Unpacking System Components
• Keep the original carton and packing materials for future shipment or
storage.
• Check for any visual signs of damage. If you encounter any concealed
damage, consult your Earthquake Sound dealer before proceeding with unit
installation.
• Retain the sales receipt as it establishes the duration of the limited warranty
and provides information for insurance purposes.
System Installation Considerations
There are several factors to consider before installing Earthquake Sound’s
XJ-300ST
.
• What are the intended listening zones?
• What system options and accessories might be required for features such as
local sources, etc.?
• From where in each zone will the listener prefer to control the system? Where
will the remote gains be located? Where will the speakers be located?
• Where will the source equipment be located?
Connection Tips
• Keep all power cords away from all signal cables to prevent humming from
induced noise.
• Choose reliable signal cable cords (Earthquake Sound also specializes in
high-performance RCA cables and patches).
• All speaker wires that are ran through the walls should be twisted to reduce
potential hum noise pick up.
• Label both ends of all wires with the corresponding room location.
• It is best to use a grounded electrical outlet to power the amplifier. Lack of
input ground reference could be unsafe. Consult your electrical contractor
about proper grounding.

Introduction
The XJ-300ST amplifier is an extremely versatile and modular amplifier. It can be
used as a two channel, 2.1 channel, or bridged as a 1 channel amplifier. The XJ-
300ST runs completely cool while outputting twice the power of most amplifiers
its size. Therefore, it is extremely flexible and can be used in many different
applications.
Multiple Mounting Options
The XJ-300ST is only one rack space tall and has a half-rack width chassis.
This smart design features a patented interlocking design so two XJ-300STs
can be connected side by side and be rack mountable. Other amplifiers of
the same size run too hot to mount them near anything else which defeats
the purpose of their size. Because the XJ-300STs run completely cool, you
can comfortably mount other components directly above or below them in
the rack. This means ultimate convenience for the installer. There are also
additional mounting holes on the sides of the amplifier so that short brackets
can be attached and the amp can be mounted directly to a wall or inside a
cabinet.
Speaker Set-up Options
One or two XJ-300STs can power a 2.1 channel system. This depends on
how much power you want to output to your speakers. One XJ-300ST can
be used for two speakers while the other can be bridged as a monoblock.
Alternatively, you can use two linked XJ-300STs as a 4 channel system. For
a more high powered system, bridge both of them and designate one speaker
or sub to one amplifier and another speaker or sub for the other. The installer
is completely in charge of how the amplifier’s power is distributed.
Applications
The XJ-300ST has countless applications because of how customizable the
channel set-up is. If you need to install in-ceiling speakers in the kitchen,
tower speakers in the living room, or rock speakers outside, the XJ-300ST
can perform accurately in every situation.
