DV12-MK3 Single 12”
Powered Loudspeaker
User Manual

Overview

The DV12-MK3 uses a line-array derived 1.4” throat isophasic wave guide instead of a conventional horn. Coupled to the wave-guide is a 3” diaphragm, Neodymium motor compression driver.. This combination provides effortlessly high SPL over very wide and consistent horizontal coverage of 120° with a tight vertical pattern of 20°. This extends high frequency intelligibility farther than a conventional horn and allows for two arrayed cabinets to provide coherent, linearray style performance.
The lower frequencies are produced by a 12” woofer that features a Neodymium magnet for light weight and high efficiency, a 4” voice coil for high power handling, and a symmetrical, long-excursion suspension for accurate and extended bass response. So much bass response that it could easily serve as a subwoofer driver.
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 peaks, and also from thermal overload, by monitoring real power output over time. The amplifier features a large heat sink and 2 temperaturecontrolled fans to ensure consistent
operation under even the most extreme conditions.
The DV12-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 processing features presets that allow it to run in multiple configurations. The fullrange mode,
Preset 1, provides response down to 40Hz (-3dB). Each successive preset filters the lows out at higher frequencies, allowing the DV12-MK3 to be perfectly integrated with various types and sizes of subwoofers.
Each preset has a specific high-pass filter frequency and alignment filters that ensure it’s always phase coherent with any BASSBOSS sub. As low-frequency demand is reduced, higher sound levels can be achieved. In the higher presets, this allows each DV12 to provide enough mid-high power for multiple subwoofers. The DV12-MK3 can be combined with any BASSBOSS subwoofer because all the presets are programmed to align with all the subs. Each preset offers advantages that suit certain applications and preferences. No matter which preset you choose, your BASSBOSS subs and tops will always play in harmony.
The cabinet is made from 15mm Birch and features bracing for additional rigidity. The design incorporates a 4-degree down-angle that ensures the even distribution of high-frequency energy from the front to the back of a venue when the DV12-MK3 is placed at the appropriate height on a tripod or support pole. Additional features include a 35mm (1-3/8”) steel pole socket, eight fly points and six handles. The amplifier is recessed from the back of the cabinet to protect it in transit. A perforated steel grille protects the woofer, and its progressive perforation pattern serves to broaden midrange dispersion. The high-frequency lens and port are left clear of the grille to minimize reflections and air flow noise that could compromise sound quality.
Should you ever need more sound than can be produced by one DV12-MK3 per side, their invertible array feature allows the perfect summing of two speakers, which provides a big increase in output and projection without compromising the crystal clarity. This is an additional benefit of the line-array waveguides. When two DV12-MK3s are vertically stacked with the HF lenses adjacent, (top cabinet inverted) the high-frequency sections of the two boxes sum perfectly, as they would in a line-array, while the low-frequency sections sum in a column for improved low-frequency directivity and greatly increased output. Compared to conventionally arrayed boxes, this results in 3dB more SPL and much smoother response in the high-frequency ranges.
The MK3 features an all-new DSP. The comprehensive suite of processing includes high-pass and low-pass filters as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible, including thermal, excursion and clipping. The five levels of protection 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.
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 DSP board allows 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 multiple 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

1. Ensure the cabinet is secure and stable.
2. Connect signal via the XLR-F input.
3. Connect the XLR-M connector to additional subs or tops.
4. 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 without 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 True1 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 DV12 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.

1. 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 incoming signal 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.

2. 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.

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: 40Hz high-pass filter
Recommended for use when no sub is available.
Peak output is restricted to prevent low frequencies damaging the loudspeaker.

• Preset 2: 50Hz high-pass filter
• Preset 3: 60Hz high-pass filter
• Preset 4: 70Hz high-pass filter
• Preset 5: 80Hz high-pass filter
• Preset 6: 90Hz high-pass filter
• Preset 7: 100Hz high-pass filter
• Preset 8: 110Hz 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.

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, amplifiers  used for tops applications tend to draw significantly less current. Subwoofers draw far more current than tops due to the demands for level and the duration of the notes.
The 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:

1. Is the power cord plugged into a live outlet?
2. Is the Neutrik powerCON connector rotated into the locked position?

If the green Ready LED is lit, check the following:

1. Is the red Protect LED illuminated? The unit may be in protect mode or set into mute via software.

2. Is the signal cable connected to the input?

3. Is the signal cable connected to an operating output at the other end?

4. Is there signal flowing to the input? Check the integrity of the cable against a different cable.

5. Is the volume knob turned all the way down or at a very low level?

6. Is the signal flowing to the input full-range?
   Filters in the signal may remove the operating frequencies of the loudspeaker receiving them.

7. 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.
Always use the included, factory installed, internally secured M10 fly points when supporting the cabinets. 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.
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.
