Earthquake XJ-300 FR

The special XJ technology also allows for a novel 2.1 configuration. With the XJ-300FR, it is possible to connect a third speaker between the 2 main channels. This matrix mono channel plays the combined content of both channels and is extremely useful for powering 2 satellites and a subwoofer. Adding to this flexibility is the new patented EQ Interlock design—two amplifiers can be linked together resulting in a 4 channel amplifier using only 1 rack U of space.

To begin any size installation, all you need is a given number of XJ-300FR amplifiers. You no longer have to buy a cumbersome mix of different amplifiers to achieve a certain number of channels or power level. With endless configuration scenarios, the XJ-300FR amplifiers can be used as mono (bridged) amplifiers, 2.1 channel amplifiers, 2-channel amplifiers, 4/8/12 and 16 channel amplification with industry leading power density and efficiency.

Approaching 99 percent efficiency, the XJ amp never gets hot and can be placed in a tight rack with components on all sides. At only 1 rack U high and half a rack in width, this is an amazing achievement.

The XJ-300FR produces continuous rock solid power - 110 Watts RMS at 8 ohms per channel and 300 Watts RMS bridged into 4 ohm. This massive power capability is possible due to the advanced nature of the patented Class J output stage. The switching frequency of the output and the voltage of the power supply are modulated in real time based on the frequency and amplitude content of the input. No other amp can match the efficiency and power of Class J.
