Samuel aka Grant: Thanks for taking the time to respond and provide more info. I was beginning to wonder if this was going to be like the last thread where i asked questions of a manufacturer and they never responded. They did respond to others within that thread both before and after those questions / comments, but they somehow seemed to overlook what i threw their way. Wonder how that happened ??? : )
As to my previous comments, i based them on the info and pictures available on your website. As such, you might want to update your website and check the wording used. While you state that the Hydra 8 is parallel wired rather than daisy-chained, where would the use of copper buss bars come into play then? The info on your website makes a big deal of how heavy the buss bars are that are used in the Hydra 8 and even shows them, but doesn't actually show the internal construction of the unit. As such, one is lead to believe that these units are all based on the same basic design / operating parameters with the only variables being the amount of outlets available. Evidently, such is not the case. This is confusing to say the least.
"The measured Voltage drop across a 2" 9 gauge silver plated buss strap is so small that it is irrelevant to operation and could not possibly create a voltage sag that would harm or otherwise alter the performance of electronics that are connected. There will always be a common point at which current converges no matter the wiring or buss arrangement"
I never said that voltage sag would result because the Hydra's used buss bars. What i did say is that there was more potential for sag or "modulation of the voltage" for the outlets later in the line because of this type of lay-out / wiring scheme.
If a device is plugged into the first outlet that pulls gobs of current on a dynamic basis, all of the outlets wired behind that first outlet will demonstrate at least a small amount of ripple. There is the potential for greater sag as the current draw increases. That's because the current will go where it is being drawn first and then whatever is left will "meander" downstream accordingly. If there is enough pull "upstream" at the first outlet, there's not as much current left to wander "downstream" to the other outlets. That lack of current is what causes voltage sag.
If you had multiple rivers ( individual outlets ) with their own feedpoints ( parallel branch wiring ) to the ocean ( wall outlet ), the potential for any starvation downstream is reduced. That is, so long as the ocean ( wall outlet and power cord ) could provide enough flow. That's because each parallel branch doesn't see what the other branches ( outlets ) are pulling whereas with the daisy chain arrangement, one river ( outlet ) feeds into the next in a series arrangement. If the first river ( outlet ) restricts the flow, all of the other rivers ( outlets ) feel the consequences.
Based on the info that you provided in this thread, this type of situation could only apply to the units that are wired in "daisy chain" fashion i.e. the 4's & 6's. As mentioned elsewhere in this post, the use of buss bars within the 8's still leaves me a bit confused though.
As to the link that you provided ( THANK YOU for making it simple for all of us to follow along ), i never, not once said that the Hydra's couldn't provide noise reduction. Anyone that has ever experimented with parallel noise suppression circuity would know better than to make such a claim. What i did question was the amount of isolaton as referenced over a specified bandwidth that the Hydra's provided from outlet to outlet. The test results that you linked to here didn't cover anything like that.
For sake of reference, my main concern is what happens when a component plugged into the Hydra generates AC noise / interference / RFI and tries to pump that back into the AC system??? Not only would such a test tell us how well each component is isolated from the other within the confines of the Hydra itself, it would also tell us the level of noise suppression that the unit is capable of providing for the incoming AC too. I hope that i'm clear enough in my explanation as to the type of info that i'm looking for.
Thanks again for the timely response and looking forward to any further info you would like to provide. Sean
