External Mic Background Noise Reduction Level Selection |
(Radio Profiles, Audio Settings) |
Selects the level of background noise reduction that is applied to an external microphone. This selection applies to the current Radio Profile.
|
Noise Reduction improves voice clarity by reducing background noise. Noise Reduction occurs on the transmitting radio prior to transmission (in analog mode) and prior to voice coding (in digital mode). Not only does reducing background noise improve voice clarity for an analog mode transmission, in digital mode a cleaner speech signal going into the voice-encoder (vocoder) results in clearer voice being received and decoded in the receiver. |
When the Custom External Mic Noise Reduction Enable field is disabled.
Off |
Disables background noise reduction. The external microphone remains active, but no noise reduction is applied. |
Normal |
The external microphone continuously adapts to the voice signal for optimal clarity over a wide range of background noise. Recommended setting for most noise environments. |
Aggressive |
An increased level of background noise reduction is enabled. Recommended for VERY HIGH noise environments. |
Xtreme 1_Sided |
The Maximum amount of background noise reduction is enabled. Recommended for EXTREME HIGH noise environments, for example: Firefighter PASS alarm, low air alerts, pumper truck, gas fan, saw.
