Author Topic: place to buy audio switches Jeff Else Expert Film Handler Posts: 125 From: Detroit, MI, USA Registered: Nov 2006 posted 02-07-2010 12:34 AM                     okay i'm having trouble finding this just googling for it so i thought i'd ask.. i'm looking for a place to buy a two channel, two input switch that switches signal AND ground, like this one... http://www.dact.com/CT3_data_sheet.PDF (although this one is for 5 inputs) but this one costs about $90! it doesn't need to be as fancy as this seems to be, just with signal and ground switching for two stereo inputs, and i'd like not to use some a/b rca box from radioshack. thanks  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 02-07-2010 02:34 AM                     Well, don't knock "Rat Shack" too much. Go buy a project box and two DPDT switches and RCA female connectors so you can "A/B" both ground and signal with your own homemade box - if you know how to solder.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

A 5 position 4 pole switch that is gold contacts is going to cost! With electromechanical today...I wouldn't switch ANY audio without gold contacts. For what you are doing, a MTA406P04 might do the trick. It is a 4PDT gold flash mini-toggle switch.

Sound like a good way to get pops and hum while switching.  |  IP: Logged Jeff Else Expert Film Handler Posts: 125 From: Detroit, MI, USA Registered: Nov 2006 posted 02-08-2010 12:49 PM                     i'm trying to avoid creating ground loops... i don't know much about the science of avoiding ground loops so i could be wrong...  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 02-08-2010 05:16 PM                     Yea, for there are two basic kinds of ground usage - chassis and earth and you don't want to really mix the two. Thus doing ground switching is a good way to go. ..or, you could peek into ground loop isolators when it comes to audio input signalling. -Monte  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 02-08-2010 05:26 PM                        Here is a gold plated switch that only requires a breakout cable (DB25 to whatever your equipment requires). And they are not wildly expensive. 2 Port DB25 Switch at Cables-To_Go  |  IP: Logged
