N3's
I should mention that this company was a low impedance company for many, many years. Whenever a new type came online regardless of what it came with from the factory, it was converted to low. This changed when the S76C+ was introduced. All 76 A, A+, A++'s low, C+, C++ high.
The company finally started to switch over to high impedance on most types (139 for example). However, this is not a hard and fast rule, as I'm told by a friend who is on a brand new 225 that it is low impedance. This caused a bit of a problem both logistically and financially as pilots who might fly 2 types needed to carry both mics for a Bose, or use a DC that had a conversion switch.
