Mighty Flexible the CDA-16

Offering 16 channels of power, the CDA-16 can enable your whole home with sound yet takes up minimal space thanks to its compact 1U design. Its configurable specification supports bridging of its Class D stereo channels into even more powerful mono outputs, if needed.

CDA-16 has been engineered to work with any existing Bowers & Wilkins custom installation speaker. With the ability to drive 16 channels or 8 zones in a compact 1U design, CDA-16 gives you the maximum performance with the minimum rack space.

Ensure the best possible sound from your in-wall or in-ceiling Custom Installation loudspeakers with our powerful yet compact distribution amplifier.
