Channel Selection - Monacor AV-3040TX Mode D'emploi

3) If the receiver used is provided with a control
channel, it is possible to activate an optical or
acoustic signal device or another additional unit
connected to the receiver via this channel (e. g.
video recorder for automatic start of a recording).
On the transmitter, the control channel is activated
by short-circuiting the terminals (6). Connect e. g.
a motion detector with NO (normally open) contact
to these terminals.
For testing the control channel after setting the
transmitter into operation, actuate the button "test
switch" (3). As long as the button is actuated, a
control signal is transmitted which will activate the
unit connected to the control output of the receiver.
4) For power supply, a regulated power supply unit
with an output voltage between 7 V
and an output current of at least 150 mA is re-
quired, e. g. MONACOR PS-500ST. In case of
power supply units with variable output voltage,
adjust a value between 7 V and 30 V. Connect the
power supply unit via a low voltage plug 5.5/
2.1 mm (outside/inside diameter) to the jack "DC
7-30 V" (9). Always observe the correct polarity:
connect the positive pole to the inner contact of the
plug. After the supply voltage has been applied,
the transmitter is ready for operation and the chan-
nel display (1) lights up.
4.3 Adjustments

4.3.1 Channel selection

The wireless transmission is made in the 2.4 GHz
range which has been divided by the manufacturer
into five channels with a distance of 14 MHz. As a
maximum, three channels can be used simulta-
neously (channels 1, 3, and 5) as two adjacent chan-
nels will interfere with each other. The following chan-
nel selection is recommended:
for two transmitters:
for three transmitters: channels 1, 3, and 5
Adjust the transmission channel with the button
"channel selection" (2). The selected channel will then
appear on the channel display (1).
4.3.2 Adjusting the audio level
The input sensitivity of the inputs "audio A in" and
"audio B in" (8) can be adjusted from 500 mV to 10 V
with the control "audio level" (4). The audio signal at
the receiver or the monitor must neither be distorted
(in this case turn back the control correspondingly)
nor noisy (in this case advance the control cor-
respondingly).
