4 Connectivity - Section 2

Question 1

Name the types of analog cables

Answer 1

Speaker wire, coaxial, single conductor, two conductor wire with conductive shield, multi-conductor.

Question 2

What are analog signals, in the fundamental scientific sense?

Answer 2

Low-Voltage Electricity

Question 3

What is standard microphone level?

Answer 3

Approximately -60db

Question 4

What is, typically, instrument level?

Answer 4

-20 to -30 dB

Question 5

What is “consumer” line level, and “pro” line level, respectively?

Answer 5

-10db, +4 db

Question 6

What is the difference between balanced and and analog connections?

Answer 6

Balanced connectors use three components - hot, wire, and ground. Balanced connections allow signals to travel a longer distance without degrading. They are typically used between a mic and a pre-amp. Unbalanced connectors consist of two components and degrease more quickly through a cable. They are typically used between an electric guitar and an amp.

Question 7

Can you have cables with different types of connectors on either end?

Answer 7

Yes you can, but it’s complicated.

Question 8

What is the equations for the signal transmitted through a balanced connection?

Answer 8

(A+Noise)-(A-Noise) = A+Noise+A-Noise= 2A

Question 9

How much greater is the signal strength of a balanced connection - compared to an unbalanced connection?

Answer 9

Two times as great. (2A).
