Room Correction | XJ-600RSubwoofer Power Amplifier |
| |
The XJ-600R offers a room correction technique that surpasses that of all previous attempts. The intelligent “Back EMF” drive circuit interacts with the subwoofer design and memorizes system tuning frequencies and system type. The information which is stored in microprocessor turns on a preset group delay curve that serves as a correction reference. This information deals only with time correction that moves the peaks and the dips in a room to a flat. Once that is achieved the user will resort to the final correction- EQ the room. For that reason Earthquake’s XJ-600R is truly an intelligent system. 20Hz, 30Hz and 40Hz frequencies can be cut or boosted by a whopping 12dB, these corrections help in producing wider range of listening position that is unprecedented for the room.
(Note: boosting the response at 20Hz is very demanding for your subwoofer. Consult with your subwoofer maker, and determine if their subwoofer is designed to take a boost at such low frequencies.)
When setting the room EQ, DO NOT over power the speakers as this may cause them to bottom out or cause other more severe problems that your warranty will not cover. To set up the room EQ, you will need a Spectrum-Analyzer, or you can use the rule of thumb.
