Introduction
Congratulations on your purchase of this Solid State Logic XLogic SDI-MADI unit. Please be assured that it will provide
you with many years of reliable service while delivering the pristine audio quality you expect from any Solid State Logic
product.
The SSL SDI-MADI is a cost-effective solution to the problem of connecting audio equipment to the SDI-based
infrastructure found in many broadcast facilities today. Occupying only 1U of rack space, the SDI-MADI provides the
interface between SDI video bit streams and digital audio. SDI-MADI extracts up to 16 audio channels from each of the
unit’s four SDI inputs to provide a total of up to 64 audio channels in both MADI (AES10id-2008) and AES3 (AES3-1992)
formats. All SDI inputs independently auto-sense between 3G, HD and SD standards and are provided with loopthrough connectivity for downstream equipment.
With a comprehensive range of synchronising options and switchable sample rate convertors, the SDI-MADI is designed
to reliably
and seamlessly integrate into any broadcast environment where SDI-embedded audio channels require format
conversion.
This manual covers the XLogic SDI-MADI’s connections and indications, including its various options for
synchronisation and external control. Please keep the manual in a safe place once you have installed the XLogic SDIMADI unit.

The XLogic SDI-MADI is built in a 1U 19” enclosure. It is intended to be permanently installed in a standard 19” equipment rack. The unit has no
internal fans and is cooled by natural convection. There are ventilation grilles in the top, bottom and both sides of the enclosure, and care must
be taken to ensure that these are not blocked by cables or other equipment when the unit is installed. Do not install any other items of
equipment immediately above or below to the SDI-MADI; the use of 1U blanking panels is recommended.
Power Supply Considerations
Power Supply Considerations
Power Supply ConsiderationsPower Supply Considerations
The SDI-MADI is fitted with two separate, auto-ranging switch-mode power supplies (PSUs). The operating voltage range is 90 to 264 V AC,
50/60 Hz. The internal power rails are diode-paralleled to the two supplies, and the unit will operate normally if only one PSU is powered or
functional. For maximum protection when using both PSUs, the two AC inlet cables should be connected to mains circuits which are as
independent of each other as possible. If redundant operation is not required, only one AC supply cable need be connected; either AC inlet may
be used.
Fuses And Ratings
Fuses And Ratings
Fuses And RatingsFuses And Ratings
Each of the SDI-MADI’s PSUs has an internal resettable fuse for PSU protection. These fuses are no accessible to the user. The unit should be
powered from a mains supply (supplies) fitted with an external HRC-type fuse (High Inrush Current) rated at 1 A.

The SDI-MADI can simultaneously de-embed the 16 audio channels in each of four separate SD video signals. Four BNC sockets are provided a
the rear panel for connecting the SDI inputs. The characteristic impedance is 75Ω . The SDI-MADI is compatible with all SDI formats up to 3G
(2.9 Gbps and auto-detects between them. See the Technical Specifications on page 16 for full list of compatible
formats.
Each SDI input has an active “loop through” output to simplify the connection of further equipment. The outputs are fully buffered from the
inputs and are re clocked. The SDI bit stream is otherwise unaltered.

Each AES3 output carries 2 audio channels, thus the 16 audio channels embedded in each SDI input generate 8 AES3 outputs.
To aid installation, an optional AES Signal Break Out accessory (ASBO) is available from SSL. This consists of a 1U 19” panel with 32 BNC
sockets, prewired to a 37-way Dsub plug. This may be mounted at the front or rear of the rack and greatly simplifies wiring.

The 64 de-embedded audio channels are also available as MADI (Multichannel Audio Digital Interface), in both co-axial and optical formats.
The MADI bit stream contains all 16 channels from all four SDI inputs. The channel numbering within the MADI bit stream is one-to-one, i.e.,
Channel 1 of SDI 1 becomes MADI Channel 1, Channel 2 of SDI 1 becomes MADI Channel 2, and so on for the remainder of SDI 1’s audio
channels. Then Channel 1 of SDI 2 becomes MADI Channel 17, and the cycle repeats. If less than four SDI inputs are in use, the
MADI bit stream time slots corresponding to the unused inputs will simply contain all zeroes.
The co-axial MADI output is on a BNC socket, and is compliant with AES10id-
2008. The characteristic impedance is 75Ω, at a nominal data rate of 125Mbps.
Transmission distances up to 50 m are generally achievable.
The same bit stream is available in optical format on an ST type connector,
allowing the MADI output signal to be transmitted by fibre if preferred.
Recommended fibre types are 62.5/125 µm or 50/125 µm, multimode.
Transmission distances of at least 1000 m are achievable.

The sampling frequency of the audio data embedded in SDI video signals is 48 kHz. This is invariant, and is enshrined in the defining
standards for all SDI formats. As with all operations involving digital audio, it will generally be desirable for the audio outputs of the SDI-MADI
to be synchronised (in frequency and/or phase) with a master reference clock, which will also synchronise all other digital audio processing in
the facility.
To achieve this, the SDI-MADI includes four 16-channel Sample Rate Converters (SRCs), one for each SDI input (see Rear Panel Description on
page 8). Each SRC may be switched in or out by a front panel switch (see Front Panel Description on page 7) or by external control via the GPIO
port. When each SRC is active, a red LED illuminates, and a tally output voltage is also available at the rear GPIO port. When enabled, the SRCs
re-clock the audio data against a new reference, thereby changing the sampling frequency of the data to that of the reference. They also ensure
that the word blocks in the data are phase-locked exactly to the reference clock. The SDI-MADI allows the user to select a reference clock source
to suit the infrastructure of the facility and the nature of the transfer process.
See following section on “Synchronisation”
GPIO Control
GPIO Control
GPIO ControlGPIO Control
As the SDI-MADI could be installed in a central control room or outside broadcast vehicle using automated system software applications,
external control of the SRCs can be achieved via the GPIO port. Simple contact closure (grounding the GPI) enables any or all the SRCs, allowing
them to be switched in or out from a remote point. Maximum recommended operating distance is 5 m (though this may be increased by the use
of external relays or similar).
Refer to the pinout on page 12 for wiring details.
Synchronisation
Synchronisation
SynchronisationSynchronisation
The SDI-MADI offers a choice of wordclock synchronisation sources. The selection is made from the front panel, and the array of LEDs confirms
the currently-selected source. The selected source is used as reference for all four output SRCs, thus ALL audio outputs, both in AES3 and MADI
formats, will be locked to the selected reference. The various clock sources are discussed on the following page.

Synchronisation

Sync To WordclockSync To Wordclock
SRC sync to an external wordclock is indicated by illumination of the ‘WK’ front panel LED. The clock source should be connected to the SYNC IN
connector (a BNC socket) on the rear panel. Nominal frequency is 48 kHz 50ppm, and clock pulses should be of 5 V amplitude, positive-going.

The SDI-MADI can also synchronise to a standard (SD) 1 V black-and-burst video signal. The video signal should be connected to the SYNC IN
connector on the rear panel. The sync input auto-detects NTSC or PAL standard video.
Sync To AES3

Sync To AES3Sync To AES3
An AES3-compliant digital audio source may be used as the clock reference source. The internal 48 kHz wordclock source is phase-locked to the
incoming AES3 signal. Any audio data contained in the AES3 word will be ignored. The audio source should be compliant with AES3-4-2009
Annex D for 75 Ω coaxial transmission and connected to the SYNC IN connector on the rear panel.
Sync To The SDI Inputs

Sync To The SDI InputsSync To The SDI Inputs
Any of the four SDI inputs may be used to reference the audio outputs. Each two channels of embedded audio in an SDI stream is essentially
compatible with an AES3 word format at a sample frequency of 48 kHz and thus this frequency may be extracted and used as the SRC wordclock
in the same way as an AES3 sync source. If one or more pairs of audio channels in an SDI signal is carrying Dolby-encoded material, the SRC for
that input should be set OFF, and that input should be the sync referenced source.
Use the derived wordclock output as the master sync reference for downstream equipment.
Note:
Note: If using this method, it is important to consider how the remaining three SDI sources synchronise in relation to the sync source. If the

inputs are asynchronous then they should have their SRCs set to ON. This ensures that the audio content will synchronise to the referenced SDI
input.
Note:
Note: Passing Dolby-encoded material through sample rate converters will corrupt the Dolby bit stream.

A: The most commonly used and recommended synchronisation
method for SDI-MADI is slaving it to wordclock via the Ref In
connector. Ensure that wordclock sync has been selected using the
front

Q: What are the Sample Rate Converters for?

Q: What are the Sample Rate Converters for?Q: What are the Sample Rate Converters for?
A: In the traditional sense, Sample Rate Converters (SRC) do as they
say; convert an incoming or outgoing audio source from one sample
rate to another. In the case of SDI-MADI, the SRCs perform two
functions:
a) The sample rate converters compensate for any minor frequency
differences between the incoming SDI 48 kHz and the reference
48 kHz, thus locking the audio to the reference 48 kHz.
b) The sample rate converters are used to phase align the audio
content within the independent SDI sources prior to them being
combined and transmitted as a MADI stream. Unless
synchronising to an SDI source that incorporates Dolby ®
encoded material it is important to ensure that all four SRC
switches are set to ON. If set to OFF it could be possible for
audible clicks to be present on the MADI receiving device. Note:
If SDI-MADI detects that phase alignment between incoming SDI
streams is significantly out (and that all SCRs are set to OFF),
SDI-MADI will mute the MADI output.
Q: When should an SRC switch be set to OFF?
Q: When should an SRC switch be set to OFF?
Q: When should an SRC switch be set to OFF?Q: When should an SRC switch be set to OFF?
A: The only time an SRC switch should be set to OFF is when Dolby ®
content is embedded within the SDI stream. If this situation does
arise then SDI-MADI synchronisation must be set to reference that
specific SDI input. SDI-MADI will then become the sync master
reference source. Ensure that other equipment then synchronises to
the unit’s Wordclock output (WK Out).
Note: only one SRC should be set to OFF at any one time. The
possibility of sync issues could arise if the separate SDI sources are
not phase aligned.

Q: Can SDIQ: Can SDI
A: In the majority of installations SDI-MADI should not be used as a
master sync generator. The only situation that would dictate use as a
master clock reference would be when SDI-MADI is synchronised to an
incoming SDI source that contains Dolby® bit streams. In this
situation the appropriate SDI’s Sample Rate Converter (SRC) switch
should be set to OFF and all other external audio equipment should
be synchronised to the SDI-MADI’s wordclock output (WK Out).
