Recommendations

To unleash the performance of the HD81, it is best to input video content in its original form without any processing. This will utilize the full capabilities of the HD81 for de-interlacing, scaling and image enhancement. As an example, if a user has an HDMI DVD player capable of outputting the video signal in a 480i/576i digital format, we recommend feeding it directly to the HD81 without any processing by the DVD player. This will provide the HD81 with the original digital video stream and allow the HD81 to fully unleash its studio grade video processing.

In general, we recommend the following:

If possible, use digital output (DVD, D-VHS, DTV setup box, etc). If there is no digital output, use the component output terminals (YPbPr) with short and high-quality components cables.

If you are unsure of the quality of the internal de-interlacing or scaler of your video source, let HD81 do the processing by connecting to the interlaced component output.

If possible, leave out any extra video processing in your video source (DVD, D-VHS, and HDTV STB).

Some HDTV STB models have scaling conversion that will output 1080i from a 720p format. Try to output 1080i in its native signal for- mat and let HD81 perform deinterlacing and scaling.

English

Not all HDMI DVD players have a digital interlaced output (480i/576i). For these products, it is suggested that users try 480p/576p first, followed by 720p and 1080i. After viewing the full range of out- put resolutions, the user can then judge which is the best image quality and set the HD81 for that resolution.

Many high-end analog output DVD players also come with high qual- ity DAC with 12 or 14 bits of processing.

Again, the users should try setting their 480i/576i output to HD81 first.

HD81 has BNC connectors for component video input. If the user plans to use analog component to connect to their video source, for the best image quality, it is recommend using the BNC connectors.

For connecting to Laser Disc player or S-VHS deck, we suggest to use S-video output connection to connect to HD81.

It is best to have a separate power outlet for audio and video equip- ment.
