First, turn off power to your entire system to prevent accidents 
such as short circuits from damaging your equipment. 
The PSW112 subwoofer can be connected to your system using 
one of three methods. The method you select is based on the 
configuration of your system. 
1.  Amplifier with a subwoofer output connection – If your 
system has a subwoofer output connection, use an RCA 
type connector to connect the PSW112 subwoofer to your 
receiver. A shielded audio cable is required for this setup 
with a Y-adapter connecting the audio cable to Left and 
Right Line Level Input on the subwoofer. 
2.  Separate pre-amp/power amp configuration – When 
using a separate pre-amplifier/power amplifier the audio 
cables may be routed through the PSW112 subwoofer unit. 
Connect the pre-amplifier to the Line Level Inputs via RCA 
cables and connect the Line Level Outputs to the power 
amplifier.  
Connecting Your Subwoofer Subwoofer Controls 
Your PSW112 subwoofer has 
several controls that allow you 
to configure the unit to reflect your personal music tastes. All 
controls are found on the back of the unit. 
v Frequency Adjust – This adjusts the upper 
frequency range of the subwoofer. A typical setting 
when using the subwoofer with the MNCX Platinum 
Mini-Cube speakers is between 120Hz to 140Hz. 
v Auto Power – The subwoofer can be set up with 
two different power configurations: 
o Auto Power On –
 The subwoofer will power 
down a few minutes after the signal is 
removed and it will turn on immediately 
when it receives a signal. 
o Auto Power Off – The subwoofer is 
constantly on if the unit is powered up. 
v Volume Control – The volume control should be 
set to the desired bass level for the system. 
v Phase – The Phase switch is set for the best bass 
sound. Switch between the 0 and 180 position until 
the bass is the loudest. In some applications, there 
may be no noticeable difference and in this case 
leave the switch in the 0 position.
