CONNECTIONS

2.1 SPEAKER CONNECTIONS

Depending on the level of the input signal, the voltage at the outputs can be high enough to cause electric

shock – be sure that power is turned o when connecting or disconnecting anything. As well, be sure that the
speakers are rated for use with this amplier – an overdriven speaker can pose a re hazard.

Connect the red (+) connection on the speaker to the red (+) binding post on the amplier, and the black (–) connection on
the speaker to the black (–) binding post on the amplier using cable that is insulated to handle the maximum output of the
amplier. Do not overtighten the binding posts as this may cause damage. The binding post pair accepts a connection from

one speaker.

2.2 DIGITAL INPUT CONNECTIONS

Stereo digital audio sources can be connected using AES/EBU, coaxial or optical cable. The PCM stereo format up to
24-bit / 192 kHz is supported by all digital inputs. If using sources that have an option for selecting between PCM and

Bitstream or Dolby Digital audio output, select PCM.

A personal computer can also be connected to the asynchronous USB DAC input. Stereo PCM up to 32-bit / 384 kHz, and
DSD format up to 5.6 MHz are supported through this connection. Simply connect your computer and use media playing
software on it to have music playing through your system. If using a Windows PC, the USB DAC driver must rst be
downloaded from our web site and installed. With Mac OS, just plug and play.

2.3 ANALOG CONNECTIONS

Balanced XLR connection oers the highest analog transmission quality, particularly over long cable lengths because it
rejects noise and hum pickup. One such input is provided using the conventional pin-2 positive conguration. There are

also four RCA line inputs.

For phono, there are two inputs. Be sure to use the correct one otherwise level will be aected and treble response may be

altered. The MM input is suitable for turntables using moving-magnet and high-output moving-coil phono cartridges. The
MC input uses input impedance and gain tailored to low-output moving-coil cartridges. As well, connect the ground wire
from the turntable to the screw terminal next to the phono inputs to prevent excessive hum.

The subwoofer jacks are labelled “L” and “R” but if the system uses one subwoofer, it can be connected to any subwoofer

output jack.

2.4 LOCAL AREA NETWORK

A network connection is required for conguring Anthem Room Correction or using IP control. Simply connect your router

using CAT5 cable.

2.5 12 VOLT TRIGGER

If another system component has a trigger input it can be activated by the STR Integrated Amplier. Connect the STR
Integrated Amplier’s trigger output using a cable with 3.5mm mini plugs. The STR Integrated Amplier provides exible

trigger options. Through the setup menu, you can specify the conditions for enabling triggers.

2.6 INFRA RED

An external IR receiver allows the remote control to be used from another location in your home – connect the STR
Integrated Amplier from an external IR hub to the IR IN jack. Most standard IR repeater kits can be used but to avoid

problems test compatibility before installing permanently.

2.7 POWER

Connect the power cord to the STR Integrated Amplier and the power source.

5

SETUP

For optimum performance and enjoyment, your STR Integrated should be properly set up. This might seem like a lot of
work at rst because of the number of menu options, but most settings do not need to be changed from the defaults.

The important ones relate to your input connections and speakers. If you’re using a subwoofer or subwoofers, Anthem
Room Correction will set crossovers and levels for a perfect blend with the main speakers. The rest of the settings
mostly relate to your preferences.

HOW TO NAVIGATE IN THE SETUP MENU

3.1 SPEAKER SETUP

Normally only one speaker conguration is needed but more are provided for instant recall of stored subwoofer
or Anthem Room Correction settings.

If you will be using the personal computer version of ARC, you can skip this menu since it will be set while the program
is running.

Cong 2
Cong 3
Cong 4

Each conguration contains this submenu:

Subwoofers Off

PROFILE NAME

Using the navigation keys and volume knob each prole can be renamed, up to 10 characters long. Note that the prole
name is best set in Anthem Room Correction (Targets panel) because during le upload the name in the menu is overwritten

by the one in ARC.

SUBWOOFERS

The STR Integrated Amplier allows one or more subwoofers to be connected.

Although subwoofers are often thought of as something for home theater systems, their use is recommended for music
as well. A subwoofer normally plays bass that is louder, deeper, and less distorted than that of a full-range speaker, and it
can be positioned anywhere in the room to help cure resonances that otherwise make the bass sound bloated and lacking

denition. Anthem Room Correction quickly and easily creates precise calibration and seamless integration with the main

speakers, eliminating unnatural sounding transitions which often made subwoofers and main speakers sound disconnected
from one another regardless of the amount of time spent on tweaking.

The setting options are:

- O – select this if there is no subwoofer in the system or speaker prole.

- 1 Mono – a mono music signal gets sent to all subwoofer jacks. ARC will measure and correct all the subwoofers as a

group. This is the generally recommended setting whether using one or more subs.

- 2 Mono – a mono music signal gets sent to all subwoofers but ARC will measure and correct them separately for the
L and R output jacks. Select this if you intend to control the delay (distance) and level separately for each subwoofer

channel.

- 2 Stereo – the bass from the music source’s left channel will be sent to the L subwoofer output and the bass from the
right channel will go to the R output. ARC will measure and correct the L and R subs individually. Select this if you have

a subwoofer next to each main speaker and would like for them to use a stereo bass signal, especially if the crossover
frequency will be set closer to upper bass where the sound becomes directional.

7

3.2 BASS MANAGEMENT

In this menu, information about your speakers is used to optimize bass performance.

First, set your subwoofer’s frequency control to its highest frequency since the bass manager will determine how much upper

bass is sent. If your subwoofer has a contour control, set it to at if you will be using Anthem Room Correction. If it has a
phase control, set it to 0 and if it has a polarity switch, set it to Normal as you’ll be able to control phase and polarity from

your listening chair and hear changes instantly.

The bass manager divides the audio range into two bands suitable for subwoofer/satellite speaker systems. The result is

that the main speakers don’t need to play bass as loudly or as deeply since it gets picked up by the subwoofer. Note that a
crossover does not suddenly cut frequencies in a cli-like prole, but rolls them o according to a slope. If set to 80 Hz, for

example, frequencies lower than 80 Hz are still played by the main speaker while transitioning them to the subwoofer.

Highlighting Bass Management then pressing Select displays this menu:

Bass Management

Cong 1
Cong 2
Cong 3
Cong 4

Four congurations may be set up. Each contains the following:

Bass Management Edit

Crossover Off
Sub L Polarity Normal
Sub R Polarity Normal
Sub L Phase 0
Sub R Phase 0

CROSSOVER FREQUENCY

The range is 25 to 160 Hz in 5 Hz steps, or O which disables the crossover.

Setting the crossover to the lowest number on your speaker’s specication page is unlikely to provide the best result.

Instead, setting it to twice this frequency or thereabout, which is an octave higher, ensures that the speaker’s woofer will still
play to its low frequency limit but at levels that present less of a struggle for it.

If you will be using the personal computer version of ARC, you do not need to select the crossover frequency since it will be
set while running the program.

SUBWOOFER POLARITY AND PHASE

Certain subwoofer positions can cause bass frequency cancellation. When the front speakers and subwoofer are out of
phase or misaligned, they work against each other resulting in weak and dislocated sounding bass. This can be corrected by
adjusting Phase and Polarity.

As a general guide, set Polarity to Normal if the subwoofer is near the front speakers and to Inverted if the subwoofer is near
the back of the room. Compare Normal to Inverted and use the setting that provides louder bass. Continue ne-tuning the

crossover region using the Phase control which provides adjustment from 0 to 180 degrees in 5 degree increments.

3.3 LISTENER POSITION

Through these settings, sound coming from all speakers is coordinated to reach the listening area at the same time. This
way, proper imaging is achieved. The channel with the greatest distance setting will have no delay while channels with
shorter distance settings will be delayed accordingly.

Distances may be set before or after running ARC (ARC does not set distances).

Listener Position

Cong 1
Cong 2
Cong 3

3.4 LEVEL CALIBRATION

Level Calibration uses internally generated test noises to match speaker output levels at the listening position, if using an
SPL meter for calibration.

If using Anthem Room Correction, you can skip this menu because levels will be calibrated during measurement.

Level Calibration

Cong 1
Cong 2
Cong 3
Cong 4

These settings are displayed for each conguration:

Level Calibration Edit

Test Noise Off
Noise Level 0.0dB
Sub Left 0.0dB
Sub Right 0.0dB
Front Left 0.0dB
Front Right 0.0dB

To play the test noise, set it to “On” then highlight a speaker.

A sound pressure level (SPL) meter with C-weighting is recommended if not using ARC, especially to set the subwoofer

level because it is often set too high when calibrating by ear. Measure the sound pressure from the listening position while

pointing the meter up. Hold it away from your body to prevent reections. Adjust each channel’s level so the meter has the

same reading with all speakers.

The level adjustment range is -12.0 to 12.0 dB in 0.5 dB increments. You may need to adjust your subwoofer’s input level

dial as a rough adjustment.

Each input can be renamed, up to 10 characters long. To begin editing, press Next. The volume knob is the fastest means
of changing characters. Use the Next button to move to the next character, and when nished renaming, select the green
checkmark. To cancel editing, press Prev to select the red X.

Example – Rename “Optical 1” to “Server”:

• Highlight “Name” and press Next. The rst character will have a box around it.

• Use the up/down buttons or volume knob to change “O” to “S”.

• Use the Prev/Next buttons to move to each remaining character and complete the renaming.

• Move the box to the green checkmark to save the changes.

INPUT JACK

Select the connection to be used – Coaxial 1, Coaxial 2, Optical 1, Optical 2, AES/EBU, USB, RCA 1, RCA 2, RCA 3, RCA 4, Phono MM,
Phono MC, XLR.

CONVERT ANALOG

By default, analog inputs are converted to 24-bit / 192 kHz using a high-quality A/D converter to allow Anthem Room Correction,
bass management, distance calibration, bass/treble controls, listening modes, and rumble lter. If this setting is changed to No,

signal processing is bypassed and only level adjustment remains.

SPEAKER PROFILE

Select the prole to use with this input.

ANTHEM ROOM CORRECTION

The ARC measurement process, described later, will turn this on. To disable room equalization afterward, change this to “No”.
If a measurement le isn’t loaded, this menu item is grayed.

LISTENING MODE PRESET

By default, the output is in stereo but one of the other settings may improve the sound of old records. The mode can be changed
on the y but in this menu you can assign a preset according to input conguration.

- Stereo – this is the default and does not alter the channel mix.

- Mono – this blends the left and right channels and can be useful when playing mono records with a stereo cartridge.

Without this, stereo noise anking mono music can be distracting.

- Both = Left – this sends the left input to both channels and can be useful when playing a mono record with a stereo
cartridge when the left groove wall has less wear and sounds better than the right groove wall. This is also useful with
sources that have only one output connector.

- Both = Right – like above but for the right channel.

- Last Used – select this to disable presets and make selections entirely on the y.

RUMBLE FILTER

Use this to roll o low-frequency noise below the spectrum of the music when using a turntable. Select a frequency from
10 to 60 Hz in 1 Hz increments. To disable the rumble lter, select O.

3.6 ANALOG INPUT LEVELS

Through this menu, unwanted changes in volume when switching to or from an analog source can be prevented. This is

especially useful for some XLR sources that produce higher than typical output level, and for the phono inputs since cartridge

output levels vary considrerably between models.

Analog Input Levels

RCA 1 0.0dB
RCA 2 0.0dB
RCA 3 0.0dB
RCA 4 0.0dB

Phono MM 0.0dB

ANTHEM ROOM CORRECTION (ARC)

For anyone reading this, the experience of walking into a room and being struck by the dramatic change in its sound
after carpet and furnishings have been moved out is probably a familiar one. It may also bring to mind the varying sound
character from one room to the next according to its size and structural qualities.

By the same token, even when the nest speakers are optimally positioned, the room impacts sound quality
considerably. The walls, oor, ceiling, and windows add unwanted resonance and coloration making bass less
impactful, voices less natural, and dialogue less intelligible. The eect on frequency response is typically ±6 dB in
the midrange and ±10 dB at low frequencies. To compensate for this and to optimize the in-room response of your

speakers, Anthem Room Correction measures the output of each one relative to the listening area then through a
special series of calculations adjusts the output accordingly. Its target responses have a psychoacoustic basis from
research results, not just theoretically ideal curves.

While removing resonances and modal peaks common to the measurement positions, ARC also distinguishes and

preserves the positive eects imparted by the room by detecting how much the room’s boundaries and pressurization
reinforce low frequencies. This eect, known as room gain, appears as a bump in the target response. ARC does not
remove it because if attened, bass sounds thin. Our ear/brain mechanism expects to hear this characteristic when

indoors. Ideal anechoic speaker response, as measured in a special non-reverberant facility, is not the same as ideal
in-room response, which normally includes this room gain to varying degree. It is one reason that a speaker sounds

dierent outdoors when in fact it is the same speaker. If a speaker indoors was forced to sound like it’s positioned

outdoors, it just wouldn’t sound right.

Sample curves:

The red curves represent the in-room response before correction, as an average from ve measurement positions,

whereas the green ones show response with equalization applied. In this case a subwoofer and bass management are

also in use. In the subwoofer graph, which is on the left, the dierence between the level of the red and purple curves

shows the amount of room gain.

In addition, ARC senses where each speaker’s low-frequency response naturally declines, and sets the high-pass lters to

match this natural limit.

The default correction range is 5 kHz. Although it can be changed to a lower frequency if desired, raising it is not

recommended. At higher frequencies the microphone becomes directional thus aecting measurement accuracy.

Note that the subwoofer graph may imply that the subwoofer plays up to the highest frequency shown, but what it plays

depends on what the other channels send to it as determined by their crossover setting. The subwoofer graph shows the
available correction range, which is not necessarily the range that other channels send to it through bass management.

19

4.1 BEFORE STARTING

Ensure that the processor software and ARC-2 software that you will be using are compatible with one another.
Check www.anthemAV.com for latest versions.

PERSONAL COMPUTER VERSION OF ARC:

• Your computer must be running Windows 7 or later and be connected to the same network as the processor, or
directly to the processor with the supplied USB Mini cable.

• Depending on your network’s settings, you may need to enable sharing to allow the processor to be seen by
your computer.

• If you are using a laptop computer, check its power settings and battery meter to ensure that procedures will not
be interrupted.

MOBILE APP VERSION OF ARC:

• Congure the Speaker Setup menu before measurement if your speaker system does not correspond to the existing
menu conguration.

BOTH VERSIONS:

• If more than one processor is on your network, each may be identied by MAC address, IP address, or the Device
Name which appears in the setup menu.

• Ensure that the room will be suciently quiet during measurement. Typical background noise is detected and

rejected with no impact on measurement accuracy but if excessive noise is present, ARC will indicate that re­measurement is required.

• If using a subwoofer, ensure that its crossover frequency dial is set to its highest frequency before measurement.
ARC will manage the transition between the main speakers and subwoofer. Any adjustments to the subwoofer after
measurement would require ARC to be run again.

4.2 ARC SOFTWARE INSTALLATION

MOBILE APP VERSION:
On the iTunes store, locate Anthem ARC Mobile and install it to your device.

PERSONAL COMPUTER VERSION:

1. Go to https://www.anthemav.com/support/latest-software.php

2. Download the software. Depending on ARC microphone model, a support le named using the microphone’s serial
number may be required. If your microphone is numbered, enter its number on the web page before downloading. Be

sure to enter the correct number otherwise the frequency response will be inaccurate.

3. Unzip the download.

4. Run setup.

To add a new numbered microphone after ARC has been installed, re-installation isn’t needed - simply copy new

calibration les to this directory:

(Computer, OS) C:\Program Files (x86)\Anthem Room Correction 2

During measurement, ARC will list the installed les and ask you to pick the one corresponding to the microphone in use.

What are the dierences between the computer and mobile versions of ARC?

1. With the phone’s internal microphone there may be minor variations from ideal response. The
maximum equalization frequency is restricted to 2 kHz in this case. The external dual-jack microphone
using 3.5mm connection is preferred since it provides the same measurement accuracy as the main

kit’s USB microphone.

20

2. The computer version allows viewing and printing curves, target curve customization, and multiple
congurations for dierent applications that may be useful according to various sources, conditions,
and preferences.

4.3 MICROPHONE STAND ASSEMBLY

If using the mobile device’s microphone, skip this section.

1. Loosen the tripod base screw, move the base to the bottom of the telescoping tube, re-tighten the screw.

2. Screw the microphone clip to the other end of the stand. Position the clip vertically.

3. Connect the USB microphone cable to the microphone and slide the microphone into the clip.

4. Adjust height by rst loosening the clamps on the telescoping tube and on the arm. The stand may be placed on the oor

or on the seat according to whichever way puts the microphone capsule in its proper position.

4.4 MICROPHONE POSITIONING

This section mainly applies to the personal computer version and full ARC kit since the mobile app version will guide you
when using the mobile device’s microphone or the dual-jack microphone. The dual-jack microphone may also be used with

the microphone stand and/or the PC version of ARC via USB connection.

Proper microphone positioning is essential for good results. Multiple positions are required to prevent standing waves or
boundaries from skewing results.

• The microphone must point straight up.

• The microphone capsule, the listener’s ears, and the speaker’s acoustic center (or tweeter if in doubt) should be
at approximately the same height. If the result sounds dull or bright try a dierent microphone height and repeat

measurement.

• The rst microphone position must be at or just in front of the central seating position. Speaker levels are calibrated from

this position. For the remaining positions, place the microphone in the most often used parts of the listening area while

ensuring that all mic positions are at least 2 feet (60 cm) apart. If there is only one listening position, positions 2 through 5

must be a circle or box around the listening chair - do not use a position more than once!

• Five dierent positions, and no less, are normally adequate but for larger rooms up to ten may be used.

If most or all listening positions are close to a wall:

• At least half of the microphone positions should be a minimum 2 feet (60 cm) away from the wall.

• Vary distances between microphone and wall by 1 foot (30 cm) or more, for example two or three positions can be 2 feet
(30 cm) away but the remaining two or three should be at least 3 feet (90 cm) away.

In summary:

DO

- Set the mic at ear level pointing straight up.

- Use mic positions that are at least 2 feet (60 cm) apart from each other even if there’s only one seating position.

- Use more than ve measurement positions if using only ve would result in their being more than 6 feet (2m) apart due

to a large listening area.

- Start with the rst measurement position in the center of the listening area.

DO NOT

- Use mic positions close to walls. If all seating positions are against the rear wall, three or more mic positions should be in

front of the seating area. Vary the distance of these positions relative to the wall by 1 foot (30 cm) or more so they are not

all the same distance from the wall.

21

4.5 MEASUREMENT

The remaining ARC instructions apply to the personal computer version. If using the mobile version, follow its instructions instead.

• Connect the microphone and the processor to the computer.

• Set the microphone in the rst position. Don’t stand near the microphone while sweep tones are playing otherwise
reections from your body may cause bad measurements.

• Run Anthem Room Correction. Use Automatic mode if you are a rst-time user. It will guide you through the remaining
steps and at the end will load the correction data to your processor. You will still be able to change things if needed, but
just remember where you’re saving the .arc2 measurement le so you can nd it later. The entire process takes about 5-10
minutes depending on the number of measurements and congurations.

• Up to 16 characters may be used to name a measurement. Valid ones are: a-z, A-Z, 0-9, “ “, “-”, “.”, “:”, “;”, “<”, “=”, “>”, “?”, and
“@”. The rest will be removed if used.

• Once the ARC program has completed its procedure, you can disconnect the computer.

• Save your settings in the processor’s setup menu using its Save / Load Settings menu.

QUICK MEASURE SPEAKER POSITION HELPER

If speaker positioning is exible, particularly for the sub, Quick Measure can help you with speaker positioning especially if an

initial ARC measurement shows that there is room for improvement.

To use it, run ARC Manual mode. Click on the Quick Measure button and enable the sweep tone for the speaker that you are
positioning. Note that this will reset level calibration. After a few sweeps the graph will show a live update of the uncorrected
measurement. It will keep running until you turn it o. After nding good speaker positions, run the full ARC measurement.

The graphs that follow show how moving a subwoofer can improve uncorrected response. Large dips like these are not

uncommon:

22

They can almost always be cured by repositioning speakers and repeating the measurement:

4.6 MANUAL MODE AND TARGETS

When creating a new measurement, Manual and Automatic modes operate identically except that automatic mode does not
require clicking on Measure, Calculate, and Upload between these stages. It also allows results to be viewed before upload,

and for Targets to be edited. A le created in Automatic mode can later be opened in Manual mode.

A le created in Automatic mode can be opened in Manual mode to allow target editing. After changing targets, you must

click OK when closing the window to apply the settings, then Calculate. To restore original settings, click on Auto Detect then
Calculate.

23

For advice in getting the most out of your system based on your measurements, we welcome you to send your .arc2 le
(please do not send screenshots) to Anthem Technical Support.

WHAT NOT TO DO

Before we get to that, something to be aware of if at rst listen it appears that the equalization has reduced overall bass: It is

easier to hear peaks in response than dips. ARC doesn’t only level the peaks, but also the dips. With the equalization turned
on it may be immediately apparent that boominess is gone, but it may take longer to notice that bass notes which were
buried all along have become audible, and for this reason you might want to spend a week getting used to the new sound.
Once becoming accustomed to tight bass with the entire range playing at equal level, chances are you’ll never want to go
back to bloated one-note bass.

If comparing ARC on vs o, note that the subwoofer’s level is calibrated according to ARC being on. If ARC is then disabled,

subwoofer level may need adjustment.

Viewing graphs for the rst time may cause temptation to immediately change targets. There is rarely a good technical
reason to do so. If you are not satised with initial results, examine the red pre-correction measurement curve. It shows how
your system performed all along without room correction. Does this reect the general performance expected from your
speakers, especially in the bass? If not, do not try to compensate through electronic correction. It bears repeating that it is

not meant at all to be a substitute for proper speaker positioning, nor can it reliably force your speakers to do something
they weren’t designed to do. Its purpose is to take performance to a higher level after the traditional good practices that

existed before room correction have been fullled.

The following is a classic case of what not to do - an attempt to turn a “full-range” speaker’s woofer into a subwoofer by
manually lowering the equalization cuto from 35 Hz to 25 Hz and the slope from fourth order to a more gradual third order.
Such changes are very unlikely to end well. The extra stress on the speaker from approximately 20 Hz to 30 Hz could easily
lead to woofer and/or crossover damage from overextension or overheating (+6 dB equates to four times the power). The
amplier will also generate more heat, something that is not good for any electronic device.

Always avoid forcing the green curve to be higher than the red or purple ones in the manner shown here:

24

In contrast, this is the same measurement with the original targets that were automatically detected and set by ARC. Notice
how the left side of the target curve complies to the speaker’s natural rollo:

MAX EQ FREQUENCY

The default correction range is 5 kHz. This may be lowered for experimentation or comparison.

ROOM GAIN

If you wish to experiment by attening room gain, you can try it by setting this to 0 dB. Note that auto-detected room gain will
be at or near 0 dB if bass absorbers are used or if the speakers are light on bass extension.

Alternatively if you would like to increase or decrease bass, this is the best place to do so if using a subwoofer since a good
sub-mains transition will be maintained.

25

4.7 ADVANCED SUBWOOFER TARGETS

Use of these controls is recommended only for the advanced user who understands the subwoofer’s capabilities and
behavior when fed low frequencies at high levels. As always, check whether changes are worthwhile by listening to a variety
of source material before and after modifying targets.

SUBWOOFER HIGH PASS ORDER

Change the low-end slope only if for some reason the auto-detected one doesn’t match the low-end rollo of the

measured response. The left side of the red or purple measured curve is the guideline for shaping the target curve. As
mentioned earlier, an attempt to use this as a means of extending low-frequency output beyond the speaker’s capability
will be detrimental.

SUBWOOFER HIGH PASS FREQUENCY

Use this in conjunction with High Pass Order when manually creating a curve for the lower end of the subwoofer’s response.

MINIMUM SUBWOOFER EQ FREQUENCY

Change this only if you would not like for ARC to equalize the subwoofer channel below a certain frequency.

LIMITED WARRANTY

CANADA & USA

The warranty period on new Anthem products is:

5 years: Separate power ampliers and integrated ampliers
3 years: Audio/Video preampliers and receivers

Please register your product at www.anthemAV.com

The warranty period begins on the date of purchase from Anthem or an Authorized Anthem Dealer. This warranty is oered

only to the original owner and is not transferable. Demonstration and display units are covered by the same warranty except

that the period commences on the date of dealer invoice, not the purchaser’s invoice, and cosmetic aws are excluded.

If Anthem determines that the product has a defect in materials or manufacturing during the warranty period Anthem will at
its option repair, replace or provide the necessary replacement parts without charging for parts or labor. Repaired or replaced
equipment or parts supplied under this warranty are covered by the unexpired portion of the warranty.

Warranty is void if the serial number has been removed, altered or defaced, if the product has been operated, installed or

handled other than in accordance with the intended application, tampered with, modied, or damaged by accident, while in

transport or by failure of electric power, or has been repaired by a non-authorized party. Anthem shall have no obligation
to correct any defect that is not reproducible by Anthem. If inspection by Anthem discloses that the repair required is not
covered by this warranty, regular repair charges shall apply.

If a problem is discovered in your Anthem product, please contact the Authorized Anthem Dealer from whom you purchased

the product. Your dealer will help to determine the cause of the problem and arrange for the appropriate action. Alternatively,

follow the procedure below for factory service.

A Return Authorization (RA) number must be obtained from Anthem Technical Support before a product can be shipped to
Anthem for any reason. Product shipped to Anthem without its RA Number clearly visible on the outside of the shipping carton

will be refused and returned to the sender, freight collect. Product shipped to Anthem must have shipping and insurance
prepaid by the sender, be packaged in the original carton and packing material and accompanied by a written description of

the defect. Service will not be given under warranty without an accompanying copy of the sales invoice. Product repaired
under warranty will be returned with shipping and insurance prepaid by Anthem (within Canada and continental USA only).

DISCLAIMER OF LIABILITY

Under no circumstances shall Anthem, its agents, representatives or employees assume liability or responsibility for injury or

damages sustained in the use or operation of Anthem products or for damages to connected products. Some jurisdictions do

not allow limitations of incidental or consequential damages so this exclusion may not apply to you.

Anthem reserves the right to make design changes without obligation to revise prior versions. All specications are subject to

change without notice.

This warranty shall be the sole and exclusive remedy to you. No other warranty or condition, statutory or otherwise, expressed

or implied, shall be imposed upon Anthem nor shall any representation made by any person, including a representative or

agent of Anthem, be eective to extend the warranty coverage provided herein.

On the expiration of the warranty all liability of Anthem in connection with the product shall terminate.

INTERNATIONAL

Terms and conditions are set and maintained by the Authorized Anthem Distributor, not Anthem.
