1.3 eatures
The encoder/decoder Solidyne ADA102 is a stand
alone streaming generator, designed to work as Studio
to Transmitter Link (STL). Encoder works with stereo
audio signals turning it into an MP3 or PCM audio
streaming, under different modes (see specifications).
The coded output is an RJ45 connector compatible
with Ethernet TCP/IP networks. ADA102 has
analogical audio inputs (balanced) and digital AES-3 or
S/PDIF.
At the other end, an ADA102 set as DECODER
convert the incoming stream (from Internet or
microwave link 802.11.x) into analogue audio signal or
a digital stereo AES-3 (S/PDIF compatible), sent to
transmitter.
Model ADA102mpx decoder incorporates a third type
of output: aseband MPX for direct connection to a
broadcasting FM transmitter.
The unit has four relay remotely managed. At the
encoder, four inputs manages four switches on the
decoder, and vice versa.
The USB port lets you connect a pendrive when the
ADA102 works as a decoder. If the incoming streaming
drops, the ADA102 Decoder will start to play audio files
from US device until the connection restored.
The serial port support "gateway". From studios,
using a computer connected to the ADA102 encoder,
you can command a remote device directly connected
to the ADA102 decoder at the transmitter plant, as if
the device was connected directly to the computer on
Studio.
Main features
•Can be set as Encoder or Decoder by
settings using the WEB Control Panel.
•Generates MP3 streams at adjustable bit
rates (VBR) from analogue or digital (AES-3)
sources. Compressed audio is not supported

Section 1 Hardware and connections
1.1 General connection diagram
1.2 Rear panel
1.2.1 Power supply
Always CHECK the correct position of the
VOLTAGE SELECTOR (2 /24 V o 1 /13 V,
according to the country)
AC wires do not have to be mixed with audio wires,
especially with analogical ones. Remember that all
audio installation must have a trustworthy grounding.
We recommend accomplishing with the standards -
Article 810 of the National Electricity Code (NEC);
ANSI/NFPA Nº 70-1984 in USA; IRAM 2379 and
2281-3 in Argentina. This standard provides
information and guidelines for a consistent grounding.
1.2.2 Audio inputs and outputs
Analog inputs and outputs are electronically
balanced. The inputs are “bridging” type, with
impedance greater than 10 KOhms. The connectors
used, as is standard, are female XLR-3 for the inputs
and male for the outputs. Take specially care with
the phase.
Use one pair shielded audio cables of good
quality, preferably with double shielding. The
maximum length recommended is 30 mts,
although in special cases it's possible to
achieve 100 mts. accepting a little loss at high
frequencies.
The connection of this cables are made as is
standard. See the following table:
Balanced input/output connections:
1 = GND
2 = balanced positive phase (+)
3 = balanced negative phase (-)
Unbalanced connections:
Inputs: Signal = 2; GND = join 1 y 3
Outputs: Signal to pin 2; leave pin-3 unconnected. GND = pin 1
AES-3 input and output cables connect as following:
XLR Signal
1 GND
2 AES3 (1)
3 AES3 (2)
AES3 standard connection

S/PDIF device can connect to AES-3 input/output of
ADA102 using an S/PDIF to AES-3 adapter.
No software setting is needed to enable AES-3. Decoded
audio are always sent to Analog and AES-3 outputs.
1.2.3 LAN port
Standard Ethernet RJ45 10/100 to connect the unit to
a switch/router to send or receive audio streaming.
1.2.4 USB port
Lets plug in a flash memory storage (Pen Drive)
when the unit works as a decoder, so that in case of
loss of streaming, the decoder switches to the Pen
Drive to continue with the audio playback. US 1.1
compatible devices are supported, with the following
limitations:
•Only mass storage devices are supported.
•HUB's are not supported (some flash drives have an internal
HUB)
•4GB is the maximum capacity. If the flash disk is larger, create
a 4 GB partition. Only the first partition is supported.
•First partition mus be AT16 format.
If your computer does not recognize the pen drive,
the following procedure can help you find the reason:
•Open an Internet browser, enter the ADA1 2 IP address
followed by /status (i.e.: 1 2.168. .11 /status).
•Scroll down until "USB device info"
•Check if "Filesystem type” is "FAT16". If it's "FAT32", reformat
the USB memory as FAT16.
The US must contain a playlist file named
"playlist.m3u" which determines the order in which
MP3 files are played.
When the USB is plugged, ADA1 2 will reboot to detect
the device, so audio output will be muted by few seconds.
1.2.5 Serial port
The serial port is used to command, from the studios,
a device located in the transmitter plant as if it were
directly connected to serial port of the computer at
the Studio. For this ADA102 generates a gateway for
transporting serial data transparently through the
network (see "2.3 - Advanced Settings). The
connection requires a standard RS232 cables.
1.2.6 Remote control
Each unit has four inputs and four outputs for
remote control. Each input can controls a switch off
the remote unit.
Inputs are type “dry inputs”. To enable an input
(input “on”) send it to a GND pin of D -15.
The output switches 1 and 2 are "open collector"
type (used for example to command external control
circuit). Switches 3 and 4 are mechanical relays that
can manage up to 1 A @ 24 VDC.
D -15 pin out:
PIN Signal PIN Signal
1Input 1 5Switch 1 (open collector)
2Input 2 6Switch 2 (open collector)
3Input 3 7 y 14 Switch 3 Relay, normal open
4Input 4 8 y 15 Switch 4 Relay, normal open
9 a 13 GND
1.2.7 MPX output (optional
ADA102mpx)
The model ADA102mpx includes a stereo coder
that generates the FM baseband signal. This output
is connected to an FM transmitter. The MPX cable
is a RG-59 (coaxial 75 ohms), like the used for
CATV. The output connector is NC. The maximum
length recommended for this cable is 25 m. Take
care with the grounding; although this rarely is
cause of problems because all Solidyne processors
have MPX differential outputs, that is to say, with the
ground isolated from the cabinet, to avoid ground
loops. If some residual humming appears when the
system is on the air; power off ADA102. If the
humming disappears, check the input connections
at the decoder. If, however, the humming continues
(and only disappears unplugging the MPX cable),
this indicates some important problem with the
grounding.
When enters to the transmitter through the MPX
input, make sure that the internal pre-emphasis
network IS DISCONNECTED (that is to say, flat
response from 20 Hz to 100 KHz). Contrary, when
use an external stereo coder, make sure that the
generator INCLUDES the pre-emphasis curve. This
is due that ADA102 audio output DOES NOT
INCLUDE pre-emphasis (only the MPX output has
pre-emphasis).
1.2.8 Reset
Pressing this button restarts the unit. Press and hold
for 10 seconds to reload the factory defaults.
If you start your computer holding down the button
for 5 seconds, ADA102 starts in “firmware update”
mode.

1.3 rontal panel
1.3.1 Level indicators
ADA102 has two needle-type VU meters that shows
the real peak value of audio signal.
1.3.1.1 VU mode Tx/Rx
This button changes the signal that the VU shows.
Tx shows the level of the analogue input. Adjusting
the input level you are adjusting the transmission
level. This is the usual work mode in the Studios.
Rx shows the output level of analogue output and
streaming. This is the usual work mode in the
Transmitter Plant.
Level indicators do not work with AES-3 signals.
1.3.2 SATUS LED's
During the initial boot up sequence the 2 status indicator
LEDs can indicate the following anomalies:
No Application loaded (only bootloader) or started
with hold reset button during power up: The green
LED is on and the red LED blinks.
Application starts (boot-up sequence):
First the red goes on and the green LED blinks once.
Then during the startup the green and red LEDs
blink.
During DHCP the red LED blinks with a continuous
cycle . The green LED blinks five times and then
pause four times.
If an error is detected the red led remains on and the
device resets itself after the green LED has indicated
the error as follows:
ERROR Green LED blinks
Corrupt application or IP address conflict five times
The Network hardware could not be initialized
or a Corrupt MAC address three times
In normal conditions:
Green LED Red LED State
OFF BLINKING
Application is detecting USB devices or
announcing the assigned IP address
using SonicIP technology.
ON OFF The application is operational.
ON ON Reset Button is being pressed, the unit
will reboot after releasing the button.
1.3.3 Headphones output
Gives the output signal with headphones level, to
monitoring. The level changes with the output level
control.
1.3.4 Input Gain
Manages the input gain of the analog inputs. Adjust this
level to reach 0 VU with signal peaks. To see the input
level the VU meter must be in Tx mode.
1.3.5 Output Gain
Manages the analog output level. At 0 VU the output
level is +4 d m. To see the output level the VU meter
must be settled as Rx from rear panel.

1.4 STL connection diagram
1.4.1 Connection diagrams for
streaming transport
The figures above shows two examples of
streaming link in FM stations.
In diagram (a) the audio processor is located at the
studies, and carries the processed audio to a
ADA102mpx connected directly to transmitter. In this
way the processor works with the audio signal
directly from the console, and ADA102 carries the
processed audio. This is the recommended
configuration for FM.
The diagram (b) shows a chain of 100% digital audio,
using inputs and outputs AES-3. In this case, the
processor appears in transmission plant, which is
processing the audio decoding of MPEG streaming.
The output of MPX audio processor is connected
directly to the transmitter.
In AM stations, the audio processor must be close
to the transmitter to maintain a DC coupling that
allows the asymmetric modulation.
Figure (a) – STL with audio processor at the Studios
Fig.(b) – STL using an digital audio chain. For AM stations, the audio processor must be next to the transmitter
1.4.2 Set the audio levels
1.4.2.1 Audio processor locates at the
studios with analogical connections
When the audio processor is at the Studio,
connected by analog input – case (a) mentioned
above – the input level of ADA102 CODER is a
critical issue.
•Choose a high density musical program.
•Play on-air the music and check the audio
processor to verify that the AGC compression
be 10 d or higher.
•Adjust carefully the ADA102 input gain to
obtain a 0 VU deviation with the peaks.
Needle must never overpass the 0 VU
indication.
At the other end, ADA102mpx receives the
streaming. The incoming streaming is decoded and
sent to MPX stage. To adjust the 100 % of
modulation proceed:
•ADA102mpx has two presets at the rear
panel: MPX level and 19 kHz Pilot Tone
level.
•Playing the same high-density song used
to adjust the CODER, adjust the MPX level
preset to obtain 100% of modulation at the
transmitter. Read this value at the exciter
VUmeter
•If you have a modulation meter available
(Solidyne VA16, elar, Innovonics, etc.) we
recommends to use the measurements of
this instrument instead of the exciter value.
•If you have a modulation meter available,
adjust the pilot tone depth to 8% / 10%
using the correspondent preset of
SOLIDYNE ADA102 CODER/DECODER Page 8

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 d (default value).
1.4.2.2 ull 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 (d fs) of the
audio processor. Default output level is -1 d
(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 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 R 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.
