sunfire hrs 系列建意使用方法: Connections to a preamplifier’s subwoofer output
If your processor or receiver has
a subwoofer output (Sub/LFE), it
should be connected to the subwoofer’s
Left input as shown. This
is the simplest and recommended
connection.
If you have a Home Theater processor
or receiver, it probably has
an independent subwoofer volume
and crossover control. If so, you
should set the subwoofer’s volume
control to 0 dB, the crossover to
Bypass, and use the processor’s
subwoofer level and frequency controls
for adjustments.
Connections using Y cables
If your processor does not have
a Sub/LFE output, you can use
“Y” cables (or Y adaptors) to send
its left and right main outputs
to both the subwoofer and your
amplifier.
The subwoofer will play the low
frequency range, and your front
speakers will play the full range.
Although bass is commonly
distributed evenly between left
and right channels (L+R bass),
movie soundtracks often contain
differential (L-R) bass. If this is
not preserved, the bass
in these scenes
sounds anemic. The
subwoofer utilizes
differential gain on
the left and right
inputs to retain both
the L+R and L-R
information.
Systems that do
not have a dedicated
Sub/LFE output
should use both
the left and the right
inputs as shown, for
the greatest bass impact
Using the line-level high-pass outputs
If you are using a receiver or
processor which does not have
a Sub/LFE output, you can send
its left and right front output
into the subwoofer’s Line-Level
inputs and then connect the
subwoofer’s High-Pass outputs
to the inputs of your amplifier.
The subwoofer will play the
low frequencies, and your
amplifier and front speakers
will play the frequency range
above the subwoofer’s fixed
(70 Hz) high-pass crossover
point.
The signals coming
out of the subwoofer’s
high-pass
outputs are not
affected by any of
the controls. They
are just a copy of
the signals going
into the subwoofer
except that the
low bass is filtered
out. This uses
the subwoofer’s
passive crossover
network, set at 70
Hz, rather than the
active network and other controls.
This is an excellent method if your
speakers are small satellites or minimonitors,
and/or your power amplifier is
of limited power, such as a tube amp.
For the ultimate in computer sound
systems, connect the left and right audio
output from your computer sound card
into the subwoofer inputs. Connect the
sub's high-pass outputs to the inputs of
your powered speakers. You may need
some RCA-to-mini plug adaptors to make
the connections. Adjust the sub's volume
control to match low-powered speakers.
