Bowers & Wilkins CDA-4D 4 Channel Compact Distribution DSP Amplifier (Black)

DESCRIPTION

The Bowers & Wilkins CDA-4D 4 Channel Compact Distribution DSP Amplifier is a powerful, space-efficient solution designed to drive current and future Bowers & Wilkins Custom Installation speakers with precision and control. Delivering 4 x 125W of high-efficiency Class D amplification in a 1U full-rack-width chassis, the CDA-4D maximizes performance while minimizing rack space. Embedded advanced DSP enables speaker optimization, system tuning, and dynamic EQ for Bowers & Wilkins subwoofers, ensuring consistent, high-quality sound across a wide range of installations. Flexible configuration allows channels to be bridged for 2 x 250W output or a 2.1 setup, making it ideal for multi-room audio, home cinema, or distributed audio systems. With IP control, simple configuration, and compatibility with both existing and future Bowers & Wilkins CI loudspeakers, the CDA-4D is engineered for installers seeking reliability, scalability, and premium audio performance in modern custom installations.

DESCRIPTION

FEATURES

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.
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.
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.
