Furman M-8x AR Voltage Regulator

Furman M-8x AR Voltage Regulator




Furman M-8x AR Overview



The M-8x AR Voltage Regulator from Furman is intended to protect your sensitive electronic equipment from problems caused by AC line voltage irregularities such as brownouts, sags, and over-voltage conditions. Such irregularities can cause audio tonal changes, digital equipment malfunctions such as loss of MIDI programs or other data, or in extreme cases, permanent damage. The M-8x AR can be used in a variety of pro audio and A/V applications common in studio recording, live sound reinforcement and other scenarios.
