Bluesound Professional A860 8 Channel Amplifier

About The Bluesound Professional A860 8 Channel Amplifier

The Bluesound Professional A860 is a high quality 8-channel power amplifier for use in commercial installations. This 2U amplifier provides 50W x 8 at 8Ω, 60W x 8 at 4Ω or 120W at 8Ω per pair of channels in bridged mode. A standby mode can be triggered remotely or automatically for low power consumption when not in use. A global input can be assigned to multiple outputs and global and local output facilitate multiple amplifier installations. Thermostatically controlled fans ensure trouble-free operation in a wide range of conditions.

Bluesound Professional Streaming Integration

Easily Create Branded Environments: With hardware that supports nearly unlimited zones of audio and a natively-integrated commercially-licensed music streaming service in SoundMachine, Custom Channels, Qsic and Tunify, Bluesound Professional makes easy work of creating branded environments for your installation.

Seamless Integration with Control Systems: Bluesound Professional’s line of commercial streaming hardware allows flexible control by third-party control systems, and interfaces exist for all of today’s market-leading automation platforms. BluOS®, the multi-zone, music sharing software that underpins all Bluesound Professional players and active speakers, communicates with third-party control systems and platforms so that A/V system integrators, business owners, consultants and system designers can design seamless audio ecosystems to meet the needs of any commercial installation.

Standard rack sizes and a wide range of standard inputs and outputs means that installation is quick and simple. The ecosystem’s modular design allows it to work seamlessly as an audio system on its own, or with audio components from other brands.

Add Audio Streaming to Existing or New Installations: Bluesound Professional’s decentralized processing capabilities gives designers and installers maximum flexibility to add audio streaming to installations, whether existing or new.

Easy to Configure: Self-discovery makes set-up and configuration painless, as Bluesound Professional players placed onto the same network will find each other automatically. A few taps on the intuitive icons in the BluOS Controller app will group players to create zoned audio content and lock-out unauthorized users.
