[1] P.A BLOCK Fuse-holder. Contains the protection fuse for the 3,15 A.power
supply
[2] R.F. OUTPUT RF Output connector N type, 50
Ω
.
[3] INTERLOCK BNC interlock connector: When the main conductor is grounded,
the transmitter is forced to go in stand-by mode.
[4] FWD EXT. AGC Trimmer for the control of the erogated power in function of the
FWD Fold input
[5] RFL EXT. AGC Trimmer for the control of the erogated power in function of the
RFL Fold input
[6] PHASE ADJ Trimmer for the regulation of the pilot tone phase.
[7] PREENPHASIS Dip-switch for the setting of the preenphasis 50 or 75
µ
s. 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.
[8] 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 50
Ω
or 10k
Ω
.
[9] SCA 1 BNC connector of the unbalanced SCA1 input.
[10] MPX/RDS BNC connector of the unbalanced MPX input.
[11] MPX/RDS ADJ Trimmer for the regulation of the levels of the MPX input.
[12] RIGHT/MONO ADJ Trimmer for the regulation of the levels of the Right input.
[13] RIGHT/MONO XLR connector for the input of the Right audio channel.
[14] PLUG AC voltage plug, 90-260V 50-60Hz.
[15] 24VDC IN Connectors for the external 24V supply . Positive (red)
or negative (black).
[16] FAN Blower for the forced cooling.
[17] R.F. TEST POINT -30dB output at the output power level.
[18] REMOTE DB15 connector for the telemetry of the device.
[19] EXT REF 10MHz Not used (reserved for future applications)
[20] RS232 DB9 connector for the interface with other equipment and
programmation made by the factory.

the synchronisation of the external devices such as RDS coder,
etc…
[22] SCA 2 BNC connector for the SCA2 input
[23] SCA2 ADJ Trimmer for the regulation of the SCA2 input levels.
[24] SCA1 ADJ Trimmer for the regulation of the SCA1 input levels.
[25] LEFT-MONO/MPX ADJ Trimmer for the regulation of the LEFT-MONO input levels.
[26] LEFT-MONO/MPX 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 600
Ω
or 10k
Ω
