    Comments about Crown Audio 280A 2 Channel, 2 x 80W Amplifier:

    We bought the Crown 280A amplifier for our small shopping center. We use it as a 70 volt system and need the 2 channel outputs to differentiate the volume level between outdoors and indoors. We could fine tune the volume by tapping the speakers differently but it is much easier to do it with a 2 channel amp. We bought the 280A to replace a 280MA that had played continuously for 6 years but had recently blew a channel. As we only require one input channel we felt the 280MA was overkill. Unfortunately, the 280A does not come with a phono plug input, only the 3 point phoenix style plug. It went from a simple replacement project to hiring a sound expert to redesign our setup. My only other frustration is with the volume controls which, like the 280MA, have definite stops around the radius which makes it difficult to fine tune the volume. The 280MA had an input volume also which helped the fine tuning but the 280A does not. Love the quality of Crown though.

    We were pleased with this amp in our new building. It worked great and the dual amps worked perfectly for what we needed.
