INTRODUCTION
Thank you very much for purchasing iD or iD dp, Redundant
Multiple Audio Clock Processor, from MUTEC!
About this Manual
The whole manual is related to both versions in general, iD and iD dp.
The individual differences are mentioned in the according sections and
chapters.
The structure of this manual refers to the normal process of installing
id in a standard audio/video studio environment. Thus the chapters are
ergonomically sorted to provide a fast set-up. Before first power-on we
recommend to read the chapters INTRODUCTION and BRIEF INSTRUCTIONS
to get to know the general functionality of id and to reach a fast system
integration.
The following chapters OPERATION and id TECHNOLOGY describe
individual functions which enable the adaption of iD to every studio
environment. The chapters APPLICATION EXAMPLE and APPENDIX include
descriptions of favorable studio set-ups as well as all technical information.
If there are any uncertainties when operating the units which can not be
cleared up by the content of this manual, please feel free to contact your
local dealer or MUTEC directly. All contact details are included in chapter
WARRANTY REGULATIONS located at the beginning of the manual.
General Function Description
Conventional audio clock distributors only distribute and amplify the
incoming reference through different outputs, but the distributed signal
itself will not be further processed. In result, the connected devices
receive jitter-disturbed and unstable clock signals which causes uncertain
synchronization and degraded sound quatlity!
iD works as a clock distributor in an entirely different way. Based on latest
DDS-technology, iD decouples the incoming reference completely to the
output signals. Due to this, the connected devices will receive most stable
and jitter-free clock signals possible at any time – no matter if the incoming
reference consists of high jitter, is instable or partly interrupted. Thus, iD
offers a highly convenient solution to upgrade your studio set-up and
improve your produced sound quality overall!
iD is not only a signal-regenerating distribution amplifier but can also be
used as a master clock reference. In both operation modes iD supports the
industry’s widest range of 36 different audio-related Word Clock rates from
8.0kHz to 24.576MHz. The 3 inputs accept various clock references which
can be distributed through 16 Word Clock (expandable to 20!), 2 AES/EBU
and 2 S/PDIF outputs. Every output pair can transmit a different clock rate
at the same time and a digital varispeed function can be added regardless
of the operation mode. A lot of more special features ensure the use of iD
in every studio environment.
Due to security demands of broadcast houses and professional studios, iD‘s
internal DDS process is designed to supply highest possible failure safety for
all outgoing clock signals in every state of operation. Even in cases of drop
outs or total absence of the reference clock signal, all outgoing signals are
straightforward available without any influences based on the unlimited
freewheel protection mode. Recurring reference signals will be gently re-
synchronized through iD’s efficient SoftRelock functionality without any
phase jumps in the output signals.
The phase relationships of all input and output signals will be observed and
adjusted in real-time automatically, aligned to AES11–1997/2003 und EBU
R83–1996. This process reaches a control accuracy in the nanosecond range.

inputs and INPUT 3 can be synchronized by the synthesizer in a freely confi-
gurable sequence. The impedance of each input is 75 Ω and can be switched
off internally for chaining devices, see the »Switching-off the Termination
of the universal Clock Inputs« section in the APPENDIX.
3 ALARM OUT
The iC-ALARM output is optionally available (item no. 8005-065). Refer to
the EXTENSIONS chapter for a short overview.
4 INPUT3 (AES/EBU)
A balanced digital AES/EBU signal can be applied to this input for synchro-
nizing the internal clock synthesizer. The signal must comply with
AES3 – 1992 (R1997) or AES11 – 1997.
Refer to the OPERATIONS chapter for more
information.
Both input terminals are isolated to ground
to avoid interference from the connected
clock line.
If this does not comply with the electrical
studio purposes, the ground connections of
both inputs could be linked permanently by
setting jumpers on the mainboard. Refer to

5 WORD CLOCK OUT
These outputs send Word Clock and Word Clock x 256 clock rates. Each of
the output pairs can be assigned with a separate clock rate based on the
incoming or internal generated basis clock rate. Associated output pairs are
arranged on top of each other. The individual BNC terminals of an output
pair are marked as A and B; this allows, for example, for a simple documenta-
tion of the connected devices.
6 AES/EBU OUT
These outputs send a balanced digital AES/EBU audio or blank frame signal
compliant with AES3 – 1992 (R1997) and AES11 – 1997. A couple of channel
status bits can be edited. The individual output terminals are marked as
»A« and »B«; this allows, for example, for a simple documentation of the
connected devices.
7 S/PDIF OUT
These outputs send an unbalanced digital S/PDIF audio or blank frame
signal compliant with IEC 60958. A couple of channel status bits can be
edited. The individual output terminals are marked as A and B; this allows,
for example, for a simple documentation of the connected devices.

INSTALLATION
Content of the Box
The unit was packed carefully. Nevertheless we recommend to check the
content directly after opening the package:
1 x iD / iDdp
1 x Power cable, 2 x power cables for iDdp
4 x Rubber feet
1 x Manual
1 x Registration card
Placing the Device
The unit should be set up as closely as possible to the devices to which it
will be connected, so as to avoid excessive cable lengths. Use the 4 rubber
feets enclosed with the appliance and stick them symmetrically on the
bottom side of the unit to protect the enclosure and supporting surface
from being damaged.
The device can be mounted into a standard 19“ rack and will require 1
unit. In this case, the rubber feet cannot be attached. Install the device so
that one unit of rack space is left free both above and below the device to
allow for sufficient ventilation! The mounting depth including the termi-
nals is 240 mm/9.45“ for iD and 280mm/11.02 for iDdp. Another 60 mm/2.4“
should be added for the required cables.
Additional slide-in rails on the rack inside are recommended for safe instal-
lation. This will also avoid long-term mechanical deformation of the housing.
Wiring the Word Clock Interfaces
To allow for synchronization of signals, the interfaces of all devices involved
must be properly connected to each other, so as to ensure a logical signal
flow. Always be sure to connect the Word Clock outputs of iD to the accord-
ing inputs of the devices you wish to synchronize! Cable lengths should be
kept as short as possible to minimize signal losses and/or interference!
For the transmission of Word Clock signals electrical, asymmetrical cables
with a resistance of 75Ω and BNC connectors on both ends are used. Typi-
cally, such cables are marked »RG-59U, RG59B/U«.
Additionally, you should make sure that the Word Clock inputs to be
connected to iD’s outputs have a 75 Ω terminating resistor! Most Word
Clock inputs allow for enabling/disabling the termination with a so-called
»termination-switch«, which may be located on the outside or inside of the
device.
For devices which have no termination of the Word Clock input, e.g. RME
Hammerfall with Word Clock i/o or Alesis BRC, you can use an additional
BNC-T piece to terminate the input. Plug the T piece with its center connec-
tor into the input of the receiving device. Then, connect the cable coming
from iD to one of the lateral connectors, and the other connector of the
BNC-T piece to a 75Ω resistor forming the BNC termination.
Basically, you should avoid »looping through« Word Clock leads by means
of passive BNC-T pieces to preserve the signal quality, as level drops will be
the result. If there is no other way to wire your set-up, please make sure
that all Word Clock inputs (except for the last device in the chain) have
their terminations disabled! In a serial Word Clock chain only the last clock
input should have a termination! Never connect more than three devices in
series to one output!
Never expose the device and
accessories to rain, moisture,
direct sunlight, or excessive heat
produced by radiators, heaters, or spot
lights! Sufficient air circulation in the
environment of the device must be ensured!
!
The condition of the packaging
material and the device should
be checked carefully additionally.
If there are any damages please refer to
SAFETY INSTRUCTIONS, Initial Operation,
and WARRANTY REGULATIONS.
!
Before installing the unit the section
SAFETY INSTRUCTIONS located
at the beginning of this manual
should be read carefully.
!
We recommend using high-grade cables
with a good shielding for your clock signal
leads, in particular, if you need to transmit
Word Clock x 256 (so-called Super Clock)
signals over greater distances. In any case, a
length of max. 10 meters (approx. 30 feet)
should never be exceeded!
It is imperative that the lengths
of all cables connected are largely
the same, as this is the only way to
ensure that all devices will be synchronized
in phase (exception: cable tolerances).
Please make sure that the cable used has a
resistance of 75 Ω, in compliance with the
specifications! If a cable with a different
resistance is used, a dramatic deterioration
of the signal quality can be the result! In
this case, the perfect synchronization of all
devices involved could be impaired.

Wiring the AES/EBU and S/PDIF interfaces
Connect the AES/EBU interfaces with the help of balanced electrical
cables equipped with XLR connectors on both ends. The specifications
stipulate a specific cable resistance of 110Ω (ask your retailer for a confir-
mation of this value when purchasing the cables).
Connect the coaxial S/PDIF interface with the help of unbalanced electri-
cal cables equipped with cinch connectors on both ends. The specifications
stipulate a specific cable resistance of 75Ω (ask your retailer for a confirma-
tion of this value when purchasing the cables).
Since some manufacturers offer optimized
cables for the transmission of digital S/PDIF
and AES/EBU audio signals, it will be a good
idea to ask your retailer for specific cables.
12
Especially when working with high
AES/EBU clock rates well shielded
clock lines are imperative to avoid
increased radiation! Standard cables are nor-
mally useable for clock rates up to 50.0kHz.
Special shielded cable material should be
used for transfer of higher clock rates.

Selecting Menu Pages and setting Functions
The device is fully operated using the display and the four cursor buttons
on the front panel. All display screens have an identical operating structure:
1 Arrows on the left display side for simplifying navigation
2 Appropriate page name on the left display side next to the arrows
3 The upper display line shows the function name
4 The lower display line shows the associated adjustable parameter
Selecting different display pages during
operation will not affect the functionality of
iD. Even changing output function set-tings
will not impede the overall operation!
The arrow orientations refer to the respective cursor buttons.
1 When the two vertical arrows are displayed as normal, pressing the up
and down buttons will move between the individual menu pages.
2 When an arrow pointing to the right is displayed, pressing the right
button (ENTER) will provide access to the adjustable parameter of the
individual functions. With every press of the button, the arrow moves
on to the next parameter of the next function.

3 During this procedure, the two vertical arrows will be inverted, meaning
that the up and down buttons are now used for changing parameter
values and not for moving between menu pages.
4 When the horizontal arrow has been positioned in front of the parameter to
be changed, pressing the up/down buttons will first change to the setting
mode (the arrow will change its shape). Subsequent pressing the ENTER
button will confirm the changes, the arrow will return to its original shape.
Pressing the ENTER key again will then move the arrow to the next parameter.

When iD is running in GENERATOR
mode the first blue LED, LOCK REF 1,
will light and confirm the synchro-
nization of the synthesizer to the internal
reference clock oscillator.
After first switching on, the synthesizer
needs approx. 30 seconds to achieve stable
synchronization. During this process the
system re-locks temporarily (the HOLD
LED and the blue LOCKED REF 1 LED are
lightening alternately). This has no relevance
for system security. The output clocks are
constantly available.
!
INPUT FQ REF1, -2, -3
INPUT REFERENCE, shows an abbreviation of the clock source currently se-
lected incl. its reference slot and its actual rate as a realtime measurement.
As display space is limited, the displayed value is automatically adapted
with regard to the decimal places and the frequency unit as follows:
Hz = hertz
k = kilohertz
M = megahertz
Refer to the »Selecting Clock Sources« section in this chapter for
information on individual sources.
STATUS (function)
Shows the current system status. STATUS provides information on the device
synchronization and possible system errors. Major functionalities are indica-
ted through eight LEDs on the right hand side of the display additionally.
LOCKED (status message)
LOCKED indicates that the system has synchronized to the internal video
reference generator or an externally applied clock signal. At the same time,
the blue LOCK indicator associated with the active clock input (INPUT 1 - 3)
will light.
FQ CHANGE (status message)
FREQUENCY CHANGE indicates that a sync source change is occurring. This
can be a change between two externally applied clock signals or an auto-
matically or manually performed change from an external to an internal
clock source (or vice versa). When the change occurs, the LOCK indicator
of the last clock source used will go dark, and the red HOLD indicator will
light. When the system has locked to the new source, the HOLD indicator
will go dark, and the associated LOCK indicator will light.
HOLD (status message)
HOLD indicates that an externally applied clock signal has either drifted
outside its permitted lock range or is completely lost. In this case, the
system waits for a certain period for the signal to return before automati-
cally changing to the next clock source. This waiting period specified by the
LONEREF parameter on the GLOBAL 1/3 page.
CYCLESYNC (status message)
CYCLE SYNCHRONIZATION indicates that the system is currently perfor-
ming an automatic resynchronization. This function can be disabled on the
REF1–3 page or be enabled manually for individual clock source inputs.
OSCI FAIL (status message)
OSCILLATOR FAILED, indicates that the internal reference clock oscillator has
failed.

The most important clock source
in your studio environment should
always be assigned to REF1! This is
critical for proper completion of the CYCLE-
SYNC setting. Afterwards, the other REF
slots should be assigned with sources in a
hierarchical order.
!
MAIN1LOST (status message)
MAIN 1 LOST indicates that the primary supply voltage or the primary inter-
nal power supply have failed. If this status message is indicated, contact the
technician in charge immediately! The message is displayed only if the iD is
equipped with a redundant power supply (iDdp version, item no. 8015-046).
MAIN2LOST (status message)
MAIN 2 LOST indicates that the secondary supply voltage or the secondary
internal power supply have failed. If this status message is indicated, contact
the technician in charge immediately! The message is displayed only if the iD
is equipped with a redundant power supply (iDdp version, item no. 8015-046).
OUTPUTs (function)
Here, the set clock rates of all outputs are displayed alternately as a
»ticker«. This allows for checking the settings directly with no need for
changing to the relevant menu pages.
The following clock signals or rates are factory defaults:
WORD CLOCK OUT 1 – 8 = 44,1kHz
AES/EBU OUT = 44,1kHz
S/PDIF OUT = 44,1kHz
Selecting the Mode of Operation
This page allows for selecting the general operation mode of iD.
If one of the messages OSCI FAIL,
MAIN1LOST or MAIN2LOST is

OPERATION (function)
This function allows for selecting the mode of operation for iD, in which
the unit is generally working.
GENERATOR (setting)
GENERATOR Selecting the GENERATOR setting synchronizes the synthesizer
to the internal reference clock oscillator. No external reference will be
accepted. The basis clock rate for the multipliers and dividers of all outputs
can be set with »BASIC CLOCK« function, described below.
DISTRIBUTOR (setting)
DISTRIBUTOR Selecting the DISTRIBUTOR setting synchronizes the
synthesizer to an external applied clock source aligned to the settings
on the REF1–3 page. Under function »BASIC CLOCK« the setting »EXT
REFERENCE« will be displayed automatically.
BASIC CLOCK (function)
This function allows for selecting the basis clock rate for the multipliers and
dividers of all outputs. There are three different basis clock rates available.
32.0k, 44.1k, 48.0k (setting)
This setting selects one clock rate as basis clock for all outputs. This basis
clock rate can be multiplied or divided individually for each pair of Word
Clock, AES/EBU and S/PDIF outputs.
EXT REFERENCE (setting)
This setting will be displayed automatically when the operation mode is set
to »DISTRIBUTOR«.
Selecting and activating Clock Sources
The REF1-3 page allows for selecting the clock source of the internal synthe-
sizer. The clock formats supported by iD are listed in the adjacent table. The
factory defaults are REF1 = INTERN, REF2 = NO REF, REF3 = NO REF.
If one of the synchronizable clock sources is selected, the respective signal
format is marked with an index (1 + 2) referring to the two universal clock
MODE page

When applying Word Clock sources, both
pulse and sine signals will be accepted which
allows for processing even heavily slurred
signals.

New References
For special-purpose applications, the range
or number of the sync-clock references can
be extended by means of a software update.
Practically any frequency or frequency
range between 1.0 kHz and 30.0 MHz can be
defined. The only precondition is that the
new clock source can be connected to and
processed by the BNC inputs (INPUT 1 and
INPUT 2) according to their specifications.

If an option supporting new input clock
formats is installed, these will automatically
be implemented by the system and will be
available for selection on the REF1–3 page.
source inputs INPUT 1 and INPUT 2. Thus, the input clock signals can be
routed freely to these two system inputs. The AES format, however, is an
exception as balanced AES/EBU signals can be received by INPUT 3 only.
When selecting clock sources, the system proceeds logically. For example, if
the WCLK1 source (WCLK on INPUT 1) has been selected under REF1, it will
not be available anymore for REF2 and REF3. This means that only sources
with an index of »2«, »AES«, »INTERN«, and »NO REF« can be configured.
Likewise, a clock source programmed for REF2 will not be available for REF3
anymore.
If a clock source is routed to one of the REF slots it has to be activated for
synthesizer synchronization. Therefore the last modified REF slot is dis-
played in the SYNC function menu automatically. Moving the cursor to this
position and pressing the ENTER button will activate the synchronization
process to the new clock source immediately.
REF 1, REF2, REF3 (function)
This function allows for selecting three clock sources supported by the sys-
tem and for assigning them to a clock source slot. The sources will synchro-
nize the system in their numeric sequence (REF1 → REF2 → REF3).
INTERN (setting)
INTERNAL Selecting the INTERN setting synchronizes the synthesizer to the
internal video reference generator that supplies all audio clock signals in
compliance with AES11 and EBU R83. As internal synchronization is the ulti-
mately selected source, no other sources will be left afterwards. Therefore,
when selecting INTERN for REF1, the REF2 and REF3 functions will auto-
matically be assigned with the »NO REF« setting.
WCLK 1, -2 (setting)
The WLCK1, -2 setting allows for synchronizing the synthesizer to all audio-
related Word Clock rates within a range of 8.0…24.576MHz. The applied
clock rate is recognized automatically. Refer to the »Synchronizable and
generatable Clock Rates« section in the appendix for a full list of all clock
rates.
AES (setting)
AES AES allows for synchronizing the synthesizer to all audio-related AES/
EBU rates in a range of 32…192kHz. The applied clock rate is recognized
automatically. Both AES 3 or AES 11 compliant signals can be applied. In ad-
dition, S/PDIF signals can be applied to this input and be used for synchroni-
zation. Refer to the »Synchronizable and Generatable Clock Rates« section
in the appendix for a full list of all clock rates.
AESid 1, -2 (setting)
AESid1, -2 allows for synchronizing the synthesizer to all audio-related AES/
EBU rates in a range of 32…192kHz. The applied clock rate is recognized
automatically. Both AES 3id or AES 11id compliant signals can be applied. In
addition, S/PDIF signals can be applied to this input and be used for syn-
chronization. Refer to the »Synchronizable and Generatable Clock Rates«
section in the appendix for a full list of all clock rates.
S/PDIF1, -2 (setting)
S/PDIF1, -2 allows for synchronizing the synthesizer to all audio-related
S/PDIF rates in a range of 32…192kHz. The applied clock rate is recogni-
zed automatically. Both S/PDIF audio or S/PDIF blank frame signals can be
applied. Refer to the »Synchronizable and Generatable Clock Rates« section
in the appendix for a full list of all clock rates.
NO REF (setting)
Selecting the NO REF setting disables the respective clock-source slot. If, for
example, only two clock sources are connected to the device and REF1 and
REF2 are configured accordingly, assign the NO REF setting to the REF3 slot
in order to disable this slot for the automatic resynchronization function
(see also CYCLESYNC).

SYNC (function)
SYNCHRONIZATION This function allows for manual or automatic synchro-
nization of the synthesizer to selected clock sources assigned to the REF1–3
slots.
SEQSYNC (setting)
SEQUENCE SYNCHRONIZATION This is the default setting when activating
the REF1–3 menu page. It indicates the standard reference synchronization
mode of iCLOCK.
REF 1, REF2, REF3 (setting)
If one of the REF1, REF2, or REF3 parameters is selected and confirmed by
pressing the ENTER button, the synthesizer will immediately synchronize
the clock source assigned to the corresponding REF slot. The output signals
are set or adapted to the new source within the period specified by the
LOCKTIME parameter (see GLOBAL 1/3 page).
CYCLESYNC (setting)
CYCLE SYNCHRONIZATION With this setting, the input circuit querys the three
inputs for clock source reestablishment by cycling from REF1 to REF2 to REF3
and to the internal video reference generator automatically until a source is
available. The system‘s priority is programmed to the first reference slot (REF1).
Refer to »Sequence Synchronization and Cycle Synchronization« section in the
iD TECHNOLOGY chapter for details about SEQSYNC and CYCLESYNC.
Configuring the Word Clock Outputs
The WCLK OUT1–8 display pages allow for configuring the eight wordclock
outputs provided by the iD standard version. Eight output pairs comprising
one top-row and one bottom-row output each are available on the rear
panel. These are numbered as WORD CLOCK OUT1–8. The BNC terminals
making up a pair are marked as »A« and »B«, thus allowing for a simple
documentation of the connected devices.
WCLK - S, WCLK - L (page name)
WORD CLOCK – SINGLE, – LINKED, The »S« and »L« letters indicate the Sing-
le and Linked modes. Refer to the »ADJ-WCLK« parameter on the GLOBAL
3/4 page explained in the OPERATION chapter, »Setting System Functions«
for more information. The factory default is Single mode (– S).
OUT 1 - 8 (page name)
OUT 1 – 8 is the Word Clock out pair that can be configured on the current page.
FREQ (function)
FREQUENCY sets the clock rate of the selected output pair. The factory
default is 44.1 kHz.
8.0kHz...24.576MHz (setting)
Altogether 36 different audio-related clock rates between 8.0 kHz and
24.576 MHz can be selected individually for each Word Clock output pair,
based on a common basis clock rate. The individual rates are shortly descri-
bed under <FORMAT>. Refer to the »Synchronizable and Generatable Clock
Rates« section in the appendix for a full list of all clock rates.
OFF (setting)
OFF disables the selected Word Clock output if not needed.
‹FORMAT› (message)
FORMAT provides information on the output format of the currently selec-
ted Word Clock out pair. This parameter is provided for information purpo-
ses only (this is why it is displayed in brackets.) Setting is made against the
setting of the FREQ parameter. The factory default is WORDCLK.
CYCLESYNC is not available when
the LONEREF function is set to
HOLD (see GLOBAL 1/3 menu page).
!
As the synthesizer is capable of continuously
supplying the adjusted iD output signals,
even a manual clock source change on
an input (by replugging the clock lines) is
supported during operation!
It is not important whether the change occurs,
for example, from a Word Clock signal to
an AES/EBU or S/PDIF signal. The set output
clock multipliers and dividers will not be
altered; only the base rate will be changed
or gradually updated to match the new
source using iD‘s SoftReLock functionality (see
chapter iD TECHNOLOGY).

Due to the internal signal phase corrections
the synthesizer can re-lock temporarily when
switching Word Clock clock frequencies.
This does not affect the output signals or
functionality of iD.
During DISTRIBUTOR operation,
Word Clock rates are set depen-
dently of externally applied clocks!
Example
An externally applied reference clock of
48.0k forces all Word Clock outputs to clock
rates with a basis rate of 48.0k - whereas
individually adjusted multipliers and
dividers are furthermore active!
Input clock rate: 48.0k
WCLK OUT1: 48.0k
WCLK OUT2: 192.0k
WCLK OUT3: 96.0k
...and so on.
After an input reference change:
Input clock rate: 44.1k
WCLK OUT1: 44.1k
WCLK OUT2: 174.4k
WCLK OUT3: 88.2k
...and so on.
!
When a certain Word Clock out pair is not
required, disabling it can be reasonable, for
example, to reduce extra device radiation,
thus improving the EMC conditions in the
studio.
(EMC = electromagnetic compatibility)

WORDCLK (setting)
WORD CLOCK This setting means that the rate is output as set.
SUPERCLK (setting)
The SUPER CLOCK function is available for Word Clock rates of 44.1 or
48 kHz only. It is used for a rate adaptation required for Digidesign Pro-
Tools™ systems (not! ProTools HD™). Accordingly, the 44.1 kHz and 48 kHz
rates are available twice for selection: for both the WORDCLK and the
SUPERCLK, for ProTools™ systems, settings.
LEVEL / TERM (function)
LEVEL / TERMINATION This function allows for adjusting the Word Clock
signal level of the selected output pair and for entirely disabling the
output. The page always displays the output level and the corresponding
internal termination of the output pair. The factory default is 2.6 V/75 R.
2.5 V / 75 R (setting)
With this setting, the Word Clock signal is output with a level of 2.6 V and
an internal termination of 75 Ω.
3.5 V / 22 R (setting)
With this setting, the Word Clock signal is output with a level of 3.5 V and
an internal termination of 22 Ω. This setting is recommended for Word
Clock signals to be transmitted over great distances.
SC adapted (setting)
SUPER CLOCK adapted This is no adjustable setting but a status message
used only for clock rates set to Super Clock. Here, the level cannot be modi-
fied but only be disabled if required (OFF).
Configuring the AES/EBU Outputs
The two AES/EBU outputs can be set to various clock rates. In addition, two
important channel-status bits can be modified.
FREQ (function)
FREQUENCY Sets the clock rate of the AES/EBU output pair. A so-called
AES/EBU clear-frame signal (compliant to AES 11-1997/2003) is generated.
The factory default is 44.1kHz.
16.0...192.0kHz (setting)
Altogether twelve different clock rates between 16.0...192.0 kHz can be
selected for the AES/EBU output pair, dependent on an external reference
or i nternally adjusted basis clock rate. Refer to the »Synchronizable and
Generatable Clock Rates« section in the appendix for a full list of all clock
rates.
DIST (setting)
DISTRIBUTION This setting allows for forwarding an input AES/EBU or
S/PDIF clock signal to the AES/EBU outputs using a hardware bypass. As no
adjustments can be made in this mode, the other functions and parameters
will be hidden. The parameters and functions can only be accessed after the
internal AES/EBU generator has been enabled by selecting a different clock
rate.
In this mode, the synthesizer synchronizes to the input AES/EBU or S/PDIF
signal. Thus, all audio clock signals provided at the other outputs are linked
with phase lock to the input signal.
OFF (setting)
OFF disables the AES/EBU outputs if not needed.
Due to the internal signal phase corrections
the synthesizer can re-lock temporarily
when switching AES/EBU clock frequencies.
This does not affect the output signals or
functionality of iD.

physical parameters of the output terminals
(balanced operation, level, and impedance)
will remain unchanged!
WORDL (function)
WORD LENGTH This function allows for changing the word length stored in
the channel status bits (byte 2, bits 3, 4 and 5) of the clear-frame signal of
the selected AES/EBU output pair. The factory default is 24BITs.
16BITs, 18BITs, 20BITs, 24BITs (setting)
One of four word lengths between 16 and 24Bits are available for selection.
FORMAT (function)
FORMAT This function allows for altering the AES/EBU format stored in the
channel status bits (byte 0, bit 0) of the blank frame signal of the selected
AES/EBU output pair. The factory default is PROF.
PROF, CONS (setting)
PROF, CONS This setting allows for toggling the AES/EBU blank frame signal
between consumer (CONS) and professional (PROF) formats.
Configuring the S/PDIF Outputs
A clock rate can be set for both S/PDIF outputs similarly. In addition, two
important channel-status bits can be modified.
FREQ (function)
FREQUENCY Sets the clock rate of the S/PDIF outputs. A so-called S/PDIF
clear frame signal (in compliance with AES11) is generated. This signal
does not contain any audio information (data bits). The factory default is
44.1kHz.
16.0...192.0kHz (setting)
Altogether twelve different clock rates between 16.0 kHz and 192.0 kHz
can be selected. Refer to the »Synchronizable and Generatable Clock Rates«
section in the appendix for a full list of all clock rates.
DIST (setting)
DISTRIBUTION This setting allows for forwarding an input S/PDIF or
AES/EBU clock signal to the S/PDIF output pair using a hardware bypass.
As no adjustments can be made in this mode, the other functions and
parameters will be hidden. The parameters and functions can only be
accessed after the internal S/PDIF generator has been enabled by selecting
a different clock rate.
In this mode, the synthesizer synchronizes to the input S/PDIF or AES/EBU si-
gnal. Thus, the video and audio clock signals provided at the other outputs
are linked with phase lock to the input signal.
OFF (setting)
OFF disables the AES/EBU outputs if not needed.
WORDL (function)
WORD LENGTH This function allows for changing the word length stored in
the channel status bits of the S/PDIF clear-frame signal.
The factory default is 24BITs.
16BITs, 18BITs, 20BITs, 24BITs (setting)
One of four word lengths between 16 and 24Bits are available for selection.
FORMAT (function)
FORMAT This function allows for altering the S/PDIF format stored in the

48.0k forces the S/PDIF outputs to clock
rates with a basis rate of 48.0k - whereas an
individually adjusted multiplier and divider
is furthermore active!
Input clock rate: 48.0k
S/PDIF outputs: 96.0k
After an input reference change:
Input clock rate: 44.1k
S/PDIF outputs: 88.2k
!
Is the S/PDIF input feeded by an AES/EBU
clock signal, a format and electrical conver-
sion will be done automatically to supply
a standard-compliant signal at the S/PDIF
outputs.
If the professional format is selected,
the physical parameters of the output
terminals (unbalanced operation, level, and
impedance) will remain unchanged!
