What is series mode surge protection?

Series mode surge protectors use a large, carefully designed inductor in the hot or live circuit and other circuitry to roll off high frequency / high rate of change transients. The technology was developed and patented by Jack Hartford of ZeroSurge and is licensed by a small number of other companies who know what they […]

What shunt mode surge protection?

Shunt mode surge protectors are typically based on circuits that contain metal oxide varistor (MOVs) which, under normal operating voltages, act as an open circuit and allow no current to flow through them. The MOVs will start to conduct should the voltage level rise above the clamping voltage of the MOVs (i.e. a surge condition), […]

What is a whole house surge protector?

A whole house surge protector is a device connected at your service panel that provides protection from ‘big’ surges such as lightning strikes. Most residential houses are supplied with two 120V legs and so a whole house surge suppressor designed for such an installation would typically have ‘four mode’ protection: live 1-neutral, live 1-ground, live […]

What is a surge protector?

Simply put, a surge protective device (SPD) is a device designed to protect against damaging and dangerous short, high voltage transients that are created by devices outside or inside the home or studio. There are many different protection mechanisms that are used in surge protectors. The principal ones being voltage breakdown (e.g. gas discharge, voltage […]

Power and Grounding: The Acoustic Frontiers Approach

We recently spent some serious research & development time developing what could be called the Acoustic Frontiers approach to power and grounding for audio, home theater and studios.

Here are some of the juicy topics covered on our power pages:

  • Why should you care about how your system is powered and grounded?
  • What is the anatomy of the power and grounding system feeding your AV gear?
  • Do you know that there are 8 power and grounding issues that can affect the performance and lifespan of your AV system?
  • What are the causes and cures of 60Hz hum and powerline harmonic buzzing?
  • Why are 99% of all (Metal Oxide Varistors) no good for AV equipment?
  • Why do you need a UPS for your projector?
  • What is the concept of whole room power conditioning?
