Connecting the
Low/Line Level Outputs
from the subwoofer back to the
Power Amplifier Inputs
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 sub-
woofer back to the
Power Amplifier Inputs
delivers the processed sig-
nal, 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.

Connecting Stereo Equipment with High/Speaker Level (SEE FIGURE
5, page 18):
You also can get excellent sonic results by connecting the
High/Speaker Level Outputs
of your receiver, integrated amplifier or
power amplifier to the
High/Speaker Level Inputs
of the subwoofer. Use
standard speaker cable and maintain polarity, as well as right and left.
High/Speaker Level Outputs
from the subwoofer allow speaker wires
to be run onwards easily from the subwoofer directly to the main
speakers. The signals from the SubSonic 5
i to the main speakers are
looped through, full-range. This replaces running from the receiver or
amplifier to the main speakers. The
High/Speaker Level Inputs
of the
SubSonic 6
i are internally processed through a passive high pass filter
(at 6dB/octave below 100Hz) to the
Speaker Level Outputs
of the sub-
woofer. Connecting the
Speaker Level Outputs
from the subwoofer
directly to the main speakers delivers the processed signal, with
reduced low frequency content. With less low frequency demands, the
main speakers can play louder.
D. Using Multiple Subwoofers (SEE FIGURE 6, page 19)
Particularly in difficult rooms with difficult layouts, using two subwoofers
is an alternative to smooth, as well as increase bass response. One sub-
woofer can be located to increase response, with the second subwoofer
located to smooth response. The wiring of two subs in a system is illus-
trated in Figure 6 (the two subs do not need to be identical). Please refer
to Section V, Multiple Subwoofers for further information.

SET-UP CALIBRATION
The following procedure assumes your PSB subwoofer is installed and connect-
ed. If possible, work in a team with another person: one listening, one making
subwoofer-control adjustments.
