4 Using the VM-25 Video Distribution Amplifier
You can connect:
A single VM-25 unit (see section 4.1)
Several VM-25 units to increase the number of outputs (see section 4.2)
4.1 Connecting a VM-25 Video Distribution Amplifier
To connect the VM-25 as a 1:25 video DA
3
(see Figure 2), do the following
4
:
1. Connect a composite video source (for example, a composite video
player) to the INPUT RCA connector.
2. Connect up to 25 OUT RCA connectors
5
to the video acceptors (for
example, composite video displays).
1 Insert a screwdriver into the hole and carefully rotate it, to trim the level
2 For looping, select Hi-Z
3
DA is Distribution Amplifier
4 Switch OFF the power on each device before connecting it to your VM-25. After connecting your VM-25, switch on its
power and then switch on the power on each device
5 As required. Up to 25 outputs can be connected on the VM-25. Not all outputs need to be connected
