Bowers & Wilkins CDA-2HD DSP Amplifier, 2 Channel


A high-power distribution amplifier, with two channels of 500 watts each, DSP for product optimisation and dynamic EQ for subwoofers.


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 channels of 500 watts each, 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 500 watts of Class D amplification on board it can bring the power when required. Plus, as it’s bridgeable this can be configured to deliver 1,000 watts where needed.


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.
