Connecting Stereo Equipment With High/Speaker Level; Using Multiple Subwoofers; Set-Up Calibration - PSB Speakers PSB Sub 500 Serie Manual De Propietario

you are using a separate preamplifier, the preferred connection is
from the eamplifier Output of the electronics to the Low Level Input
of the subwoofer. Use a dual RCA audio cable and maintain right
and left. (You may need to use Y-connectors at the preamplifier
outputs to also send signals to the Power Amplifier/Main Inputs.
Connecting the Low/Line Level Outputs from the subwoofer back to
the Power Amplifier Input is an important option. The Low/Line Level
Inputs of the subwoofer are internally processed through an active
high pass filter (at 12dB/octave below 80Hz) to the Low/Line Level
Outputs of the subwoofer. Connecting the Low/Line Level Outputs
from the subwoofer back to the Power Amplifier Inputs delivers the
processed signal, with reduced low frequency content, to the main
speakers. With less low frequency demands, the main speakers can
play louder. Particularly with smaller and/or less efficient main
speakers, relieving speakers other than the subwoofer of the
demands of reproducing low frequencies will allow greater sound
output and dynamic capabilities from the other speakers and from
the system overall.
C. Connecting Stereo Equipment With High/Speaker Level (see
Figure 5, page 21):
You also can get excellent sonic results by connecting the
High/Speaker Level Output of your receiver, integrated amplifier or
power amplifier to the High Level Input of the subwoofer. Use
standard speaker cable and maintain polarity + , as well as right and
left side.
D. Using Multiple Subwoofers (see Figure 6, page 22):
Particularly in difficult rooms with difficult layouts, using two
subwoofers is an alternative to smooth, as well as increase bass
response. One subwoofer can be located to increase response, with
the second subwoofer located to smooth response. The wiring of
two subs in a system is illustrated in Figure 6 (the two subs do not
need to be identical). Please refer to Section V, Multiple Subwoofers
for further information.
IX. Set-up Calibration
The following procedure assumes your PSB subwoofer is installed and
connected. If possible, work in a team with another person: one listening,
one making subwoofer-control adjustments.
A. Set Sub Volume to 0, Sub Cut-Off Frequency to 50Hz and Phase to
0°. Set any loudness, bass and treble, and/or equalizer controls on
your preamplifier or integrated amplifier or receiver, or other
components, to their nominal (midpoint or off) positions.
B. Play a familiar compact disc, LP, or video soundtrack that includes
