The DiaMon 112 is a very compact, high-output, self powered loudspeaker. It features a 12” woofer and a co-axial 1.4” exit
compression driver that plays through the center of the woofer, making it a true point-source cabinet. Both the woofer and
tweeter coils share the same magnetic structure to keep size and weight to a minimum.
Because the tweeter exits through the middle of the woofer, the extra area that the tweeter would ordinarily take up on the
front of the loudspeaker is eliminated, which helps make the DiaMon extremely compact. It’s barely bigger than a 12” woofer
but also incorporates a 1.4” exit compression driver with a 3” voice coil. The DiaMon 112 includes a 1500-watt Class D Powersoft
amplier with built-in digital signal processing, is bi-amped and has a full complement of protections, limiters and equalizers
that ensure consistent, accurate and reliable operation. It is fully self-contained and needs no more than power and signal to
be ready to go.
Even though the box is very small and very lightweight, there is nothing small or lightweight about its performance.
This box is literally packed with the best components and technology money can buy, the whole point of which is to do more
with less. The output of this little box is totally out of proportion to its size. It’s extremely loud, but it’s capable of being loud,
not struggling to be loud. It sounds much bigger than it looks and has the ability to maintain crystal clarity even at the upper
limits of its very remarkable capabilities.
The DiaMon 112 is a mid-high loudspeaker, so in order to deliver the BASSBOSS experience with full system sound it’s best
to combine it with a very powerful BASSBOSS subwoofer. It has the output to keep up with several subs and for system usage
is intended to be mounted on a pole-stand above one or more BASSBOSS subs. Used with a subwoofer system, the DiaMon is
an extraordinarily size-conscious and yet very powerful main speaker.
Any speaker that has the tweeter horizontally or vertically oset from the mid-frequency driver produces very dierent
response as one moves through its coverage area from the tweeter side to the woofer side. This is due to the dierent
distances the sound has to travel to reach the ears. Due to the co-axial construction the path length dierence between lows
and highs is the same in any direction, allowing extremely consistent o-axis response regardless of which direction you move
away from directly on center.
The DiaMon 112 has a unique angle-cut corner that allows it to be placed on a table and used as a DJ monitor without pole-
mounting. It also has a securely attaching threaded pole-mounting system for when it is used attached to a socket-equipped
BASSBOSS subwoofer or on a similarly equipped tripod stand. An adjustable mount bracket is also available for alternative
placements and for permanent installations on walls or ceilings.
As a main speaker, the DiaMon 112 can be used with two double 18” subwoofers and deliver all the mid-high you need to keep
up with them. As a DJ monitor it provides tight, punchy performance and doesn’t distort at high levels. As a live reinforcement
speaker, this versatile box provides consistent sound quality over a wide dispersion pattern with excellent resistance to feedback.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specications that are inated over what can actually be
achieved. BASSBOSS real world output specications are provided as “Maximum Sustained Output” ratings, which reect actual measured, continuous output levels.

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:
1. Is the power cord plugged into a live outlet?
2. 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:
1. Is the signal cable connected to the input?
2. Is the signal cable connected to an operating output at the other end?
3. Is the signal owing 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 specications 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
rm surface.
• Ensure that all additional hardware, xings 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.
System Setup Addendum: When connecting multiple loudspeakers in a system, signal can be passed through
from one loudspeaker to another using 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 rst and patch to the next nearest box
in sequence. It is recommended to run the DiaMon 112 as the last box in the sequence when it is mounted on a
pole or tripod stand.

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 elds 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.
