16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
FEATURES AND BENEFITS
REAL WORLD POWER
The SC16-50 is 16-channel amplier congurable to deliver a solid 50 watts per
channel RMS into 8 ohms or 100 watts per channel RMS into 8 ohms using a
special high power mode. A new digital power transformer design provides the
energy necessary to efciently deliver solid, deep, controlled bass response to
a house full of speakers.
SIXTEEN TO EIGHT CHANNEL IP CONFIGURABLE POWER
Each of the SC16-50’s eight adjacent speaker output pairs are congurable into
a single high power output. You can create up to eight 100 watt channels using
the embedded webserver. This enables you to allocate more power to specic
locations, such as large rooms, outdoor applications or subwoofers.
FREEDOM FROM NOISE AND CROSS-TALK
The SC16-50’s BusMatrix™ incorporates advanced PCB construction ensuring
extremely high channel to channel isolation. Signal to noise ratios and cross-talk
are equivalent to a professional mixing board found in a recording studio.
With the SC16-50, the music playing in the living room cannot interfere with
the music in the den.
TRANSPARENT SOUND
The audio circuitry of the SC16-50 is constructed with the nest parts available,
including metal lm resistors, high quality capacitors and oversized heat sinks.
All this attention to technical detail results in a sound that is clear and uncolored.
IP CONFIGURABLE BUSMATRIX™ SELECTOR
A web based IP Conguration utility provides control of the BusMatrix™ selector
giving you the exibility to assign each speaker channel to any of the sixteen
signal inputs. Adjacent signal input pairs can also be combined and assigned
to a speaker channel for mono sound applications. With BusMatrix™, routing
surround sound to the master bedroom, stereo to the den, mono to the powder
room or high power to a subwoofer has never been easier. BusMatrix™ makes
the SC16-50 an ideal multi-room or multi-zone amplier and offers exciting new
features and system design possibilities to the professional installer.

FEATURES AND BENEFITS CONTINUED...
IP CONFIGURABLE EQ ADJUSTMENT, VOLUME LEVEL
AND HIGH/LOW PASS SELECTION
A web based IP Conguration utility provides independent EQ adjustment and
volume level for each amplier channel enabling you to EQ and set volume
levels for 16 different speakers individually. A High/Low Pass Filter setting for
each channel accommodates passive subwoofers and small full range speakers.
Installers can now acoustically optimize each speaker for both its type and
individual location using a web browser.
TURN-ON MODES
The SC16-50 features three turn-on modes:
1. Manual turn-on via the front panel switch
2. Audio Sense
3. External Voltage trigger.
Audio Sense and External Voltage trigger modes enable you to congure the
SC16-50 to interface with any kind of system and turn on automatically.
AUTOMATIC PROTECTION
Each channel has independent thermal and short circuit protection. In the
unlikely event that a problem occurs on one channel, the other channels will
continue to play. When conditions return to normal, regular operation resumes.
STATUS DISPLAY FOR TROUBLESHOOTING
LED’s on the front panel indicate Power, Active and Protection Status.
With a glance at the front panel a troubleshooter is quickly provided
with key information.

SYSTEM DESIGN BASICS
As shown in Figure 1, a distributed audio/video system is dened by the number
of listening zones it has. Within a listening zone you can listen to only one
source (e.g. CD, Radio, iPod, etc.) at any one time. A listening zone can consist
of a single room or a group of rooms. To achieve different volumes and greater
convenience in different rooms within a zone, individual volume controls can be
used. SpeakerCraft makes volume controls in various styles and colors. When
designing your system, take into account who will use the system and when
they will use it. Consult your local SpeakerCraft dealer for more information.

A MultiZone system as shown in Figure 2, offers the household more exibility.
For instance, a family might have their family room wired for surround sound
and their living room wired for background music. In a two zone system, the
children can watch TV in surround sound while Mom and Dad are reading the
paper and enjoying background music in the living room.

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
SYSTEM DESIGN CONSIDERATIONS
CABLE AND WIRE
Because the SC16-50 has many connections on the rear panel (see page 32 &
33), it is important that you correctly label all of the input cables and speaker
wires. Label the cables and wires with their destination or source, rather than
the SC16-50 terminal to which they are connected. This will make it easier to
recongure your system in the future.
The SC16-50 connects to your sources via shielded line level audio cables with
RCA connectors. Use high quality cables with your SpeakerCraft amplier for
the lowest possible noise and best overall performance. Your SpeakerCraft
dealer can recommend the proper cable.
The SC16-50 connects to your speakers using two conductor speaker wire.
For most applications, we recommend you use 16 or 18 gauge wire. For wiring
runs longer than 80 feet, we recommend 14 gauge wire. The SC16-50’s highquality, gold-plated 5-way binding posts will accommodate up to 12-gauge
wire. Attaching banana plugs to the wire will enable the connection of larger
wire sizes.
USING MONO FOR SMOOTHER COVERAGE
In large or irregularly shaped rooms, you may nd that the main listening area
may be closer to one of the speakers. If the speakers in the room are connected
to a stereo amplier you will only hear half the music.
The SC16-50’s BusMatrix™ enables you to create mono sound from one
speaker without impacting the stereo quality in the rest of the system.
You can congure each amplier channel individually to Left, Right or mono
as needed with no ill effects. Some of the most popular areas where mono
will greatly enhance the sound quality would be:
• Large rooms with many seating areas and/or many pairs of speakers.
• Irregularly shaped rooms.
• Bathrooms with one speaker over the tub and one speaker over the sink(s).
• Hallways or passageways (including those with multiple speakers).
• Small rooms, such as walk-in closets where more than a single speaker
is not required.

SYSTEM DESIGN CONSIDERATIONS CONTINUED...
CREATING HIGH POWER AMPLIFIER CHANNELS FOR
AREAS THAT REQUIRE MORE VOLUME AND POWER
All of the odd numbered amplier channels of the SC16-50 (channels 1, 3, 5,
7, 9, 11, 13, and 15) include a power output of 50 or 100 watts that is selected
using a web based IP Conguration utility. When an odd numbered amplier
channel is congured to 100 watts, it’s even numbered adjacent amplier
channel (e.g. channel 1 and 2, channels 3 and 4, channels 5 and 6, etc.) is
deactivated.
There are several situations where having an SC16-50 channel with more power
is an excellent way to improve the sound. There are also applications where
having an SC16-50 channel with more power would seem to be appropriate but
is not recommended.
These are some of the most common DOs and DON’Ts:
1. Outdoors (DO) — Sound dissipates faster outside than it does in a room
where the walls enclose the sound and reect it back to the listener. A pair of
speakers playing into a large patio or yard will greatly benet from two 100
watt channels.
2. Surround Sound Systems (DO) — The dynamic demands for the center
channel are much greater than the left, right or surround channels. This is an
excellent application for conguring a channel to the 100 watt mode.
3. More than one pair of 8 ohm speakers (DON’T) — In large rooms or long
hallways, often the best way to get good background music is to install
multiple pairs of speakers. You will deliver sound much more reliably using
two pairs of 8 ohm speakers with four 50 watt amplier channels than you
would using two 100 watt amplier channels connected to two pairs of
speakers in parallel.

SPEAKER COMPATIBILITY
Any SC16-50 amplier channel congured to the 50 watt mode is capable of
driving a 4 ohm impedance speaker load. No more than two 8 ohm speakers or
no more than one 4-6 ohm speaker can be safely connected to a single channel.
Proper ventilation of the SC16-50 is critical when driving lower impedance
loads. If the SC16-50 is not properly ventilated, the protection circuits may
activate and shut off the channel at higher volume levels (for more information
on proper amplier placement, see Installation Considerations on page 29).
Any odd numbered SC16-50 amplier channel congured to the 100 watt
mode is capable of driving an impedance load of 8 ohms. Proper ventilation
of the SC16-50 is critical when driving an 8 ohm load with amplier channels
congured to 100 watts. If the SC16-50 is not properly ventilated, the protection
circuits may activate and shut off the channel at higher volume levels (for more
information on proper amplier placement, see Installation Considerations on
page 29).
When designing your system, try to specify 6-8 ohm speakers (SpeakerCraft
offers a complete line of in-wall, in-ceiling, outdoor and home theater
loudspeakers with all models rated from 6-8 ohms).

APPLICATIONS
ADVANTAGES OF USING THE SC16-50 IN
A SINGLE ZONE SYSTEM
When you connect the preamplier outputs of your stereo receiver or stereo
preamplier to the SC16-50 BusMatrix™ you dedicate a robust 50 watts to each
speaker in your multi-room system. (Figure 3)
The SC16-50 has an IP Conguration and Setup tool to adjust volume and tone
for each channel individually so you can compensate for architectural differences
that create sonic imbalances. In addition, you can ne tune the system so that
when all of the room volume controls are set to the loudest level, the large rooms
and the small rooms play at the same volume.

APPLICATIONS
USING A DUAL-ZONE RECEIVER FOR TWO LISTENING ZONES
Most of today’s Audio Video Receivers include a second zone preamplier
output to create a second listening zone. Using this output with the SC16-50
BusMatrix™ input provides amplication for multiple rooms within a second
listening zone as shown in Figure 4.
In addition, in this example high power is supplied to the patio stereo
speakers by conguring channel 13 for high power (left speaker) and
conguring channel 15 for high power (right speaker).

APPLICATIONS
EXPANDING A MULTI-ZONE SYSTEM
TO INCLUDE MORE ROOMS
Many Multi-Zone systems incorporate multiple rooms within a single zone.
The SC16-50 BusMatrix™ Input simplies the connections required for this
system design.
As shown in Figure 5, a SpeakerCraft MRA-664 has its speaker outputs
connected directly to speakers in zones 1-4. The MRA-664’s preamp output ve,
set to a xed output mode, is connected to the SC16-50’s BusMatrix™ inputs.
The BusMatrix™ input signals are then routed to all the amplier channels via
the IP Conguration and Setup Tool. All eight rooms connect to the SC16-50 in
Zone #5 with their own room volume control for adjusting room volume levels
individually.

APPLICATIONS
ADDING PREAMPS TO CREATE MORE LISTENING ZONES
In the ultimate Multi-Zone system, you connect individual stereo preampliers
(or a single component multi-zone/multi-source preamplier) to the BusMatrix™
inputs of SC16-50. These independent input signals are then routed to the
appropriate amplier channels via the IP Conguration and Setup Tool creating
completely independent listening zones.
Multi-Zone systems enable listeners located in the separate zones to
simultaneously listen to different source components as shown in Figure 6.
This example also has the SC16-50’s High/Low Cut output feature setup to
provide satellite speaker amplication (Low Cut from 50 watt channels 13 and 14)
and subwoofer amplication (High Cut from 100 watt channel 15) for zone 7.

INSTALLATION CONSIDERATIONS
TURN-ON MODES
Automating the turn-on of your SC16-50 is one of the easiest steps when
installing it in a distributed system. However, do not plug the main power
cord into the switched AC outlet of your preamplier or receiver. The high
power design of the SC16-50 requires large amounts of current from its
AC power source. Additionally, it is always recommended to activate the
system preamplier/receiver before turning on your SC16-50 in order to
prevent system “turn-on thumps”.
In order to address these important needs, the SC16-50 has three special
turn-on modes that let you turn the amplier on only when it is needed.
Use the Conguration and Setup Tool to access and select one of these
three Turn-On options.
Important! The Front Panel Power Switch must be in the ON (switch in)
position for any of the three turn-on options to function (refer to page 36
for more information concerning the Front Panel Power Switch).
Constant – The auto turn-on circuitry is off. The front panel master power
switch operates the amplier. In is “On”, Out is “Off”.
Audio Sense – The master switch on the front panel must be in the “On”
position. The amplier is off when there is no audio signal present at any of the
audio inputs, but the sensing circuitry is on. The turn-on sensing circuitry looks
for a tiny amount of audio signal present at any of the audio inputs. If it detects
a signal, all the amplier channels will turn on. Once the audio signal stops,
the sensing circuit waits three minutes, then turns all amplier channels off.

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
INSTALLATION CONSIDERATIONS
3-24 VOLT AC/DC OPTO-ISOLATED VOLTAGE TRIGGER - The Power
switch on the front panel must be in the “On” position for the voltage trigger to
function. When a Trigger Plug is inserted into the rear panel connector and the
sensing circuitry detects a voltage, the amplier is turned on. Once the Trigger
voltage is turned off, the sensing circuit instantly turns the amplier off. The
amplier is off when there is no 3-24V AC or DC voltage detected at the trigger
input. Voltage triggers can be suplied by automated switchers, some video
projectors, some surround sound processors, or something as simple as a
12 volt AC wall adapter plugged into the switched outlet of your stereo receiver.
Linear DC wall adapters are not recommended; the long discharge time of the
DC adapter’s lter capacitor will delay the turn-off of the amplier.
Trigger sources must be 3-24VAC or DC, 20mA or greater.
Allow a minimum of 2” of depth behind unit
to accommodate cables and connectors.
If the cabinet rear is not open to fresh air or if
you’re using low impedance loads, install two
“boxer fans” to provide continuous air ow into
and out of the cabinet.
If the cabinet rear is not open to
fresh air, install two small “boxer
fans” to provide continuos air ow
into and out of the cabinet
Make sure that there is a minimum of 5” of free air
space above the amplier and 3” on each side for
proper ventilation.
FIGURE 19 FIGURE 20
Page 30

www.SpeakerCraft.com
INSTALLATION CONSIDERATIONS
PLACEMENT
Place the SC16-50 on a at, level surface like a table or shelf. It should be
placed upright so that its weight rests on the unit’s four feet. PLACING THE
WEIGHT OF THE AMPLIFIER ON THE REAR OR FRONT PANEL FOR EVEN
AN INSTANT WILL RESULT IN DAMAGE TO THE AMPLIFIER’S CONNECTORS
AND CONTROLS.
The SC16-50, like any hi- component, will last much longer if it is given
adequate ventilation for proper cooling. When installing the SC16-50 in a
cabinet, be sure that the rear of the cabinet is open to fresh air to provide proper
cooling (see Figure 19). If the cabinet’s design will not accommodate an open
rear, install two small “boxer fans” to provide continuous air ow into and out
of the cabinet (see Figure 20). Place the SC16-50 so that there is at least 5” of
free air space above the chassis and 3” of space on each side. If the amplier is
located on a carpeted surface, place a board under the amplier’s feet. Do not
block the ventilation holes on the top and bottom of the SC16-50.
Special Notes:
• The SC16-50 is equipped with two internal, thermally activated fans to
assist in the dissipation of heat generated in the amplier section.
The fans are activated automatically based on the demands associated with
the system. These are variable speed fans, the fan speed will also
vary according to these demands associated with the system. Depending
on your installation location (open living area or dedicated equipment closet),
you may be able to hear the fans while in operation. This is a normal function
of the amplier.
• The SC16-50 is equipped with a power transformer. This transformer
generates a powerful magnetic eld which could induce hum in a turntable
(particularly a turntable equipped with a moving coil cartridge).
Do not place a turntable directly above or directly adjacent to the SC16-50.

BUS MATRIX™ LINE LEVEL AUDIO INPUTS
CAUTION! THE AMPLIFIER MUST BE OFF WHENEVER
YOU MAKE CHANGES TO THE INPUT CONNECTIONS.
STEP DESCRIPTION
1. Label all of the interconnecting cables for the sources
they connect to.
Use audio patch cables with RCA phono plugs
attached to the ends.
2. Connect the sources by inserting the RCA
plug into the amplifier’s jacks.
Connect outputs from your sources to inputs on
the amplifier. Never connect a source or
preamplifier’s input (e.g., record inputs) to the
inputs of your SC16-50.
CASCADE AUDIO OUTPUTS
The Cascade Audio Outputs enable you to connect another amplier to
your preamplier output. The connectors are gold-plated RCA phono jacks.
Connect them to another amplier’s inputs with a standard audio patch cable.
The outputs are not buffered.
AC POWER PLUG
STEP DESCRIPTION
1. Plug the female IEC socket of the supplied AC power
cord (the supplied power cord is designed for 120V AC
wall outlets), or use an appropriate IEC AC power cord
to match the electrical wall outlet you are using (e.g.
240V AC), into the IEC receptacle on the rear of the
amplifier. Replace the fuse in the bay below the power
cord inlet with one of the 10A fuses provided if using a
220-240V outlet.
If you use a grounded power strip, surge
suppressor or extension cord, verify that proper
ground is maintained.
CAUTION! Do not plug the amplifier’s cord into a
preamplifier’s convenience outlets.
The SC16-50 draws a maximum of approximately
1600 watts from an AC wall outlet. This is much
more than the typical accessory outlet on the back
of a component will provide. Use the SC16-50’s
auto turn on circuitry to turn on the SC16-50
whenever the preamp is on.

OPERATION
POWER SWITCH
The front panel switch is a master or “vacation” power switch. No matter which
turn-on mode you have selected, the master power switch will turn off all
circuitry including the sensing circuitry. If you will not be using the amplier for
an extended period of time, turn the master power switch “Off” (push button
switch out). When you would like to return to normal operation, turn the switch
“On” (push button switch in).
IMPORTANT NOTES: EQUIPMENT IS NOT COMPLETELY DISCONNECTED FROM
MAIN POWER SOURCE WHEN POWER SWITCH IS IN THE “OFF” POSITION.
POWER LED
The power LED indicates that the AC cord is plugged into a working AC power
receptacle and that the power switch is in the “On” position.
BICOLOR STATUS LED
The bicolor Status LEDs illuminate “green” when the amplier circuitry for the
respective channel has been turned on by the Turn-On circuits, and illuminates
“red” to indicate activation of the amplier channel’s built-in protection circuitry
due to either a fault in the wiring or the speaker, or with the SpeakerCraft
System Integration Amplier® itself.
CLEANING AND MAINTENANCE
The internal parts of the SC16-50 are electronic and require no maintenance.
Once a year it is appropriate to twist the RCA connectors on each input to
remove any oxidation and improve conductivity.
You can clean only with dry cloth. Do not use any spray-type, abrasive cleaners
on the amplier.

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
OPERATION
INPUT LEVEL ADJUSTMENT CONTROL
The rear panel Input Level adjustment screws allow you to adjust the level of
the SpeakerCraft System Integration Amplier relative to other ampliers in your
system and / or to limit maximum safe gain to protect speakers in the system.
Note: Start this adjustment with the Input Level Adjustment Controls at their
factory default. (12:00 position).
For systems that have multiple amplifiers and / or operated by remote
control, i.e. in-wall volume controls, touch pads, etc., use the Input Level
Control to achieve a “maximum” desired listening level across all of the
amplifiers / zones, following these steps:
1. Lower the Input Level Controls to the minimum position. If there are any
other ampliers in the system, lower their respective Input Level Controls
to their minimum (all ampliers in your system must have level controls.)
2. Raise all of the individual in-wall volume controls to their loudest setting.
3. Play a loud radio station with the tuner set to Mono.
4. Raise the volume of your preamplier or receiver SLOWLY – if you hear any
sound, lower the volume and recheck that all of your ampliers Input Level
Controls are turned to their minimum. They must be at their minimums.
Raise the volume again on your preamplier or receiver SLOWLY. If no
sound is heard, proceed to step ve.
5. Have someone step into each room and listen as you adjust each Input
Level Control to the desired maximum level for that room. (Special note:
There is a potential of running the amplier into “clipping distortion” and / or
“protection shut-down” by raising the Input Level Controls to their extreme.
Please review “Listening at Higher Volumes” following this section.)
• In applications with multiple ampliers, step between the different zones /
rooms and adjust the Input Level Controls of each additional amplier to
best match the volume of the rst amplied zone / room.
• With independent Input Level Controls for each channel, volume balance
between speakers within the same room is possible, allowing ne volume
tuning for the most appropriate listening position variables.
Page 38
38
www.SpeakerCraft.com
OPERATION
For systems that are not operated by remote control:
(In-wall volume controls, touch pads, etc.)
Use the Input Level Controls to set a maximum “safe” volume level to protect
your speakers and / or optimize the signal-to-noise ratios between source
components and amplier. Source component output level controls are
sometimes overly-sensitive near their minimum position. By reducing an
amplier’s Input Level Controls, you urge the source component’s volume
control to operate in a more reasonable and enjoyable range. This is very
subjective, so trial adjustments and listening are in order to dial this for the
given application.
As identied in 5b above, with independent Input Level Controls for each
channel, volume balance between speakers within the same room are possible.
This exibility allows for channel volume tuning (left/right channel balance) for
off-center listening positions.
LISTENING AT HIGHER VOLUMES
It requires more power to achieve a reasonable volume of sound in a large room
than it does in a small room. It is possible (even if you are not a teenager) to turn
the volume so high that the amplier runs out of power. This creates “clipping”
distortion.
Clipping distortion can be rst detected in the higher frequencies of your
musical content. Clipping distortion will make the treble sound very harsh and
unmusical. When you hear harsh sounding treble from any good speaker, turn
the volume down immediately! Those harsh sounds are masking some much
more powerful high frequency sound spikes which could quickly damage the
speaker and/or activate the ampliers protection circuit. Clipping distortion
causes the amplier to work harder in its attempt to reproduce the signal
resulting in an increase in heat generated by the amplier.
If you continue to operate the amplier at “clipping” power levels, the amplier
protection circuits will activate when the amplier overheats, shutting the
amplier off. The protection circuits will reset automatically once the amplier’s
internal circuitry cools. Should the protection circuit become activated, reduce
the master volume and re-check the Input Level Control adjustments to
minimize the chance of a reoccurrence. Perpetually overdriving your speakers
and amplier is considered abuse and will void the manufacturer’s warranty of
all affected products.

TROUBLE-SHOOTING GUIDE
When there is a problem consult this guide rst. If the problem persists, or you
have additional questions, call your local SpeakerCraft dealer or call SpeakerCraft
Technical Support at 1-800-472-5555. The most common problems relate to hook
up. Have your conguration worksheet handy when you call.
Symptom Possible Causes and Test Procedure
No sound on one
channel
Short circuit or loose wire at speaker or amplifier terminals. Check that connections are secure
and that there are no loose strands of wire crossing from the positive to the negative terminal
at the back of the amplifier and the speaker.
Short circuit or a break in the speaker wire. Disconnect the speaker wire at both ends, separate
the 2 conductors at both ends and test with a meter for a short circuit. If there is no short,
connect the two conductors at one end and test with a meter for continuity.
Speaker is not working. Connect the speaker to a channel that plays another speaker. Audio
cable to dedicated input is bad. Connect the non-working channel input to another cable that is
known to be good.
Adjacent channel set to High Power Mode. Check your configuration worksheet for the correct
setting and verify. The thermal protection circuit has operated because of overheating caused
by overdriving or inadequate ventilation. Check front panel status LEDs.
No sound on some or
all channels
Check your configuration worksheet and verify all settings.
Audio cable to the inputs is bad. Connect the nonworking channel input to another cable that is
known to be good. Some or all of the internal amplifier fuses are blown. (Return the amplifier to
your dealer for service).
Hum from all the
speakers
Hum may be caused by a ground loop between two components in the system. Test for a
ground loop by reversing the AC plugs of any components in the system with non polarized AC
plugs.
Check for faulty cables, faulty source material, an ungrounded phono system, cable TV feed or
a defective component.
Amp will not turn on
Master power switch must be on.
AC power cord must be plugged into a working outlet.
Test that the AC power receptacle is working. If the outlet tests O.K., the internal fuses are
blown. Return the amplifier to your dealer for service.

LIMITED WARRANTY
Core Brands, LLC (“Core Brands”) warrants to the original retail purchaser only that this product will be free of manufacturing
defects in material and workmanship for the following periods and subject to the limitations and exclusions set forth below:
Two years from the date of purchase
This warranty is not transferable to subsequent purchasers of the product. To obtain warranty service, contact the authorized dealer
where you purchased your product or take the unit to the nearest authorized SpeakerCraft dealer (with proof of purchase – claims
made without proof of purchase will be denied) who will test the product and if necessary, forward it to Core Brands for service. If
there are no authorized SpeakerCraft dealers in your area, you must contact Core Brands to receive a factory Return Authorization
Number. DO NOT RETURN ANY UNIT WITHOUT FIRST RECEIVING WRITTEN AUTHORIZATION AND SHIPPING INSTRUCTIONS
FROM CORE BRANDS.
Upon examination, Core Brands will, at its sole option and expense, repair or replace any product found to be defective. Core
Brands will return the repaired or replaced unit to you via its usual shipping method from the factory to your address in the
United States of America or Canada only. Any shipping costs for addresses outside of the United States or Canada shall be the
responsibility of the purchaser. In the event that this model is no longer available and cannot be repaired effectively, Core Brands, at
its sole option, may replace it with a different model of equal or greater value, or refund the original purchase price paid.
THE FOREGOING ARE YOUR EXCLUSIVE REMEDIES FOR BREACH OF WARRANTY.
This Warranty does not include service or parts to repair damage caused by improper use or handling, including but not limited to
damage caused by accident, mishandling, improper installation, commercial use, abuse, negligence, or any defect caused by repair
to the product by anyone other than Core Brands.
This warranty does not cover reimbursement for your costs of removing and transporting the product for warranty service
evaluation, or installation of any replacement product provided under this warranty.
This Warranty will be void if:
•the Serial Number on the product has been removed, tampered with or defaced.
• the product was not purchased from an authorized dealer or reseller.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESSED AND IMPLIED WARRANTIES.
CORE BRANDS EXPRESSLY DISCLAIMS ALL SUCH OTHER WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT, WITH RESPECT
TO THE PRODUCT. TO THE MAXIMUM EXTENT PERMITTED BY LAW, SPEAKERCRAFT SHALL NOT BE RESPONSIBLE
FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES EXCEPT TO THE EXTENT PROVIDED (OR PROHIBITED) BY
APPLICABLE LAW, EVEN IF CORE BRANDS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Notwithstanding the above, if you qualify as a “consumer” under the Magnuson-Moss Warranty Act, or applicable state laws, then
you may be entitled to any implied warranties allowed by law for the Warranty Period. Further, some states do not allow limitations
on how long an implied warranty lasts or allow the exclusion or limitation of consequential damages, so such limitations may not
apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
