Blustream NPA70DA Amplifier

Deliver consistent, professional audio to commercial AV, security and surveillance installations with the Blustream NPA70DA Amplifier. This Dante networked pro amplifier is engineered for integrators who need reliable zone audio for paging, background music, monitoring rooms and emergency voice systems. It offers flexible power configurations—2x35W per channel in stereo or 1x70W mono—and supports 70/100V constant-voltage output for driving dozens of speakers across long cable runs. Network-first design includes Dante/AES67 audio streams and optional PoE++ to simplify wiring and centralize power, while a local 24V DC supply provides backup power options. The NPA70DA’s integrated DSP and 31-band EQ let you tune each zone for clarity in noisy environments, improving speech intelligibility for security and surveillance paging. Control is straightforward via front panel, IR, RS-232 or IP and a built-in web GUI, making commissioning and monitoring fast for busy integrators. Compact mounting kits allow rack, wall or surface installation for tight spaces. Add the Blustream NPA70DA to your next AV or security project for scalable, networked audio performance—contact us to configure your system.
