Plus One for Clair Brothers One+ Series

Unveiled earlier this year at Prolight + Sound 2017, Clair Brothers proudly introduces a bold new addition to its highly successful line of One Series 12- and 15-inch coaxial stage monitors: a self-powered version of the 1.5AM monitor called the 1.5AM+. On the heels of last year’s introduction of the powered monitor 1AM+, the amplified sister of the 1AM monitor, Clair Brothers continues to propel the pro audio industry forward.

Clair Bros One+ Series

The expanding One Series product line continues the tradition of stage monitoring excellence begun by the acclaimed Clair 12AM. The 1.5AM+’s internal, factory-programmed DSP loudspeaker processing gives users Xover, EQ, Limiter, and a total of four preset options. Of interest to current 12AM owners, the 1.5AM+ features factory-programmed processing that delivers two ‘12AM Emulation Mode’ preset options (32dB gain or 38dB gain); these presets provide similar frequency response voicing and low-frequency phase response for seamless compatibility for 1.5AM+ to be deployed harmoniously with existing fleets of 12AM monitors. The two remaining presets are options designed for low-frequency optimization on stage as the 1.5AM+ may be coupled with other two-way monitors or with stage subwoofers. The “Mon A” preset offers a two-way phase vs. frequency characteristic and the “Mon B” preset includes an all-pass filter that aligns the low-frequency phase response seamlessly with subwoofers across the lowest octaves. It’s recommended to combine these monitors with Clair CS or kiT-Series subwoofers.

Like the 1AM+, the 1.5AM+ contains a lightweight, powerful amplifier module made exclusively for Clair by Powersoft; this module allows users to power a passive (non-powered) 1.5AM with a slave output. “Simply connect the 1.5AM+ by cable to a non-powered 1.5AM and power the pair. While this is a mono (not stereo mix) configuration, this is a very unique, value-added feature,” says Josh Sadd, vice president and chief engineer at Clair Brothers. The integrated amp notably delivers two-channel (1600W each) 3200W total power.

The 1.5AM+ offers a coaxial design and a proprietary high-frequency rotatable horn (40°H x 60°V standard dispersion) carved from premium Baltic birch. This proprietary horn design includes sculpted wooden acoustic filters that optimize the magnitude and phase response between the coaxial components in the crossover region – effectively avoiding the shadowing of the woofer with the horn, as well as the early reflection from the rear of the horn. The end result is a remarkably coherent, exceptional sound quality that gives the effect of a full PA system for the performer. Low-profile, sleek-styling and ergonomic, flush-mounted side handles afford great aesthetic appeal and portability. The 1.5AM+ monitors are travel-ready with a rugged exterior finish, a resilient grille design, and road cases designed to carry pairs. Custom cabling for systems is available and can be pre-wired, labeled and delivered in road cases.

Clair Brothers vision of the 1.5AM+ is that it is well suited for vocal monitoring and on-stage instrument reinforcement (drum fill, bass and keyboard monitors), but especially for DJ / EDM monitors. Those looking for the Rolls Royce of stage monitors should certainly consider Clair Brothers 1.5AM+.
