Joshua Anderson Posted November 5, 2013 Report Share Posted November 5, 2013 Hey all, I want to send 5 volts continuously down the "positive" leg of a Canare Star Quad cable. I'm assuming that is completely fine as Phantom power would be sending 12-48 volts. Phantom Power sends a continuous charge at a higher voltage than I'm looking to do, so I should be fine...? Maybe the info is in front of my face when I check out the Canare Star Quad specs: http://www.canare.com/ProductItemDisplay.aspx?productItemID=53 But all I see is that Star Quad has a max voltage of 500V AC and at only 1 minute. I want to continuously send 5 Volts of DC. This is for a remote control, but I would like to use Star Quad cables so I don't need a dedicated cable for this application. Any advice on max voltage on Canare Star Quad is appreciated. Thanks, Josh Quote Link to comment Share on other sites More sharing options...
rich Posted November 5, 2013 Report Share Posted November 5, 2013 i have made powered output cables for audio 2040's that carry 12v on a core of the mogami 2893 quad cable with no problem. dont imagine that your intended use will require that much current so i would think that you'll be just fine.

" what continuous charge ?? time to study Ohm's Law... it isn't about the voltage, it is about the current! Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted November 5, 2013 Author Report Share Posted November 5, 2013 "Charge" is probably not the correct term. And here's where I'm guessing...I think the device compares the differences in voltages between a constant 5 volts on one leg and a variable voltage between 0 and 5 volts on the other to determine control "remotely." I don't have watt or amperage numbers, nor am I sure where they fit into the device's requirements for a remote control, as it is not in the manual.

soundslikejustin Posted November 5, 2013 Report Share Posted November 5, 2013 FYI, phantom power is 48v, but at only 10mA. In other news, you'll be fine sending 5V DC at up to a couple of amps. Quote Link to comment Share on other sites More sharing options...

(ever see auto battery jumper cables for 12VDC ?) Quote Link to comment Share on other sites More sharing options...

I have also seen an Apple iPad charger cable that carries 5V @ 2amps. Yes, it's short, but it's very thin cable that doesn't get hot. Considering OP is making a remote control cable (which means it's most likely less than 6 feet) and that also probably means it's GPIO (which is low current 5V) I stand by my post.

Rick Reineke Posted November 6, 2013 Report Share Posted November 6, 2013 I'm sure you'll be fine sending low amperage current through the 21g Canare L-4E6S Star-Quad mic cable . If it starts to get warm, (which I doubt it will) switch to a heavier gauge Star Quad speaker cable. Quote Link to comment Share on other sites More sharing options...
