⚠️¡Cuidado! FALLAS ELECTRICAS que pueden ARRUINAR tus Altavoces y COMO SOLUCIONARLO

Each time, amplified speakers and power amplifiers, and amplifiers type AB, H, D or T, have a common enemy, the variations of voltage in different regions of Latin America, due to the precarious service of electrical fluid of many companies of public services. Why are power amplifiers of any kind damaged? One of the reasons is overvoltages, undervoltages, very high unexpected peaks, electrical storms, lack of security without placing a ground pole. The voltage regulator is designed to protect sensitive electronic equipment from problems caused by AC line voltage irregularities, such as blackouts, brownouts, and overvoltage conditions. Such irregularities can cause audio pitch shifts, malfunction of digital equipment (such as loss of MIDI programs or other data), or, in extreme cases, permanent damage. Power Conditioning Definitions voltage regulation AC line voltage is a number that represents the nominal electrical potential that has been adopted in a region to power electrical equipment of all kinds. In most of North America, the line voltage is 120 VAC. Actual voltage may fall below or rise above this nominal level due to brownouts, power outages, use of poor wiring, and other causes. These deviations may cause poor performance or malfunction. A voltage regulator is a device that, through the use of an autotransformer, corrects deviations in line voltage by changing transformer taps such that the output voltage is at or near the nominal AC line voltage level. the. Spikes (also called spikes or transients) The spikes can have voltages up to 6000 volts. Although they are usually very short-lived, the energy they contain can be considerable and enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an inescapable component of electrical energy. They are unpredictably caused by electric motors turning on or off (on the premises or outside), utility company maintenance, nearby lightning strikes, and other factors. Spikes are absorbed by special components called MOVs inside the M-8x AR to provide safe voltage levels to protect your equipment. RFI/EMI interference RFI (Radio Frequency Interference) or EMI (Electromagnetic Interference) noise involves lower voltages and less energy than is found in peaks, but is continuous or transient. It's not likely to cause physical damage, but it can certainly be annoying, producing static on audio circuits, “snow” on video screens, or distorted data on computers. Nearby radio transmitters, certain types of lighting, electric motors, and other devices can introduce noise onto AC lines. Because RFI/EMI noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effectively reduced through the use of low-pass filtering. Extreme voltage protection The M-8x AR includes special circuitry to detect over and under voltage conditions and regulate or disable the output before connected equipment can be damaged. See specifications for exact voltages at which shutdown occurs. When the input voltage drops out of the regulation limit, the power will be cut off. Power will automatically restore when the condition has subsided. The two red LEDs labeled "EVS" indicate a protective shutdown condition. Extreme current protection The M-8x AR includes a special ECS circuit to detect an extreme overcurrent condition and shut down the outlets before the M-8x AR or its connected equipment is damaged. The ECS circuit has been designed to detect high speed, high level currents and will ignore low speed/low current transients such as amplifier inrush currents. When an ECS condition is detected, the M-8x AR will close the outlets and illuminate the red extreme current LED.
