IQ Subwoofer Power Amplifier

Room Correction

The

IQ1500

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

IQ1500

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.)
