Can the amplifier be used with products from the Professional Systems Division at Bose, such as the MB4, MB24 or 802®?
The A1 is designed for 4-ohm loudspeaker loads capable of 250W RMS. The MB4, MB24 and 802® are rated at an impedance of 8-ohms nominal. Coupled with higher power requirements at their load rating, the A1 is slightly underpowered for use with those loudspeakers. We recommend the Bose® 1600 or Bose 1800 amplifier together with the Panaray® controller to properly drive those loudspeakers. For more information, please visit http://www.pro.Bose.com.
