Speaker Level Connections
Plug in the PSW112 power cord. Do not plug the PSW112
subwoofer into a switched outlet on your receiver. The
PSW112 has an automatic stand-by circuit to ensure prompt
power up and connecting the unit to a switched outlet will
delay the output and lead to noise on power down.
