The Clair Brothers 1AM is the next generation single12” stage monitor / multipurpose loudspeaker. Theengineering behind the 1AM combines the Clairtradition of great stage monitors with the successfulClair coaxial horn technology developed over thepast 5 years. The result is a highly capable andcompact speaker with excellent coherence betweencomponents that is simultaneously in-your-face andsmooth and hi-fi sounding. The 1AM is not only astage monitor, but also very capable of portable andinstalled PA functions based on its integral mountingpoints and pole mount. A family of optional mountingaccessories is available to facilitate permanentinstallation configurations.

1AM Transducer Components:
The highfrequency compression driver features a 1.5” throatdiameter (3” voice coil diameter), a pure titaniumdiaphragm, and a neodymium magnet assembly.The driver is joined to a 40° horizontal by 60° verticalrotatable horn. A 12” cone transducer providesmidbassand low frequency reproduction.

1AM Connectors:
Dual rear mounted connectorsallow the use of multiple cabinets from a singleamplifier. Additionally, there are three slightly morehidden connectors. Two are positioned within the leftand right side handles, and the other is on the bottom.When used for drum fills or in pole-mount positionsthese additional connectors prove to be extremelyuseful for clean cable management.

1AM+ Electronics:
The 1AM is also available as a ‘self-powered’ versioncalled the 1AM+. The 1AM+ features an extremelylightweight and powerful OEM amplifier modulemade exclusively for Clair Brothers by Powersoft.The base configuration of the 1AM+ features asimilar DSP to the successful kiTSeries with 32-bitfloating point processing with crossover slopes upto 48dB/oct and FIR filtering. The 1AM+ input panelfeatures PowerCon (In/thru) connectors and a pair ofXLRs (In/thru). The 1AM is voltage agile with a PFCcorrected 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
