1.1
A Word on Video/Audio Distribution Amplifiers
Video/Audio Distribution Amplifiers described in this manual, distribute one signal to several users. They vary
in the number of outputs, operating format and bandwidth. Video/Audio distribution amplifiers are used to
distribute one source to several acceptors (monitors, audio devices etc.) for simultaneous recording or
monitoring of one source, with no discernible signal degradation. A good quality distributor amplifies the
incoming signal, pre-compensates the signal for potential losses (resulting from the use of long cables, noisy
sources, etc.) and generates several identical buffered and amplified outputs. Often, a signal processor is
inserted between the source and the distribution amplifier for correction and fine-tuning of the source signal
before multiplication, so that all copies are corrected in the same way. Typical applications of the machines are:
audio/video duplication, studios delivering undiminished quality duplicates and video showrooms delivering an
identical signal to several acceptors. The front panels of these Kramer distribution amplifiers are designed to be
simple to operate.
1.2
Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from a source to an acceptor:
Connection cables
- Low quality cables are susceptible to interference; they degrade sign al quality due
to poor matching and cause elevated noise levels. They should therefore be of the best quality.
Sockets and connectors of the sources and acceptors
- So often ignored, they should be of highest
quality, since "Zero Ohm" connection resistance is the objective. Sockets and connectors also must
match the required impedance (75ohm in video). Cheap, low quality connectors tend to rust, thus causing
breaks in the signal path.
Amplifying circuitry
- Must have quality performance when the desired result is high linearity, low
distortion and low noise operation.
Distance between sources and acceptors
- Plays a major role in the final result. For long distances
(over 15 meters) between sources and acceptors, special measures should be taken in order to avoid cable
losses. These include using higher quality cables or adding lin e amplifiers.
Interference from neighboring electrical appliances
- These can have an adverse effect on signal
quality. Balanced audio lines are less prone to interference, but unbalanced audio should be installed far
from any mains power cables, electric motors, transmitters, etc. even when the cables are shielded.

HOW DO I GET STARTED?
The fastest way to get started is to take your time and do everything right the first time. Taking 15 minutes to
read the manual may save you a few hours later. You don’t even have to read the whole manual. If a section
doesn’t apply to you, you don’t have to spend your time reading it.

Optional Accessories
The following accessories, which are available from Kramer, can enhance implementation of your distribution
amplifier. For information regarding cables and additional accessories, contact your Kramer dealer.
Rack Adapter - Used to install smaller machines in a standard 1U rack. One or more machines may be
installed on each adapter.
BNC "Y" Connector - Used for looping purposes and splits the incoming signal to enable connection of
an additional machine.
SP-11 - (Video/Audio Processor) can be serially connected between the video/audio source and the
distribution amplifier for video and audio control/correction. The machine provides camera control and
luminance/white balance correction. The SP-11 is also capable of performing composite to Y/C conversion
and bi-directional transcoding. The machine allows full control over the video signal: video gain down to full
fade, log or linear definition control, log or linear contrast control, color saturation control, black level
control, red, green and blue controls and a screen splitter control for “before-after” comparison. The Input
switch control is "audio-follow-video".
104L - (Video Line Amplifier) can be serially connected between the video source and the distribution
amplifier for video line amplification and cable compensation, video field work and SDI signal distribution.
Signal loss and the resulting depreciation in pictur e quality is a real problem in any video setup requiring
considerable distance between video source and acceptors. The 104L video line amplifier, one of the
KRAMER TOOLS, is a high quality amplifier, which prevents video signal losses over long cables. For best
results the 104L amplifier is installed adjacent to the video source. The 104L is housed in the compact
KRAMER TOOLS enclosure and is fed by a 12VDC source. High bandwidth and front accessible controls
make it suitable for the most demanding analog and SDI studio applications.
4x1VB - (4x1 mechanical switcher) can be serially connected between the composite video sources and the
distribution amplifier for video switching. It is designed for composite video signals using BNC connectors.
It accepts up to four inputs and allows the user to select any input to be routed to one output using buttons
located on the side panel. High quality switching components are used to ensure minimal crosstalk and very
high bandwidth. The entirely passive design of the 4x1VB eliminates the need for a power supply.
Unselected inputs are automatically terminated into a 75ohm resistor. The 4x1VB is part of the Kramer
TOOLS family of compact, high quality, cost effective solutions for a variety of applications.
VS-801xl- (8x1 Composite/Single Component Video & Unbalanced Audio Switcher) allows several
video/audio sources to be connected to its inputs for switching. The machine provides truly effortless
switching between eight video/unbalanced audio inputs and one output. Switching is done during vertical
interval, either of source no. 1 or of the video available on the external sync socket. The switcher may be
controlled by touch buttons or by contact closure via a remote socket on t he back of t he machine. Video signal
bandwidth is 225MHz (typical), allowing the machine to be used in the most demanding applications.
VIDEO TESTER - A new, unique, patented, indispensable tool for the video professional, the Video
Tester is used to test a video path leading to/from an amplifier. By pressing only one touch switch it can trace
missing signals, distinguish between good and jittery (VCR sourced) signals, and identify the presence of
good signals. Whenever a video signal is missing, because of bad connections, cable breaks or faulty sources,
the Video Tester is all you need.
