1: Output Power:   Nominal output power levels are limited by the amount of current the D130/D250 is allowed to 

draw form a residential branch circuit.  Power output from individual channels or from groups of 
channels can be much higher when only some channels are driven to high power levels. Note 
that each of the two zones, of 4 channels each, has its own power supply.  Therefore, if two or 
more channels are going to be driven harder than the others, it is wise to try to balance the power 
demand across the two zones and thus the two power supplies. 

2: D65: 

 Although the nominal output power per channel of the D65 is 65 Watts per channel with all chan-
nels driven, actual power output can reach 90 Watts  even when all 8 channels are driven.

3: D130: 

 Although the nominal output power per channel of the D130 is 100 Watts per channel with all 
channels driven, actual power output can exceed 140 Watts per channel when only 6 channels are 
driven.

4: D250: 

 Although the nominal output power per channel of the D250 is 110 Watts per channel with all 
channels driven, actual power output can exceed 150 Watts when 6 channels are driven, 230 
Watts per channel when only 4 channels are driven or 290 Watts per channel when 3 channels are 
driven.

5: Standby: 

Unit is plugged in but power switch is deactivated.
