Introduction

IQ Subwoofer Power Amplifier

 

 

Congratulations and thank you for choosing the new Earthquake IQ1500 Subwoofer Power Amplifier as a key component for your audiophile system. The IQ1500 amplifier is designed to meet the highest standards of performance and sound quality. In addition Earthquake Sound’s IQ certification and patented Class “J” circuitry ensure that the amplifier meets and exceeds all industry standards. The new IQ1500 amplifiers include many unique technologies that allow it to deliver “World Class” performance, even under extreme operating conditions.

The IQ1500 is a ruggedly constructed high quality professional amplifier. The Digital feedback class “J” Circuitry, allows the amplifier to produce massive amounts of power with minimal heat production. This patented circuitry delivers high efficiency in the range of 99%- The typical class AB amplifier runs at about 40 to 50%.

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.)

CAUTION: The IQ1500 is capable of generating high sound pressure levels. You should exercise caution when operating this amplifier system. Long term

exposures to high levels of sound pressure will cause permanent damage to your hearing. Sound pressure levels exceeding 85dB can be dangerous with constant exposure. Set your audio system to a comfortable loudness level. Earthquake Sound Corporation does not assume liability for damages resulting from the direct use of the IQ1500 , and urges users to play the IQ1500 at moderate listening levels.
