[QUOTE="Geoff Doane, post: 47894, member: 1155"] Re: Whirlwind Contractor Splitter Used Backwards? Sounds like the wrong tool for the job was used. The installer simply bought an off-the-shelf product (that he may have used in the past), when a simple punch block would have sufficed. There is nothing wrong with simply multing the two MASS connectors if they are only going to be used for analog audio. If there was AES or DMX on there, there might be problems, but analog will never know the difference. I would double-check that it is connected the way you describe. If the console really is on the ISO output, it can't supply phantom to the mics. Whirlwind has a 48V supply that can supply phantom, but of course it isn't controlled by the console. Does it actually have transformers installed? Maybe they just jumpered the appropriate terminals, and everything is paralleled on the board already. In that case, it should work fine with no loss from either input to the console, and the console would supply phantom. If the audio level seems low, do some testing with a tone generator to confirm (or disprove) it. GTD [/QUOTE]
