A Thank You Note.

Thank you for purchasing this XJ-1000FR amplifier. Designed to exceed all your expectations for audio amplification, the XJ­1000FR is a ruggedly constructed high quality professional amplifier equally suited for home or professional use. It is ideal for
high fidelity full range stereo reproduction, heavy duty sub-woofer application, powerhouse for multiple tactile transducers,
and a variety of other home and studio applications.

Keywords describing the XJ-1000FR are: flexibility, power, control, and adaptability. It is the perfect amplifier for the advanced
enthusiast who wants full control and ability to adjust all parameters of operation. Similarly, it can easily be used by the novice
user who wants large amounts of power from a compact and efficient amplifier. The XJ-1000FR is passively cooled for silent
operation. The brute force of the XJ-1000FR springs from the class “J” circuitry. Earthquake patented Class “J” technology
manifests as a “quantum leap” in amplifier technology.

The revolutionary Class “J” is able to combine high efficiency (99%) with an extraordinary bass control. Class “J” is an evolution
of PWM technology, it combines advanced multi-level digital feedback with an intelligent controller (DCDC). It modulates the
power supply voltage and output switching frequency in real time based on the frequency and amplitude of the input signal.

This added level of intelligence results in several obvious advantages: increased thermal headroom through the amplifier's
optimum energy use, dramatically improved bass response and dynamic power capabilities. This results in a harder more solid
audible impact that adds a drive to the sound normally experienced only at live concerts. We invite you to experience the
immense power and superior sound quality of the XJ-1000FR
