C 1000S
Condenser Microphone
Description
The AKG Model C 1000 S gradient condenser microphone
uses a low noise pre-polarized backplate (electret) and is
ideal for a variety of recording and sound reinforcement
applications. Its polar pattern can be quickly converted from
cardioid to hypercardioid by placing an acoustical converter
over the end of the microphone capsule; this has virtually no
effect on the on-axis response of the microphone. The on-
axis response of the C 1000 S has a gentle (-6 db/octave)
roll-off below 200 Hz which has been tailored for the normal
close-in use of cardioid and hypercardioid microphones in
studio recording and sound reinforcement applications. The
microphone may thus be used in close-in application with no
need for further equalization. The C 1000 S may be powered
by a 9-volt battery or by phantom powering over a range
from 9 to 52 Vdc. The included PPC 1000 Polar Pattern
Converter allows quick changeover from cardioid to
hypercardioid. A silent on/off switch is recessed to prevent
inadvertent shut-off. The included Presence Boost Adapter
piece PB 1000 creates an emphasis of the higher frequencies
from 5 to 9 kHz by about 3 to 5 dB, which not only improves
the transmission of sibilances but may be also advantageous
when recording instruments requiring greater high frequency
content in their audio spectrum.
