Low Cut; Auto Gain Control (Rx Audio Response) - Kenwood NEXEDGE NX-200 Function Reference

6 SOUND
6.7 Adjusting Audio Characteristics (NXDN System only)

Low Cut

Low Cut can be used to cut off the frequencies outside of the audible frequency band when the transceiver receives a
signal in Digital Mode.
The received audio may not be clearly audible in Digital Mode when a user communicates using an earphone or while
communicating in noisy environments.
In this case, frequencies of 300 Hz and lower can be cut off in the receiving transceiver using Low Cut. By this, the sound
of the received audio in Digital Mode will be similar to the received audio in Analog Mode; hence, the received audio may
be understood easily.
Audio Response
Enabled While the transceiver receives in Digital Mode, audio frequencies of 300 Hz and lower will be cut off.
Disabled Audio frequencies of 300 Hz and lower will not be cut off even if the transceiver receives in Digital Mode.
Note
The transceiver enters RX Low Cut Mode by a user pressing the Menu key to enter Menu Mode, and then selecting "RX Low Cut". In
RX Low Cut Mode, the configuration for Low Cut can be changed.

Auto Gain Control (RX Audio Response)

Auto Gain Control is the function to adjust the volume level of the received audio. The received audio sounds better by
amplifying or attenuating the received audio.
The volume level of the received audio may vary depending on the voice level of a user talking to the transmitting
transceiver and the distance between the microphone and the mouth. In this case, this function allows a user to hear the
received audio clearly since the received audio is automatically adjusted to a certain volume level according to the
configuration for the volume level.
Auto Gain Control
Auto Gain Control (RX Audio Response) is disabled and the volume level of the received audio cannot

automatically be adjusted.
Auto Gain Control (RX Audio Response) is enabled and the volume level of the received audio can automatically
High be adjusted to a certain level according to the configuration for the volume level. However, a background noise
of the received audio may be played back loudly, or a howl may occur.
Auto Gain Control (RX Audio Response) is enabled and the volume level of the received audio can automatically
be adjusted to a certain level according to the configuration for the volume level. However, the volume level to be
Low
controlled will be lower than that of when "High" is configured. Therefore, the range of the volume level to be
automatically adjusted will be narrow, but the less effect on the background noise and howl will occur.
Note
• If the Auto Gain Control (RX Audio Response) is disabled in the receiving transceiver but Auto Gain Control (TX Audio Response) is
enabled in the transmitting transceiver, the volume level of the received audio will automatically be adjusted to an equal level.
• The transceiver enters Menu Mode by a user pressing the Menu key, and then the transceiver enters RX Auto Gain Control Mode by
a user selecting "RX Auto Gain Control". In RX Auto Gain Control Mode, the configuration for Auto Gain Control (RX Audio Response)
can be changed.
