X16 MADI Merge Unit Revision MM2006-1
Introduction
Thank you for purchasing the X16 MADI Merge Unit from Cadac
Electronics plc.
The Cadac X16 is a 1U rack mount unit capable of receiving up to
four optical MADI (Multitrack Audio Digital Interface) streams from
Cadac’s M16 Remote Controlled Microphone Amplifiers, or other
devices. Each MADI stream received from an M16 consists of 16 required audio channels (Ch1 - Ch16). The X16 combines these channels in order to provide a single combined MADI output stream, in
both optical and coaxial formats. This output st ream can comprise of
a maximum of 64 channels at 48kHz sampling frequency, or 32
channels at 96kHz sampling frequency.
The X16 is designed to operate in Standard and Extended MADI
modes, enabling both 56/28 and 64/32 channel operation.
Output connectivity is provided in the form of four paired MADI outputs. Each pair comprising both optical (SC) and coaxial (BNC) interfaces. The X16 is therefore capable of pro viding up to eight MADI
output streams derived from the combination of the 4 x 16 channels
sourced from Cadac M16 or other systems. This provides the functionality of an 8-way MADI distribution system.
iii
By offering multiple MADI outputs, the X16 becomes the heart of a
centralised digital distribution syst em. In the case of an M16/X16 Remote Mic-Pre/Stage Rack system, it provides a powerful digital audio distribution system, enabling multiple microp hone sources to be
routed throughout a fixed installation or live venue completely within
the digital domain from a single 1U rack mount enclosure.
An additional mode enables the X16 to o perate independently of Cadac M16 units, providing up to four 1 in/2 out MADI distribution amplifiers. This feature enables four independen t optical MADI streams
(of up to 64 channels each) to be made ava ilable on both an optica l
and coaxial output connector, and is an ideal choi ce for an y spa ce
conscious installation requiring multiple MADI interface conversions
or additional routing capability.
Finally, the X16 incorporates a very practical wordclock distri bution
system. Not only can the X16 slave to an external wordclock sync
source, it also incorporates a very stable temperature compensated
inbuilt wordclock generator, enabling the X16 to become the wordclock master in a digital audio system. Four additional wordclock
outputs are also provided as standard, to enable the di stribution of
stable and buffered sync sources in a star topology. Th is avoids the
need to daisy-chain wordclock signals from device to device.
We trust that the Cadac X16 will bring many years of satisfaction and
thank you for your patronage.

2 Important information
2.1 Unpacking
The first thing to do when receiving a new X16 is to confirm that the
unit hasn’t been damaged in transit and that all it ems are contained
within the packaging.
The X16 packaging contains:
■ 1 x X16
■ 1 x IEC mains cable (either fitted with UK or US style plug, or
unwired depending on country of use)
■ 1 x operations manual
Please retain packaging until all items are accounted for and found
to be operating correctly.
2-11
Revision MM2006-1 X16 MADI Merge Unit
2-12
2.2 Operational Considerations
AC mains voltage
The X16 is intended for use throughout the world and therefore the
internal power supply allows operation through the followin g AC
mains voltages:
Mains voltage: 90v - 250v AC
Mains frequency: 50/60Hz
AC mains connection
The rear panel of the X16 houses the AC mains inlet on an IEC style
connector. The mains cable supplied with the X16 is also fit ted with
a moulded IEC connector. Excluding UK and USA models, no plug
has been fitted to this mains lead, therefore this will need to be wired
(see 1.1.Mains Cable). Obtain professional advice from a qualified
electrician if unsure.
2.3 Cleaning
Before cleaning the X16, make sure the un it is switched of f an d t h e
mains plug is removed from the socket.
Only use a mildly damp cloth to clean the X16. Never use any domestic or commercial cleaning agents as these can cause damage
to external surfaces and components.
2.4 Installation
When fixing the X16 into any 19” rack mount frame, take into account the stresses that can be exerted on the rack ears if they are
the only means of support. Damage to the chassis could especially
occur during transportation if the X16 is not suppor ted on rails within
a flight case. Cadac strongly recommends that as well as fixing the
X16 to the frame via the rack ears, support rails also be employed.

3.3 Connecting up your X16
3.3.1 Mains power
Make sure that your IEC power connector is wired co rrectly (see 1.1
Mains Cable).
Fit the IEC cable to the rear power connector on the X16, making
sure that it is fitted securely and the cable is stress free.
3.3.2 MADI Inputs
The four MADI input connections on the X16 use optical SC housings and are located on the rear panel of the unit. See 3.2 X16 Rear
Panel. If using the X16 with multiple M16 devices then optical cables
will be routed from the transmit (Tx) SC housing of the M16 to one
of the MADI input connectors of the X16.
Carefully remove the cover from the duplex SC housings on t he X16
rear panel. This will reveal two optical connection points. One is labelled In# (where # represents inputs 1, 2, 3 or 4) and the other is
labelled Outputx (where x represents outputs A, B, C or D.)
NOTE: Take care to store the connector cover in a safe place.
Take the optical cable from the M16, or other device, an d carefully
insert the mating connector into the receive (In#) connect or housing
on the X16, making sure that the locating key on the cable connector
is aligned with the locating slot on the receive (In#) connector housing. Once correctly inserted, the optical connector should lock into
place. Repeat this process for each input required.
Note: Always work in a sequential order starting from MADI In1 and
working your way to MADI In4. It is not a requirement however, to
use all four input connectors.
NOTE: Confirm that the optical connector is secure ly locked in
place and that it is correctly located i n the receive (Inx) connec tor.
3.3.3 MADI Outputs
The X16 provides four optical SC connectors and four coaxial BNC
connectors on the rear panel for output connectivity. See 3.2 X16
Rear Panel. These are grouped into pairs with one SC connector
and one BNC connector being available for each output group. Spe cific operation of each output group (OutputA, OutputB, OutputC and
OutputD) is dependant on the selected operating mode of the X16.
See 3.5 X16 MADI Merge Operation.
To connect to the optical SC housings, repeat the procedure explained in 3.3.2 MADI Inputs, but fit t he optical SC connectors in one
of the Outputx connector housings.
X16 MADI Merge Unit Revision MM2006-1
If using coaxial cables within the MADI system, then these should be
fitted with male BNC connectors. Fix these onto the appropriate mating BNC connector on the X16 rear panel and lock them into place
by giving the connector shell a quarter turn (clockwise.)
3.3.4 Wordclock Master/Slave
A single BNC connector located on the X16 rear panel can operate
either as a wordclock master or slave. See 3. 2 X16 Rear Panel. The
choice of whether this connector is going to act as a maste r or slave
is dependent on the overall system design and how all the digital
equipment within the audio system will be synchronised. If the X16
is to slave to an external workclock source then connect a 75 Ohm
coaxial cable, preferably directly from the wordclock master, to the
X16 Wordclock Master/Slave BNC connector and lock it into place
by giving the connector shell a quarter turn (clockwise.)
If the X16 is to act as the wordclock master then conne ct the 75 Ohm
coaxial cable and run it to the wordclock input of the re ce ivin g de vice.
3-15
NOTE: Do not forget to set the X16 to the correct synchronisation mode. See 3.4 Configuring the X16.
NOTE: If the X16 is either the last in a chain of devices, or the only unit to receive an external wordclock synchronisation source, then the 75 Ohm termination will need to b e switched into circuit. See 3.3.4 Wordclock Master/Slave
3.3.5 Buffered Wordclock Outputs 1 - 4
The X16 is designed to provide four M16s, or other devices, with
high quality wordclock sources designed to improve overall audio
performance. These wordclock outputs connect directly to the
M16’s, or other device’s wordclock input connectors.
NOTE: If the device receiving the X16 wordclock source is fitted
with just one BNC connector, make sure that it is set to Slave.
NOTE: If no 75 Ohm termination switch is provided on the receiving device then a 75 Ohm load should be f itted to a BNC ‘T’
piece.
Connect a 75 Ohm coaxial cable to each of the wordclock outputs on
the X16 (making sure to securely lock them int o pl ace by giving t he
connector shells a quarter turn clockwise ) and repeat the process for
the wordclock inputs on the receiving devices.

3.4 Configuring the X16
3.4.1 Power On
Power on the X16 using the main power switch located on the rear
panel adjacent to the IEC connector. The front panel Power LED will
illuminate once power is received to the unit.
NOTE: A set power-on sequence is not required for the X16 to
operate properly.
3.4.2 MADI Mode
Before the X16 can properly merge audio data, it is import ant to configure it correctly to meet the configurations o f the transmitting audio
devices.
NOTE: If the MADI configuration of the transmitting devices differ to the that of the X16 then the X16 will not merge audio data.
3-17
■ Select the sampling rate. Press the Sample Rate switch to
select either 48kHz, or 96kHz operation. LED indicati on is provided to confirm selection.
■ Select the MADI format. Press the MADI Mode switch to select
either Standard (Std) or Extended (Ext) MADI format. LED indi-
cation is provided to confirm selection.
The Standard MADI protocol follows the origins of the format and caters for 56 audio channels at 48kHz. The more recent Extended
MADI format allows for 64 channels to be streamed down one cab le
at 48kHz sampling. When operating at the higher sampling f requency of 96kHz, the available channel coun t is effe ctively halved, therefore providing 28 channels in Sta ndard MADI mode and 32 channels
when operating in Extended MADI mode. You will be able to confirm
the number of available channels by looking at the Audio Channels
Out section.
■ Audio Channels Out. This section provides visual confirmation
of the number of channels that the X16 is configured to work
with. One of the four LEDs will illuminate to confirm channel
operating conditions. These are: 28; 32; 56 and 64 channels.
■ Select the Processing Mode. Press the Processing Mode
switch to select either Merge or Thru. LED indication is provided
to confirm selection.
Merge configures the X16 to Merge the first 16 channels of each
connected MADI input together. See 3.5 X16 MADI Merge Operation
for further details.
Thru configures the X16 to pass up to four com plete MADI str eam s
directly to a four pairs of output connectors (one SC and one BNC)
without affecting the MADI stream itself. See 3.5.3 MADI Thru Mode
for further details.

3-18
■ Select Wordclock Master or Slave. Press the Wordclock switch
to select either Master or Slave. LED indication is provided to
confirm selection. See 3.5.4 Wordclock Synchronisation for fur-
ther details on how this operates.
■ Select whether Wordclock termination is required if receiving an
external clock source. If it is, then press in the 75 Ohm termination switch (located on th e rear panel) and the corresponding
front panel LED will illuminate.
NOTE: Wordclock termination is only required if the X16 is syn chronising to external wordclock and it is either a) the only device connected to the master clock sou rce, or b) at the end of a
daisy-chain of connected devices (not best practice!)
If all settings correspond with the connected MADI devices and everything is synchronised properly, the corresponding green MADI In
LEDs located on the far left of the front panel (see 3.1 X16 Front
Panel) will illuminate. If problems do occur then these LEDs will pro-
vide status indication to enable quick trouble shootin g. For further information concerning see 3.5.5 X16 LED Error Indication.
X16 MADI Merge Unit Revision MM2006-1
3.5 X16 MADI Merge Operation
The following chapters describe in detail the operation of the X16
when configured to merge multiple MADI streams together.
3.5.1 48kHz Mode MADI Merge
In this mode the X16 can receive up to four optical MADI streams
sourced from a maximum of four Cadac M16s, o r other devices. The
first 16 channels of each MADI stream (channels 1 to channels16)
are derived from the sixteen channels of each M16. Subsequent
channels within each of the MADI streams (channels 17 and above )
are not required and ignored.
The X16 combines the first sixteen channels of each MADI input t ogether, ascending from Input 1 (In1) through to Input 4 (In4), therefore creating a single stream of 64 channels (when operat ing in
Extended MADI mode.) This combined MADI stream is made available to all eight MADI output connectors.
3-19
In Standard 56 channel MADI mode, the last 8 channels from In put
4 (In4) - M16 Unit 4/channels 9 through 16 - will not be combined into
the MADI output stream.
Revision MM2006-1 X16 MADI Merge Unit
3-20
3.5.2 96kHz Mode MADI Merge
In this mode, the X16 can receive up to four optical MADI streams
sourced from a maximum of four Cadac M16s, or other devices.
However, the maximum number of channels within a MADI stream
is 32, therefore in 96kHz operation the X16 will provide two completely independent outputs for two pairs of M16 devices.
In Standard 28 channel MADI mode , the last 4 channels from MADI
Input 2 (In2) and MADI Input 4 (In4) will not be combined into the
MADI output streams.
MADI output pairs OutputA and OutputB are sourced from the
combination of Input 1 (In1) and Input 2 (In2)
MADI output pairs OutputC and OutputD are sourced from the
combination of Input 3 (In3) and Input 4 (In4)
X16 MADI Merge Unit Revision MM2006-1
3.5.3 MADI Thru Mode
In addition to providing the MADI Merge facilities, the X16 also has
the ability of providing a Thru mode. T his fe at ur e en ab le s the ope rator to route up to four inde pendent and complete optical MA DI input
streams directly to the four MADI output pairs. This provides both optical and coaxial MADI conversion, while also providing a two way
output split for each of the four MADI input streams.
MADI Thru Mode is selected from the front panel via t he Processing
Mode switch.
3-21
3.5.4 Wordclock Synchronisation
The X16 is fitted with five wordclock BNC connectors for synchronisation purposes.
■ One BNC providing Wordclock Master/Slave connectivity
Operation of the Wordclock Master/Slave BNC is controlled via the
front panel Wordclock switch.
Wordclock Master.
The internally generated wordclock conforms well within Grade 2
specifications (being +/- 3.5ppm).
The wordclock output circuitry driving this BNC connector is capable
of driving long cable lengths with minimum degr ad ation o f t he wor dclock signal. This allows the X16 to be the system master reference
clock source, while also allowing connection to remote equipment,
such as digital consoles. These may be some distance away from
the M16/X16, if located stage-side for example.
Revision MM2006-1 X16 MADI Merge Unit
3-22
Wordclock Slave.
When a valid wordclock signal is received, the X16 will generate its
own clean internal synchronisation clock from the incoming reference in order to improve overall performance.
If the incoming wordclock does not equate to the sam ple rate selected via the X16 front panel then the X16 will not output any audio and
a visual warning will be presented on the front panel. See 3.5.5 X16
LED Error Indication
A 75 Ohm termination switch is provided adjacent to the Wordclock
Master/Slave BNC connector. This should be enabled if an external
wordclock source is not passed on to another devic e.
■ Four BNC Wordclock Outputs
These are buffered wordclock outputs to be used primarily for the
purpose of connecting up to four M16s, or other MADI devices, in a
star topology to improve synchronisation performance. In slave
mode, the four BNC outputs follow the incoming wordclock reference
signal, while in master mode, the four BNC outputs follow the ma in
internally generated wordclock signal.
X16 MADI Merge Unit Revision MM2006-1
3.5.5 X16 LED Error Indication
In addition to providing general configura tio n fe ed ba ck of the X16
modes, specific LEDs on the X16 front panel also provide a level of
system status/error information.
Incoming Wordclock Error.
When the wordclock slave LED and currently select ed sample rate
LED both flash, the incoming wordclock frequency is differen t to the
selected frequency on the X16.
When the wordclock slave LED and both sample rate LEDs flash,
the incoming wordclock frequency is neither 48kHz or 96kHz. It can
also indicate that wordclock is not present/connected to the X16,
while the X16 is configured in slave mode.
3-23
MADI Input Status.
Four MADI In LEDs provide a constant indication of the condition of
the overall incoming MADI streams.
If communication from the transmitting device is operating cor rectly,
the related LED will be constantly illuminated.
A flashing LED indicates that the sampl e-rate within the par ticular incoming MADI stream does not match that set on the X16. Make sure
that sample rate is identical for both the X16 and the tran sm ittin g
MADI device.
If the LED is not illuminated there is either no transmitting device
connected to that particular input, or the transmitting device is not
powered. If that particular input is meant to be operating, check co nnections and the status of the transmitting MADI device.

LED Status Indication
LED Status Check
APP-29
One or more of the MADI In green
LEDs are not illuminated.
One, or more, of the MADI In green
LEDs is flashing.
Wordclock Slave and chosen sample rate LEDs are flashing.
Wordclock Slave and both 48kHz
and 96kHz sample rate LEDs flash.
This generally indicates that no external MADI
device is connected to the MADI Input connector.
Check connections and also the operating status of
the MADI transmitting device
A flashing MADI In LED indicates that the MADI In
source sample rate associated with the flashing LED
differs from that selected on the X16. Make sure that
the chosen sample rates on the X16 and transmitting
MADI device are identical.
The incoming wordclock frequency differs to that set
on the X16. Make sure that these are set to be identical.
The incoming wordclock is neither 48kHz or 96kHz.
It can also indicate that external wordclock is either
not present or not connected. Make sure that the
external wordclock is connected and configured to
transmit at either 48kHz or 96kHz. Sample rates
between devices should be configured to be identical.
