Introduction
Thank you for purchasing a Sunre
High Resolution Series Subwoofer. We
hope you enjoy it and the music it makes
as much as we have enjoyed creating it
for you.
The big breakthrough features of the
subwoofer are its uncanny 1,000W Track-
ing Downconverter amplier, and its long
throw, High Back-emf woofer. These
powerful forces combine to produce as
much bass as several 15 inch drivers
mounted in a cabinet the size of a small
refrigerator! And, the High Resolution
Series' extended frequency response
means that your subwoofer is the perfect
match to virtually any loudspeaker.
Unpacking
Your Sunre subwoofer should reach
you in perfect condition. If you do notice
any shipping damage, please contact
your Sunre Dealer immediately.
Gently lift out the unit and remove all
the packing material. It is important to
save all the packing materials and the
box in case your subwoofer ever needs
to be moved or shipped for repair.
Make sure that you keep your sales
receipt. It is the only way to establish
the duration of your Limited Warranty
and it may come in useful for insurance
purposes.
Please take a moment to ll out and
mail the Sunre Customer Response
card. Also read the serial number located
on the control panel and record it here:

User's Manual
Overview
The Sunre HRS subwoofers are
designed to give you the best possible
low-frequency sound quality for your
Home Theater and music playback experience. They incorporate a tremendously
powerful built-in amplier to produce
tight, seismic, denture-rumbling bass that
you can feel as well as hear.
There are three models in the high
resolution series: the HRS-8, HRS-10,
and the HRS-12. (The number represents
the driver diameter in inches.) The control
panel, connections and operation are the
same for each subwoofer model, and this
manual covers all three models.
Each subwoofer has controls for adjusting the crossover frequency, phase, and
volume. They also have line-level and
speaker-level inputs for easy incorporation into existing systems, or as part of a
subwoofer/satellite speaker combination.
The Driver
To have lots of bass requires the movement of lots of air. To achieve this, the
subwoofer's driver has been designed to
travel back and forth approximately ve
times further than a normal driver. This
gives lots of air movement and massive
bass performance.
If the input signal is driven even further,
a ‘soft clipping’ circuit is enabled. This
allows the driver to put more sound into
the room to satiate the power hungry
user, but without distortion or damage to
the driver. This produces extremely high
sound pressure levels (SPL) in your room
without the driver banging against its
mechanical stops.
Sub/LFE
In this manual, the term “Sub/LFE” is
used to denote the subwoofer or Low
Frequency Effects output, commonly
found on Home Theater processors and
receivers.
The Tracking Downconverter
Amplier
The large movement range of the driver
generates greater air pressure inside the
box than a conventional driver. In order
to create this range of movement, we
designed a drive amplier that is much
more powerful than an ordinary amplier.
A signal compressor circuit kicks in
automatically if the input signal level
reaches a level that would overload the
driver. This maintains a ceiling on the
output without clipping.

1. Power Indicator
This light is bright when the subwoofer
is on, and dim when the subwoofer is in
standby mode.
2. Power Switch
Press the top of this rocker switch to
turn on the subwoofer.
The subwoofer has an automatic
signal-detection circuit. After approxi-
mately fteen minutes with no signal,
the subwoofer will go into its quiet
standby mode. The presence of an
audio signal will turn it back on.
Normally you can leave the switch on,
and let the subwoofer turn on when a
signal is present, or off when it's not.
At night, or if you go out, or on vaca-
tion, you can press the bottom of the
power switch to turn the subwoofer off.
3. IEC Power Connector
The subwoofer comes with a detach-
able linecord that attaches here. Make
sure it is rmly pushed into place.
Connect the other end to an AC outlet
that is properly congured for the type
of plug and has the correct voltage for
your model.
6
4. AC Line Fuse
The subwoofer is supplied with a
conservative slow-blow type fuse to
protect the electronics. If this fuse fails,
replace it with the exact same type and
current rating for your local AC voltage,
as marked on the control panel near
the fuse holder.
Note: Always unplug the power
cord from your AC outlet before
removing the fuse. To replace or
inspect the fuse, use a small at-
ended screwdriver to gently pry out the
fuse carrier and fuse.
5. Speaker-Level Inputs
If you are using a receiver which only
has speaker-level outputs, you can
connect it using the speaker-level
inputs (see the hookup diagram on
page 14). They can accept bare wire,
banana, or dual-banana connectors.
If you experience excessive noise or
hum using the line-level inputs, try using the speaker-level inputs. This may
lower the background noise level.
