Product Usage Instructions
Spikes & Feet
Use on wooden or hard floors:
The foot comes fully assembled for use on hard floors. To
install, screw the feet fully into the 4-threaded inserts in the
underside of the cabinet.
Use on carpeted floors:
If you have carpeted floors or prefer to use spikes, screw the
spike into the foot assembly. For thick-pile carpets, remove the
soft polymer pad from the foot to ensure the spike goes all the way
through the carpet into the floor. Make sure there are no hidden
wires under the carpet that could be damaged by the spikes.
Levelling the speaker:
Place the cabinet in your desired location and check that it is
level on all sides. If it is slightly uneven, unscrew the main
threaded assembly at the lowest point and check again. Repeat this
process until the cabinet is fully level. Use the locking nut on
the foot to fix the foot in place and prevent unwanted
vibrations.
Controls and Connections
1 – Encoder:
Press the Encoder to wake up the Subwoofer and select options
within the Subwoofer’s menu system. Turn the encoder to scroll the
menu and adjust the volume, Low Pass Filter settings, and EQ
presets.
2 – Screen:
The screen displays the Anthra menu for setup using the encoder.
Refer to page 10 of the manual for more information on the menu
system layout.
3 – Factory Reset:
To perform a factory reset of the Anthra subwoofer, ensure it is
switched on and press and hold the Factory Reset button for 5
seconds. You can use a thin or pointed object to access the
button.
4 – RCA Line Level Inputs:
For connection to a 2 channel/stereo amplifier system, use a
pair of high-quality signal cables from the pre-out section of an
amplifier. If connecting from an AV receiver or processor, use a
single subwoofer cable into either of the inputs. Note that cable
lengths should not exceed 10 meters to avoid interference from
other electrical appliances.
5 – RCA Line Level Outputs:
These outputs are used to feed additional subwoofers or power
amplifiers from the Anthra subwoofer through a “daisy chain” type
connection. The outputs do not provide filtering or amplification.
Ensure there is a signal into the RCA inputs for the linked outputs
to work. Again, cable lengths should not exceed 10 meters to avoid
interference.
6 – 12 Volt Trigger Input:
This input allows external power control from an AV
amplifier/receiver to the Anthra Subwoofer. Monitor Audio
recommends using this function, and a lead is supplied for this
purpose. The 12-volt signal is generated by the AV amp/receiver and
tells the Subwoofer to turn on from standby mode. This feature
provides a more accurately controlled auto On/Off function and is
more energy-efficient.

Spikes & feet
Use on wooden or hard floors The foot comes fully assembled for use on hard floors. All that is required is fixing into the bottom of the cabinet. This is achieved by simply screwing the feet fully into the 4-threaded inserts in the underside of the cabinet.
Use on carpeted floors For carpeted floors, or where spikes are appropriate, the spike can be screwed into the foot assembly. If your carpet has a very thick pile, remove the soft polymer pad from the foot to ensure the spike goes all-the-way through the carpet into the floor.
Please ensure there are no hidden wires under the carpet that could be damaged by the spikes.
Levelling the speaker Place the cabinet in your desired location, and check that it is level on all sides. If it is slightly uneven, unscrew the main threaded assembly at the lowest point and check again. Continue this process until the cabinet is fully level. Use the locking nut on the foot to fix the foot in place and to stop any unwanted vibrations.

Controls and connections
1 – Encoder Press the Encoder to wake up the Subwoofer and to select options within the Subwoofers menu system. Turn the encoder to scroll the menu and to change the volume, Low Pass Filter settings, and EQ presets in the menu.
2 – Screen Displays the Anthra menu for setup using the encoder. Refer to page 10 for more on the menu system layout.
3 – Factory Reset With the subwoofer switched On, press and hold for 5 seconds to perform a factory reset of the Anthra subwoofer. To access the button use a thin or pointed object.
4 – RCA Line Level Inputs For connection to a 2 channel/ stereo amplifier system, connection should be provided by a pair of high-quality signal cables from the pre-out section of an amplifier. Connection from an AV receiver or processor should be made using a single subwoofer cable into either of the inputs. NOTE: Cable lengths should not exceed 10 metres to avoid interference from other electrical appliances.
5 – RCA Line Level Outputs To be used to feed additional sub-woofers or power amplifiers from the Anthra subwoofer by `daisy chain’ type connection. The outputs are link-out only connections and do not provide any form of filtering or amplification. There must be a signal into the RCA inputs for the linked outputs to work. NOTE: Cable lengths should not exceed 10 metres to avoid interference from other electrical appliances.
6 – 12 Volt Trigger Input ~ Centre Pin Tip = +12Vdc For external power control from an AV amplifier/ receiver to the Anthra Subwoofer. Monitor Audio recommend using this function and a lead is supplied. This 12 volt signal is generated by the AV amp/receiver and tells the Subwoofer to turn On from standby mode. This allows a more accurately controlled auto On/Off function, and is far more energy efficient.
7 – Balanced LFE Input (Female XLR Type) To be used when connecting to the balanced output on the amplifier. This is the best method of connection when using long runs of cables (over 10m up to 100m). A balanced connection provides a much better, almost noise free method of connection over RCA connectors.
8 – Balanced LFE Output (Male XLR Type) To be used to feed additional sub-woofers or power amplifiers from the Anthra subwoofer by `daisy chain’ type connection. This is the best method of connection when using long runs of cables (over 10m, up to 100m). A balanced connection provides a much better (almost noise free) method of connection over RCA connectors. The output is a link-out only connection and does not provide any form of filtering or amplification. There must be a signal into the XLR input for the linked output to work.
9 – IEC Mains Input Socket The subwoofer is supplied with a three-pin mains input socket for connection to the mains supply. Use ONLY the appropriate IEC mains lead provided with the product.

Setting up
Initial set-up Follow the steps to get started setting up your Anthra Subwoofer. More detail for each step is also given in the corresponding sections. Leave the subwoofer unplugged from the mains until all signal cables are connected. 1. Position subwoofer, all features and settings can be configured using the MaestroUnite app or
from the back of the subwoofer. 2. Connect the signal cables based on your system, refer to the AV or Stereo System section
below. 3. Connect the IEC mains lead provided and switch the subwoofer On by pressing the encoder. 4. Download MaestroUnite, refer to page 12. 5. Connect to MaestroUnite.
Positioning The subwoofer should be sited in the most suitable position, preferably not directly in the corner of a room as this may cause excessive bass boom. Once a desirable position is achieved it is important to check if the cables are long enough to reach comfortably without being under tension. If using the RCA inputs, cables should be less than 10 metres to avoid interference.
Audio Connections When using a mono subwoofer output from your amplifier/ receiver, connection is made by RCA type connectors to the left or right input or a balanced XLR connection. If a stereo RCA connection is preferred, connect to the left and right RCA inputs from the pre-amp outputs on your source amplifier. When daisy chaining to an additional product ensure the output from the Anthra Subwoofer is connected to the corresponding input on the Anthra Subwoofer. For example, use the left RCA input and left RCA output. Not the Left RCA input and balanced XLR output.
Do not connect or disconnect the signal leads with the Anthra Subwoofer switched on.
Power To power on the subwoofer connect the supplied IEC power cable and press the encoder on the amp panel. The Monitor Audio Logo will briefly appear on the screen followed by the menu system. The Anthra subwoofer can also be set to wake from standby using Music Sense or the 12v Trigger from the MaestroUnite app.
AV System
By default the Anthra LPF is bypassed, we recommend setting the crossover at the receiver or amplifier. This is usually done as part of the automatic setup on the AV receiver or amplfier. It is recommended to double check the settings of the automatic setup to ensure the levels and crossover settings are correct.
Stereo System
When connecting using this method, you use the LPF settings in the Anthra Subwoofer to allow only the bass frequencies to be played. This can be done using the encoder or the MaestroUnite app. Depending on your speakers this setting will vary, please refer to the table as a guide for approximate crossover settings. Experimentation is highly recommended to find the best setting for your speakers and personal tastes.

Care & maintenance
Upkeep of cabinets The finish of the cabinet can be maintained by regular dusting using a soft or micro fibre cloth. The drive units should only be cleaned with a damp cloth, if more than normal dusting is required. Be careful not to damage the driver units whilst cleaning. Never use solvents or aggressive cleaning/polishing agents on your Anthra Subwoofer. When in doubt, test the cleaning product on an inconspicuous area on the cabinet, and let it sit for several days before committing to its use on visible portions of the cabinet.
