Thanks millercarbon and lowrider57 for your thoughts around the positioning of the dedicated audio lines on the electrical panel. I live about 1/2 mile from a large radio tower and pollution is a true concern.
As these things go, two days ago I began sampling a set of Varastarr Grand Illusion Evo Series 10' speaker cables that belong to a friend. Varastarr claims RFI within and without one's audio chain is addressed by having their cables on-board. Proof's in the puddin'...yep, more of my truth and these are stayin' put! More Peace, Pin

he reworked the single panel, keeping the larger draw appliances "away" from the music lines in, on the opposite side of the panel.
Well, that’s a new one.
Behind the panel where most never look are two great big bus bars. All the breakers attach to the bus bars. These things are so thick it can’t matter where on the bar you take off. How about the magnetic field surrounding the breaker? Will the magnetic field be stronger in a higher current loaded breaker than one with a small connected load? How about them harmonics on the circuit? All the circuits, every single one of them, they are all just as electrically connected to every other circuit on one side as on another. The only thing putting a lot of them on one leg can accomplish is to draw more from that leg. What’s the average connected load of a typical audio system? 8 to 10 amps tops? Why install all dedicated circuits on the same Line, Leg? "Less than 300 microamps of ground loop current can cause hum as it flows in an unbalanced audio interconnect cable. However, harmonics of 60Hz that are generated from lighting dimmers or switch-mode power supplies sound like Buzzz mixed with a bit of Hummm and are more easily coupled by even smaller currents. Harmonics can add together when equipment is powered from different phases, so clearly there is an advantage to specifying same-phase electrical service to power the electronics systems in most cases....
Any leakage currents on the safety ground wires of split single phase load circuits fed by different phase legs will add together due to the 240V potential difference....
Power conditioners do not solve any of these common problems: Cross phase coupling (doubles hums & buzzes) .... What actually does solve them: Same phase power.
.
Split Single Phase electrical service is most commonly found in residences and smaller commercial buildings, and is commonly used to feed AV equipment. One key advantage that single phase has over three phase is that while harmonic currents are still present, it is not possible for the �triplen� components to add in the neutral. In addition, use of split single phase can result in at least a 6dB reduction in noise floor as compared to three phase if the capacitances of the connected equipment are relatively well balanced. However, any leakage currents on the safety ground wires of split single phase load circuits fed by different phase legs will add together due to the 240V potential difference."

Hi guys
Finally I will install tomorrow a 8/10 AWG (6 mm2) dedicated line for my system, using a 20 Amp breaker and plugging the line directly to the main breaker on the street.
I will only connect my system to the line, not the subwoofers.
I will let you know the results ASAP.
PS: the system wich will be connnected to the line:
Holton DC Blocker
Bada LB-5600 Power Filter
Wyred4sound USB Reclocker
Gustard U16 USB converter to I2S
Audio-GD R8 DAC
Audio-GD Master 1 preamp
Nord Acoustics NC500 stereo power amp (class D)
Q Acoustics Concept 500 floorstanders |
I don't understand how you can connect to the AC line on the street. Is that how a residence receives power in your country?
|
I'm sorry, may be I expressed it in a wrong way.
I will connect the line to the main breaker of the Electrical Company who supplies me the service. Not the street!!! I meant I will by pass my house's main breaker.
I will connect a dedicated positive, a neutral and ground. The latest will be connected to a new copper bar, wich I will bury on the ground. |
