A860

8-Channel Power 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.

  • 8 channels of high-quality amplification
  • Balanced line inputs for commercial use
  • Automatic or remotely triggered standby mode for 0.5W low power consumption
  • Thermostatically controlled low noise fans ensure reliable operation
  • Global balanced input routable to multiple outputs
  • Pass-through global and local balanced line level outputs for multi-amplifier installations
  • Compact 2U rack-mount form factor
  • Indicators for amplifier and channel status
