Mic EQ

Five Top Tips – Setting Microphone Equalisation

Equalisation (EQ) refers to the adjustment of the relative levels of different frequencies within an audio signal. Whilst EQ is unlikely to make a poor mic sound good, it can make a good mic sound better, particularly if adjusted for each user:
  1. If you have a good quality microphone, equalisation may prove to be more of a headache than benefit – presenters love to fiddle with EQ, generally to make their voices sound richer in low frequencies – but what they think sounds great in their headphones can often sound poor when broadcast.
  2. If you do have a mixer or processor with EQ, it is a good idea to prevent access by people who don’t know how to use the controls.
  3. Ideally, the equalisation will be optimised for each user, which requires some form of memory and recall.
  4. When adjusting the EQ it is best to listen via quality loudspeakers. Ideally the mic will be in its ‘final’’ room however listen on speakers in an adjacent area to avoid feedback.
  5. Take care when ‘boosting’ certain frequencies to ensure you are not causing an overload. This will result in distortion.

And a bonus tip:

The voice range does not include very low and very high frequencies, which the microphone will pick-up; consequently if your EQ allows you to attenuate the very low and very high frequencies, the microphone will be less sensitive to picking up external unwanted frequencies.

Not only do Clyde Broadcast’s engineers know eveything there is to know about EQ and getting the best sound from your station, but they have developed innovative ‘VoiceBand’ technology into the INTEGRA system. Click here to discuss your radio project with our team.
