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 describes the VM-1010 Programmable Video Distributor.
4.1 Overview
The VM−1010 is a highperformance distribution amplifier for composite video. It
can also be configured as a 1:5 distribution amplifier for sVideo (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 (sVideo) 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

This section describes the VM-1055 Video Component Distributor.
6.1 Overview
The VM-1055 is a high-performance distribution amplifier for RGBHV video
signals. It provides correct buffering and isolation and distributes the signal to five
identical outputs.
The VM-1055 is a full broadcast, component video /RGBHV distributor designed
for studios, graphics workstations, presentation and other demanding applications.
The VM-1055 splits a five-component input source into five identical outputs, with
no discernible signal degradation. DC coupled inputs and outputs and state-of-the-
art video amplifying circuitry make the VM-1055 the first choice video component
distributor. Signal bandwidth of over 300MHz and the option to adjust the
termination of two "sync" channels (75analog or TTL level) make the unit ideal
for graphics workstations and presentation purposes. The VM-1055 functions as a
5 x 1:5 video DA, for any video source when the termination switch is at "75"
(composite, YC, YUV, RGB and SDI); or as a three analog channel and two TTL
channel distributor.
The unit features:
•High bandwidth of 300MHz (-3dB)
•HDTV compatibility
•Selectable sync input termination of 75(video) or 510(graphics/TTL)
•Standard 19” rack mount size of 1U
