1.2 System Concept
1.2.1 General
The INCA TXF-RC is a series of wireless audio, remote controllable,
small sized VHF transmitters intended for concealed room monitoring or
as body transmitters.
The TX unit comes with flying leads for the battery connection and the
antenna terminal has a female MMCX-connector. The TX unit is
deliverable with either
internal or external microphone.
Note:
The special functions / upcodes will only be available, if using an
X-IDER TX. Please refer to Section 1.2.7
Remote Control Upcodes –
TXF-RC VHF .
1.2.2 Different settings
Sleep mode on / off:
The transmitters can be switched into sleep-
mode. In sleep-mode, the current consumption is only app. 100 uA,
which maximizes the lifetime of the battery more than 1000 times.
In sleep-mode the receiver only goes on the air in app. 30 msec. for
every 2.5 seconds to look for a valid code transmission
VOX mode on / off:
At the expense of a little higher current
consumption (app. 150 uA), the transmitter can be switched into VOX-
mode, meaning that the transmitter will run only when the microphone
hear acoustic signals like talking or music. This VOX is an advanced
type of circuit that has the ability to distinguish voice from background
noise and the power circuit is only switched on when a voice signal is
present. Therefore, the switching operation is highly reliable in noisy
environments.
AGC on / off:
is integrated in the transmitter. The AGC action prevents
over-modulation at high sound levels and makes it possible to listen to
very weak conversation at the same time.
Scrambler on / off
: The transmitter includes an audio scrambler-circuit,
which can be switched on and off by the remote control.
