The Meyer Sound B-2A is a dedicated, high-resolution control electronics unit specifically designed as the system processor for the Meyer Sound B-2 UltraSeries Ventilated Ribbon Subwoofer. This processor forms an integral, non-interchangeable component of the complete B-2 loudspeaker system, embodying Meyer's philosophy of optimized, speaker-specific electronic control. Its primary function is to provide the precise digital signal processing required to manage the unique dual-ribbon transducer technology of the B-2 subwoofer, which operates fundamentally differently from conventional moving-coil subwoofers. The B-2A delivers the necessary crossover filtering, driver equalization, phase correction, and multi-stage protection limiting that allows the B-2 to achieve its exceptional performance in terms of extremely low distortion, high output, and extended low-frequency response down to 30 Hz.

The processor is engineered to extract maximum performance and ensure the longevity of the sophisticated B-2 transducer. It applies corrective equalization to flatten the system's inherent response and integrates high-pass and low-pass filtering tailored for the B-2's operating bandwidth. A critical role of the B-2A is its comprehensive protection circuitry, which actively monitors the amplifier output and transducer parameters to prevent damage from over-excursion or thermal overload, which is vital given the precision and cost of the ribbon driver. The unit typically features balanced XLR inputs and outputs, level controls, and status indicators, providing a straightforward interface for system integration. It is designed to be used with specified Meyer Sound or other high-quality external amplifiers that meet its required voltage and current specifications.

Housed in a rugged 1U rackmount chassis, the B-2A Processor is built for reliability in both fixed installations and touring environments. It represents a mandatory link in the signal chain for the B-2 subwoofer; operating the subwoofer without this matched processor would not only fail to realize its designed acoustic potential but could also risk damaging the transducer. By packaging this advanced, application-specific processing in a standalone unit, Meyer Sound guarantees that every B-2 subwoofer system performs with consistent, predictable, and reference-grade low-frequency reproduction, whether used individually for extended-range full-range systems or in arrays for large-scale concert reinforcement. The B-2A is the essential electronic key that unlocks the full power and fidelity of this innovative subwoofer technology.
