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 VA-4H and 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.

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  
i
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).

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  
•
When exchanging a display, refresh the source by disconnecting and  
reconnecting the HDMI cable between the source and the device input
