The Clair Brothers 1.5AM+ is the next generationsingle 15” coaxial stage monitor with incrediblelow frequency output. The engineering behind the1.5AM+ combines the Clair tradition of great stagemonitors with the successful Clair coaxial horntechnology developed over the past 5 years. Theresult is a highly capable and compact speaker withexcellent coherence between components that issimultaneously in-your-face and smooth and hi-fisounding.

1.5AM+ Transducer Components:
The high frequency compression driver features a2” throat diameter (4” voice coil diameter), a puretitanium diaphragm with a titanium nitride coating,and a neodymium magnet assembly. The driver isjoined to a 40° horizontal by 60° vertical rotatablehorn. A 15” carbon fiber reinforced cone transducerprovidesmid-bass and low frequency reproduction.

1.5AM+ Connectors:
The 1.5AM+ input panel features PowerCon (In/Thru) connectors and a pair of XLRs (In/Thru).

1.5AM+ Electronics:
The 1.5AM+ features an extremely lightweightand powerful OEM amplifier module madeexclusively for Clair Brothers by Powersoft. The baseconfiguration of the 1.5AM+ features a similarDSP to the successful kiTSeries with 32-bit floatingpoint processing with crossover slopes up to 48dB/oct and FIR filtering. The 1.5AM+ is voltage agilewith a PFC corrected PSU that accepts 85-240VAC50/60Hz.

1.5AM/1.5AM+ Preset Modes:
The 1.5AM presents interesting preset
configurations native to the 1.5AM+ built-in DSP.
The four preset modes include:
(1) 1.5AM Monitor Mode A
(2) 1.5AM Monitor Mode B
(3) 1.5AM 12AM Emulation Mode 32 dB
(4) 1.5AM 12AM Emulation Mode 38 dB

Other Features:
Low profile styling and ergonomic, flush mountedside handles provide great aesthetic appeal andportability. The speaker grille is constructed ofaerospace grade perforated aluminum and isspecially treated to create a durable exterior finish.

Architect and Engineer Specifications
The loudspeaker shall be a two-way active system featuring a total of two drivers. The low frequency device is one 15 in. driver capable ofhandling 800 watts of pink noise with a 6 dB crest factor for 8 hours (as per EIA RS-426-A standard). The high frequency device is a 2 in. exit,4 in. voice coil diameter compression driver joined to a 40° horizontal by 60° vertical rotatable horn. The 4 in. driver is capable of handling 130watts (1 kHz to 10 kHz) of pink noise with a 6 dB crest factor for two hours (as per AES-1984 and ANSI S4.26-1984 standards). The signalprocessing is Clair Brothers proprietary data. The enclosure shall be constructed of premium grade Baltic birch and covered with a durableblack polyurea finish. The dimensions shall be 13.79 in. high, 25.0 in. wide, and 23.11 in. deep. The system weight shall be 78 lbs (35.4kg).The loudspeaker shall be the Clair Brothers 1.5AM+.
