The Clair Brothers 1AM+ is the next generationsingle 12” stage monitor / multipurpose loudspeaker.The engineering behind the 1AM+ combines theClair tradition of great stage monitors with thesuccessful Clair coaxial horn technology developedover the past 5 years. The result is a highly capableand compact speaker with excellent coherencebetween components that is simultaneously in-yourfaceand smooth and hi-fi sounding. The 1AM+is not only a stage monitor, but also very capableof portable and installed PA functions based on itsintegral mounting points and pole mount. A familyof optional mounting accessories is available tofacilitate permanent installation configurations.

1AM+ Transducer Components:
The high frequency compression driver featuresa 1.5” throat diameter (3” voice coil diameter), apure titanium diaphragm, and a neodymium magnetassembly. The driver is joined to a 40° horizontal by60° vertical rotatable horn. A 12” cone transducerprovidesmid-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 connectorsthat can output loudspeaker signal level to powera non-powered 1AM. One is positioned within theright side handle and the other on the bottom. Whenused for drum fills or in pole-mount positions theseadditional connectors prove to be extremely usefulfor clean cable management.

1AM+ Electronics:
The 1AM+ features an extremely lightweight andpowerful OEM amplifier module made exclusivelyfor Clair Brothers by Powersoft. The baseconfiguration of the 1AM+ features a similar DSPto the successful kiTSeries with 32-bit floating pointprocessing with crossover slopes up to 48dB/oct andFIR filtering. 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
native to the 1AM+ built-in DSP. The preset modes
(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

Architect and Engineer Specifications
The loudspeaker shall be a two-way active system featuring a total of two drivers. The low frequency module contains one 12 in. drivercapable of handling 350 watts of pink noise with a 6 dB crest factor for 8 hours (as per EIA RS-426-A standard). The high frequency modelcontains a 1.5 in. exit, 3 in. voice coil diameter compression driver joined to a 40° horizontal by 60° vertical rotatable horn. The 3 in. driver iscapable of handling 80 watts (1 kHz to 10 kHz) of pink noise with a 6 dB crest factor for two hours (as per AES-1984 and ANSI S4.26-1984standards). The signal processing is Clair Brothers proprietary data. The enclosure shall be constructed of premium grade Baltic birch andcovered with a durable black polyurea finish. The dimensions shall be 14.82 in high, 20.32 in wide, and 22.0 in deep. The system weight shallbe 61 lbs (27.7kg). The loudspeaker shall be the Clair Brothers 1AM+.
