KE 4-211-2 replacer

Hi all,

Currently we have an old PCBA which consists of a "KE 4-211-2" with a preamp.
As you know the "KE 4-211-2" is obsolete.

Does anyone know a replacer for this microphone which has ~same spec (freq response/operating voltage/SPL)?

Thanks.
 
You would need to find an equivalent that is electric condenser microphone with a built in impedance transformer ---Sennheiser I know a good quality company their headphones used by EU governments as well as the hi-fi world --I owned a pair at one time.
