RCA to 3.5mm Conversion

I'm thinking about order a couple of these volume regulators:

After talking with a sale rep on the phone, I learned that this interfaces via an RCA cable, but the sound cards on my rigs only have 3.5mm connectors. I'm wondering if there is any reason that the normal operation of the regulators would be effected in any manner, if a converter was used at these sound card? The connection at the speakers are already RCA, so that shouldn't be a problem.

None what so ever. The signal will remain the same, the only difference will be the connection.

Go to radio shack and by the second cheapest mini-plug(1/8) to RCA coverter they have.

Thanks, that's what I thought, but wanted to hear it from someone else before ordering.

I found this thread too late to use it as I wanted, but I started another with a related question:
