AM360r User Manual
revised 2014.02.29 for
Hardware Rev. DD
Firmware Version 1.00.26
Transmit Pre-Emphasis Enable
(default cleared) will apply a 6 dB per octave high pass filter
to the transmit audio stream from the IP network to the transmitter audio of the attached
radio. Check the box to apply this filter or clear the check box to allow the transmitted
audio to pass unprocessed (flat audio). In general, if the transmit audio line of the
AudioMate 360r is connected to the microphone input of the attached radio, then leave
this check box cleared. If the audio is fed directly to the FM modulator of the radio, this
check box should be checked to enable pre-emphasis.
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. The default
value is 31.
PTT Forced Release Timeout
prevents the attached radio from tying up the channel, such
as a stuck footswitch on a console on the IP network. The timer starts when the radio PTT
is asserted. If the timer expires during a transmission, the transmitter will be released.
Acceptable values for
PTT Forced Release Timeout
range from 0 to 25.5 minutes. Typically
this value is set between 1 and 3 minutes for practical LMR applications. Default is 0 which
disables this timer.
PTT Release Hang Timer
sets the time period between the end of the inbound 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 Release Hang Timer
range from 0 to 25.5 seconds in increments of 0.1 seconds.
Default is 0 which disables this timer.
PTT Anti-Chirp Timer
mutes the radio receive line for the specified time beginning
immediately after PTT is released. Because some inferior radios generate a burst of noise
immediately after unkeying, this “chirp” can cause a ping-pong effect when two similar
radios are used on both ends of a VOX link. Setting this timer between 0.5 and 1.0 seconds
can suppress this problem in an AudioMate point-to-point bridge when both ends use VOX
mode. Default is 0 which disables this timer.
