I'm using a new Azden WR-Pro wireless receiver with the Azden WM/T-Pro handheld mic connected to a mini-to-RCA Y cable and plugged into the Audio 2 RCA jacks on the side of the XL-1 handle in 12 bit 4 channel mode while the standard XL-1 mic also records with it's own dedicated jack. Recording seems to be working fine- I get successfully recorded audio on from both mics when I review in playback mode with the mixer BUT the audio from the Azden wireless mic is only coming on one channel- either the left or right- depending on which RCA input I plug the black end of the Y cable in.

Is there something I am missing or have I just missed the obvious which I can't find in the Azden spec sheet - such as this inexpensive Azden wireless mic setup simply isn't stereo capable?

The WDR-Pro and WMT Pro are monophonic.

The WR-22 Pro with two mics can be connected for a stereo output

Thanks Don. I'm aware of the WR-22 Pro. I had mistakenly assumed that the WDR-Pro and WMT Pro would output stereo sound on the two channels. I coulnd't find any mention of them being monophonic on the included documentation. Are there single handheld mic/receivers that do output stereo sound? Or should I just double the sound I recorded with the wireless mic in Premiere to simulate the stereo effect?

Panning the sound to both channels in post is a reaonable way solution. Alternatively yu cdould usa "Y" adapter fromtheWDR-Pro output top feed the same signal to both XL1 channels. But is is stilla mono signal.

You can play with gain settings and equalization for each channel to simulate stereo sound.

The WDR-pro has two antennas and receivers in it for diversity to ensure reliable reception in venues with multipath problem. It sends the best signal to the output

There is no way to get true stereo sound without at least two mics, (or a single point stereo mic). The WR22-Pro and two mics/transmitters may be your best bet for modest cost stereo, or buy a second WDR-pro and mic and use them on the alternate frequency.
