The CDA-4D is a compact distribution amplifier, designed to power current and future Bowers & Wilkins Custom Installation loudspeakers. Embedded DSP allows optimisation of a wide range of products and dynamic EQ for Bowers & Wilkins subwoofers. It boasts four channels of 125 watts each, and its full-rack-width 1U design delivers high-performance from minimum rack space.
