Amplifiers / Pre-Amps
For high-end and professional installations, the Bowers & Wilkins CDA-4HD 4-Channel 125W DSP Amplifier can provide 125W of power distribution across four channels at 4 ohms, or if needed, bridged to deliver 2 or 2.1-channels of sound. Either two 250W or two 125W with one 250W. Made to power custom Bowers & Wilkins loudspeaker installations, the integrated Digital Signal Processing (DSP) lends the CDA-4HD the ability to be used in a variety of setups, and also features a dynamic EQ for tuning Bowers & Wilkins subwoofers. Plugging into your rack with a 1U design and full-rack width, the CDA-4HD takes up minimal space, and offers an Ethernet connection for convenient amplifier management over a local network.
