Jbl da850 Da professional 8 channel amplifier grey

DA850 8 channels

Designed to work best with any JBL Architectural Series speaker, it offers a fantastic audio experience throughout the home. JBL DA850 can sound 4 independent zones in stereo, and takes up minimal space if positioned in a rack (only 1 1U module). The possibility of setting its outputs to bridge in mono, makes it perfect even in systems where more power is needed. The amplification stages are in class D, therefore highly efficient with limited heat dissipation. Each zone can have an independent source or share the same audio signal in all zones via the common “global audio” input. It is also possible to expand the zones, sharing an audio source between multiple amplifiers, thanks to the “global audio” output.

KEY FEATURES

Compact, it takes up the space of a single rack module, and is stackable

Possibility to bridge the outputs, for greater power requirements

Protection against both short circuits and overheating, prevents potential damage to both itself and the speakers

3 power modes (Power Mode), 12V trigger, signal-presence power-on and always on

Local or Bus input, stereo/mono selector and output level control for each channel
