XJ-300ST Stereo Amplifier

XJ-300ST Stereo Amplifier

The Earthquake XJ-300ST stereo amplifier packs more power and flexibility than any other amplifier. No amplification task is beyond its capability. With an unimposing miniature size and almost unreal amounts of cool running power, this advanced Class J amplifier is the installer’s go-to dream.

The XJ300ST is also exciting news for the tactile transducer/bass-shaker market, as it sports all the features of the XJ-300R while adding a whopping 20 percent more power.

The special XJ technology allows for a novel 2.1 configuration. With the XJ-300ST, connecting a third speaker between the two main channels is possible. This matrix, mono channel plays the combined content of both channels. This is extremely useful for powering 2 satellites and a subwoofer.

2.1 Speaker Setup

Earthquake’s proprietary interlocking design adds to the unique flexibility of the XJ-300ST, allowing users to attach two amplifiers together, resulting in a 4-channel amplifier using only 1U of rack space. The XJ-300ST can also be mounted on the wall or inside the cabinet by fastening the short mounting ears to the pre-assigned holes on the side of the amplifier.

With endless configuration scenarios, the XJ-300ST 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.

All the installer or avid user needs to begin any size installation is a given number of XJ-300ST amplifiers. No need to buy a cumbersome mix of different amplifiers to achieve a certain number of channels or power levels. Besides the simplicity, this is an inventory dream for any installer.

Need a subwoofer amp? grab 1 x XJ-300ST. Need a 4-channel amp? grab 2 x XJ-300ST. Need to wire a complete 7.1 system with very large front speakers? Grab 5 x XJ-300ST. Bridge one for each LCR and use the remaining two for the 4 rear channels. All this uses only 3U of rack space!

Upwards of 90 percent efficiency, the XJ-300ST stereo amplifier is cool-running and can be placed in a tight rack with components on all sides. This is an amazing achievement at only 1U rack high and half a rack in width.

The XJ-300ST produces continuous rock-solid power of 110 WRMS at 8-Ohm per channel and 320 WRMS bridged into 8-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 amplitude of the power supply is modulated in real-time based on the frequency and amplitude content of the input. No other amp can match the efficiency and power of Earthquake’s Class J technology.
