Default Polar pattern mysteries...

Well that was all very interesting Plowie, but I'm not sure what the
point of it was - my questions were specifically in respect of a
'multi-pattern tube mic' (as above)...??


Sigh. That's what I was trying to explain. The various patterns are a
combination of omni and figure of eight capsules outputs added in
different amounts. Which can be done by 'a' switch on the capsule or
elsewhere. With a valve mic you need a power supply with multi-core cable
so it makes sense to have the DP switch on that - handy if the mic is
slung out of reach. Early valve mics like the AKG C12 had the same sort of
arrangement.

A solid state mic would be phantom powered off the mixer etc - only a
normal (twin and screen) mic cable - so the DP switch is normally on the
mic itself.

But on second thoughts I should have saved my typing fingers.
