Dear Tapio,
Do you mean that on all HDCAM (750, 790, 900) and (maybe DSR series), you can have a stereo return from earphone? (I always thought that it was impossible and was compelled to monitor either channel 1, channel 2 or the mono mix). That would be a revolution for me (unfortunately I can't find the menu "page 06: HEADPHONE OUT (MONO / STEREO)" in the user guide of the F900).
Thxs in advance,
Best
Simon
