Alesis DEQ830 사용자 설명서

 

 

 

 

 

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.  

 

 

 

Disconnect the AC power supply, then use a damp cloth to clean 

the DEQ830’s metal and plastic surfaces. For heavy dirt, use a 

non-abrasive household cleaner such as Formula 409™ or 

Fantastik™. DO NOT SPRAY THE CLEANER DIRECTLY 

ONTO THE FRONT OF THE UNIT AS IT MAY DESTROY 

THE LUBRICANTS USED IN THE SWITCHES AND 

CONTROLS! Spray onto a cloth, and then use the cloth to clean 

the unit.
