INTRODUCTION
Congratulations on your purchase of this Kramer Electronics
- Picture-in-Picture Inserter. Since 1981 Kramer
has been dedicated to the development and manufacture of high quality video/audio equipment. The Kramer
line has become an integral part of many of the best production and presentation facilities around the world. In
recent years, Kramer has redesigned and upgraded most of the line, making the best even better. Kramer’s line
of professional video/audio electronics is one of the most versatile and complete available, and is a true leader in
terms of quality, workmanship, price/performance ratio and innovation. In addition to the Kramer PIP-200 such
as the one you have just purchased, Kramer also offers a full line of high quality switchers, distribution
amplifiers, processors, interfaces, controllers and computer-related products.
1.1 Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from a source to an acceptor
which are described in Table 1:
Table 1: Factors Affecting Quality of Results
FACTOR
EFFECT
Connection cables
Low quality cables are susceptible to interference; they degrade
signal quality due to poor matching and cause elevated noise
levels. They should therefore be of the best quality.
Sockets and
connectors on 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 end 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
between sources and acceptors, special measures should be
taken in order to avoid cable losses. These include using higher
quality cables or adding line 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
