Connector Cables
To connect the cable to the headset:
• Choose the right cable and connector that works with your wireless system.
• Line the cable up to the threaded terminal
on the back of the QEx and screw the cable
into the headset.
• Do not over tighten the cable.
• Attach the included collar clip on the back
of your shirt collar and run the mic wire from
the QEx Fitness Headset to the wireless body
pack. Leave enough cable to allow you to
turn your head from side to side.

Mic Positioning
The correct way to wear your QEx fitness headset microphone, is over the ears, as you would wear
a pair of eyeglasses. To avoid feedback problems, take care not to cover the microphone capsule
with your hand.
Note: If wearing glasses, it is recommended to put the QEx microphone on first than place glasses
over the microphone.
Position the QEx microphone element about
0.25” –1” behind the corner of your mouth. To
avoid breath noise and p-pops, use the included
windscreen.
If the microphone is too far away from your
mouth you will need to increase the gain and
reduce isolation.
To minimize additional noise, do not locate the
microphone tight against your cheek.

Using the QEx
The QEx Fitness Headset employs noise canceling techniques to provide noise reduction, improve
clarity and gain before feedback. These techniques allow the QEx to be used in environments and
facilities where the sound system might not be optimal. First, the small size of the microphone
capsule and the short distance between the microphone and the mouth reduces the sensitivity at 1
kHz for far field noise by 10 dB. And noise at lower frequencies is additionally attenuated. Finally,
the bi-directional polar pattern reduces signal coming from a 90° angle by 15 dB compared to
signal originating from directly in front of the mic capsule.
