Introduction
Congratulations and thank you for choosing the new Earthquake
Subwoofer Power Amplifier as a key component for your audiophile system.
The
IQ600
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
IQ600
amplifiers include many unique technologies that
allow it to deliver "World Class" performance, even under extreme operating
conditions.
The
IQ600
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%.

IQ600
The
IQ600
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
IQ600
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:
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 IQ600 , and urges users to
play the IQ600 at moderate listening levels.
IQ Suboowfer Power Amplifier
is truly an intelligent system. 20Hz, 30Hz and 40Hz
The IQ600 is capable of generating high sound
pressure levels. You should exercise caution when
operating this amplifier system. Long term
