Dual 12” 2-Way
Powered Loudspeaker
User Manual
Overview
The AT212-MK3 is a very high-output, self-powered, internally processed, bi-
amplified, 2-way, broadrange loudspeaker. The cabinet is lightweight, the
setup is easy and the output is smooth with a natural, musical character. The
remarkable power and efficiency of the AT212-MK3 make it ideal for providers
who want to deliver high sound pressure levels but prefer not to move heavy
cabinets. Intended for use with a subwoofer system to complete a 3-way active
full-range system, the AT212-MK3 has a tall, slim design that allows the HF
horn to stand above crowds when the cabinet is stacked on subwoofers.
The light weight of the cabinet makes stacking by one person possible. The
AT212-MK3 cabinets weigh only 99 lbs. The AT212-MK3 is a vented cabinet that
features two high-efficiency 12” woofers.
The woofers feature 3.5” voice coils, Neodymium magnets, cast aluminum baskets
and ultra-light cones. The compression driver also features a Neodymium motor
structure with a 3” voice coil. It is mated to a 1.4” throat, cast aluminum
horn. The horn is rotatable, providing 80 x 60 degree coverage for multiple
applications including ground stack and horizontal or vertical flying.
The AT212-MK3 is the ultimate in plug and play, with universal voltage
compatibility and no need for any outboard gear, other than a sound source.
The built-in processing features presets that allow it to run in multiple
configurations. Each preset offers advantages that suit specific applications
and preferences.
Power is supplied by an amplifier that can deliver output peaks of 163V, to
provide amazing dynamic resolution and impact. The fully integrated and
comprehensive digital processing ensures smooth response and reliable
operation thanks to meticulous filter alignments and five-stage limiters that
protect the drivers from excessive excursion, thermal overload and clipping.
The amplifier features a large heat sink and 2 temperature-controlled fans to
ensure consistent operation, even under the most extreme conditions.
The cones are waterproofed to protect them from accidental exposure to
moisture such as rain or spilled beverages. Weather resistant, IP65 rated
power connectors, an internally sealed input section and waterproof-treated
cones are provided to allow operation where rain might be encountered.
The cabinet is built from 18mm and 15mm Birch plywood. It features an 18mm
baffle and 18mm top and bottom, with 15mm sides, port walls and braces, all
assembled with dado joinery. The cabinet includes 4 steel bar-handles, 4
internally braced steel M10 fly points and a 35mm (1-3/8”) cast metal pole
socket.
Although the AT212 cabinet is equipped with a 35mm steel pole socket, DO NOT
use this speaker on a tripod or extension pole. This socket is to be used with
a special, short section of pole to prevent it from moving once stacked on a
subwoofer.
The MK3 features an all-new DSP. The comprehensive suite of processing
includes multiple presets, each including multiple protection systems and
limiters to prevent driver overload in as many ways as possible, including
thermal, excursion and clipping. There are five levels of protection that
actively prevent overheating of the voice coil, minimize long-term thermal
compression and limit excursion. Because they operate in 5 different modes,
the limiters are sophisticated enough to have a largely unnoticable effect on
the transient response and allow the subwoofer to deliver peak output safely.
Each preset has a specific high-pass filter frequency and alignment filters
that ensure it’s output is always phase coherent with any BASSBOSS sub. No
matter which preset you choose, your BASSBOSS ubs and tops will always play in
harmony.
The full-range mode, Preset 1, provides response down to 50Hz (-3dB). Each
successive preset filters the lows out at higher frequencies. As low-frequency
demand is reduced, higher sound levels can be achieved, allowing the AT212-MK3
to be used above multiple subwoofers.
Not including Cardioid, there are up to 56 possible combinations when MK3 tops
are used with MK3 subs, but don’t worry, all are compatible. You can’t choose
a “wrong” preset, you simply choose the combination you like best.
The new DSP features an Ethernet interface. This can be used to control the
cabinets from a computer or to load software or firmware updates. The ethernet
connectivity, in conjunction with the new DSP board, will allow signal to be
sent via Milan AVB. (Firmware updates will provide access to this feature.)
Within the software, multiple cabinets can be grouped together, allowing them
to respond to commands simultaneously. This permits the levels of groups of
loudspeakers to be adjusted together, and yet independently from the levels of
other groups of loudspeakers. In addition to individual and grouped level
controls, presets can be loaded and signal levels and temperatures can be
monitored. Each cabinet includes a two-port switch, so multiple cabinets can
be chained on the same data cable.
The MK3 DSP features storage capacity of up to 100 presets, eight of which can
be accessed at the touch of a button with no need for a connected computer.
The eight directly accessible presets are compatible with all the presets in
the MK3 Top Boxes and are also compatible with previous generation tops and
subs.
Quick Start Guide
- Ensure the cabinet is secure and stable.
- Connect signal via the XLR-F input.
- Connect the XLR-M connector to additional subs or tops.
- Connect the mains power and verify the “Ready” LED is lit.
BASSBOSS systems are easy to set up quickly. The best possible results are
achieved consistently because of the integrated nature of the designs. All
BASSBOSS loudspeakers are complete, integrated systems, featuring the cabinet,
transducer, amplifier and a comprehensive suite of processing. Setup is
particularly easy because the products integrate with each other.
Provided the cabinets are physically aligned, any BASSBOSS sub can be combined
with any BASSBOSS top and their outputs will be phase-coherent. This means no
cancellations and no gaps in the response at the crossover frequency,
regardless of which preset is selected.
The on-board BASSBOSS processing allows for the following:
Any BASSBOSS powered subwoofer can be combined with any other BASSBOSS Powered
subwoofer and their outputs will sum coherently. (i.e.: in phase with each
other.)
Any BASSBOSS powered subwoofer or combination of BASSBOSS powered subwoofers
can be combined with any BASSBOSS powered top and their outputs will sum
coherently through the crossover region.
HOWEVER only one model of top should be used at a time. An assortment of
different tops cannot be stacked together and still achieve coherence and
clarity.
The following tops should be used individually, i.e. should NOT be arrayed:
AT312 (Co-axial point-source Main)
DiaMon (Co-axial point-source satellite)
SV9 (2-way monitor with Satellite mode)
The following tops can be used in arrays:
MFLA (Medium Format Line Array, up to 20 cabinets can be arrayed)
AT212 (Horizontally arrayable when necessary)
DV12 (Arrayable in PAIRS ONLY with the upper box of the pair inverted.)
Outboard Processing Warning
Third-party outboard processing (Drive Racks, etc.) are not recommended and
are not necessary with BASSBOSS MK3 series powered loudspeakers. Outboard
processing will not improve, and will very likely degrade the sound quality,
reliability and output capacity. Using external processing inappropriately can
cause driver damage that is not covered by warranty.
The internal processing can accomplish everything an external processor could
accomplish, butwithout degrading the sound quality and without putting
components at risk. Before considering using an outboard processor, contact
BASSBOSS customer service with your use-case scenario for assistance in
setting up the internal processing to achieve your goals.
Setup Procedure
Once the the cabinet is in the desired location, signal cables should be
connected via the XLR-F input.
It’s recommended to run balanced signal cables to minimize the chance of noise
and ground-loop hum.
The incoming signal should be unprocessed because all the necessary processing
is done in the builtin DSP.
The signal should be run directly from the outputs of a mixer or controller.
The XLR-M connector provides a full-range, unprocessed, pass-through
connection to additional cabinets. This output can be connected to additional
subs or tops. Up to 12 cabinets can be connected on a single output from a
mixer or controller.
Connecting the mains power. The power connector is a Neutrik PowerCON TOP
waterproof type. The power connector inserts with the silver tab rotated
counter clockwise from vertical, at about the 10:00 position, and once
inserted, rotates clockwise to the 12:00 position to lock in place. Once
locked, this connector is waterproof.
This connector also serves as the power switch. To disconnect and remove the
connector, pull back on the silver tab to unlock it and rotate it counter
clockwise. Once rotated to the insertion angle, the connector can be removed.
When connecting and disconnecting, no force should need to be applied. If the
connector doesn’t insert and rotate smoothly, either it’s in the wrong
position or it’s damaged and should be replaced. Always use a grounded outlet.
The supplied power cord includes a standard grounding NEMA 5-15 (Edison)
120-Volt US wall plug. In unfamiliar locations it’s recommended to verify the
correct wiring of outlets before powering your system.
It’s highly recommended to connect all signal and power cords to the speakers
before plugging the power cords into mains outlets. When your speaker is
powered on, you’ll see all the indicator lights turn on and then show the
system’s current status.
Although the AT212 cabinet is equipped with a 35mm steel pole socket, DO NOT
use this speaker on a tripod or extension pole. This socket is to be used with
a special, short section of pole to prevent it from moving once stacked on a
subwoofer.
Operation & Controls
There are 2 controls on the amplifier.
-
Input
This knob adjusts the input level from -72dB to -0dB. To avoid distortion and clipping, make sure the input signal doesn’t exceed +22dB and the output doesn’t reach clipping before you achieve the desired sound level.
While the amplifier has built-in limiters and safety features to protect itself and the speaker, it can’t protect the speaker from distorted incoming signals. The amplifier will simply amplify the clipped signal, which can do the same damage as clipping an amplifier. Since it’s essentially impossible for these amplifiers to clip, signal-level clipping is the most common cause of damage to these speakers. If you hear distortion, lower the input level right away. -
Preset Select
Pressing the Preset Select button cycles through presets 1-8, and pressing it again after preset 8 returns to preset 1. Each preset includes all necessary low-pass and high-pass filters at the selected frequencies and all the necessary alignments to maintain phase coherence in the crossover range when used with other BASSBOSS powered speakers.
Presets help you fine-tune the balance between the subwoofers and top speakers. More details on the different combinations are on page 7.
Indicator LEDs
Indicator LEDs – Left side, bottom to top:
Ready: Indicates that power is on and the system is ready to play.
Signal: Indicates the presence of input signal.
-12dB: Indicates there is 12dB of headroom remaining before reaching maximum output.
-6dB: Indicates there is 6dB of headroom remaining before reaching maximum output.
Limiting: Indicates one of the channels is reducing the incoming signal level
to prevent overdrive.
Overheat: Indicates the amplifier is reducing output to prevent shut-down from
overheating.
Protect: Indicates the amplifier is shut down due to a condition that could
cause further damage.
The Protect LED also is engaged when the system has been muted via the
software.
Comm Link: Indicates communication is active on the LAN connection(s).
Indicator LEDs, Right Side, Bottom to top:
Presets 1-8 – The illuminated LED indicates the corresponding preset is
loaded.
How to Use the Presets
Setting the low-pass filter frequency on the subwoofer to match the top
cabinet’s high-pass filter frequency and balancing their levels will achieve
the smoothest sound across the frequency range.
There are no incompatible combinations.
Selecting high numbered presets on subs with low-numbered presets on tops will
result in increased system output in the overlap range, which can be helpful
in some situations but can also result in a “boomy” sound.
When the subwoofer levels are to be run higher than tops levels, (which is
almost always) the effective crossover moves higher in frequency. If you
intend to run your system “bass-heavy ” it’s recommended to run lower-numbered
presets on the subs and higher-numbered presets on the tops to avoid an
excessively “boomy” sound.
Selecting low-numbered presets on subs with high-numbered presets on tops may
result in a lack of “punch” in certain combinations. This is most likely when
not enough level is available from the subwoofer(s).
When not enough output is available from the sub(s), using a preset
combination with overlap can help provide a little more bass level but it does
limit the maximum level of the tops due to the added demand for low-
frequencies from the tops.
It’s recommended that you try several, if not all, combinations when first
setting up to determine which combination works best in each environment. You
will likely choose different combinations for wood floors, concrete floors and
outdoors.
Experiment with different combinations to dial in your preferred combination
in different environments. Pre-Installed Onboard Presets
High-pass and low-pass filters with included phase compensation.
Preset 1: 45Hz high-pass filter
Recommended for use when no sub is available.
Peak output is restricted to prevent low frequencies damaging the loudspeaker.
- Preset 1: 45Hz high-pass filter.
- Preset 2: 55Hz high-pass filter
- Preset 3: 65Hz high-pass filter
- Preset 4: 75Hz high-pass filter
- Preset 5: 85Hz high-pass filter
- Preset 6: 95Hz high-pass filter
- Preset 7: 105Hz high-pass filter
- Preset 8: 115Hz high-pass filter
With their levels matched, when the low-pass filter frequency selected on the
subwoofer is matched with the high-pass filter frequency selected on the Top
cabinet, the smoothest frequency response should be achieved.
Additional presets are accessible through software. See “How to Use the
Presets” section for more information. New presets will be available for
download at bassboss.com/software as they are
developed.

Power Distribution
Connect no more than one 5000W or two 2500W subwoofer amplifiers to a single
20A circuit. If you need to share circuits, don’t exceed two BASSBOSS single-
driver subwoofers or one double-driver subwoofer, along with one or two top
speakers, on the same circuit.
Although amplifiers for tops and subs may be specified to have the same “power
” capacity, in practice, amplifiers used for tops applications tend to draw
significantly less current. Subwoofers draw far more current than tops due to
the demands for bass level and the duration of the notes.
All MK3 amplifiers can operate on mains supply from 100 to 250VAC. To connect
to voltages other than 120V, a different mains connector plug must be used.
Contact your salesperson for information about purchasing cables for alternate
voltages.
Pass-through Power connections can be used to power additional cabinets. With
optional True 1 TOP cables, power can be linked between subs and tops. Do not
connect equipment that will draw more than 15A on a single power outlet.
Contact your salesperson for information about linking power cables.
Avoid powering all subwoofers on the same circuit. Instead, use separate circuits for each subwoofer and top speaker combo to help prevent overloading a single circuit and tripping a breaker.
Troubleshooting
If, after following the previous instructions for setup, you have no output
from the loudspeaker:
Verify that the green Ready LED is lit. If NOT lit, check the following:
- Is the power cord plugged into a live outlet?
- Is the Neutrik powerCON connector rotated into the locked position?
If the green Ready LED is lit, check the following:
-
Is the red Protect LED illuminated? The unit may be in protect mode or set into mute via software.
-
Is the signal cable connected to the input?
-
Is the signal cable connected to an operating output at the other end?
-
Is there signal flowing to the input? Check the integrity of the cable against a different cable.
-
Is the volume knob turned all the way down or at a very low level?
-
Is the signal flowing to the input full-range?
Filters in the signal may remove the operating frequencies of the loudspeaker receiving them. -
If you’re connected via LAN, check the level and filter settings in the software.

Safety Information
Important information regarding safety and the use of your loudspeakers:
To prevent potentially dangerous exposure to high levels of acoustic pressure,
never stand in the immediate vicinity of loudspeakers driven at a high level
without hearing protection. Professional loudspeaker systems are capable of
causing sound pressure levels detrimental to human health.
When a transducer capable of producing high sound levels is being used, it is
necessary to wear ear plugs or protective earphones to prevent hearing damage.
Even seemingly non-critical sound levels (from approximately 95 dB SPL) can
cause hearing damage if people are exposed to it over a long period. Anyone
exposed to these levels should use appropriate hearing protection devices.
System and venue owners and operators are encouraged to make hearing
protection devices available to all customers and staff members.
In order to prevent accidents when setting up the loudspeakers or loudspeaker
stands, make sure they are standing on a firm surface. Ensure that all
additional hardware, fixings and fasteners used for installation or mobile
deployment are of an appropriate size and load safety factor.
Only use included, factory installed, internally secured M10 fly points when
supporting cabinets. (Not all models include these features.) Only use
appropriately load-rated hardware. Never hang loudspeakers from handles. Never
drill or screw into cabinets to attach lifting points.
Pay attention to the manufacturers’ instructions and to the relevant safety
guidelines. Regularly check the loudspeaker housings and accessories for
visible signs of wear and tear, and replace them when necessary. Regularly
check all load bearing bolts in the mounting devices.
Caution: Loudspeakers produce a static magnetic field even if they are
not connected or are not in use. Therefore make sure when erecting and
transporting loudspeakers that they are nowhere near equipment and objects
which may be impaired or damaged by an external magnetic field.
A distance of 3 feet (1m) should be maintained between loudspeakers and
sensitive equipment such as CRT monitors or magnetic storage media.
Never attempt to carry out any operations, modifications or repairs that are
not expressly described in this manual. Contact your dealer or BASSBOSS
support if the product is not functioning properly. The audio system must
comply with current local standards and regulations regarding electrical
systems.
For installation purposes, BASSBOSS strongly recommends that this product be
installed by a qualified, professional installer who can ensure correct
installation and certify that it is installed in compliance with the
regulations in force.
