Plugging in multiple inputs to speakers
Posted by Patrick Simpson on April 18, 2009 at 7:38 pmI have a pair of Adam A5 speakers for my home studio. The A5s have both XLR and RCA inputs.
My question is this: can I have cables plugged in to both inputs at the same time? For example, I’d like to use the XLR inputs for my Pro Tools interface, and then use the RCA inputs to monitor the computer’s audio.
Theoretically, I wouldn’t be using both inputs at the same time – if it would make a difference.

April 19, 2009 at 9:54 pmThanks for the response but perhaps I don’t understand. Will it hurt the speaker or will it just not work? I didn’t see anything on the A5 technical data page that seemed to say.

April 22, 2009 at 9:46 pmWith all due respect, Sam, doing this will directly connect the outputs of the Pro Tools hardware with the outputs of the computer’s audio out. Those outs are not designed to be connected.
As for the manual not saying anything about NOT doing it, it probably also doesn’t say anything about not licking the power outlet.
I wouldn’t do it. But hey, go ahead, smoke test ’em. If you smoke either or both, my guess is the mfgrs will say you voided the warranty by doing something with the gear that was never intended to be done. I’d agree.

PS. Did I mention DON’T DO IT?

April 22, 2009 at 9:52 pmI just read through the product description and I didn’t see anything that stated that this would not work. I would give it a try. You won’t be damaging the speakers.
If it doesn’t work, there are products made for controlling the sound sent to monitors.

April 23, 2009 at 2:52 amThanks guys for the input.
I’m really not looking to smoke my two new monitors – that’s why I’m asking around before trying anything.
I e-mailed Adam (twice) and haven’t heard anything back. So I won’t be trying anything until I get some more definitive info.
I’ve thought of buying an inexpensive monitor controller, but I don’t like the idea of putting lower-quality circuitry between the signal and my ears. And it’s not crucial enough to spring for a more expensive unit.
Thanks again.

April 23, 2009 at 9:04 pmI’m curious what Adam suggests.
I see what you’re saying, Ty. I’m not an electrician. I guess there is some danger in connecting cables from device to device to device. The fact that these are modern day nearfield monitors with RCA inputs on them would lead me to believe that the designers likely foresaw that the user may plug multiple things into them, and therefore have some kind of functionality in place to handle this scenario.
Patrick, are you aware that you can use your Digi interface as your computer’s default soundcard? Click on the Apple and go into System Preferences > Audio > and then select the Digi hardware as the output. This way you can listen to iTunes through your monitors as well as your DAW.

I totally disagree with that. The added functionality serves the market in which the mfgr doesn’t know which of two commonly used outputs might be available to feed the monitors.

April 24, 2009 at 2:38 amMaybe I’ll try running system audio through the digi hardware.
While we’re at it… will I get better sounding audio going from my digi hardware (1/4″ outputs) into the XLR inputs rather than the RCA inputs?

1/4″ should be better if you use TRS 1/4″ to XLR cables. If you only use TS 1/4″ to XLR cables, the level will be 6 dB lower and because the signal is unbalanced, you might get some buzz.
