LINE AMPLIFIERS
This section describes all the controls and connections of your line amplifier. Understanding the controls and
connections helps you realize the full power of your line amplifier.
5.1 Getting to Know Your VM-9S Amplifier
The KRAMER VM-9S Video/Audio Line Amplifier is a high quality amplifier which compensates for video
and audio signal losses when long cables are used. In any video/audio setup requiring considerable distances
between video/audio source and acceptors, signal loss and thus depreciation in the quality of both picture and
sound is a real problem. To prevent this phenomenon, a VM-9S amplifier is installed adjacent to the video/audio
source. The line amplifier may also be used as a 1:2 video/stereo audio (compensated) distributor. Front/rear
panel features of the VM-9S are described in Figure 1 and Table 1.
NOTE
For operation instructions refer to section 9.
