2 Display Function
The menus available in the current software version are:
- Mpx Encoder
- Rds Encoder
- Changeover
- System
Once you have selected the menu to access the submenus where you want to edit the parameters, just
press the edit / enter key
2.1 Station ID
On the main page along with the name of the various menus to the left of the "<" symbol, a user-definable
label is shown on the bottom line to identify the repeater to which the device is assigned.
The text shown will not be sent to any RDS block, since it is only a reference for the user.
2.2 Mpx Encoder
The first available menu is Mpx Encoder, once the edit / enter key is pressed you access the submenu
parameters.
2.2.1 Audio Levels
In the first submenu of the Mpx Encoder, the MPX output level is indicated.
The subsequent displays show the input levels of the left / right channels, with a graduated scale in dB in
one and both channels in the other.
The input level can be adjusted by 0.5dB steps through the next menu by using the "In Gain" parameter or,
finely, using the trimmers on the rear panel next to the audio input connectors (TRIMs).
A 0dB input level on both channels will produce a total deviation relative to the audio only, excluding the
pilot carrier and the RDS signal, of about 67KHz.
By adding these two components, you will achieve the 75KHz total deviation.
