Stock Code: CDA4D

Bowers & Wilkins CDA-4D DSP Amplifier, 4 Channel 125 watts, Black

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.

Impressively smart

To ensure the CDA-4D 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 for providing dynamic EQ for Bowers & Wilkins subwoofers.

Compact powerhouse

CDA-4D’s 1U size means that it takes up the minimum of rack real estate. But with four channels of 125 watts of Class D amplification on hand it can deliver power when required. Plus, as it’s bridgeable this can be configured to 2 x 250 watts, or a 2.1 setup (2 x 125 watts and 1 x 250 watts), where needed.

Flexible

Whether you are looking to upgrade an in-situ installation or planning a new one, the CDA-4D DSP amplifier is ideal. It can drive two zones, and works with a wide variety of Bowers & Wilkins products, both current and future
