DA850

8-channel distribution amplifier

Engineered to work with any JBL architectural loudspeaker to deliver a fantastic high-resolution audio experience throughout the home, the DA850 provide 4 zones of audio in a compact 1U design, providing maximum performance while taking up minimal rack space. Further configurability is supported with bridging of its Class D stereo channels into even more powerful mono outputs when needed. Each zone can have an independent source or share an audio source across all zones using the global audio input. Expand zones sharing an audio source across multiple amplifiers using the global audio output.
