Frequently Asked Questions
Q. So, my PowerCenter has an illuminated meter that monitors changes in incoming voltage.
Why is that important?
A. The voltage meter is essentially a diagnostic tool. It measures between 100-130 volts because that’s the range
that incoming voltage occurs that’s relevant to equipment performance. High-end components like tube amps that
are very sensitive to fluctuations in voltage may experience degraded performance if voltage is too high or too low.
The meter allows you to monitor changes in incoming voltage that are a result of other equipment or appliances
that share the power line going to the circuit breaker (provided you’re not using a separate power line).
If voltage drops below 110V, disconnect your components from the PowerCenter immediately.
Q. What causes changes in voltage?
A. Changes in voltage can occur if your power company switches power sources throughout the day and/or evening.
Or, let’s say you live in a crowded urban area, for example. In the summertime, thousands of people could be using
their air conditioning units simultaneously. This could cause a substantial drop in incoming voltage, which is often
referred to as a ”Brown Out.“
