Positioning the HM60 Wind Instrument Mic
When positioning the HM60 wind instrument microphone, there are some general rules
that you should follow. Always position the microphone as close to the sound source as
possible. This is easy with the HM60 since the integrated gooseneck guarantees the mic
element is close to the source. Also, keep in mind that in order to minimize feedback
problems you want to position the microphone, (and if necessary yourself), behind the
main PA speakers. Be aware of a phenomenon called the proximity effect, which causes
a noticeable increase in low frequencies (bass response) when a microphone is close
to the audio source. This means that by making slight adjustments to the distance of
the mic element, you can get a change in the tonal quality of your sound. Keep in mind
that your sound is as personal as your playing style, therefore, you may find changing
the microphone position gets you just the sound you looking for. As with everything,
experience is the best teacher, so plug in and turn up and listen.
Here are some starting points to help you along the way.
Saxophone – Use the built-in clip to attach the ATX transmitter to the bell of the
instrument and position the HM60 mic about 1"–2"from the center of the bell. You can
move the mic out a little to get some extra edginess, or closer for some extra warmth.
Trumpet – Use the built-in clip to attach the ATX transmitter to the bottom of the bell
on the instrument. Aim the HM60 microphone towards the center of the bell, but since
the trumpet is capable of producing some of the highest SPL levels, start with the mic
element positioned away from the bell. Try bringing the microphone element in closer to
the bell for better isolation and more low frequency response.
Trombone – Attach the ATX clip to the bottom of the bell and position the HM60
microphone directly into the center. In this position you will get the maximum isolation
with full frequency response.
