    The O.P. was describing an audio level interface, or "Match Box"<br>
    <br>
    I use several Aphex 10/4 Model 124A or 124B.  Each has RCA in and
    out, as well as XLR in/out, and then for 1/4 inch TRS applications,
    I use XLR to TRS cables or adapters.  I then use RCA to 1/8" stereo
    cables for connecting to the equipment.  these get constant use on
    our mobile gigs or connecting iPads and phones and other portable
    use to PA systems either through the FoH board, or directly to a PA.<br>

            if what I'm looking for exists, or if perhaps there's an<br>
            easier solution I'm not thinking of.<br>
            the problem: We often have people come in with multiple
            laptops,<br>
            iPads, etc to hook-up to our sound console - Soundcraft
            Performer 3.<br>
            We currently have a pair of Radial ProAV2 DI boxes.  They
            work well.<br>
            The issue is that we are taking up 4 inputs and 4 faders
            with them to do this.<br>
            The console has four 1/4" line level inputs that map with a
            single<br>
            fader stereo channel.<br>
            <br>
            So ideally I would love a balancing transformer that has
            unbalanced<br>
            stereo 1/8" or RCA inputs and a pair of balanced 1/4" TRS
            outputs,<br>
            with pad and ground-lift options.<br>
            <br>
            Eela makes something very close to what I want, the EA926/T

              target="_blank">http://www.eela-audio.com/Line_Interfaces.html</a>
            but it has XLR outputs.<br>
            <br>
            Does anyone know of something like what I'm describing?<br>
            Or if I got the Eela unit and used XLR to 1/4" would I have
            impedance<br>
            and level mismatch problems?<br>
            <br>
            Thanks,<br>
