with the Microphone Sensitivity setting to configure transmit audio. Adjust the Microphone Sensitivity to

achieve audio quality and then Input Gain to add volume. Too much Input Gain, however, can cause audio

to be distorted.

7. From the VAGC dropdown, select whether to enable the Voice Automatic Gain Control for the jack box.

For more information, see "Configuring an Audio Device's VAGC" in the Scout Manager Online Help.

NOTE

Voice Automatic Gain Control (VAGC) helps separate transmit voice audio from noise audio to improve

voice clarity. For example, when VAGC is enabled, audio from a soft spoken dispatcher and audio from a

loud dispatcher each present more consistent audio to the field.

8. If VAGC is set to ENABLED, from the Noisy Environment Compensation dropdown, select whether to enable this

setting to improve VAGC performance in a noisy dispatching environment.

9. In the Output Level (dB) field, enter the level of the audio coming from the media workstation to the jack box.

Range: –40 to 0 dBm. Default: –10.

10. From the On-Hook Switch dropdown, select ENABLED to indicate that a hook is connected to and used on this

jack box. Default: DISABLED.

11. Under the Device Settings section, in the Microphone Sensitivity field, set the microphone pick up level in the

jack box. Range: 0 to 15. Default: 0.

NOTE

A more sensitive setting (15) picks up a wider range of audio than a less sensitive setting (0). Consider

turning the Microphone Sensitivity down to a lower number if the audio is too loud or distorted when

received in the field. Conversely, consider turning this setting up to a higher number if the audio seems too

low in the field. This setting applies to transmit audio and helps add clarity by helping to normalize

differences that could occur because of physical distance to the microphone or differences in voice quality.

For example, a dispatcher who uses a desk microphone but turns away from it frequently, taking the voice

audio "off axis," can benefit from a higher setting. Use in conjunction with the Input Gain setting: Adjust the

Microphone Sensitivity to achieve audio quality and then Input Gain to add volume.

12. From the Microphone Boost dropdown, select 20 dB to increase the level you set in the Microphone Sensitivity

setting by 20 dB. Default: NONE.

NOTE

The Microphone Boost setting works in conjunction with the Microphone Sensitivity setting to increase the

gain, if necessary. When set to NONE, this Microphone boost is off, and the audio passes through without

changes. Choosing 20 dB turns this feature on and gives the audio 20 dB of gain. This feature is most often

used for headset audio; use caution when configuring for a handset.
