The C 747 is a tiny directional microphone designed for
exacting orchestral, choir, podium, and boardroom appli-
cations. Flat, extended frequency response makes it suitable
for high quality live music recording, while the frequency-
independent pattern provides consistent off-axis rejection to
control ambient noise and feedback in acoustically difficult
environments. With its hypercardioid pickup pattern, the
C 747 is an excellent microphone for noisy discussion groups
or reverberant pulpits while it is forgiving enough to clearly
pick up talkers moving around in front of the microphone.
A switchable LF cutoff filter suppresses mechanical noise.
The low-impedance transformerless preamp operates off
9 to 52 V phantom power. Standard accessories include a
shock mount/adapter, windscreen, mini gooseneck, stand
adapter, mounting clamp, and thread link.
