[1] PLUG & FUSE BLOCK VDE plug for AC voltage and fuse-holder. Contains the
protection fuse for the 3,15 A.power supply.
[2] FAN Blower for the forced cooling.
[3] R.F.OUTPUT  RFOutputconnectorNtype,50Ω.
[4] PHASE ADJ Trimmer for the regulation of the pilot tone phase.
[5] PILOT LVL Trimmer for the fine regulation of the pilot level.
[6] MODE/MPX IMP Dip-switch for the selection both of the transmission mode
(STEREO or MONO) and the impedance of the MPX input
MPX,selectableat50Ωor10kΩ.
[7] SCA 1/RDS BNC connector of the unbalanced SCA 1/RDS input..
[8] MPX BNC connector of the unbalanced MPX input.
[9] MPX ADJ Trimmer for the regulation of the levels of the MPX input..
[10] SCA 1/RDS ADJ Trimmer for the regulation of the SCA 1/RDS input levels.
[11] RIGHT ADJ Trimmer for the regulation of the levels of the Right input.
[12] RIGHT XLR connector for the input of the Right audio channel.
[13] TOSLINK Not used.
[14] ADJ R Not used.
[15] ADJ L Not used.
[16] SLOT Not used.
[17] SERVICE/RDS DB9 connector for the programmation made by the factory.
[18] 24VDC IN Not used.
[19] R.F. TEST POINT Maximum 20dBm output at the output power level.
[20] CARRIER FREQ. ADJ Trimmer for the fine regulation of the carrier frequency.
[21]PREENPHASIS Dip-switchforthesettingofthepreenphasis50or75μs.
The preenphasis has an influence on the right and left inputs
in stereo and on the mono input. The MPX inputs are not
influenced by the setting of the preenphasis.
[22] 19KHZ PILOT OUT BNC output connector for the pilot tone, which can be used
for the synchronisation of the external devices such as RDS
coder, etc...
[23] SCA 2 BNC connector for the SCA2 input.
[24] SCA2 ADJ Trimmer for the regulation of the SCA2 input levels.
[25] LEFT/MONO ADJ Trimmer for the regulation of the LEFT/MONO input levels.
[26] LEFT/MONO XLR connector for the LEFT/MONO audio channel input.
[27] IMPEDANCE Dip-switch for the selection of the impedance of the balanced
audioinputs,selectableat600Ωor10kΩ.
[28] AES/EBU Not used.
[29] INTERLOCK IN BNC interlock connector: When the main conductor is
grounded, the transmitter is forced to go in stand-by mode.
[30] RFL EXT. AGC Trimmer for the control of the erogated power in function of
the RFL Fold input.
[31] FWD EXT. AGC Trimmer for the control of the erogated power in function of
the FWD Fold input.
