Step 4: Connect the inputs and outputs
Each VS-8UFX port can be defined as an input or an output, enabling flexible configurations such as 1x7 distribution amplifiers, 7x1
routers or any other possible input-output combination. By default, the VS-8UFX is set to operate as a 4x4 router: PORT 1 to PORT
4 as the inputs and PORT 5 to PORT 8 as the outputs.
Always switch OFF the power on each device before connecting it to your VS-8UFX. For best results, we recommend that you
always use Kramer high-performance cables to connect AV equipment to the VS-8UFX.
Optionally, daisy-chain the VS-8UFX by looping the genlock source to the next machine.

There are no operator serviceable parts inside the unit.
Use only the power cord that is supplied with the unit.
Do not open the unit. High voltages can cause electrical shock! Servicing by qualified personnel only.
Disconnect the power and unplug the unit from the wall before installing.
