To use the high-pass outputs, connect
the preamp outs on your preamp/
receiver to the subwoofer’s line level
inputs using good quality RCA type
patch cords. Then connect a second
patch cord from the subwoofer’s
outputs to the inputs of your main
amplifier. This will allow your main
speakers to operate at frequencies
above 70 Hz and the subwoofer to
operate at frequencies below 70 Hz
(see page 13).
5. Line Level Inputs
Connect with RCA type patch cords to
the line level outputs of your receiver
or preamp.
If your preamplifier or receiver has a
single sub/LFE output, connect it to the
subwoofer’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 preamplifier outputs (see page
12). In this way, you can send the
preamplifier’s output signal to your
main amplifier 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 difficult or not possible
in your system, then you can use the
Speaker Level inputs. Also, if you
experience excessive noise or hum
with the Line Level inputs, often a
simple change to the Speaker Level
inputs will result in a lower background
noise level.
Connect the Speaker Level inputs to
the speaker-level outputs of your
amplifier or receiver using speaker
wire. The binding posts can accept
bare wire, banana, dual-banana or
spade connections.
Your amplifier or receiver MUST
have common grounded outputs,
or it will be damaged if connected
to the subwoofer’s Speaker Level
inputs.
7. Line Fuse
The subwoofer is supplied with a
conservative 4 amp slow-blow type
fuse to protect the electronics.
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 Sunfire 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
circuit 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 transformer that is rated at
500 watts or more.
Never plug the subwoofer directly
into 220-240 Volts AC as this will
cause catastrophic circuit failure.
9. Power/Auto on Indicator
This light is bright when the subwoofer
is on, and dim when the subwoofer is
in its standby mode. This is controlled
by the AUTO ON/OFF circuit. The
presence of an audio signal turns the
unit on. After approximately fifteen
minutes of signal absence, the
subwoofer will go to its standby mode.
The light will only go completely off
when the unit is unplugged from the
wall.
