I am in in the mixing stage of a project now and I am going to be working in a space other than that which was being used for the recording. I want to take my same m-audio DX4 studio monitors (http://www.m-audio.com/products/en_us/DX4-main.html) to the new space to do the mixing but minus my interface, a PreSonus FirePod, I have no obvious way to connect my monitors to the MBP. The speakers have 1/4" TRS and RCA connections. I was using a stereo cable with 1/4" connectors to connect the monitors to the firepod (which I don't want at the new location - too much clutter) so could I just get some adaptor so that I can plug the stereo cable into the 1/8" line-out on the MBP? Would using my computers line-out be a bad idea for any reason? TIA!
