Intelligibility - AKG C1000 S Modo De Empleo

To increase usable gain before feedback, the microphone has a cardioid polar pat-
tern. This means that the microphone is most sensitive to sounds arriving from in
front of it (your voice) while picking up much less of sounds arriving from the sides
or rear (from monitor speakers for instance).
• To get maximum gain before feedback, place the main ("FOH") speakers in
front of the microphones (along the front edge of the stage).
• If you use monitor speakers, be sure never to point any microphone directly at
the monitors, or at the FOH speakers.
We recommend slipping the PPC 1000 Polar Pattern Converter on the capsule
to change the microphone's pickup pattern from cardioid to hypercardioid.
This makes the microphone even less sensitive to sounds arriving from the
sides and further increases gain before feedback.
Feedback may also be triggered by resonances depending on the acoustics of the
room or hall. With resonances at low frequencies, proximity effect may cause feed-
back. In this case, all you may have to do to stop the feedback is move away from
the microphone a little.
• To ensure high gain before feedback, never cover the rear sound entries (1)
with your hand. This would destroy the cardioid/hypercardioid pickup pattern
and cause the microphone to pick up sound from all around, the result being
sharply reduced gain before feedback.
• In order to optimize the intelligibility of speech, you can slip the PB 1000 Pres-
ence Boost Adapter on the capsule (refer to section 3.1).
