Damn it, I've been thinking that the 50 also had a wider frontal pick-up
than the 40; I've just been and checked the graph plot (first time in years=
)
and you're right. And yet it has sounded ... if not wider, at least 'bigger=
'
in combination with the 30. I'm going to have to investigate these 2 set-up=
s
again. In theory the 30/40 combination should be the better choice in
certain situations where I've been using the 30/50. Spain at the end of
April should be ideal for some comparisons: soundscapes of the dry
rocky/sandy canyons of inland Valencia.

Yes, agreed. Though I've never fully grasped what happens to sound picked u=
p
ONLY by the side mic. As I understand it, it's the sound to left and right
picked up by BOTH mid and side mics that provides the exclusively L or R
signal, when matrixed. The maths looks so simple, but I've always struggled
to interpret it.

For walk-about stereo I use a short (5m) cable to avoid this. Put the mics
down on their small tripod, then just back off slightly to reduce shuffling=
,
breathing and machine noise.
