BRS-12A3 is an ultra-compact 3 channel self-powered subwoofer. Utilising a custom designed and UK made Ohm 12” long excursion driver, this reflex tuned cabinet has an exceptionally low frequency response of as low as 33 Hz and a max SPL of 129 dB.
The BRS-12A3 houses 2 x 1 kW Class D amplifiers and outputs through 3 DSP channels which can be locally adjusted via the LCD or remotely configured via a USB socket on any Windows PC or Mac computer running our Pro-A-Sync software.
Output one is split between the internal driver and a shared bass output for connecting a passive BRS-12 subwoofer. Outputs 2 & 3 deliver 500W RMS (4Ω) per output for passive satellite speakers. Look-ahead and RMS limiters combined with intelligent DSP features like active gain reduction, give total system protection even under the harshest conditions.
Designed with installation or portability in mind, a low-profile design height of 333mm allows installation under industry standard fixed seating. Integrated handles and a modest weight of 25 Kg make transport easy. A pole mounting plate gives another option for temporary setups. Wall or ceiling mounting using the optional BRSC-12 bracket makes this small subwoofer easy to install in even the smallest venue.
Solving compact portable audio by using 2 x BRW-26 1x BRS-12A3, 1 x BRS-12 and pole mounts that all fit in the back of a standard car. The system is light enough to carry, the whole system to be conveniently stacked and transported on the optional wheel board.
