Room Correction
8 Specifications Are Subject To Change Without Notice
IQ Subwoofer Power Amplifier
The 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
is truly an
intelligent system. 20Hz, 30Hz and 40Hz frequencies can be cut or boosted by a
whopping 6dB, 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.)
