4.15 NOISE CANCELLATION
XL Mobile radios feature Harris’ proprietary noise suppression capability to provide clear and crisp voice
quality in high-noise environments. This can be used in any mode, including analog and digital
communications.
The standard mic has two microphones; one located at the top (voice) and one on the bottom (noise
reference) (see Figure 4-6 and Figure 4-7). When noise cancellation is enabled, voice is picked up by the
upper microphone, and noise is picked up from the bottom microphone.
In the case where noise cancellation is enabled and the bottom (noise reference) microphone is blocked, the
radio operates as though noise cancellation is turned off.
