The IQ600 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 IQ600 , and urges users to
play the IQ600 atmoderate listening levels.

Congratulations and thank you for choosing the new Earthquake
Subwoofer Power Amplifier as a key component for your audiophile system.
The 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 amplifiers include many unique technologies that
allow it to deliver “World Class” performance, even under extreme operating
conditions.
The 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 classAB amplifier runs at about
40 to 50%.

The offers a room correctiontechnique thatsurpasses thatof allprevious
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 peaksand the dips in aroom to a flat. Oncethat is
achieved the user willresort tothe final correction-EQ theroom. For thatreason
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 thatis 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.)
