Why Your Recording Studio Needs an Isolation Transformer August 4, 2017

Why Your Recording Studio Needs an Isolation Transformer, Whittier, California

An isolation transformer is a device that transfers electricity from an AC power source to one or more pieces of equipment without using a direct connection. This transformer serves an important safety purpose because it blocks direct conduction flow, so you avoid the possibility of electric shock. When used in recording studios, it also prevents electrical buzzing that can interfere with sound quality. This guide explains how these devices work and why you need one in your studio.

How Does an Isolation Transformer Work?

isolation transformer Pico Rivera CAAn isolation transformer consists of two electromagnets, or coils of copper wire, that are wound in such a way that the primary coil induces a current in the secondary one. The voltage of the induced current could be higher, lower, or the same as that of the primary coil. Since there is no direct connection between the two, any equipment attached to the secondary coil is isolated from all other electrical activity. This provides a balance between the power source and equipment, eliminating overtones like humming and buzzing. 

Why Is This Equipment Important for Your Recording Studio?

Unwanted electrical noise can interfere with audio recordings and broadcasts. Microphones pick up buzzing and humming tones from other active devices if they are not isolated. This noise can come from many sources, but fluorescent lighting and dimmer switches are especially problematic. A nearby vacuum cleaner, air conditioner, or furnace fan can also ruin an otherwise perfect recording.
