Getting To Know Your VM-54 Amplifier
The KRAMER VM-54 is a high quality, state-of-the-art, Video/Component Distribution
Amplifier designed for studio and other demanding applications. The VM-54 has three
looping input channels each with 18 outputs. With this configuration a 1:18 RGB
distributor can be formed. Each channel is subdivided into four groups of five or three
outputs, which may be tuned separately for gain and cable EQ. The three input channels
may be looped-through together to form a 1:54 DA, or other configurations (e.g. 1:18
Composite or 1:18 YC - using two channels). To form a 1:54 distributor, the channel 1
LOOP connector should be connected to the input connector of channel 2. The channel 2
LOOP connector should be connected to the input connector of channel 3. The termination
switches of channels 1 and 2 should be set at "Hi-z" and the channel 3 termination switch
should be set to "75 ". Output signals may be AC or DC coupled via front panel controls.
Signal bandwidth exceeding 350 MHz makes the VM-54 the first choice for a large
video/component distribution center.
Front/rear panel features of the VM-54 are described Figure 7, Table 10 and Table 11.
