MOON W-3 Stereo Power Amplifier 
 
 
Connecting the W-3
 
 
 
1.  Connect the input cables running from your preamplifier’s outputs, whether balanced or single-
ended, to the amplifier’ s XLR or RCA inputs respectively.  We highly recommend that you use the 
balanced XLR inputs (provided that your preamplifier has balanced outputs) to take full advantage 
of  MOON W-3 Stereo power amplifier’s capabilities.  Please refer to the next section “Balanced 
Operation” on page 9 for further information.  
 
In the event that you are using single-ended RCA interconnects, you should use the amplifier’s RCA 
female jacks labeled “+” and leave the “dummy” RCA termination plugs in the “-“ RCA female jacks.  
If your preamplifier inverts phase, then your should use the RCA female jacks labeled “-“ and insert 
the dummy RCA termination plugs into the “+” RCA female jacks. 
 
     Don’t hesitate to use high quality interconnect cables. Poor quality interconnect cables can degrade 
the overall sonic performance of your system.  It is recommended, though not mandatory, to use 
balanced interconnects between your preamplifier and the W-3  when using long cable runs (i.e. 
more than 3 meters in length).   
 
2.  Connect your speakers, with the cables of your choice, to the W-3’s  speaker binding posts. Take 
care to respect the polarity (“+” , “-” ) of the output.  Once again, don’t hesitate to use high quality 
speaker cables.  Poor quality speaker cables can degrade the overall sonic performance of your 
system. 
 
3.  Connect the supplied AC power cable to the IEC receptacle, located on the amplifier’s rear panel. 
Alternatively, if you wish, you may use a dedicated high-performance AC cable designed for high 
current applications.  Ensure that the AC wall outlet you use has a functioning ground.  For the best 
sonic performance, it is preferable that you plug your W-3 directly into a dedicated AC outlet and 
avoid using an extension cord.  If you have the time and willingness, consider installing a superior 
quality AC wall outlet such as a hospital grade Hubbell. 
 
4.  In order to obtain the maximum performance from your audio system, we strongly recommend that 
the detachable power cord not come into physical contact with either the interconnect cables or the 
speaker cables running to and from your W-3.  In the event that this can’t be avoided, you should 
ensure that any cables coming into contact with each other are crossed at ninety degree angles to 
minimize the contact area.
