradation. The HDMI
video output of the UMT presents the highest possible video quality and resolution.
We recommend to use HDMI 1 since it can benefit from the dedicated video
processor, and set the “Primary Output” option in the setup menu to “HDMI 1”
(please see more details below).
Video Settings
Primary Output: To select the primary video output port. The options are:
• HDMI 1 – Use HDMI 1 as the primary video output port. This setting will ensure that the HDMI 1 output gets the best possible
picture quality. The dedicated QDEO DE2750 video processor will be used unless “Source Direct” for output resolution is selected,
in which case QDEO DE2750 video processor is bypassed. Component and composite video output may not be available or may be
limited to a lower resolution based on content source limitations.
• HDMI 2 – Use HDMI 2 as the primary video output port. Similar to “HDMI 1”, this setting ensures that the HDMI 2 output gets
the best possible picture quality, except that it utilizes the video decoder in the player to perform necessary video processing, not the
DE2750 video processor.
Audio Connection
Audio on HDMI
Although the UMT can output audio over HDMI, this audio will not benefit from the MSB processing and its use is not recommended.
We set the HDMI Audio output to “OFF”.
Audio Ground Noise
Today we are on a new frontier of performance with new multi-media sources loaded with electrical noise unlike anything we ever
experienced in the past. At the same time we have made great improvements in jitter, the enemy of the last decade, making ground noise
which used to be lost in the jitter, the dominant problem. And again, grounding issues are back, making a huge difference, but now in
harshness, focus, detail and air, instead of hum.
There is no intuition, right or wrong with high frequency ground noise. When all we had to deal with was 60 Hz AC hum, the concept
was easy to visualize. Get rid of ground loops. But now we are fighting a new animal. We have had some idea about ground noise, but our
experience has shown just how tricky it is. It all started for me with the question of why the sound changed when I changed my digital
cable? The DAC reclocks and all the bits arrive correctly in memory. What is different? Ground noise. Now as we do network streaming
and have a Blu-ray player hooked up to an LCD monitor as a source, the matrix becomes impossible to deal with anyway but the old
way. Try making changes and listen.
