•Computer RGB or component video distribution
2 VM-1010, VM-1021, VN-1055, VM-54 - Getting Started
2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
•Use Kramer high-performance, high-resolution cables
•Use only the power cord that is supplied with this machine
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer product away from moisture, excessive sunlight and
dust
Caution: There are no operator serviceable parts inside the unit
Warning: Disconnect the power and unplug the unit from the wall
before installing
Your amplifier is pre-calibrated at the factory for
transparent operation. Re-tuning it can upset signal
transparency.
Do not attempt to adjust the LEVEL trimmers without
using accompanying standard calibrated oscilloscope
or waveform monitor!

This section provides instructions for rack mounting the 1U devices. 2U and 3U
devices use the same procedure with longer rack “ears” and additional screws.

This section describes the VM-1010 Programmable Video Distributor.
4.1 Overview
The VM−1010 is a highperformance distribution amplifier for composite video. It
can also be configured as a 1:5 distribution amplifier for sVideo (Y/C) signals and
has controls to compensate for signal losses inherent in long cable runs.
The VM−1010 is designed for studio and other demanding applications. It has two
looping video inputs, each splitting to 5 outputs. The user may select 2x1:5 or 1:10
operation via front panel control switches. Several VM-1010 units may be chained
through the looping inputs. Output signals are DC or AC coupled (user selectable)
for maximum flexibility.
The unit features:
•High bandwidth of 235MHz (3dB)
•Dual-mode configuration either as a 1:10 (composite) or a 1:5 (sVideo) 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 1U
Figure 1 and Figure 2 define the unit.

4.2 Connecting the VM-1010
Always switch off the power to each device before connecting it to your
VM-1010. After connecting your VM-1010, connect its power and then
switch on the power to each device.
To connect the VM-1010 as illustrated in the example in Figure 3:
1. Connect up to two video sources (for example composite video players) to
CHANNEL A INPUT A and CHANNEL B INPUT B BNC connectors.
2. Connect up to five video acceptors (for example, composite video recorders)
to each channel.
3. As required, select the coupling and termination, the MODE (2x1:5 or 1:10)
and adjust the EQ and LEVEL of each channel as needed.

Note:
•Terminate unused inputs to 75, and terminate active inputs at the
connecting source
•Remember, the output signal format matches the input signal format (for
example, if the input is composite, the output is composite)
•All signal cables to each device should be of equal length (for example, the
R,G,B cables between a camera and the amplifier should be of equal length)
