1.1Factors 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	So often ignored, they should be of highest quality, since "Zero
connectors on the	Ohm" connection resistance is the objective. Sockets and
sources and	connectors also must match the required impedance (75ohm in
acceptors	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	Plays a major role in the final result. For long distances
sources and	between sources and acceptors, special measures should be
acceptors	taken in order to avoid cable losses. These include using higher
	quality cables or adding line amplifiers.
Interference from	These can have an adverse effect on signal quality. Balanced
neighboring	audio lines are less prone to interference, but unbalanced audio
electrical appliances	should be installed far from any mains power cables, electric
	motors, transmitters, etc., even when the cables are shielded
