Subject:OT: additional outputs ??? Posted by: kbruff Date:2/27/2004 10:32:13 AM Hello Everyone -- I want to know if there is an audio component which can permit additional signal line level outputs. For example I have a main signal going in and then I want create (N) additional copies of that signal without subjecting the signal to noticable amplitude reduction? Is there such a device?

Do a search on them and you should be able to find several suppliers. On the other hand, since the output impedance of most line level audio devices is somewhere under 3K ohms, and the input impedance of most is over 30K (at least for non-balanced), it's quite possible to "Y" split the signal to a large number of devices before there is any noticeable deterioration. I've paralleled up to 9 recorders to a single source with no problems. Personally, i'd rather do the "Y" thingie for a small number of recorders than run the singal through another device.

I have passed this along before as a feature suggestion for Vegas, where you have a routing matrix which would allow you to route a signal to multiple outputs. I don't know of any software that will allow you to route a signal to multiple sound card outputs, but since you mentioned "devices", here a couple ways to do it. Well actually, I do know how to do this using Vegas and will outline that one for you as well. 1. The most commonly one used is to have an external hardware mixer, which I would recommend anyone doing audio work to have. You can route any fader signal to multiple output buses. The more buses the mixer has the more outputs you can route the signal too. 2. Using a patchbay. Commonly on a patch bay you can wire a "paralel" connection on mutiple patch points. So basically you connect 4 or 5 patch points together. You connect one output signal to the paralel connections and then use the other paralel connections to feed multiple inputs of other devices. A more simplied version of this is using a "Y-chord". 3. Using Vegas. Let's say your common signal you want to route to multiple outputs is on Track1. You can create AUX SEND buses in the mixer section. Assign each aux send in the master section to the different outputs on your sound card. Now goto Track 1 and the individual sends will appear where the volume label is. Turn each of these sends to 0dB, and assign them to Post Fader. So now your signal on track1 will follow the volume of the main track fader and it will goto multiple outputs at the same level. You could even do this with an input signal by enabling input monitoring in Vegas, then the input signal would be routed to all the aux send buses and what ever output you have assigned on the track fader.
