Chapter 2: Overview
2. Overview
2.1 Introduction
The DVI Splitters broadcast the same video with audio signals from one video (and
audio) signal source to two, four, or eight DVI compatible ports. To expand the
broadcast significantly, you can cascade several splitters together.
Depending on the length and cable quality, this fully HDCP-compliant splitter
supports DVI display resolutions of up to Full HD (1920 x 1080)/WUXGA (1920 x
1200)/UXGA (1600 x 1200), and is also Blu-ray ready. You don’t need to install
software or interface cards. Just connect the cables, power up the system and it will
duplicate video images for multiple monitors with excellent clarity. The 4- and
8-port splitters can also be rackmounted.
Use the spitters for presentations, exhibits, demonstrations, trade shows, monitor
testing and burn-in, business meetings, news, stock tickers, airline/train/bus
schedules, and retail stores.
2.2 Features
• Duplicates one video input to multiple DVI outputs.
• Saves power when signal input is lost.
• You can cascade operation for increased signal outputs.
• Provides crisp, clear, video images.
• Supports EDID, HDCP, and is Blu-ray ready for high definition display.
• Supports DVI display resolutions of up to UXGA (1600 x 1200), WUXGA (1920 x
1200), and Full HD 1080p (1920 x 1080).
• Rackmountable (AVSP-DVI1X4 and AVSP-DVI1X8 models only).
• LED indicators for signal activity monitoring
• Accurately and reliably reproduces digital video signals without attenuation and
distortion.
• Installs in seconds.

Chapter 3: Installation
3. Installation
WARNING: Before installation, power off all devices that will be connected to this
system.
• Make sure that all devices you will connect are properly grounded.
• Place cables away from fluorescent lights, air conditioners, and machines that are
likely to generate electrical noise.
Use one DVI male-to-male cable to connect a video source to the video splitter Input
(SOURCE). Connect multiple monitors or TVs to the video splitter’s output ports.
Plug a set of audio jacks from the speaker to the splitter’s audio port.
Use a DVI-to-HDMI adapter that combines digital video (DVI) and digital audio into
HDMI to seamlessly integrate into your computer systems or modern home theater.
Simply connect the optional DVI-to-HDMI adapter(s) to the output side of the
splitter, and then connect the HDMI display or projector to the HDMI output of the
DVI-to-HDMI adapter.
The adapter will convert the digital audio onto the digital video signal to generate
the HDMI signal.
Turn on your video source only after you've made all the connections.

Chapter 3: Installation
NOTE: Connect at least one monitor to the splitter before powering on the source
device.
NOTE: Connect the splitter to the computer before powering on the computer.
NOTE: Use an HDCP-compliant display to connect the splitter to the HDCP video
source.
NOTE: Each output port on the unit is required to apply the same connection
pattern whenever a DVI-to-HDMI (or HDMI-to-DVI) adapter is used for HDMI
(or DVI) signal conversion between the unit and the HDMI (or DVI) display.
Mixed (HDMI and DVI) output connections may cause signal degradation.
Signal degradation, harmful interference, or equipment malfunction are less
likely to occur if absolute connection consistency is used.
Figure 3-4. Do NOT use the mixed connection pattern shown in this diagram.
Blu-ray Ready
The splitter supports high-definition video such as DVD or Blu-ray and multichannel
audio, and carries the best signal from the source to displays; the high bandwidth
enables transmission of large amounts of information at a very high rate of speed.

Chapter 3: Installation
Blu-ray uses a blue-violet laser to read and write data, while current optical disc
technologies such as DVD, DVD±R, DVD±RW, and DVDRAM rely on a red laser to
read and write data. Blu-ray uses a blue-violet laser (405 nm) that it has a shorter
wavelength than a red laser (650 nm), which makes it possible to focus the laser
spot with even greater precision. This enables data to be packed more tightly and
stored in less space, so it’s possible to fit more data on the disc even though it’s the
same size as a CD/DVD.

Chapter 4: Operation
4. Operation
The quality of the output signal depends largely upon the quality of the video
source, cable, and display device used. Low-quality cables degrade the output signal
causing elevated noise levels. Use the proper cable and make sure the display device
is capable of handling the resolution and refresh rate selected. Interference from
nearby electrical devices can adversely affect signal quality.
