Hi All,

Back again with more questions. I got an Audio Technica short-shotgun mic and an ATR3350 lav mic to go into a Scarlett 2i2 interface. The XLR works great but the lav is inaudible. The mic itself works well as tested through other devices but nothing is coming out of the Scarlett.

There are three potential issues I know of and who knows how many others. I'll start with what I know. The ATR3350 is said to be dual-mono -- I'm guessing both the tip and ring are connected. I'll check the continuity when I get home. I'm trying to plug that into the Scarlett with a stereo 3.5mm to 1/4" adapter. I'll check the continuity on that too. Would I need a dual-mono 1/4" adapter?

The second possible issue is impedance. The lav is 1k ohms. The shotgun is 100R. I know there are high-2-low Z adapters but don't know if those are the fix.

The last known issue is phantom power. The Scarlett has that available but it only works on XLR pins. I've been trying the 1/4" jack in the middle. If any potential adapter comes with a 3.5mm-2-XLR form factor, does the phantom power (necessary for the shotgun) mess-up the little batter-operated lav? Rode has the VXLR adapter which seems to be just a re-pin device. The HOSA MIT-129 looks like it has a mini-transformer inside to change the impedance. In looking around the net some folks say the adapters work well but I haven't found any comments on +48v coming in on the pins.

As always, any ideas are welcome. If this is a lost cause, you won't hurt my feelings by saying so. Thanks, sh
