Balanced Field Length

--

Balanced field length is the optimal length of a balanced audio cable to minimize signal degradation.

Where:
Distance is the distance from the source to the destination.
Cable Velocity of Propagation is the percentage of the speed of light the signal travels through the cable.
Cable Length is the actual length of the cable being used.

Learn how to use the Balanced Field Length Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the distance from the source to the destination in meters.
  2. Enter the cable velocity of propagation as a percentage (typically 66% for copper cables).
  3. Enter the actual length of the cable being used in meters.
  4. Click the "Calculate" button to determine the balanced field length.
  5. The result will show the optimal balanced field length in meters.

Working Principle

The balanced field length is calculated based on the distance from the source to the destination, the velocity of propagation through the cable, and the actual cable length. The formula used is:

Balanced Field Length = (Distance / Cable Velocity of Propagation) - Cable Length

This calculation helps ensure that the audio signal remains intact by minimizing signal degradation over long distances.

Example

For example, if you have a distance of 100 meters from the source to the destination, using a cable with a velocity of propagation of 66%, and the cable length is 50 meters, the balanced field length would be:

Balanced Field Length = (100 / 0.66) - 50 = 52.27 meters

In this case, you would need to ensure that the balanced field length does not exceed 52.27 meters to maintain signal integrity.
