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.

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.

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).

12

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.

Powered by Zone 2 (4, 6, or 8): Congures two consecu-

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.
