AM360r User Manual

Hardware Rev. A 

Firmware Version 1.00.20

Transmit Gain

 accepts a number from 0 to 63 representing 64 steps of attenuation or gain 

in the audio path from the IP network to the attached radio transmitter. Level 0 represents 

the lowest audio level while 63 represents the highest audio level. Follow the procedure 

specified in your radio’s technical manual to set this to an acceptable level.

VoIP to Transmitter Mode

 determines whether the AudioMate 360r will allow two-way 

audio flow or prohibit transmission entirely.

OFF

 disables the AudioMate 360r from keying the attached radio transmitter. Use to 

prohibit transmission entirely in listen-only applications where the radio should never be 

keyed under any circumstances.

Half Duplex

 allows transmission over the attached radio, but will not stream receive 

audio during transmission. Select this when attached to a control station radio.

Full Duplex

 allows transmission over the attached radio while simultaneously sending 

receive audio back to the IP network. Select this when attached to a full-duplex repeater 

station.

ON

 keys the attached radio transmitter full-time regardless of the signals from the IP 

network.

PTT Delay

 (Hang Time) sets the time period between the end of the IP network stream and 

the release of the PTT signal by the AudioMate 360r. This can be useful if the radio unkeys 

before all the audio has finished playing out of the buffer. Acceptable values for PTT Delay 

range from 0 to 25.5 seconds in increments of 0.1 seconds.

PTT Timeout

 sets the maximum duration of a transmission to prevent the attached radio 

from typing up the channel, such as an stuck footswitch on a console on the IP network. 

Acceptable values for PTT Timeout range from 0 minutes to 25.5 minutes. Typically this 

value is set between 1 and 3 minutes for practical applications.

When you are satisfied with all the settings that appear on the 

Module Configuration

 page, 

be sure to click on the button labeled 

Update Configuration

 at the top of the page. Your 

new settings take effect immediately. To revert back to the previously saved values while 

editing click the button labeled
