GENERAL DESCRIPTION ENG
Page 27
1 ON/OFF Switch: main ON/OFF switch, the LED inside switches on/off accordingly. The power supply socket (use
the cord provided) has a built-in fuse drawer containing the power fuse and a spare, both of the same value: for
230 V AC the fuse is rated at 500 mA T; for 110 V AC it is rated at 630 mA T
2 RS232 Serial Port 2: This port is intended for the processor setting and programming from satellite and
unidirectional
links. Supported Baud Rate: 4800.
3 Digital audio output*: This has two connectors: use the XLR for balanced coaxial connections and the tos-link for
optical connections. It provides Aes/Ebu and Spdif signals @ 48 KHz, 24 bit.
4 Digital audio input*: This has two connectors: use the XLR for balanced coaxial connections and the tos-link for
optical connections. It accepts Aes/Ebu and Spdif signals at different sampling rates
5 Sync-out*: 19KHz synchronism output at 5Vpp, to lock external equipment (such as RDS coders). It is disabled by
default and must be enabled by the menu.
6 SPLIT ON Led*: it lights on while the Split command is active (and thus the OUT 2 is on Split)
7 MPX OUT 2*: additional MPX output, driven by a special circuit ( ‘SPLIT’). It is disabled by default. Preemphasis
can NOT be removed from this MPX output
8 MPX OUT 1*: main MPX output. The trimmer near the Bnc connector tunes the MPX output level between -inf and
+12 dbu (factory preset is 0dbu). Accordingly to the current configuration, the output BNC connector will include
the composite / MPX program signal with the RDS / SCA subcarrier mixed into and with or without signals injected
from AUX inputs. An hardware bypass directly connect the AUX1 input to OUT1 in the event of power failure or
processor switched off. Preemphasis can NOT be removed from this MPX output
9 MPX OUT 1 TEST*: provides a repetition of the output signal appearing at the main MPX OUT 1 connector, with
the same level
. It may serve for measurement or as secondary MPX output. Preemphasis can NOT be removed
from this MPX output
10
AUX 1 Input*: Bnc female connector. Depending on the MPX board configuration, it allow the injection of
RDS/SCA or MPX signals from external encoders/generators. The resultant signal is available on the Output
connectors OUT 1 or OUT 2. Factory preset: 0dB gain.
11
AUX 2 input*: Bnc female connector. Depending on the MPX board configuration, it allow the injection of
RDS/SCA or MPX signals from external encoders/generators. The resultant signal is available on the Output
connectors OUT 1 or OUT 2. Factory preset: 0dB gain.
12 ANALOG AUDIO OUTPUT: It provides the L and R processed audio signals on which it is possible to
enable/disable pre-emphasis. The level is set via menu.
13 ANALOG AUDIO INPUT: bi-channel audio input electronically balanced on XLR female. The input level is set via
menu. An hardware bypass directly connect the two input XLRs to the output ones in the event of power failure or
processor switched off.
14
RS232 SERIAL PORT 1: This port is intended for the processor setting and programming by means of the
supplied Pc control software application (bidirectional connection). Supported Baud Rate: 19200.
15
OPTO INPUT PORT*: SubD 9-pin female Interface. It supports 2 optoinsulated “trigger” inputs (for TA flag toggle
and for SPLIT mode enabling)
16
RELAY OUTPUT*: Reserved for future use
* available as an option
