Line Conditioners and Protectors
Although the DEQ830 is designed to tolerate typical voltage variations, in today’s world the voltage coming from the AC line may contain spikes or transients. These can cause audible noises, and they can stress your gear and, over time, possibly cause a failure. There are two main ways to protect against this, listed in ascending order of cost and complexity:
•Line spike/surge protectors. Relatively inexpensive, these are designed to protect against strong surges and spikes, acting somewhat like fuses in that they need to be replaced if they’ve been hit by an extremely strong spike.
•Line filters. These generally combine spike/surge protection with filters that remove some line noise (dimmer hash, transients from other appliances, etc.). A good example is the Isobar™ series from Tripp Lite.
Care and Maintenance
Cleaning
Disconnect the AC power supply, then use a damp cloth to clean the DEQ830’s metal and plastic surfaces. For heavy dirt, use a
Do not spray cleaning solution of any sort onto the front panel of the DEQ830. If a cleaning becomes necessary, spray a recommended cleaning solution onto a cloth first, and use the cloth to clean the front panel.
