Warranty

Sunre, a division of Elan Home Systems,

LLC, is proud of its products which have been

built with care using advanced technology and

premium component parts. Your unit has been

crafted to perform properly for many years. The

warranty details for your product are shown on

the sunre website.

Introduction

Thank you for purchasing a Sunre Dynamic

Series Subwoofer. We hope you enjoy it and

the music it makes as much as we have en-

joyed creating it for you.

The big features of the subwoofer are its

high-efciency Class D digital amplier, and

its computer-optimized woofer and passive

radiator design. 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 Sunre Dynamic Series'

extended frequency response means that your

subwoofer is the perfect match to virtually any

loudspeaker. The result is extraordinarily high

operating efciency – that is, more acoustic

output for each watt of input.

Unpacking

Your Sunre subwoofer should reach you in

perfect condition. If you do notice any shipping

damage, please contact your Sunre 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.

Important Safety Instructions

12. Use only with the cart stand

tripod bracket or table speci-

ed by the manufacturer or

sold with the apparatus.

When a cart is used use cau-

tion when moving the cart/ap-

paratus combination to avoid

injury from tip-over.

13. Unplug this apparatus during Iightning storms

or when unused for long periods of time.

14. Refer all servicing to qualied service person-

nel. Servicing is required when the appa-

ratus has been damaged in any way such

as power-supply cord or plug is damaged,

liquid has been spilled or objects have fallen

into the apparatus, the apparatus has been

exposed to rain or moisture, does not operate

normally, or has been dropped.

15. This apparatus has been equipped with a

rocker-style AC mains power switch. This

switch is located on the rear panel and should

remain readily accessible to the user.

16. The mains plug or an appliance coupler is

used as the disconnect device, so the discon-

nect device shall remain readily operable.

WARNING

To reduce the risk of re or electric shock, do not

expose this apparatus to rain or moisture.

Location

Your SDS Subwoofer is designed to be placed

in a corner for optimum performance.

Experiment with at least two corners and de-

cide which sounds the best.

Although low frequencies are non-directional,

room reections, standing waves, resonance

and absorption strongly affect the performance.

Moving the subwoofer from one corner to

another can have a major effect on the bass

response.

Keep it at least two or three feet away from any

CRT screen, computer, VCR or magnetic tapes

and discs. This will reduce the chance of the

magnetic elds upsetting the CRT screen or

erasing your magnetic media.

Also position the control panel so that it is

not touching anything and can receive good

ventilation.

Using Two Subwoofers

With two subwoofers, the sound output will

double. Place each subwoofer in a corner, and

experiment with the location and phase control

to achieve the best bass response.

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install

in accordance with the manufacturer’s in-

structions.

8. Do not install near any heat sources such

as radiators, heat registers, stoves or other

apparatus (including ampliers) that produce

heat.

9. Do not defeat the safety purpose of the polar-

ized or grounding type plug. A polarized plug

has two blades with one wider than the other.

A grounding type plug has two blades and a

third grounding prong. The wide blade or the

third prong are provided for your safety. If the

provided plug does not t into your outlet,

consult an electrician for replacement of the

obsolete outlet.

10. Protect the power cord from being walked on

or pinched, particularly at plugs, convenience

receptacles, and the point where they exit

from the apparatus.

11. Only use attachments/accessories specied

by the manufacturer.

1. AC Input Connector

Connect the supplied linecord here.

2. Power Switch

Turns the subwoofer on or off.

3. Line-Level Inputs

These connect with RCA cables

from the sub/LFE line-level

output(s) of the receiver or preamp.

If there is only one output, use the

left input jack.

4. High-Pass Outputs

These outputs are a copy of the

signals going into the inputs,

except the bass has been removed

by a xed high-pass crossover

circuit. The output is not affected by

the subwoofer’s controls.

5. Turn-On Mode

Signal Sense

The subwoofer will unmute when

an audio input signal is present

at the inputs. After approximately

fteen minutes with no signal, the

subwoofer will mute.

Always On

The subwoofer is unmuted and

ready to play when the power

switch is on.

6. Power Status Indicator

This light is green when the sub-

woofer is on and unmuted, and red

when the subwoofer is muted in

standby mode.

7. Crossover Frequency

This controls the crossover fre-

quency between 50 Hz and 150

Hz. If it is set to 100 Hz for exam-

ple, the subwoofer will reproduce

the frequency range below 100

Hz. Rotate the control clockwise to

increase this frequency range up to

150 Hz.

Select BYPASS if your system

has its own crossover frequency

control.

If your processor does not have its

own subwoofer crossover fre-

quency control, rotate this control

until the bass sounds natural. If

the mid-bass sounds natural but

you want more low bass, turn the

crossover frequency down a little,

then turn the volume up by about

the same amount. This increases

the low-bass output while leaving

the mid-bass output the same.

8. Phase

This controls the relative phase of

the subwoofer with respect to your

other speakers. Use this to help

blend the subwoofer with the rest

of your system.

Adjust the control in small incre-

ments as you listen for the most

bass at your listening position. As

a nal trim, readjust the crossover

frequency and volume controls af-

ter the phase control has been set.

9. Volume

This control lets you match the

output level of the subwoofer to the

level of your other speakers. When

installing your system, turn this

down rst before turning on your

subwoofer, to prevent any loud

surprises.

Adjustments

There are two main methods for adjusting the

volume, crossover frequency and phase con-

trols to match a system:

• Preferred method: By listening and mak-

ing the adjustments to suit your taste.

• Laboratory method: By measuring the

output with a microphone and adjusting

for a at frequency response.

Excellent results can be obtained if you make

the adjustments based on simply listening. This

is our preferred method as it allows the system

to be voiced based on what sounds the best,

whereas laboratory-at frequency response

can often be clinical and less than exciting.

Connections

Please consider the following when setting up

your new system:

• Before making or changing any

connections, always make sure that the

subwoofer and your other components

are turned OFF. Turn down the volume

control of both the subwoofer and your

processor or receiver.

• Route power cords away from the signal

cables or speaker wires to prevent hum

or interference.

• Choose reliable, high quality interconnect

cables. They should be fully shielded

and as short as possible for the job. The

longest cable in your system will likely

be to the subwoofer, so choose a good

quality brand.

Wireless Option

A optional wireless kit is available that will allow

the subwoofer(s) to receive audio input without

the need for long cable runs. Please contact

your Sunre dealer for details.

1. Turn off the subwoofer and receiver

power before making connections.

2. Connect receiver’s Sub/LFE line-level

output to the subwoofer’s L/LFE input.

3. Set subwoofer’s crossover frequency

control to BYPASS, volume control to

0 dB, and phase control to 0 degrees.

4. Use the receiver’s subwoofer controls to

adjust the frequency range and volume.

5. Alternatively, the subwoofer’s crossover

frequency, volume, and phase can be

adjusted carefully to blend the subwoofer

into your system.
