To use the high-pass outputs, connect
the preamp outs on your preamp/
receiver to the subwoofer’s line level in-
puts using good quality RCA type patch
cords. Then connect a second patch
cord from the subwoofer’s outputs to
the inputs of your main amplifi er. This
will allow your main speak ers to oper-
ate at fre quen cies above 70 Hz and the
sub woof er to operate at fre quen cies
below 70 Hz (see page 13).
5. Line-Level Inputs
Connect these unbalanced inputs with
RCA type patch cords to the line-level
outputs of your receiver or preamp.
If your preamplifi er or receiver has a
single sub/LFE output, connect it to
the sub woof er’s left input jack (see
page 11). There is no need to use the
subwoofer’s right input jack.
If you want to run your main/satellite
speakers full range, use a “Y” adapter
at the preamplifi er outputs (see page
12). In this way, you can send the
preamplifi er’s output signal to your
main amplifi er and to the subwoofer at
the same time.
6. Speaker-Level Inputs
Under normal conditions, the preferred
connection is through the line-level
inputs. If this is diffi cult or not possible
in your system, then you can use the
speaker-level inputs. Also, if you ex pe -
ri ence ex ces sive noise or hum with the
line-level inputs, often a simple change
to the speaker-level inputs will result in
a lower back ground noise level.
Connect the speaker-level inputs to the
speak er-level outputs of your am pli fi er
or receiver using speaker wire. The
binding posts can accept bare wire,
banana, dual-banana or spade con-
nec tions.
Your amplifi er or receiver MUST
have com mon grounded outputs,
or it will be dam aged if con nect ed
to the subwoofer’s speaker-level
inputs.
7. Line Fuse
The subwoofer is supplied with a con-
ser va tive 4 amp slow-blow type fuse to
protect the elec tron ics.
Always unplug the power cord
before inspecting or changing
the fuse. Never use a fuse with a
larger current rating than 4 amps.
8. IEC Linecord socket
The Sunfi re Subwoofer comes with a
detachable linecord which connects
here.
Connect the linecord to the
subwoofer before connecting the
other end to an 120 Volt, 60 Hz
AC outlet. The outlet must have
a cir cuit rating of 8 amps or more
(a typical home circuit is rated at 15
amps).
If you live in or move to a country
where the power grid is 220-240 Volts,
the subwoofer must be plugged into a
step-down trans form er that is rated at
500 watts or more.
Never plug the subwoofer directly
into 220-240 Volts AC as this will
cause cat a stroph ic circuit failure.
9. Power/Auto on In di ca tor
This light is bright when the sub woof er
is on, and dim when the sub woof er is
in its stand by mode. This is con trolled
by the AUTO ON/OFF circuit. The pres-
ence of an audio signal turns the unit
on. After ap prox i mate ly fi fteen min utes
of signal absence, the sub woof er will
go to its stand by mode.
The light will only go com plete ly off
when the unit is unplugged from the
wall.
