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.
