Troubleshooting - Proficient Audio Systems PS12 Owner's Manual

INSTALLATION
Voltage Selector (See Figure 1)
For use in the U.S., the PS12 / PS10 / PS8 comes preset from the factory at 115V. For use in other coun-
tries, the voltage may be set at 230V. (Please note that an outlet adapter or alternate power cord may be
required.)
Connecting the LFE and Line Level Audio Inputs (See Figure 2)
If your surround sound receiver or amplifier has a dedicated subwoofer output, simply plug it into the
LFE. If your receiver or amplifier has a built-in preamplifier, the left and right pre-outputs can be con-
nected to the Left and Right Line Inputs. CAUTION: Only make connections when the PS12 / PS10 / PS8 is
turned off.
OPERATION
Once the PS12 / PS10 / PS8 is connected, use the controls described below to make adjustments so that it
will blend seamlessly with the other speakers in your system.
Phase Switch (See Figure 3)
Depending upon the placement of the Subwoofer, relative to the Main Speakers, the Phase Switch
may need to be in the 0 or 180 position to facilitate the most seamless acoustic blend. Playing a variety
of music, listen to the system, at the main listening position, with the switch in both positions, choose the
one that yields the most pleasing results.
Power Switch (See Figure 3)
This switch sets the power mode of the PS12 / PS10 / PS8. Select "On" or "Off" to turn the system on or
off. Selecting "Auto" will automatically turn the PS12 / PS10 / PS8 on when it receives an audio signal from
your system. The subwoofer will automatically turn off when it stops receiving the audio signal.
Crossover Knob (See Figure 3)
Use this control to adjust the upper frequency limit of the PS12 / PS10 / PS8, to control the overlap of the
upper frequencies of the PS12/ PS10 / PS8 and the main speaker's lower frequencies.
Volume (PS12), (PS10) / Level (PS8) Knob (See Figure 3)
Use this control to match the output of the PS12 / PS10 / PS8 to that of the main speakers in the
system. We recommend that you play a variety of material before selecting a setting. Start with the con-
trol in the "Min" position (completely counterclockwise) and slowly turn it up.
