Stereo Input Board
The optional boards offer extra facilities required by customers and are simply
fitted by inserting them into the relevant slots, described on page 7 of this manual, with
the unit switched off.
This board comprises two
modules:
- Inputs
- Clipper
Inserted into the slot indicated
on page 7, it has the function
of processing the audio signal
for stereophonic transmission.
The board also supplies the
processed stereo signal to the
microcontroller which displays
stereo levels using a bar graph
and values expressed in dBu.
The input connectors are balan-
ced, XLR type (see the connec-
tion diagram below).
Adjustments:
 selection (jumper) of the value of pre-emphasis (50/75 usec)
 ON/OFF (jumper) of pre-emaphasis
 ON/OFF (software) of pre-emphasis, of the clipper and of the filter
 adjustment (software) of the level in steps of 0.5dB on each channel
 selection (jumper) of the input impedance value (600Ohm/10KOhm)
