In this manual you will find important information regarding the use of your MA-2.2B and 

we suggest that you do read it before using the unit. 

 

If after unpacking the MA-2.2B you find any damage you should contact your dealer or 

supplier immediately for advice on what to do. 

 

We also suggest you retain the original packaging at least during the warranty period in

Warm Up. 

The Buzz Audio MA-2.2B utilises discrete Class A amplifiers which take about 30 mins to 

warm up.  We suggest you keep the MA-2.2B switched on whilst in regular use to ensure 

continuous sonic performance.
