EFM-100. The Amplifier, the RF output attenuation and the OSD video settings
are all handled via drop down lists, while pop-up windows are shown when
selecting the Tuner or the Modulator.
With the Amplifier enabled you can attenuate the RF out signal (Level) between
0 to -31dB in 1dB steps. NOTE! The RF attenuator is always enabled.
. The Tuner can be enabled or disabled. When enabled, the audio connectors act
as outputs. The frequency of the Tuner can be adjusted between 76 and 108 MHz
in 0 kHz steps. If needed the Tuner can be set to Mono mode. Make your
choice and click [ OK ].
6. The Modulator can be enabled or disabled and if enabled the output frequency
can be adjusted between 76 and 108 MHz in 0 kHz steps. The output level can
be adjusted from 0dB to -6dB in four steps. NOTE! As shown in the Block
schematic (see page 11) the Modulator output level is also affected by the RF
output attenuator.

7. The video OSD output (On Screen Display) can be set to indicate “P1” to
“P7” in the upper right corner on TV sets connected via an RF modulator (as
the EVA-200 or EVA-210). If you select “Black” the screen will be blank. This
function can be used when the EFM-100 is installed in a hotel system. The

and the installation is ready.
It is possible to change from Stereo to Mono Mode if wanted. You can also
attenuate the incoming LF signal (from phono left and right) by 9dB if
necessary. The RDS Name box allows you to send your own RDS info with up
to 8 letters. Leaving the RDS Name field blank disable the RDS transmission.
The preemphasis is setted to 7 µsec as default but can be changed to 0 µsec
or can be set to Disabled. NOTE! 7 µsec shall be used for all normal purposes.
