ACCESSING THE CONFIGURATION INTERFACE

For initial setup, the MDA should be connected to a network and plugged into the wall with the On Mode switch set to EXT CMD. Turn on the MDA by setting the master power switch to On. The Power light on the front panel indicates that the MDA has powered up. Once the LAN light on the front panel turns blue or red, the MDA has connected to your network and acquired a network address.

The MDA is congured using an interface accessed using a web browser. Identify the MDA’s IP address to proceed. You can discover the MDA’s IP address using the ARC Genesis software (available on AnthemARC.com). Start the program, choose Launch ARC, and hover your mouse cursor over the MDA, wait for a second, and it shows the IP address in the device discovery screen. Note that the last few characters of the unit’s name correspond to the end of the MAC address printed at the back of the MDA.

To access the MDA’s conguration interface, open a web browser (we recommend Chrome or Safari), type the IP address into the browser’s address bar, and hit enter.

When installing more than one MDA, there are multiple IP addresses. To identify each MDA, use a web browser to connect to the rst one and click General > Preferences > Unit ID. The ID light on the back panel ashes as will the Power indicator on the front of the MDA. The MAC Address displayed under General > Information matches the unique MAC Address printed on the back of the MDA.

or keep them as Generic type if not shown in the list.

6. Zones > Zone 1 > Subwoofer > Subwoofer: When there is a sub connected to the zone’s Sub Out, set the toggle to on.

7. Repeat for additional zones.

1. Access the conguration interface by entering the MDA’s IP address in a web browser’s address bar.

2. General > Information > Device Name: Create a name for the MDA and click Apply.

3. Inputs > Analog 1 (or other input) > Input Name: Create

a name and click Apply

4. Repeat for additional inputs.

RUNNING ANTHEM ROOM CORRECTION (ARC®)

Once speakers and subwoofers are connected and congured, and sources and zones are named, you can run room correction for each zone that is being used. Download the ARC Genesis software from AnthemARC.com and follow the onscreen instructions. See section 4 for additional details.

CONTROLLING THE MDA

Play music using one of the sources connected to the MDA. In most installations, a custom integrated control system is used to adjust the volume and change which source is playing in which zone. You can also adjust volume and change inputs using the conguration interface.

• Access the conguration interface by entering the MDA’s IP address in a web browser’s address bar.

• Zones > Zone 1 (or another zone) > Zone Settings > Input Source: Choose the input you want to hear in this zone.

• Zones > Zone 1 (or another zone) > Volume > Zone Volume: Adjust the volume here.

1.8 SETTING UP A CONTROL SYSTEM

5. Zones > Zone 1 > Zone Settings > a. Zone Name: Create a name and click Apply.

b. Input Source: Choose the input you want to hear in

this zone.

MDAs are compatible with IP and RS232 command protocols. A detailed command set and discovery protocol are available on MartinLogan.com. A variety of MartinLogan developed automation drivers are also available for download free-of-charge from our web site for easy integration into a smart-home powered by Crestron, Savant, and other similar controllers.

2. THE USER INTERFACE

For optimum performance and enjoyment, your MDA should be appropriately set up. If you’re using a subwoofer or subwoofers, ARC (Anthem Room Correction) sets crossovers and levels for a perfect blend with the main speakers. The rest of the settings mostly relate to your preferences. Please fully congure all zones with the proper output modes (single-ended, stereo or mono bridge), speaker prole and subwoofer settings (present or not, active or passive) before running ARC.

2.1 ACCESSING THE USER INTERFACE

For initial setup, the MDA should be connected to a network and plugged into the wall with the On Mode switch set to Auto.

Turn on the MDA by setting the master power switch to On. The Power light on the front panel indicates that the MDA has powered up. Once the LAN light on the front panel turns blue or red, the MDA has connected to your network and acquired a network address.

2.2 FINDING THE MDA’S IP ADDRESS

The MDA is congured using an interface accessed using a web browser. Identify the MDA’s IP address to proceed.

You can discover the MDA’s IP address using the ARC Gene-

sis software. Start the ARC program on a PC or Mac, choose Launch ARC, and hover your mouse cursor over the MDA, wait for a second, and it shows the IP address in the device discovery screen.

We also recommend using Fing, a free network device detection app available on iOS, Android, and Windows. This app identies devices on a network and shows their IP addresses. These identify with MDA8 or MDA16 or MartinLogan.

To access the MDA’s conguration interface, open a web browser (we recommend Chrome or Safari), type the IP address into the browser’s address bar, and hit enter.

2.3 IDENTIFYING MULTIPLE MDAs

When installing more than one MDA, there are multiple IP addresses. To identify each MDA, use a web browser to connect to the rst one and set General > Preferences > Unit ID to On. The ID light on the MDA’s back panel and the Power indicator on the front ash. The MAC Address displayed under General > Information also matches the unique MAC Address printed on the back of the MDA. Note that the last few characters of the factory default unit’s name correspond to the end of the MAC address printed at the back of the MDA.

2.4 ZONES

Zones: Adjusts the settings of individual zones, allowing

zone naming, source selection, mode setup, listening mode, speaker prole, level adjustment, tone control, volume conguration, and subwoofer setup. The top of the page shows the individual zones.

Inputs: Allows input naming and level balancing (trim). See

section 2.5 for additional details.

General: Displays device information and allows device

naming, network conguration, and displays input selection. See sections 2.6 – 2.9 for additional details.

Store/Load: Allows import/export of device settings from

les saved on your PC or Mac. Also allows storing and loading from 2 local storage areas (user’s or installer’s settings).

The user interface design is subject to change.

See section 2.10 for additional details.

The Zone taskbar shows available zones and highlights the

currently selected zone (MDA16 shows 8 zones, and MDA8 shows 4 zones). Stereo Bridge and Subwoofer Powered by Zone 2 (4, 6, or 8) turn the even-numbered zones grey, indicating they are disabled. In this case, settings and controls of the odd-numbered zone transfer automatically to the even-numbered zone.

Mono Bridge: Sets a single zone into a high output mode

for a single speaker. The listening mode is automatically set to Mono when selecting Mono Bridge mode. See section 3.4 for additional details.

Stereo Bridge: Sets a zone pair (1 & 2, 3 & 4, 5 & 6, or 7 & 8) into

a left and right conguration. When activated, the even-numbered zone turns grey, and the odd-numbered zone controls the settings. This setting allows a high output mode for a pair of speakers with each zone acting as a discrete channel. The listening mode is automatically set to stereo when selecting Stereo Bridge mode. See section 3.5 for additional details.

Zone Power: Toggles the zone between active and stand-

by. When set to Auto mode and music is playing in that zone, the toggle automatically goes back ON when analog or digital audio is detected.

ARC: Turns ARC on and o for the zone (only available if ARC software has been used to upload corrections for the zone).

Bass / Treble: Allows ne-tuning of the relative bass and

treble levels of the system. Please note that if using a subwoofer, the subwoofer level adjusts the subwoofer level relative to the main channels.

Left / Right: Adjusts the level of the left and right channels

to set the balance.

Subwoofer: Activates and deactivates the subwoofer and

bass management. Subwoofer output does not function unless this toggle is enabled. By default, the subwoofer signal is output using the Sub Out RCA connection for the zone. If using a subwoofer, enable this before running ARC. See section 3.6 for additional details.

Zone Name: Assign a name to the zone (up to 16 charac-

ters) and click Apply to save this setting. The names of the zones appear in ARC, allowing easy identication.

Input Source: Selects the desired input source. An input

can be assigned simultaneously to multiple zones. If you are not using the built-in matrix switching this remains static until altered either through the web interface or IP/ RS232 control. Selecting a source here does not prevent you from changing source dynamically during use through a compatible home automation system.

Listening Mode > Stereo: The default listening mode. The

audio plays in stereo.

Listening Mode > Mono: Sums the left and right channels and sends identical signals to both speakers.

Speaker Prole: Selects a specic in-wall or in-ceiling

speaker model for each zone. Selecting a particular model allows the DSP to optimize the EQ and limiter settings. Enable a Speaker Prole using the toggle button located right of the drop-downs. If you don’t know the model of your speakers, or if your speakers are not listed, select Generic.

Zone Volume: Adjusts the level of the zone. Each zone has

independent volume control. Please note that selecting a volume level in the Web UI does not prevent you from changing volume levels dynamically during use with a compatible automation system.

Power On Volume: The volume level for the zone when it

turns on.

Max Volume: Prevents the volume of the zone from ex-

ceeding the desired level. Please note that an external volume adjustment cannot override this level. If an automation system attempts to adjust the volume level higher than the max volume setting the MDA ignores the command.

Mute: Mutes the zone.

Crossover: Sets the crossover point between the sub-

woofer and the main speakers. When using ARC, this value is automatically set. To change the crossover value after running ARC, modify the crossover setting in ARC and then re-upload. The crossover should only be manually adjusted if you are not using ARC.

Sub Level: Adjusts the level of the subwoofer relative to the mains. When using ARC, this value is automatically set. Unlike the Crossover setting, manually changing this value after run ning ARC will not negatively impact subwoofer integration.

Sub Phase: Adjusts the phase of the subwoofer relative

to the main channels. Phase is adjustable from 0-180 degrees. If a value higher than 180 degrees is required, adjust Subwoofer Phase in combination with Sub Polarity for a full 360-degree range of adjustment. When using ARC, this value is automatically set using the Automatic Phase Adjustment tool.

Sub Polarity: Adjusts the polarity of the subwoofer to ei-

ther 0 or 180 degrees. When selecting 180 degrees, the subwoofer signal is inverted when compared to the main channels. As a general guide, set Phase and Polarity to 0 if the subwoofer is near the front speakers and set Phase to 0 and Polarity to 180 if the subwoofer is near the back of the room. When using ARC, this value is automatically set using the Automatic Phase Adjustment tool.

tive zones to operate together for a stereo pair of speakers and a dedicated passive subwoofer connected in bridge mode (and must be connected as such on the rear panel of the unit). When engaged, all adjustments are made using the controls in the odd-numbered zone, and the even-numbered zones controls are disabled. For example, when engaged, Zone 1 controls both left and right speakers connected to Zone 1 and the subwoofer connected to Zone 2. Enable this feature before running ARC. See section 3.7 for additional details.

The user interface design is subject to change.

2.5 INPUTS SETTINGS

Bulk Action: Use this when you want to change input

names without clicking apply after each change. Enter names for all applicable inputs, select Check All from under the Bulk Items drop-down, then select Apply from under the Bulk Items drop-down.

Input Name: Assign a custom name for each input (up to

16 characters). You must click Apply to save this setting.

This name corresponds with the input list in the MDA’s user interface. Please note, this does not necessarily change the input name in associated control systems.

Trim: Adjusts the relative level of each input. Use this when

one input plays at a dierent level than the others, causing changes in volume levels during playback while switching between sources.

The user interface design is subject to change.

3. CONNECTIONS AND BACK PANEL CONTROLS

3.1 LOCAL AREA NETWORK CONNECTION

bridge mode uses a single zone whereas stereo bridge

uses two consecutive zones to drive a stereo pair. A network connection is required to access the conguration interface, run Anthem Room Correction, and use IP control.

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 o when connecting or disconnecting anything. As well, be sure to use speakers rated for use with this MDA – an overdriven speaker can pose a re hazard.

secutive zones (zones 1/2, 3/4, 5/6, or 7/ 8).

It is possible to mix-and-match zone congurations within a single MDA. For example:

• Zone 1 (Kitchen): left & right speakers

• Zone 2 (Bathroom): left & right speakers

• Zones 3/4 (Den): left & right speakers bridged for more

power in stereo mode

• Zone 5/6 (Living Room): left & right speakers with a pas-

3.3 CONNECTING STEREO SPEAKERS

ANALOG OUT

Connect a pair of speakers to a zone using a Euroblock (also known as a Phoenix cluded with the MDA and come preinstalled. Euroblock connectors accept speaker wire up to 12 gauge. Use speakers as low as 4 Ohms in this conguration.

1. Remove the zone’s Euroblock connector from the MDA by gently pulling it until it releases.

2. Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection on the left speaker to the positive (L+) contact on the Euroblock connector as indicated by the printing located on the MDA (above the connector) or on the connector itself.

4. Connect the black (–) connection on the left speaker to the negative (L–) contact on the Euroblock connector as indicated by the printing located on the MDA (above the connector) or on the connector itself.

5. Repeat for the right channel.

6. After attaching speaker wires to the Euroblock connector, insert it into the MDA by gently pressing it into place.

3.4 CONNECTING MONO SPEAKERS

ANALOG OUT

L+R

USING ONE BRIDGED ZONE

A zone set to mono mode can be used to drive a single speaker, allowing the MDA to deliver more power per channel. Enabling mono bridge sets the listening mode to mono automatically. Bridge mode only supports speakers rated for 8 Ohms or higher. Any zone set to Mono Bridge can use an active sub connected via the zone’s Sub Out. An odd-numbered zone set to Mono Bridge can use the matching even-numbered zone to power a passive subwoofer using the Powered by Zone 2 (4, 6, or 8) setting.

Speaker Connection:

1. Remove the Euroblock connector by gently pulling it until it releases.

2. Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection of the speaker to the positive (R+) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

4. Connect the black (–) connection of the speaker to the negative (L–) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

Enabling Bridge Mode:

1. Enable bridge mode via the web interface by going to

Zones and selecting Mono Bridge in the desired zone. The Listening Mode is set automatically set to Mono.

3.5 CONNECTING STEREO SPEAKERS

ANALOG OUT

USING TWO BRIDGED ZONES

Using two zones to drive a single stereo pair of speakers allows the MDA to deliver more power per channel. When bridging, two consecutive zones are used to drive the stereo pair (Zones 1 and 2, 3 and 4, 5 and 6, or 7 and 8). Bridge mode only supports speakers rated for 8 Ohms or higher. The only option to use a subwoofer in this conguration is the use of an active sub connected via Sub Out, and the MDA will no longer respond to IP or RS232 commands for the even-numbered zone.

Left Speaker Connection:

1. Remove the Euroblock connector from the odd-numbered zone by gently pulling it until it releases. The left speaker connects the odd zone.

2. Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.

Connect the red (+) connection of the left speaker to the positive (R+) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

Connect the black (–) connection of the left speaker to the negative (L–) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

5. After attaching speaker wires to the Euroblock connector, insert it into the MDA by gently pressing it into place.

Right Speaker Connection:

1. Repeat for the right speaker by making a similar connection on the next even zone (for example, if you just attached the left channel to zone 1, connect the right speaker to zone 2).

Connect the red (+) connection of the right speaker to the positive (R+) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

Connect the black (–) connection of the right speaker to the negative (L–) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

4. After attaching speaker wires to the Euroblock connector, insert it into the MDA by gently pressing it into place.

Enabling Bridge Mode:

1. Enable bridge mode via the web interface by going to Zones and selecting Stereo Bridge in the desired zone. Controls for the even-numbered zone become unavailable, and the odd-numbered zone now controls settings for both speakers.

3.6 SUBWOOFER OUTPUTS

ANALOG OUT

SUB

If you’re using this MDA to power a passive (non-powered) subwoofer refer to the next section. To connect a powered subwoofer, use an RCA cable, connect a zone’s Sub Out to a powered subwoofer LFE input, and enable the subwoofer using Zones > Subwoofer. If the powered subwoofer doesn’t have an LFE input, connect to either the left or right input and set the sub’s low-pass lter (commonly referred to as crossover) to its highest or bypass setting. Please refer to your subwoofer’s manual for specic connection and control setting instructions.

This control also enables the high pass lter on the left and right outputs. If you are not using ARC and do not have a subwoofer connected, you can enable this control and set the crossover frequency. This will avoid overloading speakers that don’t support a full-range signal.

3.7 CONNECTING A PASSIVE

ANALOG OUT

SUB

(NON-POWERED) SUBWOOFER USING A BRIDGED ZONE

If using a passive (non-powered) subwoofer, an even-numbered zone can be congured to power the sub. This mode only supports subwoofers rated at 8 Ohms or higher. The even-numbered zone is bridged to provide more power. For example, in Zone 1 connect the left/right speakers using the stereo pair conguration and in Zone 2 connect the passive subwoofer by following these instructions:

1. Remove the zone’s Euroblock connector from an even zone of the MDA by gently pulling it until it releases.

2. Use a small slotted screwdriver to loosen and tighten each contact on the Euroblock when inserting the speaker wire.

3. Connect the red (+) connection of the subwoofer to the positive (R+) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

4. Connect the black (–) connection of the subwoofer to the negative (L-) contact on the Euroblock connector as indicated by the printing located on the MDA (below the connector).

5. After attaching subwoofer wires to the Euroblock connector, insert it into the MDA by gently pressing it into place.

Using the web interface enable the subwoofer bridge mode in the Zones > Subwoofer menu and then enable Powered by Zone 2 (4, 6, or 8). Note that the even zone parameters become un available when this mode is enabled. The odd zone screen determines the input source, level, crossover, phase, and polarity.

3.8 DIGITAL INPUTS

Stereo digital audio sources can be connected using coaxial or optical cables. The MDA16 has two digital optical inputs, and two digital coaxial inputs and The MDA8 has one digital optical input. All of these inputs support the PCM stereo format (up to 24-bit / 192kHz). If using sources that have an option for selecting between PCM and Bitstream (or Dolby Digital) audio output, select PCM. If the source outputs a non-PCM stream (such as a Dolby or DTS stream), the audio will mute.

3.9 DIGITAL OUTPUT (MDA16 ONLY)

The digital optical output on the MDA16 provides a repeat function to feed an additional MDA (or any other component that accepts digital optical input). This output supports up to 24-bit/192kHz and can be congured to output any of the MDA’s digital inputs (including digital coaxial). Select any of the digital inputs via the web interface by clicking on Digital Out Source in the General > Preferences screen and selecting the appropriate digital input.

3.10 ANALOG INPUTS

Connect stereo analog sources using RCA cables. The MDA16 has eight stereo RCA line inputs. The MDA8 has four stereo RCA line inputs.

3.11 ANALOG OUTPUTS (MDA16 ONLY)

The MDA16 has two stereo analog RCA line outputs. Any audio source connected to the Analog 6 input passes unaltered to the Analog 6 Out. Any audio source connected to the Analog 7 input passes unaltered to the Analog 7 Out. These act as “pass-throughs” and work even when the MDA is in standby or powered o.

3.12 POWER

The trigger also works with the On Mode switch set to Auto. See section 3.15 for additional details.

3.14 RS-232 CONNECTION

The RS-232 connection allows connection to a compatible control system. The control system should be congured to use 115200/8-N-1, no ow control, protocol. The cable connection should be one to one.

3.15 ON MODE SWITCH

With the three-way switch located on the back panel, you set the way the MDA turns on and o.

• Trig: This sets the MDA to turn on and o when it receives a signal on its Trig In connection. See section 3.13 for additional details.

• Auto: This sets the MDA to turn on when it detects an incoming signal on any of its digital or analog audio inputs. When the MDA stops detecting all incoming audio signals, it enters standby mode after approximately 20 minutes (by default). O and on times can be adjusted via the web interface. Go to General > Preferences > Auto-O Delay and Auto-On delay. The trigger input also works in this mode. The MDA will turn on when a signal is applied to Trig In, even if no audio signal is detected. The unit will enter standby mode after the Auto-O delay once the trig signal is removed and no audio signal is detected.

• Ext Cmd: This sets the MDA to ONLY turn on and o when it receives commands from an IP or RS-232 control system.

Note that commands can be sent in any mode of operation. For example, the volume may be changed whether the switch is set to Auto or Trig. You will not be able to turn on a zone using a command if in Trig mode and the trigger input is de-asserted, but a turn on command will work if the On Mode switch is set in Auto mode.

Insert a power cord into the MDA’s AC input. Plug the cord into a wall outlet. Ensure that the AC supply matches the voltage rating shown on the back of the MDA. The 230V models support voltages from 220V to 240V.

3.13 TRIGGER CONNECTIONS

The trigger connection allows the MDA to be turned on or o via the trigger input. When either Trig In 3.5mm (1/8”) minijack receives power (5–24 volts DC or AC) from an upstream component, the MDA turns on (Auto-On delay applies). When it stops receiving power, the MDA turns o immediately. The second Trig In jack allows you to run a cable out to daisy-chain and trigger additional MDAs. For this function to work the On Mode switch must be set to Trig. Please note, do not connect triggers from two upstream components at the same time. Always use one as an input and one as an output.

3.16 MASTER POWER SWITCH

This switch is wired directly to the AC mains and turns on and o all power going to the MDA.

3.17 DHCP OR FACTORY IMAGE RESET

This reset button allows you to manually reset the MDA’s network connection DHCP settings or restore the MDA to the original factory image. See section 7 for additional details.

3.18 ID INDICATOR

When multiple MDAs are in a rack, you can quickly identify each MDA by making use of the ID indicator. Use a web browser to connect to the control interface of the rst MDA and enable Unit ID under General > Preferences. The ID light on the

back panel ashes as will the Power indicator on the front of the MDA. You can also match the MAC Address shown under General > Information with the unique MAC Address printed on the back of each MDA.

3.19 ARC MICRO-USB CONNECTION

If a local area network connection is not available the Anthem Room Correction (ARC) software can still connect to the unit by making use of this micro-USB connector. Connect a USB type A to micro B cable between the MDA and your PC or Mac.

3.20 CHASSIS GROUND

The MDA is powered using a double-insulated power cord and therefore does not have an earth ground connection to avoid hum. If an earth ground connection is required, or if connecting to another chassis ground, you can connect a wire using the thumbscrew.

3.21 FUSE

To replace the fuse, rst set the Master Power switch to O and disconnect the power cord, Using a small slotted screwdriver, remove the fuse cap and replace the fuse with a matching type and rating as shown at the back of the unit.

4. ANTHEM ROOM CORRECTION (ARC®)

Please visit AnthemARC.com for detailed information about using Anthem Room Correction.

The most signicant detriment to the sound of an audio system is almost always the room it resides within—especially true in the realm of bass. Even in a professionally treated sound room, bass can quickly become boomy or anemic. Anthem Room Correction helps audio systems sound their best in any space. ARC oers a robust suite of tools to tame your wild sonic frontier, whether you have a tricked-out home theater, a traditional living room with carpet and thick drapes, or a modern oor plan with large open spaces and acoustically reective furniture and windows.

Have you ever tested the acoustics in an empty room by whistling or clapping? It brings to mind how sound is aected by a room’s size, structure, and contents. Even when using optimally positioned speakers of exceptional quality, the room negatively impacts sound quality considerably. Surfaces such as windows and furnishings and the geometry of the walls, oor, and ceiling add unwanted resonance and coloration, making the bass either boomy or less punchy, voices less natural, and the dialogue less intelligible. The eect on frequency response is typically ±6 dB in the midrange and ±10 dB at low frequencies.

The default correction range, as shown below, is 5,000 Hz. This range can be changed to a higher or lower frequency if desired, although raising it is not recommended. At higher frequencies, the microphone becomes directional, thus aecting measurement accuracy.

Note the rise in the measured and corrected response below 200 Hz. This rise shows the amount of room gain. ARC preserves the natural room gain of the room or allows you to adjust the amount of room gain if you wish.

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.

To compensate for this and to optimize the in-room response of your speakers, Anthem Room Correction measures the output of each speaker relative to the listening area then, through a series of calculations, adjusts its output. Not only does ARC correct peaks and dips in a speaker’s frequency response, but it also preserves the benecial acoustic attributes of a room— attributes based on proven psychoacoustic science (the study of how humans hear and experience sound).

In the sample curves provided here, 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. The black curve represents the target response. In this case, a subwoofer and bass management are also in use.

4.1 USING ARC WITH AN MDA

In addition to correcting the acoustic response of subs and speakers in each zone, ARC also:

• Adjusts the left/right balance of the speakers.

• Sets the crossover point between the speakers and sub-

woofer (do not manually change this after running ARC).

• Adjust the subwoofer’s level relative to the speakers.

• Sets the phase and polarity of the subwoofer relative to

the speakers (requires the additional step of running the Automatic Phase Adjustment tool after uploading corrections to the MDA).

Before using Anthem Room Correction:

• Name the MDA.

• Set up and name the zones.

• Enable subwoofers (if applicable).

To use Anthem Room Correction:

1. Download and install the program from AnthemARC.com.

2. Start the program and select Launch ARC from the rst screen.

3. Select the MDA from the device discovery screen.

4. Select the zone you wish to measure from the drop-

down list.

5. Follow the on-screen instructions to measure the zone,

calculate correction curves, and upload them to the MDA.

6. After uploading the corrections, run the Automatic Phase

Adjustment tool from the Review Summary & Upload screen. This tool sets the phase of a subwoofer to optimize its integration with the speakers.

5. UPDATING FIRMWARE

When connecting to the MDA’s web interface, the MDA checks our server (if there is an active internet connection) and, if an update is available, displays a notication at the bottom of the screen. Alternatively, an update le can be downloaded from our web site and installed later.

5.1 UPDATING FIRMWARE (USING AN INTERNET CONNECTION)

Manually Resetting Network IP Mode to DHCP

If errors occur when adjusting static IP settings, the MDA can be manually set back to DHCP. Using a pin or straightened paperclip, depress the DHCP Reset / Factory Image button for about 1 second. The blue ID LED turns on to indicate the selection of DHCP. It should take a few seconds for the server to reassign an address.

Manually Loading the Factory Image

This function restores the MDA to its original factory image. Any rmware updates you have done are lost and replaced by the version programmed at the factory. The current settings, the saved user settings, and the saved installer settings are

deleted and replaced by the factory default. ARC corrections are also erased from local memory.

To reload the original factory image and remove all settings, set the Master Power switch to O and wait until the lights above the Network connection stop ashing (this may take over a minute if the unit was in standby). Using a pin or straightened paper clip depress and hold the DHCP Reset / Factory Image button while turning On the Master Power switch. Continue to depress the button until the blue ID LED ashes twice. The Factory Image reloads (this takes about a minute). Front panel indicators turn blue and red using a chasing pattern while the reload is taking place.

8. FREQUENTLY ASKED QUESTIONS

HowdoIndtheIPaddressofmyMDA?

We recommend using Anthem’s ARC Genesis software or using a utility called Fing. See section 2.2 for additional details.

I’m connecting my DVD player to the MDA using a TOS input, but even if the disc is playing, I do not hear any sound.

The MDA digital input only supports a PCM stream. Access your DVD player setup menu and change the output format to PCM.

I have a subwoofer connected to the MDA using an RCA jack, but even if I’m playing music with lots of low-frequency content, the subwoofer does not work.

Enable the subwoofer (the default setting is o). See section

2.4 for additional information.

I’m sending commands to the MDA using the serial port, but the MDA does not react.

Make sure to congure your controller to 115200/8-N-1. Make sure to send the terminator “;” at the end of the command. CR/ LF are not required.

I’mconguringapairofspeakersinstereobridgemode

on zones 1 and 2. I have my left speaker on zone 1 and my right speaker on zone 2. My source’s left channel is attached to the Analog 1 left input and its right channel connected to the Analog 2 right input. I only hear sound

fromtheleftchannel.WhatamIdoingwrong?

Inputs and speakers (even bridged speakers) operate independently of one another. Attach your source’s left and right

channels to the Analog 1 inputs and set Zone 1’s Input Source to Analog 1. When in bridge mode, Zone 1 becomes the “master,” so source selection, volume change, tone control, are all done by accessing the Zone 1 panel. All settings in Zone 2 set before selecting Stereo Bridge mode are no longer relevant.

My CD player analog output level cannot be controlled and defaults to a very high level (2 Vrms). When playing music, the MDA seems to be clipping very often. How can

thisbeavoided?

The MDA allows you to change the trim of any source. Select the Inputs pane and set the trim level between -6 dB to -9 dB for the source where your CD player is connected.

How does the MDA work when the On Mode switch is set

toAuto?

When the MDA is in standby, it monitors all analog and digital connectors to check if the unit needs to turn on:

• Analog connectors are monitored for a signal higher than

-60 dBV (1 mVrms).

• Digital connectors are monitored by checking if there is any bit toggling on the coaxial or Toslink inputs. The MDA doesn’t check for a specic level to achieve <1/2W in standby, only activity.

When in operation, the active channels are monitored. When the level drops below -60 dBV (for either analog or digital inputs) for the amount of time programmed in the Auto-O delay, the zone turns o. If all zones are o, the unit will go in standby.
