Frequently Asked Questions - AT312-MK3 BASSBOSS
What is the power rating of the AT312-MK3?
The AT312-MK3 has a built-in 1200 W RMS class D amplifier, providing ample headroom for professional sound reinforcement.
Can I use the AT312-MK3 as a floor monitor?

How do I connect the speaker to a mixer?
Use a balanced XLR or TRS cable from the mixer output to either combo input on the AT312-MK3. For daisy-chaining, connect additional speakers from the XLR link output.
What should I do if there is no sound output?
First check the power indicator to ensure the speaker is on. Then verify that the input signal is present, the cable is not damaged, and the gain controls are not fully turned down.
Does the speaker have a built-in crossover?
Yes, the AT312-MK3 includes a DSP-controlled electronic crossover that actively filters the high and low frequency sections for optimal performance.
How do I clean the speaker cabinet?
Use a soft dry cloth to wipe the exterior. Avoid using water or liquid cleaners, as they may damage the coating or enter the grille and harm the drivers.
What is the recommended speaker stand height?
Place the speaker on a stand with the horn at ear level for the audience, typically around 1.8 to 2.1 meters (6-7 feet) from the ground.
Can I use two AT312-MK3 speakers for a stereo setup?
Absolutely. Pair two AT312-MK3 speakers with a stereo mixer or controller for a full-range stereo PA system. Each speaker has its own amplifier and DSP.
What kind of power cord does the speaker use?
The AT312-MK3 uses a standard IEC C14 power inlet with a detachable cord, similar to most professional audio equipment.
How do I protect the speaker from overloading?
The internal DSP limiter protects the drivers from excessive levels, but it's still advised to avoid clipping the input signal and to keep the gain structure properly matched to the mixer.
