NI Komplete Audio 6, inputs 3/4 problem

Hi all,

I'm trying to connect the RCA record out on my mixer to inputs 3 and 4 on my Komplete Audio 6. The KA 6 only has 1/4" balanced inputs for 3 and 4, so I got some RCA to 1/4" TRS adaptors from monoprice:

When I hook it up, I get no audio coming into inputs 3 and 4 at all.. the LEDs don't come on at all, and the inputs in Traktor don't register anything. These adaptors are fine with the KA 6 though, as I use the same ones for outputs 1/2 and 3/4 to go into the mixer.

I happened to have another mixer kicking around that has balanced 1/4" outs for its master output, so as a test, I ran the record out from my main mixer into a channel on that, and hooked up the master 1/4" outs on the second mixer up to inputs 3 and 4 on the KA 6 using 1/4" cables, and got LEDs and audio input right away.

Anyway.. all that to say, has anyone else had problems using RCA to 1/4" adaptors on the inputs on the Komplete Audio 6?

Thanks!
