Each channel of the DA850 and DA1650 delivers 50W into 8ohm loads and 110W into 4ohm loads. When bridged, the output increases to 185W into 8ohm loads.
The amplifiers also offer flexible audio routing: each zone can have its own independent audio source, or a single source can be shared across all zones via the global audio input. Zones sharing a common source can be expanded across multiple amplifiers using the global audio output.
