The lightweight and efficient design make it ideal for providers who require high output but prefer not to move heavy cabinets.

The AT212-3K is intended for use with a subwoofer system to complete a 3-way active full-range system. Its tall, slim design allows the HF horn to stand above crowds when stacked on subwoofers. Additionally, the lightweight cabinet makes stacking easy for one person.

The cabinet is built of 15mm Baltic Birch plywood and features an 18mm baffle with dado joinery. It has 4 steel bar handles and a 15-degree side angle trapezoid shape. The cabinet is equipped with 5 handles and 8 fly points, offering 80 x 60 degree rotatable coverage for various applications including ground stack and horizontal or vertical flying.

Weatherized versions are available for outdoor installations. Optional features include rack-mounted amplification, waterproof input connections, fiberglass underlaid finish, silicone sealed gaskets, stainless steel grill and hardware, and a hydrophobic grill cloth.

The AT212-3K cabinets can be combined in arrays of 3 or more cabinets, allowing for flexible coverage options. The horn can be rotated, and the boxes can be packed side-by-side to form arrays that cover 90, 120, 150, 180 degrees, and more.

The cabinet is finished in an extremely rugged, black polyurethane coating for durability. The drivers are protected by a black powder-coated, perforated steel grill, and the amplifier is recessed into the back of the cabinet for added protection during transportation.

The amplifier consists of 2 channels with a total power output of 3,000W. It features high dynamic power capacity with 150 Volts peak output per channel and high damping of >10000:1. The amplifier utilizes an efficient, PFC power supply and class D output topology, offering exceptional dynamic resolution, detail, and precise control. It also has low current draw and light weight relative to its output capacity.

All the necessary processing for linear frequency response and phase coherent operation is pre-programmed into the DSP. BASSBOSS loudspeakers provide plug- and-play operation and multiple limiter systems that make the system virtually indestructible.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.

Setup Instructions

Place loudspeaker in the desired location. Ensure that it is secure and stable.
Rotate the input attenuator knob counter-clockwise to the lowest setting.
Connect signal via the XLR input jack.
Connect the amplifier module’s power supply cord using the blue PowerCON connectors. To insert, align the indexing tabs on the PowerCON connector, insert into socket and rotate clockwise until the latch catches.
Connect the electrical plug to a power source. Check that the “Ready” LED is illuminated.
Select the desired preset via the PRESET SELECT button.
Rotate the input attenuator clockwise to achieve the desired sound level.

Controls

Preset Select: The AT212-3K compact full-range loudspeaker’s DSP is equipped with 4 presets. All four presets contain limiter settings to ensure safe operation. The presets are accessed via the preset
select button on the amplifier interface, between the XLR input and output connectors. When the button is pressed, each preset loads in sequence, from 1 to 4, and then cycling back to 1. A green LED
indicates the active preset.
Gain: The level knob provides a range of control from OFF to +12dB within each preset.

Indicators:

Ready – Green LED – Indicates that the amplifier has power and is operational.
Signal – Green LED – Indicates the presence of signal reaching the amplifier inputs.
Temp – Amber LED – Indicates the amplifier is actively reducing level to prevent overheating.
Limit – Red LED – Flashing – Indicates that the loudspeaker is being overdriven.
Limit – Red LED – Solid or rapid blinking – Indicates amplifier is in protect mode.

Preset Functions

Preset 1: Stand-alone Full-Range Operation. 45Hz high-pass filter. Recommended for use when no sub is available. Peak output is restricted to prevent low frequencies damaging the loudspeaker.
Preset 2: Intermediate Stand-Alone setting, 60Hz high-pass. Recommended for use with a single sub or when subwoofers are separated from the AT212-3Ks, such as when subs are center-placed.
Preset 3: Intermediate High-Output setting. 75Hz high-pass. Recommended for use when single subwoofers are co-located with the AT212-3Ks, such as if the AT212-3Ks are on a speaker pole above a subwoofer or on a tripod adjacent to a subwoofer.
Preset 4: Maximum SPL Setting, 90Hz high-pass. Recommended for use when outdoors, in larger venues and/or when multiple or larger subwoofers are co-located with the AT212-3Ks.
Presets 2, 3 and 4 allow the AT212-3Ks to be combined with various subwoofer configurations and allow the sound to be tailored to different environments. It is recommended to listen to the appropriate presets in each new setting and choose the one that works best in that environment.
System Setup Addendum: When connecting multiple BASSBOSS loudspeakers in a system, signal can be passed through from one powered loudspeaker to another using balanced, shielded XLR cables. No processing is applied to the signal as it passes through from the input to the output connectors in each loudspeaker. Signal can be routed in any sequence because each loudspeaker receives a full-range signal and applies the necessary processing in order to operate as part of the overall system. It is recommended to run signal to the nearest box first and patch to the next nearest box in sequence.

Troubleshooting

If after following the above instructions for setup you have no output from the loudspeakers, please check the following: Verify that the green power (PWR) LED is on. If not, check the following:

Is the power cord plugged into a live outlet?
Is the Neutrik PowerCON connector rotated into the locked position?

If the power LED is on, check the following:
Is the green “signal present” LED (SIG) illuminating? If not:

Is the signal cable connected to the input?
Is the signal cable connected to an operating output at the other end?
Is the signal flowing to the input? Check the integrity of the cable.

Safety Information

Important information regarding safety and the use of your loudspeakers:
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB SPL) can cause hearing damage if people are exposed to it over a long period. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones.

See the manual technical specifications to know the maximum sound pressure level.

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.
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 BASSBOSS support if the product is not functioning properly. Do not attempt to repair the product – We can help!
BASSBOSS strongly recommends 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.
The entire audio system must comply with the current local standards and regulations regarding electrical systems.

Important Notes

To prevent the occurrence of noise on signal cables, use shielded cables only. Avoid routing signal cables close to equipment that produces high-intensity electromagnetic fields such as transformers, power cables and loudspeaker wires. Do not coil excess power cable. Do not coil or wrap power cables and signal cables together.
