Below you find description of the different settings in the main menu. See Block Schematic in next page
1. VIDEO OSD ( TV OSD )
If you connect the Video connector of the EFM-100 to an RF modulator or direct to a
TV set, you can here choose if you want to put a text (
P1
to
P7
) in the signal that will
appear on connected TV sets in the right upper corner of the TV picture or select
“Black” for a blank screen. (For instance when EFM-100 is installed in a hotel system).
2. FM TUNER
Set this to ON (click in the box) to activate the FM tuner. This give you the opportunity
to remodulate the received signal to a different output frequency using the FM
Modulator. You can also use the demodulated LF on the R and L audio connectors for
connection to a RF modulator ( for example EVA-200 or EVA-210). Click in the
frequency box and enter a frequency between 76 and 108 MHz (can be selected in 50 kHz
steps). Click on
[ Program Frequency]
to make the settings to take effect. You can also
select Mono mode instead of Stereo mode if wanted.
3. FM AMPLIFIER
If you set this to ON (click in the box) the EFM-100 will amplify all signals between
76 and 108 MHz that is received from the FM antenna input.
4. FM MODULATOR
With this function set to ON you can choose output frequency either from a signal
source connected to the R and L audio connectors or choose a different frequency for a
FM signal from the FM Tuner. Click in the frequency box and enter a frequency between
76 and 108 MHz (can be selected in 50 kHz steps). If you connect an external audio
source you can attenuate the incoming signal by 9 dB (Audio Sensitivity).
Preemphasis is possible to change from 75 µsec to 50 µsec or Disable.
NOTE!
75 µsec
shall be used for all normal purposes. If needed you can also choose Mono Mode. In the
box for RDS Programme service you can enter up to 8 letters. If you do that you have to
click on
[ Program RDS ]
to enable the settings. Always press
[Program Frequency]
to
make the settings to take effect
5. RF OUTPUT LEVEL
This gives you the possibility to attenuate output signal from FM Modulator ( 0 to -6dB ).
6. RF OUTPUT ATTENUATOR
Click on this drop list and you can attenuate the output level from EFM-100 between 0
and -31dB in 1dB steps. This function is always enabled.
