CTS AV Signal Flow and Distribution 1

Question 1

What does the term 'signal flow' refer to in an AV system?

Accepted Answer

The path audio and video signals travel from source to destination

Answer

Signal flow describes the path that audio and/or video signals take from the source device through processing and distribution equipment to the output devices.

Question 2

Which connector type is most commonly used for balanced analog audio in professional AV installations?

Accepted Answer

XLR

Answer

XLR connectors are the standard for balanced analog audio in professional AV systems due to their locking mechanism and common-mode noise rejection.

Question 3

What is the primary advantage of using balanced audio cabling over unbalanced in a long AV cable run?

Accepted Answer

Rejection of common-mode noise and interference

Answer

Balanced audio uses two conductors with opposite polarity, allowing the receiving device to cancel out electromagnetic interference picked up along the cable run.

Question 4

In video signal distribution, what does the term 'distribution amplifier' (DA) accomplish?

Accepted Answer

Splits and amplifies a single video signal to multiple outputs without degradation

Answer

A distribution amplifier takes one video input and drives multiple identical outputs while restoring signal strength lost from splitting.

Question 5

What is 'impedance matching' critical for in AV signal distribution?

Accepted Answer

Ensuring maximum power transfer and minimizing signal reflections

Answer

Proper impedance matching ensures maximum power transfer between devices and prevents signal reflections that cause degradation, especially at high frequencies.
