The CDA-2HD is a high-power distribution amplifier, designed to drive 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 two powerful channels, and its half-rack width 2U design delivers high-performance from minimum rack space.
Impressively smart
To ensure the CDA-2HD delivers in the modern custom installation system, it is equipped with Digital Signal Processing (DSP). This allows it to be used in wide variety of situations, provides control over IP and configuration, and dynamic EQ for Bowers & Wilkins subwoofers.
Compact powerhouse
CDA-2HD's half-rack width 2U size means that it takes up the minimum of rack real estate. But with two channels of Class D amplification on board it can bring the power when required. Plus, as it's bridgeable, this can be configured to deliver even more power where needed.
Flexible
Whether you are looking to upgrade an in-situ installation or planning a new one, the CDA-2HD DSP amplifier is a great solution. It combines power with finesse, and works with a wide variety of Bowers & Wilkins products, both current and future
