Networked zone amplifier with Dante, 2 x 50 W or constant-voltage line
The Blustream NPA100DA is a single-zone network audio amplifier with Dante inputs and outputs, built for residential and professional AV installations.
Its digital power stage runs in stereo at 2 x 50 W, in mono at 100 W into 4 or 8 ohms, or on a 70 / 100 V constant-voltage line to drive many speakers over long cable runs. Besides the speakers it feeds a dedicated subwoofer output and a stereo analogue output. Sources can come from the Dante network, from the TV's HDMI ARC, from a microphone, from an optical input or from an analogue input. Power comes from the switch via PoE++ or from the bundled 36 V adapter; on PoE the output power can be lowered to match what the switch can deliver. The Dante and LAN ports can stay separate or be merged onto a single cable.

Connections
Inputs on Phoenix terminals (5-pole analogue, 3-pole mic), a locking HDMI for ARC and an S/PDIF optical. The outputs use a 4-pole Phoenix for 4 / 8 ohm speakers, 3-pole for the 70 / 100 V line, 5-pole for analogue and 2-pole for the subwoofer. There are two RJ45 ports (Dante and network), plus RS-232, IR and trigger on Phoenix. The unit measures 250 x 150 x 45 mm and comes with a 36 V / 5.5 A adapter, remote, IR receiver, rack and wall kits, rubber feet and a quick guide.
