I am wiring up my new layout and I’ve run into a problem with my ZW-C. It’s powered by 4 of the 180-Watt PowerHouses. All the measurements below have been taken in conventional mode; I have not wired up my Legacy command base yet and I’m not sure whether or not operating in command mode would change the results.
When the handles are in the off position, the voltage at each channel’s post on the ZW, according to my multimeter, is as follows:
A – 0.2 V
B – 0.2 V
C – 0.2 V
D – 18.3 V
When I position the handles at full throttle, I get:
A – 13.1 V
B – 17.5 V
C – 17.3 V
D – 18.6 V
What specifically concerns me are channels A and D: A does not exceed 13 V output and D seems to be outputting the same voltage whether or not it’s on or off. I performed the recalibration procedure twice and the numbers did not change.
As a sanity check, each PowerHouse is outputting about 18.5 V (as tested at the Molex connectors) and all are in phase.
Does anyone have any thoughts or ideas that could shed some light on this?
