Shunyata Power Conditioner advice

Lacee:

I'll check this out:

"If someone claims that adding dedicated lines created hum or noise, then perhaps it's a bad electrical connection at the panel,the lines are not all on the same side or phase of the panel or that some noise inducing appliance such as the funace AC or refrigerator share close proximity with one or all of the dedicated lines at the panel.

Have an electrician come over and see if he can balance out the amount of draw each half of the panel has."

Since I did all wiring in our house, including panel connections, I'm the one to blame if my two dedicated lines are out of phase!

Hello Tarjin, please feel free to e-mail us with questions. I don't look in here often enough due to work and travel to be consistent in reply.

The primary cause of hum related to the use of dedicated lines is a difference in potential to ground caused by running differing lengths of wire from panel to outlet. If your furthest outlet requires a 25 foot run of wire from the panel, you need to use this length for any additional dedicated lines even if they are much closer to your AC panel. Make sure the gauge and breaker are rated the same and if possible on the same electrical phase. This will minimize the likelihood of ground-loop related hum.

Best regards,

I recently got (2) Shunyata Hydra 4. It is my understanding that each set of ports are isolated from each other. I have the following items connected. To the first unit, first set of ports are the PSU's from two HDD and the second set have the Dish Network satellite box and my HDTV. On the second Hydra one set of ports are connected to my Mac Mini and my DAC. The second set of ports are connected to my amp and my REL sub.

Does this connection scheme seem reasonable or would you connect with another combination and why?

Mwheelerk,
I have a Hydra 4, FWIW. To answer your question(s), as I understand it from users of more than one Shunyata conditioner the idea is to separate the analog from the digital equipment. Your set up sounds close but still mixes amp./sub. (assumed analog) with digital Mac/DAC.
Ultimately, you may not actually hear a difference, but this is the theory. Other factors that will influence your outcome are the type (and brand) of power cords you use. From my experience upgrading power cords on the Hydra 4 has always been noticable. For your future info, the folks at Shunyata (Customer Service) are very approachable with concerns such as yours. Likely it is not the first such question on best usage of this type.
