Cables and Patching

Question 1

TRS

Answer 1

Balanced quarter inch
Sleeve is the ground

Question 2

NORMAL VS HALF VS NON

Answer 2

Fully Normalled: A cable inserted into either top or bottom jack breaks the internal connection and signal now flows through the patch cable.

Half Normalled: plugging a patch cable into the top jack does not break the signal, but creates a Y split.

Question 3

Coaxial cable

Answer 3

The middle longer part is positive and the ring around it is negative. They share the same axis and are used for digital clocks

Question 4

Very long guitar cables

Answer 4

Lose high frequencies due to high impedance, are subject to more noise interference because they are unbalanced

Question 5

XLR Cables are technically not balanced without…

Answer 5

1. Balanced input
2. Cable with 3 wires
3. Balanced output

Question 6

How do balanced cables work?

Answer 6

One positive signal, one ground, one inverted phase signal. #1 is ground always. In the INPUT of the cable, the clean sound will be doubled and the noise will be cancelled when the inverted phase signal is flipped
