GETTING STARTED
The fastest way to get started is to slow down and do everything right the first time. Taking 15 minutes to read
the manual may save a few hours later, and usually there is no need to read the whole manual. Since each
section opens with an overview of the section, users may determine its necessity for their particular needs.
3.1 Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted via coaxial cable from a
source to an acceptor:
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 of the sources and acceptors
- So often ignored, they should be of highest
quality since "Zero Ohm" connection resistance is the target. Sockets and connectors must also 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
(over 15 meters) between sources and acceptors, special measures should be taken in order to avoid cable
losses. These include using higher quality cables, adding line amplifiers, or using twisted pair or fiber optic
codecs.
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 main power cables, electric motors, transmitters, etc., even when the cables are shielded.
3.2 Optional Accessories
The following accessories, available from Kramer, can enhance implementation of other Kramer devices. For
information regarding cables and additional accessories, contact your Kramer dealer.
