hi,
what a pitty, the 18db are a-weihted. not so good, i think..
here is what sanken wrote me:
Yes, equivalent noise level of CSS-5 is less than 18dB.
It is A-weighted. Sanken standard stated that it is at "IEC 179".
However, we do not know its relation to CCIR.
IEC179? any differents to IEC651?
by the way, i will make a comparison hopefully tomorrow between the
sanken css-5 and two sennheiser mkh50.
(best comparison would be with a mkh50/30 combination. but i don=B4t
know anyone who has a mkh30..)
we will see...
all the best
