Audio Circuit and Body Mounting Tips
The audio circuit is based on a DTC proprietary automatic gain control (AGC) hybrid
circuit and an external, high-sensitivity Knowles electret microphone. Excellent audio
quality is achieved in a wide variety of background noise environments.
All body-worn transmitters are susceptible to “clothing noise”. Reducing this rubbing
effect is accomplished in a variety of ways. After securing the transmitter to the body
with a secure mounting method such as an ACE bandage or custom harness:
1.
Try to locate the microphone in an area that pickup will be best and rubbing noise is
least. Avoid the arms, legs, crotch or under the arms or the waist area. Front torso
mounting is ideal.
2.
Always provide a small amount of strain relief on the microphone cable itself. This
reduces the noise caused by the microphone cable and element being tugged and
prevents cable damage.
3.
Secure the microphone cable to the body with medical adhesive tape in at least two
spots, the final being about an inch below the element. Remember to leave a strain
relief loop!
4.
Completely cover the microphone element (facing outward) with an ordinary Band
Aid™ . This provides a damped baffle for the microphone and a slick surface for
clothing to rub on, and actually does not impact audio pickup level at all.
