CC450-0V2 Communications Controller
Installation and Operation Manual
3.3.3.3
BOTH Mode
With the Mode switch in the centre position the CC450-0V2 is in the BOTH mode
In BOTH mode, RELAY and SIMULCAST modes are combined, with priority given to SIMULCAST mode.
The received audio signal from any selected transceiver is transmitted (relayed) out on the other selected
transceiver(s).
Microphone audio is transmitted out on the transceiver as selected by the Audio Controller. If that
transceiver is selected by the transceiver switches on the CC450-0V2, then the microphone audio is
transmitted (simulcast) on all selected transceivers.
If a microphone is keyed on a selected transceiver and a relay is in progress, the relay is cancelled and
the microphone audio is transmitted (simulcast) on all selected transceivers.
3.4 Alert Tones
Alert Tones are generated to indicate that the CC450-0V2 is Relaying or Simulcasting signals. During
Simulcast, an alert tone is generated at the beginning of the transmission to notify the operator that his
signal will be simulcast. During Relay, an alert tone is produced at the beginning of the transmission to
notify receiver operators that they are receiving a relayed transmission. When the relay is over, an alert
tone is transmitted out on all selected transceivers to notify the receiver operators of the end of the
relayed transmission and the transmitter operator that the transmission was relayed.
3.5 Voice Store and Retransmit (VSR) [OPTIONAL]
The CC450-0V2 has the ability to store up to 60 seconds of receive audio signal from a transceiver and
Retransmit that signal on the same transceiver.
To set up the CC450-0V2 for VSR operation, the mode switch must be in the RELAY position and only
one transceiver selected as active.
Up to 60 seconds of receive audio signal from the selected transceiver will be stored. If the receive audio
signal is longer than 60 seconds, then only the first 60 seconds will be stored. When the receive activity
is ended, the CC450-0V2 will transmit the stored signal out on the transceiver selected as active.
Note: In earlier versions (CC450-xV1 models) this storage time was 16 seconds.
