The Clair Brothers 1AM+ is the next generation
single 12” stage monitor / multipurpose loudspeaker.
The engineering behind the 1AM+ combines the
Clair tradition of great stage monitors with the
successful Clair coaxial horn technology developed
over the past 5 years. The result is a highly capable
and compact speaker with excellent coherence
between components that is simultaneously in-yourface and smooth and hi-fi sounding. The 1AM+
is not only a stage monitor, but also very capable
of portable and installed PA functions based on its
integral mounting points and pole mount. A family
of optional mounting accessories is available to
facilitate permanent installation configurations.
1AM+ Transducer Components:
The high frequency compression driver features
a 1.5” throat diameter (3” voice coil diameter), a
pure titanium diaphragm, and a neodymium magnet
assembly. The driver is joined to a 40° horizontal by
60° vertical rotatable horn. A 12” cone transducer
provides mid-bass and low frequency reproduction.
1AM+ Connectors:
The 1AM+ input panel features PowerCon (In/Thru)
connectors and a pair of XLRs (In/Thru). Additionally,
there are two slightly more hidden connectors
that can output loudspeaker signal level to power
a non-powered 1AM. One is positioned within the
right side handle and the other on the bottom. When

used for drum fills or in pole-mount positions these
additional connectors prove to be extremely useful
for clean cable management.
1AM+ Electronics:
The 1AM+ features an extremely lightweight and
powerful OEM amplifier module made exclusively
for Clair Brothers by Powersoft. The base
configuration of the 1AM+ features a similar DSP
to the successful kiTSeries with 32-bit floating point
processing with crossover slopes up to 48dB/oct and
FIR filtering. The 1AM+ is voltage agile with a PFC
corrected PSU that accepts 85-240VAC 50/60Hz.
1AM/1AM+ Preset Modes:
The 1AM presents interesting preset configurations
native to the 1AM+ built-in DSP. The preset modes
include:
(1) 1AM Stage Monitor Mode
(2) 12AM Emulation Mode
(3) 1AM Full Range PA Mode
(4) 1AM 100Hz HPF Mode (for use with
complementary subwoofer)
Low profile styling and ergonomic side handles
along with an extended front handle provides great
aesthetic appeal and portability. The speaker grille is
constructed of high grade 14 gauge perforated steel
and is specially treated to create a durable exterior
finish.
