The Bluesound Professional B170S networked streaming stereo amplifier is a complete solution for a commercial music installation. The B170S combines a high-quality stereo low impedance and constant voltage amplifier with a BluOS enabled network music player. The B170S’s amplifier section provides 2 x 80W of power into 4/8Ω or 2 x 100W at 70V or 1 x 100W at 100V. This provides plenty of power for most small/medium spaces and thermostatic fan cooling provides for reliable operation in commercial environments. The amplifier technology is highly energy efficient and also has a standby mode consuming only 6W of power. The addition of constant voltage outputs allows for long chains of small speakers to be powered with variable power tapping at each speaker giving control of local volume.
