I have received my new Sony PMW-400K with DWR-S02D two-channel portable slot-in receiver which allows the PMW-400 (together with the 2 x Rear XLPs) to accept 4 simultaneous channels of audio, but I don't see a way in the manual or the camera that you can monitor all 4 channels together.

The "Ch1/Ch3 - Mix - Ch2/Ch4" slider button does not seems to mix all 4 channel even when set to "mix".
Does anyone with a Sony PMW-350/400 know if it's possible to monitor all 4 audio channels through headphones?
Thanks

Pretty sure you limited to just 2 channels at any one time.

Thanks Alister, you don't have or aren't planning any training on this camera, as I sure be keen on that?!

2 channels only via headphones.

On a PMW 500, you can monitor all 4 channels of audio on the LCD display screen on the side of the camera. You just need to press the display button until the audio meters come up.

I would have thought the PMW 400 would be the same?
