You Need The RU-VSX4!

APPLICATION: The RU-VSX4 is the ideal choice in most applications where four video signals need to be switched
to a single output. The RU-VSX4 has two rear-panel jacks for each of the four video bridging input stages. One jack
is for the input signal; the other is a loop-through output of the source signal. If 75 Ω termination of the input signal is
required, the terminator (provided) is plugged onto the LOOP OUT jack. The output video signal is 75 Ω back­terminated to provide unity gain into a 75 Ω terminated input.

The front panel features 4 high-reliability, keyboard-style pushbuttons with LED indicators corresponding to each
video input. The LED indicators show which video source is active. If the button for an active source is pushed, all
video sources are turned off until the next source selection.

A front panel LOCAL/REMOTE toggle switch activates either the front-panel buttons or a rear-panel connected
remote control. In the REMOTE mode, the inputs are selected by an external momentary switch or open-collector
closure to ground. Five remote input terminals are provided; one for each video source, and one to shut off all video
inputs. Installing a jumper from the CTRL OFF terminal to ground permits the RU-VSX4 to be controlled by
equipment providing a continuous closure only when a source is to be switched on. In this mode, the RU-VSX4 may
be controlled by an RDL RU-SX4A Audio Switcher, an RDL RC4-RU wall-mount 4-button Remote Control, or OEM
equipment. When a video source is selected, the RU-VSX4 provides an open-collector 50 mA output to control other
equipment or modules.

When a video source is requested, either from the front panel or by remote, the RU-VSX4 waits until the next vertical
interval to switch to the requested video source. If no video is present then the switch occurs instantly. This feature
avoids the screen roll typically associated with unsynced video switchers.

Wherever a video switcher is needed to provide wide-band video source selection, local or remote control, reliability,
compactness and unsurpassed versatility, the RU-VSX4 is the ideal choice. Use the RU-RA3 rack-mount adapter to
mount multiple RU-VSX4s, or to combine related products (such as audio mixing, audio distribution, or audio
metering) into a single rack unit!
