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-your-face 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 midbass and low frequency reproduction.
1AM Connectors: Dual rear mounted connectors
allow the use of multiple cabinets from a single
amplifier. Additionally, there are three slightly more
hidden connectors. Two are positioned within the left
and right side handles, and the other is 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 is also available as a ‘self-powered’ version
called the 1AM+. 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+ input panel
features PowerCon (In/thru) connectors and a pair of
XLRs (In/thru). 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
for both Lake processing and 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.
