STM M28 Omni-purpose Module STM M46 Main Module

The building blocks

for every system you’ll ever need.

STM B112 Bass Module

STM S118 Sub Module

For too long now, the business of a sound rental company has been
dictated by system manufacturers. You need one type of system to
be in the touring market, another for corporate jobs, and so on. It
all adds up to a lot of boxes that often spend more time in the
warehouse than they do on the road.

STM changes all that. The concept of Scale Through Modularity
delivers a new level of versatility, enabling contractors to design a
wide range of systems from just four compact, powerful and
proportionally-sized modules. And in applications large and small,
these systems can significantly outperform existing solutions.

Of course increased versatility brings a welcome improvement in
return on investment. But with STM, that’s just the start. From system
storage and configuration, through transportation and rigging, to
wiring and amplification, STM delivers important operational and
logistical cost savings at every stage of the process.

A simple groundstack is perfect for small applications.

A single column of M28 Omni modules creates a

powerful, compact and lightweight system, perfect

for speech and small venue music applications.

In large format applications, a double column of M46
Main and B112 Bass modules flown on a lightweight

bumper is smaller and more powerful than competitive

line arrays.

From a simple groundstack

to a compact, powerful array.

From a simple groundstack to a compact, powerful line array, STM makes it quick and easy to ‘clip together’ the systems you need
for any job.

Configuration possibilities include M28 Omni or M46 Main cabinets only, Omni/Main + Bass, Omni/Main + Sub, Omni/Main + Bass + Sub,
any of which can be supplemented by the M28 Omni module operating as a downfill. The wide operating frequency range of the M28 Omni
cabinets means that many speech or light music events can be run effectively with M28 alone, thereby removing the need for any extra
cabinets. If programme material calls for low frequency extension, the 25-120Hz range of the S118 sub and the 55-200Hz range of the
B112 bass offer the user complete freedom when configuring the system to achieve the desired frequency response or power.

The perfect system

for every event.

STM is all about flexibility, so there’s no such thing as a ‘typical system’. Operators use NS-1
configuration software (see page 15) to design the perfect system for the application at hand.
STM’s modular approach means there’s no longer a requirement to own separate small, medium
and large systems as applications of any size and scale can now be handled from a common
inventory of STM modules.

Sharing the same footprint as the other STM modules, and precisely twice the height of the Main and
Bass cabinets, the STM S118 Sub-Bass module also shares the same rigging system, allowing it to
be groundstacked or flown above, below or between other STM modules. Using a single 18" driver in
an innovative cabinet design, the S118 delivers performance levels comparable to NEXO’s acclaimed
CD18 2 x 18" sub, empowering the STM system with a compact, potent and highly musical sub-bass
solution. The STM Sub can be used in omni or cardioid modes depending on cabinet positioning and
preset selection.

Double column with downfills

The lightweight bumper includes adjustment to enable
a straight hang where M28 Omni modules are used as

downfills on one column only.

Pushing the envelope.

Problem-solving possibilities beyond the norm.

True modularity makes it possible to configure an STM system for every application – systems that are often more compact than
conventional line arrays.

But STM isn’t just about convenience, efficiency and return on investment. It’s also about performance. The facility to configure large scale
systems from four compatible modules can deliver a dream system for rock and metal bands, with unprecedented low frequency headroom.

STM Large-Format System

Configured using NS-1 system simulation tool.

STM modularity offers unique solutions to common audio problems. For example, in arena, stadium or large festival applications, the
well-known issue of low-frequency interference between main and side hangs can be addressed by centralising the B112 Bass
cabinets in separate hangs between forward and outward facing M46 Main cabinet arrays, thereby ensuring the bass frequencies
emanate from a single source.

The concept of true modularity is equally welcome in small venues, where STM’s Omni/Main cabinets can be flown alone and Bass and/or
Sub cabinets can be groundstacked to overcome the limitations of low weight-bearing facilities (for example, 500kg points).
