This section describes the VM-54 Video/Component Distributor Amplifier.
7.1 Overview
The VM-54 is a high-quality video/component distribution amplifier designed for
studio and other demanding applications. The unit 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 (for
example, a 1:18 Composite or 1:18 YC - using two channels). To form a 1:54
distributor, connect the channel 1 LOOP connector to the input connector of
channel 2. Connect the channel 2 LOOP connector to the input connector of
channel 3. Set the termination switches of channels 1 and 2 to "Hi-z" and set the
channel 3 termination switch to "75Ω". Output signals may be AC or DC coupled
via front panel controls. Signal bandwidth exceeding 350MHz makes the VM-54
the first choice for a large video/component distribution center.
The unit features:
• High bandwidth of 365MHz (-3dB)
• HDTV readiness
• Dual-mode configuration either as a 1:54 (composite/SDI) or a 1:18
(component) DA
• Grouped level (gain) and EQ (peaking) controls
• A video AC/DC coupling selection
• Looping inputs
• Selectable input signal termination
• Standard 19” rack mount size of 2U with built-in rack “ears”
