INTRODUCTION

Thank you very much for purchasing iCLOCK or iCLOCK dp, Redundant
Multiple Clock Synthesizer & Video Reference Generator, from MUTEC!

About this Manual

The whole manual is related to both versions in general, iCLOCK and
iCLOCK dp. The individual differences are mentioned in the according
sections and chapters.

The structure of this manual refers to the normal process of installing
iCLOCK 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 iCLOCK and to reach a fast
system integration.

The following chapters OPERATION and iCLOCK TECHNOLOGY describe
individual functions which enable the adaption of iCLOCK 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.

The grey boxes contain supplementary
information for the corresponding sections
in the text columns. The content of the
individual box refers to the description in
the text column beside the box.

Boxes which contain a triangle
with an exclamation mark should

be read carefully! These include
additional information which are of major
importance for the functional descriptions in
the text column.

General Function Description

iCLOCK is a synchronizable, high-precision clock generator which is
designed to be the reference in digital audio and video studios as well
as broadcast and television stations. Based on a totally new concept
of frequency generation, developed by MUTEC, the unit offers an
unchallanged flexibility for synchronization of different devices to one
house clock. On this occasion iCLOCK breaks traditional, unflexible forms
of chaining input and output signals and allows for the first time their
completely free combination and scaleability.

iCLOCK‘s philosophy is addressed to provide the highest possible failure
safety for all outgoing clock signals which is needed especially for
broadcast stations or centralized clock distribution systems. With regards
to this functionality up to 3 independent external references can be auto­detected and locked in a user-defined sequence without any phase-jumps
or interruptions in the outgoing signals. This applies also to external
clock frequency changes, e.g. from 44.1kHz to 48.0kHz or reference clock
changes, e.g. from video to GPS or AES11. Even if all external references
are lost, iCLOCK synthesizes the outgoing clock signals based on the
last incoming frequency constantly. If the absent reference clock returns
the synthesizer will lock gradually again based on iCLOCK’s SoftReLock
functionality which ensures interruption-free adjustments of all outgoing
clock signals. In this case a continous clock supply for all connected devices
is guaranteed during any operation mode.

For todays audio/video productions a precision synchronisation of the used
audio and video equipment is imperative. To reach the highest value of
accuracy the involved clock signals need to be synchronized and converted
without any phase drift. Therefore iCLOCK offers a unique, automatically
working signal management which observes the phase relationships of all
input and output signals and takes care of adjustments aligned to
AES11-1997/2003 and EBU R83-1996.

Using DDS-coupled frequency generation and latest DSP-based filtering
technologies in combination with an extremely low-jitter clock basis of
< 10ps (RMS), iCLOCK eliminates the jitter of incoming reference signals
completely. This ensures highest possible jitter attenuation for all outgoing
clock signals. As a result the synchronization of connected devices is much
more reliable and the sound quality of every AD/DA converter will be
increased significantly.

Differences between Software V2.10 and V2.11

Both versions include the preset management as new functionality, which
was inquired by several professonal MUTEC customers (see page 28).
Using software V2.10 or V2.11 depends on the alarm interface you have
already installed or you plan to install. Software V2.10 supports only the
older interface iC-ALARM (ordering no. 8005- 056), whereas software
V2.11 supports only the new iC-AL ARM/GPI (ordering no. 8005-066).

The iC-ALARM/GPI interface offers same basis functionality like the iC­ALARM, but the new iC-ALARM/GPI interface allows for switching over the
different presets via its GPIO function (see page 31, 32).

5 PAL/NTSC VIDEO OUT
SD bi-level PAL and NTSC composite video sync signals are sent from these
outputs. After installing the optional P/NVSG-02 video sync generator (item
no. 8010-010), a separate video format can be assigned to each output pair.
Associated output pairs are arranged on top of each other.
If a HD tri-level sync signal is applied to a reference input, the incoming
reference can be distributed through the PAL/NTSC video outputs.
The individual BNC terminals of an output pair are marked as A and B; this
allows, for example, for a simple documentation of the connected devices.

for a full list of all Word Clock, AES/EBU and
S/P-DIF clock rates that can be generated.

For detailed specifications on all terminals,
refer to the »Pin assignment of the
Connectors« and »Technical Data« sections
in the APPENDIX.

These outputs send Word Clock, Word Clock x 256 signals and film / video
frame / field clock rates. Each of the output pairs can be assigned with a sepa­rate 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 documentation of the connected devices.

7 + 8 AES/EBU OUT1, AES/EBU OUT2
These outputs send a balanced digital AES/EBU audio or blank frame signal
compliant with AES3 – 1992 (R1997) and AES11 – 1997. Each of the output
pairs can be assigned with a separate clock rate, and the channel status bits
can be edited individually. The rear-panel outputs are marked as AES OUT 1
and AES OUT 2, the individual output terminals as »A« and »B«; this allows,
for example, for a simple documentation of the connected devices.

9 S/P-DIF OUT
These outputs send an unbalanced digital S/P-DIF audio or blank frame
signal compliant with IEC 60958. The 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 iCLOCK / iCLOCK dp
1 x Power cable, 2 x power cables for iCLOCK dp
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 termi­nals is 240 mm/9.45“ for iCLOCK and 280mm/11.02 for iCLOCK dp. Another
60 mm/2.4“ should be added for the required cables.

Additional slide-in rails on the rack inside are recommended for safe instal­lation. This will also avoid long-term mechanical deformation of the housing.

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.

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!

Before Powering Up

Wiring the Word Clock and Video 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 iCLOCK to the
according 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 or video signals electrical, asymmetrical
cables with a resistance of 75Ω and BNC connectors on both ends are used.
Typically, such cables are marked »RG-59U, RG59B/U«.

Additionally, you should make sure that the Word Clock or video inputs to
be connected to iCLOCK’s outputs have a 75 Ω terminating resistor! Most
Word Clock or video 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 connec­tor into the input of the receiving device. Then, connect the cable coming
from iCLOCK 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!

Clock Cable Lengths

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.

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!

Wiring the AES/EBU and S/P-DIF interfaces

Cables for High Clock Rates

Especially when working with high

AES3/-11 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.

Since some manufacturers offer optimized
cables for the transmission of digital S/P-DIF
and AES3/-11 signals, it will be a good idea
to ask your retailer for specific cables.

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 confir­mation of this value when purchasing the cables).

Connect the coaxial S/P-DIF interface with the help of unbalanced elec tri­cal cables equipped with cinch connectors on both ends. The specifications
stipulate a specific cable resistance of 75Ω (ask your retailer for a confirma­tion of this value when purchasing the cables).

GENERAL OPERATION

Menu Structure

The entire menu structure is based on the logical flow of events when deploying the iCLOCK in a standard audio/video-studio
environment. Therefore, starting with the menu main page, the menu pages have an ergonomically structured sequence and can
thus be called successively by repeatedly pressing the up button.
