It is compulsory to read this user manual before operating M15’s . Supervision and competency
are the responsibility of the system owners and operators. Owners and operators are responsible
for inspecting the rigging and ensuring that it has not been damaged in transport, from misuse, or
wear and tear. M15 loudspeakers are easily capable of generating high sound pressure levels that can
cause permanent hearing damage and should be operated by personnel with experince in professional
audio.

This manual is intended to demonstrate and help M15 owners with the operation of the M15 and its optional MASS™
(Multi Angle Suspension System) rigging system.

The Essential Multi-Purpose Box
The M15 is a multi-purpose high output enclosure, that can be used as a stage monitor, FOH system, center enclosure,
or as a fill device.
The M15’s symmetrical cabinet design facilitates mirror imaging when used as a stage monitor by maintaining the
same projection angle. The indescreet simplified Adamson logo indicates the low LF driver end. When placed side to
side with the logos facing the low frequencies will couple. When placed on the opposite side, the horns will couple
The M15 employs a switch which allows bi-amped or passive operation. It uses internal crossover circuitry when in
passive mode, which is automatically by-passed when in active mode.
The cabinet is loaded with a single ND-15L, a 15 inch LF driver which incorporates a lightweight long excursion
neodymium magnet, enhancing output, delivering superior powerhandling and providing consistently stable low end
frequency response.The ND-15’s basket utilizes an enlarged heat sync and thermal fins which draw heat away from the
coil, lowering its operating temperature and improving thermal compression.
Constructed from Baltic birch, it is designed to
accept a multi-purpose rigging plate that allows
several different methods of flying the cabinet
(see Rigging section).
The ND-15 is the only driver with zero-axial
modes in it’s entire passband. (60-800 hz) This
substantially increases the linearized mid-band
response.
Compared to traditional paper cones, the
multilayer Kevlar cone along with advanced cone
architecture, offers superior performance, zero fatigue and eliminates cone modes in the passband.
The internally bracd birch cabinet is sealed at
all joint abutments are is finished in a weather
resistent powdercoat, and the screen is
laced with replaceable, acoustically
transperent
open cell grill cloth. The cabinet is loaded with
a 50 degree conical fiberglass acoustic

Active/Passive Operation
In full range mode with presets the frequency response of the M15 is 60hz-18khz with a +-3db variation factor.
The crossover point between low and high frequency components is 800hz. . Always use presets when operating the M-
15, whether in active or passive mode.
Adamson recommends powering the M15 with a Lab.gruppen fP3400 stereo amplifier producing 1100w per channel
@8ohms, and providing AC, VHF, thermal, DC and clip limiting protection.
In passive mode, up to two cabinets can be linked on one channel. In passive mode all signals are routed to one
channel of the fP3400.
To select active mode, switch the protected toggles on the rear of the cabinet.
With the bi-amped setting, you enable up to two cabinets to be powered by two channels of a single fP3400. In a 2-
way active configuration the LF and HF signals are routed sepearately to the amplifier channels.
It can also be paralleled to other M15’s through four NL-4 Speakon connectors. Using one of the four connectors for the
speaker input allows a second connector to function as a feed to jump additional cabinets.
1. Remove the backplate to access the dipswitches. Choose active or passive mode and replace the cover with the
indicator facing the appropriate direction.
1. exposed dipswitches-Ensure
that both switches are set to either
active or passive mode at any
one time.
In passive mode , Pins 1+/1- of all four
NL4 connectors feeds the full range signal
to the High and Low frequency drivers,
through their own passive crossover units.
In active mode the Lap.gruppen
fP3400powers up to two cabinets. Pins
1+/1- of the four connectors carry the
LF signal and pins 2+/2- of the four
connectors carry the HF signal. The pin
configuration is automatically changed
when Bi-amped active mode is selected.

Adamson’s X-Link software controls the M-Series Digital
Processor.
Processing and presets
Adamson recommends processing signals with the Adamson M Series digital processor, but factory presets are
available for approved digital signal processors, and are available through either the official Adamson website (link be-
low) or by request.
www.adamsonproaudio.com technical_support/presets/index.htm
M-series Processor Presets are determined through polar measurements and spacial averages to optimize equalization,
crossover points and time alignment.
M15 Preset librairies for XTA’s processors can be obtained from the Adamson website, by request from your local
Adamson distributor or the Adamson Head office, and are applied using audio-core software.
Below is a reference chart of XTA DP224 V.11 presets.
For up to date presets check the above website link.

Rigging with the MASS™ System
The M15 optional accessories include the
MASS™ (Multi Angle Suspension System)
which features several different methods of
flying the cabinet.
The M15 is designed to accept a multi-
purpose rigging plate, which is the base for
the following rigging methods covered in
the manual.
MASS™ is designed for a
single or a pair of M15’s.
MASS™ is perfect for installation
or touring applications and is
available upon request.

Rigging with the MASS™ System
When mounting the M15 with MASS™, ensure the boxes are securely fastened and mounted properly. Suspended
speakers should always be reinforced with steel safety cable and inspected by an experienced crew member.
When pole mounted, verify the stand is placed on a level surface, the tripod legs are fully extended and do not
present a trip hazard. in adverse outdoor conditions it may be necessary to support the base of the stand with
additional weight.
It is good practice to regularly inspect any cabinets housings for signs of wear, and load bearing bolts in mounting
devices. MASS™ is intended for use with the M15 only.
