2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality
•Position your Kramer VA-4H away from moisture, excessive sunlight and
dust

•A maximum input resolution of 1080p
•HDTV compatibility
•Compliance with standards: HDMI and HDCP 1.2
•Support of HDMI (V.1.4 with Deep Color, x.v.Color™, Lip Sync, HDMI
Uncompressed Audio Channels, Dolby TrueHD, DTS-HD, CEC)
•Four input/output channels
•Four tamper-proof, recessed selector pushbuttons
•Non-volatile memory that saves final settings

4 VA-4H - Overview
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
audio/video interface, widely supported in the entertainment and home cinema
industry. HDMI ensures an all-digital rendering of video without the losses associated
with analog interfaces and their unnecessary digital-to-analog conversions. It delivers
the maximum high-definition image and sound quality in use today. Note that Kramer
Electronics Limited is an HDMI Adopter and an HDCP Licensee.
HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered
trademarks of HDMI licensing LLC.
In particular, HDMI:
•Provides a simple interface between any audio/video source, such as a set-top
box, DVD player, or A/V receiver and video monitor, such as a digital flat
LCD / plasma television (DTV), over a single lengthy cable
SIMPLICITY - With video and multi-channel audio combined into a single cable, the
cost, complexity, and confusion of multiple cables currently used in A/V systems is
reduced
LENGTHY CABLE - HDMI technology has been designed to use standard copper cable
construction at up to 15m
•Supports standard, enhanced, high-definition video, and multi-channel digital
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - HDMI supports multiple audio formats, from
standard stereo to multi-channel surround-sound. HDMI has the capacity to support
Dolby 5.1 audio and high-resolution audio formats
•Transmits all ATSC HDTV standards and supports 8-channel digital audio, with
bandwidth to spare to accommodate future enhancements and requirements
•Benefits consumers by providing superior, uncompressed digital video quality
via a single cable, and user-friendly connector
HDMI provides the quality and functionality of a digital interface while also supporting
uncompressed video formats in a simple, cost-effective manner
•Is backward-compatible with DVI (Digital Visual Interface)
•Supports CEC, two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
•Has the capacity to support existing high-definition video formats (720p, 1080i,
and 1080p, 2K and 4K), standard definition formats such as NTSC or PAL, as
well as 480p and 576p

VA-4H - Overview 5
3.2 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel, protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.
3.3 Defining EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the VA-4H to “know” what kind of monitor is
connected to the output. The EDID includes the manufacturer’s name, the product
type, the timing data supported by the display, the display size, luminance data
and (for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).

8 VA-4H - Connecting the VA-4H
5 Connecting the VA-4H
Always switch off the power to each device before connecting it to your
VA-4H. After connecting your VA-4H, connect its power and then
switch on the power to each device.
To connect the VA-4H as illustrated in the example in Figure 3:
1. Connect up to four HDMI sources (as an example, DVD players) to the
HDMI IN connectors.
2. Connect the HDMI OUT connectors to up to four HDMI acceptors (as an
example, displays with speakers).

6 Operating the VA-4H
To set the EDID source for each channel as illustrated in the example in Figure 3:
1. Press and hold the CAPTURE pushbutton. The indicator LEDS illuminate in
a cycle as follows:
MONITOR, lower green LED
DEFAULT, upper red LED
PASS, both LEDS together.
2. Release the pushbutton at the desired setting.
The setting is saved in non-volatile memory.
Notes:
•DEFAULT and MONITOR settings do not support HDCP key exchange.
For the display to work properly with HDCP encryption, the VA-4H must be
set to PASS
•If an EDID is captured the MONITOR LED flashes slowly
•If an EDID is not captured, the DEFAULT LED flashes quickly and the
default EDID is loaded
