ADA102mpx. If you don't have a
modulation meter, do not change this
preset.
Do not push the screwdriver. The preset can be broken.
The level knob at the ADA102mpx front panel do not
changes the MPX level. Only take effect on the level of
balanced outputs, so it must be adjusted only to obtain
a visualization at the VU-meters, which will indicate
that
input streaming is present
.
The internal input gain (software) do not be
changed. It must be -1 dB (default value).
1.4.2.2 Full digital connections
Whenever the audio processor is located, in a full
digital audio chain
– case (b) mentioned above –
the
controls on frontal panel do not take effect over the
signal. The adjustment is made from web control
panel. The level of the digital audio is not changed
by the encoding–decoding process.
•
You must set the output level of the decoder
output (wich excites the stereo coder input)
according to the output level (dBfs) of the
audio processor. Default output level is -1 dB
(for use with analog signals).
This level is adjusted from web control
pannel, in the section
Basic Settings →
Configration → Audio
(Output Audio Level)
.
Next, a table with reference Output Audio
Level values.
Procesador output
(dBfs )
Decoder Output
- 3 dBfs
- 6 dB *
- 6 dBfs
- 3 dB
- 9 dBfs
0 dBfs
* Value for Solidyne digital processors
The knob level at the front panel only takes effect over
analog inputs, and the VU meters do not operate with
digital signal.
•
To adjust the modulation depth, proceed
like the previous case (MPX preset).
1.4.2.3 Audio processor locates at
transmission plant
When ADA102 links the Studios to Transmission
Plant, where ADA102 DECODER connects to the
audio processor; the audio level managed by
ADA102 link
is not critical,
since the processor at
the end of chain controls the level sent to the
transmitter.
•
In ADA102 CODER, adjust the input gain
to reach 0 VU with signal peaks. If you are
connecting the AES-3 input, the level
adjustment is no needed (neither possible).
•
In ADA102 DECODER, adjust the output
level knob to reach 0 VU with signal peaks.
If you are connecting the AES-3 output, the
level adjustment is no needed (neither
possible).
•
Now follow the Audio Processor user's
manual in order to adjust the modulation.
1.4.3 Using an RF digital link
The use of a ADA102 CODER in studios connected
to broadband Internet, allows to cover any distance
from studios to transmitter plant. This solution can be
used to STL links and for radio networks, so one
coder from studios can send a signal to several
slaves throughout the country.
Another solution to transport the audio streaming
maintaining the great sound quality at low cost: a
microwave link
for 5.8 GHz (or 2,4 GHz in some
countries) using the standard 802.11.x. This
band is
free
in all countries and does not require any special
authorization. It is able to cover 45 Km and should
not have major obstacles between the two sides.
