Overview

The DiaMon-MK3 is a high-output, point-source loudspeaker that can make your life easier thanks to its remarkably small size. This very compact and portable system provides impressive output without ever having to lift a large, heavy cabinet.

In terms of output SPL relative to size, the DiaMon-MK3 has virtually no competitors. The compact, high fidelity and high output DiaMon-MK3 continues the BASSBOSS tradition of delivering remarkable output capability and outstanding sound quality. Achieving this level of performance from such a small enclosure is made possible by making decidedly different design and component choices.

The cabinet is made from Birch plywood, which is strong and solid, and the small size makes it very easily portable. The small size is made possible by the use of a co-axial driver in a sealed enclosure. With the high-frequencies exiting co-axially through the center of the woofer, no extra space is required for the addition of a high-frequency horn.

The low and midrange frequencies are produced by a high-sensitivity 12″ cone woofer with a 3″ voice coil and a neodymium magnet. The same magnet is used for the 3″ diaphragm high-frequency compression driver, the 1.4″ output of which passes through the woofer’s pole-piece. The inner surface of the polepiece is machined into the shape of a horn. The woofer cone is the continuation of that horn, making it possible to generate very high output from a very small total surface area.

The resulting coverage pattern is 80 degrees conical, permitting a large coverage area and a great deal of placement options. A significant advantage of co-axial loudspeakers is the consistency of their offaxis response. Aside from delivering a more consistent and intelligible sound field, this also makes them much more resistant to feedback.

The amplifier features a Class D SMPS with PFC, providing two channels, 900W LF and 300W HF. Eight on-board presets allow for a variety of configurations at the touch of a button, and LAN connectivity allows access to virtually unlimited preset combinations.

On-board presets provide a variety of high-pass filters to suit full-range operation through a variety of settings that maximize SPL when used with a subwoofer. The sealed enclosure provides the flexibility to choose between low-frequency extension or high-SPL operation from the same compact loudspeaker.

When used with subs in high-SPL presets, remarkably large events and venues can be covered with these tops that measure just 14″ x 14″ x 11″ and weigh less than 30 pounds.

The proprietary BASSBOSS processing ensures exceptional sound quality thanks to its premium quality, high-fidelity electronics. Its ultra-low noise CODECS, 96kHz sampling rate processor and high resolution amplification are some of the finest in the industry.

BASSBOSS loudspeakers are protected for safe, high-power operation. Optimized signal processing, premium quality drivers, power-matched amplification and comprehensive protections ensure that no matter the demand, they keep their cool, keep their character and keep on working.

The Birch wood cabinet features a 35mm steel pole socket and is finished in durable, high-pressure polyurea coating. Power, signal and data connectors are hidden on the bottom panel, providing a clean, tidy look that maintains the compact aesthetic.

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 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 Power CON 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.

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.

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 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 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.

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

All presets include phase compensation for integration with BASSBOSS subwoofers.

Each preset moves the operational range of the speaker up by 10Hz, starting with the lowest frequency of 50Hz in Preset 1. Higher SPL is available from higher presets.*

Preset 1: 50Hz (Maximum LF extension)
Preset 2: 60Hz
Preset 3: 70Hz
Preset 4: 80Hz
Preset 5: 90Hz
Preset 6: 100Hz
Preset 7: 110Hz
Preset 8: 120Hz (Maximum SPL Capability)

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.

When the Subwoofer level is elevated above the Tops level, a higher numbered preset can be chosen on the Top cabinet to prevent an output peak in the crossover/overlap range.

Additional presets are accessible through software.
See “How to Use the Presets” section for more information.

• (Greater demands for lower frequencies require greater restrictions on maximum output to prevent driver damage.)

Power Distribution

Connect no more than one 5000W or two 2500W subwoofer amplifiers to a single 20A 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.

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.

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.

With optional True 1 TOP link cables, power can be linked between subs and tops. Using these, DiaMons can be powered via the pass-through power connections all BASSBOSS subwoofers. (Do not connect equipment that will draw more than 15A on a single power outlet.) Contact your salesperson for information about ordering linking power cables.

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 power CON 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.

The audio system must comply with current local standards and regulations regarding electrical systems.

Important Notes

Shielded data cables must be used.

To minimize the occurrence of noise and interference, always use shielded signal cables. Avoid routing signal or data 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 or data cables together.
