CONNECTING TO VIDEO DEVICES
Video sources and output devices (such as monitors, projectors or recorders) may be
connected to the amplifiers through the BNC type connectors located on the back of the
units. Unused inputs are terminated to 75 , and active inputs should be terminated at the
connecting source. Please keep in mind that the output signal format will match that of the
input signal format. (Example: If input is composite, then output is composite.) All signal
connections that use more than one cable interconnecting between devices should be of
equal length. (Example: R,G,B cables between a camera and the amplifier should be equal
in length.) The signals supported by the various models are described in Table 12.

USING THE VIDEO AMPLIFIERS
Powering On The Amplifier
NOTES
1. The amplifier should only be powered on, after all connections are
completed, and all source devices have been powered on. Do not
attempt to connect or disconnect any video, audio or control
signals to the amplifier while it is powered on!
2. The socket-outlet should be near the equipment and should be
easily accessible. To fully disconnect equipment, remove power
cord from its socket.
1) Press the toggle switch on the far-left front panel to the up position. In the up position, the
toggle switch glows red, and the active input button illuminates, as well.
2) Operate the acceptors.
Looping
The looping function enables the operator to extend the number of outputs per input. The
following example describes looping performed by using three amplifiers with one input
and five outputs each: A video signal reaches input of amplifier No. 1. From looping
connector of amplifier No. 1 a cable is connected to input socket of amplifier No. 2. The
loop output of amplifier No. 2 is connected to the input socket of amplifier No. 3. By this
way the input signal is divided into 15 separate output signals. The operator must always
switch to "Hi-z" the termination switch of all the amplifiers but the last. The last
amplifier’ s termination switch should always be at "75 " to maintain well-matched video
