Introduction

The XJ-300FR 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-300FR 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-300FR is only one rack space tall and has a half-rack width chassis. 
This smart design features a patented interlocking design so two XJ-300FRs 
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-300FRs 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-300FRs  can  power  a  2.1  channel  system.  This  depends  on 
how  much  power  you  want  to  output  to  your  speakers.  One  XJ-300FR  can 
be  used  for  two  speakers  while  the  other  can  be  bridged  as  a  monoblock. 
Alternatively, you can use two linked XJ-300FRs 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-300FR 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-300FR 
can perform accurately in every situation.
