Air Line Arm Owners- Compressor Electrical Noise
Initially, yes. And, its not insanely difficult. The key- as many have repeatedly told me- is the ability to get the arm absolutely level- which means that once you level the platform that the TT is sitting on- you are using it with the XL, right?- you'll need the ability to further adjust the level of the platform with all 177 plus pounds sitting on it. Before taking delivery of the finite elemente stand, I set up the TT temporarily and achieved rough level using a half-assed system of shims. The finite elemente stand makes it far easier, since the pucks are adjustable from beneath the top shelf after the TT/arm has been assembled. ONce the stand arrived, I had Bill Parrish from GTT Audio come to set up the turntable properly. Mechanically, it worked fine with my setup but it sounds profoundly better after Bill Parrish did his magic. The VTA adjustment is now zero'd and I can make quick adjustments without tearing my hair out. We are using the adjustment mechanism on the arm itself, not the one that comes with the arm tower. Highly recommend competent setup just to be sure. And yes, I'd be curious to know if the compressor creates any electrical disturbances in your system. I'm still gonna follow up with Parrish and Markwell on that issue, even though,through the combination of the stepdown transformer and use of the Shunyatas, I may have eliminated the problem. |
Hi Whart, I have experienced the same problems. Problem can be solved by fixing a Zero switch Box in the compressor. Speak to your Kuzma distributor or you can call/e-mail Mr Franc Kuzma (386)42535450 / [email protected] and he can explain everything to you about the zero switch box. |
The electrical noise generated by the compressor when switching on, occures every few minutes and is similar to that which occures when a domestic refrigerator switches on. It is transfered via the mains not the air and can be solved by having a separate mains feed. If this is impossible or ineffective however, we have a "zero switch relay kit" which can be installed in the compressor and which normally solves the problem. Franc Kuzma,www.kuzma.si |
Thanks for the responses, gents. (Franc- you have been constantly responsive to me in the past, for which I thank you). Interestingly, I had the compressor wired to a separate receptacle, connected via very high grade wire to a separate breaker in a separate subpanel from the subpanel which services the audio system power. That, alone, did not prevent the 'zap.' I then plugged the compressor into an outlet on my 240v stepdown transformer, which seemed to reduce, but not entirely eliminate, the zap. I then plugged my electronics- all of them- into an Shunyate Hydra, which, combined with the stepdown transformer hook up for the compressor, seemed to do the trick. But, I will contact Scot Markwell for this zero switch relay kit, since it will enable me to have a little more flexibility in how my components are hooked up. Regards, |
