6808HDxl - Getting Started
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer 6808HDxl away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

6808HDxl - Getting Started
There are no operator serviceable parts inside the unit

before installing
2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

A maximum data rate of 3Gpbs
1 SDI input and 1 SDI output on BNC connectors
AES-3id outputs on BNC connectors
Group select DIP-switches to choose the group to de-embed
Kramer reKlocking™ & Equalization Technology that rebuilds the digital
signal to travel longer distances
Status indicators: SD/HD lock and power LEDs
5V DC power

4 Connecting the 6808HDxl
Always switch off the power to each device before connecting it to your
6808HDxl. After connecting your 6808HDxl, connect its power and
then switch on the power to each device.
To connect the 6808HDxl as illustrated in the example in Figure 3:
1. Connect an SD/HD/3G HD-SDI source (such as an HD/SD digital video
player) to the HD/SD-SDI IN BNC connector.
2. Connect the HD/SD-SDI OUT BNC connector to an SDI acceptor (such as
an SDI display).
3. Connect the AES OUTPUT A BNC connector (for channel 1) to AES digital
audio acceptor 1 (such as DAT-Recorder 1).
4. Connect the AES OUTPUT B BNC connector (for channel 2) to AES digital
audio acceptor 2 (such as DAT-Recorder 2).
5. Set the GROUP SELECT DIP-switch ON for the group to de-embed (from 1
to 4). Figure 2 shows group 1 selected.
Note: Set one switch ON only. Set all other switches OFF.
6. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).

Note: Each audio group in an SDI signal contains four mono channels, thus the
SDI stream carries a total 16 mono channels. Each AES digital signal contains two
mono channels. For example, if group 1 audio is selected for de-embedding,
output 1 contains channels 1 and 2 from group 1, and output 2 contains channels
3 and 4 from group 1.
