The PSB subwoofer includes
designed-in dynamic-range
protection: IT is virtually impossible
to overdrive the subwoofer,
regardless of volume setting or the
demands of the program material.
Where even higher levels of low
frequencies are required, a second
PSB subwoofer can provide a
significant gain in total bass levels.
Adjusts the output level of the
PSB subwoofer only: This is
not intended as a day-to-day
volume control. See "VII. Setup
Calibration"

B. ON INDICATOR LIGHT
The light is located between the
control knobs. WITh both the 120
and 230 vo~ versions, the
subwoofer is initially in stand-by
mode awaITing the presence of an
audio signal. When the subwoofer
receives an audio signal the On
indicator will illuminate. At the end
of the audio signal the subwoofer
will stay on for approximately 15
minutes.
C. AC POWER CONNECTION
E. HIGH/SPEAKE LEVEL TERMINALS
Connect the PSB subwoofer to
receivers or integrated amplifiers
equipped with speaker outputs
only. See "VI. Connecting The
Subwoofer to Your Audio
System".
F. AC POWER SOCKET
Supplies AC power to the PSB
subwoofer Connect the supplied power
cord to the AC power socket. Plug the
power cord into any standard wall
outlet. With 230 vo~ versions, in some
countries it may be necessary to
replace the power cord to meet the
standards in use locally. The same
receptacle as the rest of the system or
another on the same electrical cirCUIT
should be used to avoid ground hum.
The PSB subwoofer has its own self-contained amplifier and thus requires AC power (keep this in mind
when selecting a location). You may plug the power cord into any standard wall outlet and leave the
connection in the wall as the PSB subwoofer draws extremely little current when idle. You may want to
unplug your PSB subwoofer when it will not be used for an extended period such as a vacation.
