The 4038 Studio Ribbon Microphone is of British Broadcasting design (BBC)
and used for broadcasting and recording such sounds where a clear smooth
wide range frequency response, absent of transient distortion and relatively
high sensitivity is essential.
The 4038 has a proven reliable performance capability, being since its
introduction, used by broadcasting networks throughout the world such
as the BBC.
The frequency response of the 4038 is exceptionally flat from 30 to 15,000
c/s and throughout this range the shape of the bi-directional (figure
of eight) polar response is maintained substantially constant both in
the horizontal and vertical planes, giving a natural smooth sonic quality
textured response to sound signal being picked up.
Studio microphones have now achieved a remarkable fidelity of reproduction.
If the microphone is not close to perfection, there is no point in having
expensive systems to take the sound the rest of the way to the audience's
ears.
In the world of sound, the BBC has always been the leader, and is still
regarded as the 'setter of standards'.
