Broadcasting Live
8
Broadcast Live from a Microphone.
Set the Transmit Mode Switch on the Back Panel, to “Live Radio.” This immediately and automatically
selects the built-in microphone (located inside the unit and under the top panel grill) to act as the audio
source for the transmission.
Plugging in a hand held, high-Z microphone into the “MIC” jack on the rear panel automatically super-
sedes the built-in MIC and selects this MIC as the audio source for the transmission.
Note that the built-in audio limiter will keep the signal from distorting, but it is still best to speak directly
into the microphone and at normal and consistent volume for best sound quality.
Note that when using a microphone, the built-in speaker must be manually turned off or down via the rear-
panel ‘SPEAKER VOLUME” control to avoid feedback
Broadcast Live from a Studio or External Recorded Message.
Set the Transmit Mode Switch on the Back Panel, to “Live Radio” and plug a line-level signal (.1V to .5V,
unbalanced) into the “LINE INPUT” (1/8” mini phone) connector on the rear panel. This immediately and
automatically selects this external line input to act as the audio source for the transmission or recording.
Note that the built-in audio limiter will keep the signal from distorting, but it is still best to maintain the
incoming signal level at a consistent volume for best sound quality.
Note that when recording or broadcasting a LINE INPUT, the built-in speaker can be used to monitor the
broadcast signal or manually turned off or down via the rear-panel “SPEAKER VOLUME” control. The volume
level of the internal speaker will not effect the audio level of the broadcast signal.
Broadcast a prerecorded message from the internal “Message Chip” storage.
Set the Transmit Mode Switch on the back panel, to “Message Chip”. The transmitter will automatically
begin and continue to playback any audio recorded on the internal “Message Chip.”
Set the “Two-Part Message Select” switch in the “Part-1” position to playback only message one. Set the
“Two-Part Message Select” switch in the “Part-2” position to consecutively playback both messages parts
one and two.
