Supplying Power
The FX7, like any piece of computer hardware, is sensitive to voltage drops, spikes, and surges. Interference such as lightning or power "brownouts" can seriously, and in extreme cases, permanently damage the circuitry inside the unit. Here are a few tips that will help you get the best possible performance out of your FX7 while avoiding damage:
•Always make sure you have a "clean" power source for connect- ing to the FX7. This means that the AC power line you connect to the FX7 should be as free from voltage fluctuations and RF interference as possible. In recording environments, "clean" power is also important in preventing AC hum or buzz from get- ting to tape.
•Use a good quality spike / surge suppressor (also called a power strip). This is an inexpensive solution to all but the most severe AC line conditions. A good quality power strip can save you a lot of money in repair bills because they prevent large spikes and surges from reaching your equipment. Also in this category (but more expensive) are rackmount power supplies. Some of these, like the DOD 828, have retractable light tubes and RF filtering.
•Although more expensive, AC line conditioners offer the best protection from improper line voltages. Line conditioners con- stantly monitor the AC line for excessively high or low voltages and instantaneously compensate to deliver a consistent voltage to the connected equipment.
•Always make sure that your audio lines are as far as possible from power cables. This will further prevent noise, hum, and stray magnetic fields from entering your signal path. If audio and power lines must run close to each other, try to avoid run- ning them parallel to one another.
