All items are measured across 8 

Ω

 load at speaker output terminal with L.P.F. 

Note:

Nominal specifications represent the design specifications. All units should be able to approximate these. 
Some will exceed and some may drop slightly below these specifications. Limit specifications represent 
the absolute worst condition that still might be considered acceptable. In no case should a unit fail to meet 
limit specifications.
