[QUOTE="Ben Kennedy, post: 10103, member: 7262"] Hello all - I have a Zoom H1, which has a stereo line input. I have a cable that is 1/8" male to two 1/4" TS male connectors. I can successfully connect them to two Aux outputs on an Allen & Heath mixer, which has TRS balanced outputs. When I record, I successfully capture each Aux output on the left and right tracks. My understanding is that this because the "Hot" portion of each of the TRS Aux ports are getting connected to the Tip and Ring portions of the 1/8" plug, so it all works great. Previously I had been using a 1/8" to 1/4" TRS cable to attach the recorder to the mixer. This resulted in a recording that had the aux signal on the L channel (which I expected), but nothing on the R channel - when looking at waveform in Audicity, it is blank. Now, my understanding is that the Ring of the 1/8" was connected to the "Cold" side of the TRS Aux output. So why was my waveform flat? Is a cold signal incompatible with the analog-to-digital converter in my recorder? Or does it read it and suppress the output because it knows is actually connected to a TRS source? Or is the mixer clever about it and not sending anything to the recorder when connected that way? Thanks in advance for any insight. [/QUOTE]
