The CDA-2HD is a high-performance distribution amplifier designed to power current and future Bowers & Wilkins Custom Installation loudspeakers. The integrated DSP enables optimization of a wide range of products and dynamic EQ for Bowers & Wilkins subwoofers. The amplifier features two channels of 500 watts of power each, and its 2U, half-rack-width design ensures high performance in minimal rack space.
