Safety Instructions
General Instructions
To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture,
direct sunlight or excessive heat from sources such as radiators or spotlights. No user service-
able parts are inside. Repair and maintenance must be carried out by qualified personnel au-
thorized by MUTEC GmbH! The unit has been designed for operation in a standard domestic
environment. Do NOT expose the unit and its accessories to rain, moisture, direct sunlight or
excessive heat produced by such heat sources as radiators or spotlights! The free flow of air
inside and around the unit must always be ensured.
Initial Operation
Prior to the initial operation of the unit, the appliance, its accessories and packaging must
be inspected for any signs of physical damage that may have occurred during transit. If the
unit has been damaged mechanically or if liquids have been spilled inside the enclosure, the
appliance may not be connected to the mains or must be disconnected from the mains im-
mediately! If the unit is damaged, please do NOT return it to MUTEC GmbH, but notify your
dealer and the shipping company immediately, otherwise claims for damage or replacement
may not be granted.
If the device is left in a low-temperature environment for a long time and then is moved to
a room-temperature environment, condensation may occur on the inside and the exterior.
To avoid short-circuits and flashovers, be sure to wait one or two hours before putting the
device into operation.
Power Supply
The device contains a self-adapting wide-range power supply supporting the majority
of global standard line voltages within a range of 90…250 V, with no need for making
adjustments. Make sure that your line-voltage source provides a supply voltage within the
specified range. In addition, make sure that the device is properly grounded via the local
electric installation.
Please use the enclosed power cord (see packaging) to connect the unit to the mains. Switch
the unit off before you attempt to connect it to the mains. Connect the power cord to the
unit, then to a standard 3-pin mains outlet. To draw the power cord, never pull on the cable
but on the mains plug!
The unit must be grounded during operation!
For information on the power-inlet wiring, refer to the »Wiring of connectors« section in the
appendix. Disconnect the device from the mains when not using it for an extended period!

Introduction
Thank you very much for buying the MC-3+ Smart Clock, a Synchronizable Digital Audio Master Clock Generator, from MUTEC!
General Description
The new MUTEC MC-3+ Smart Clock is especially designed to improve the acoustical quality of digital audio devices in two
ways: At first by clocking external devices with ultra-low jitter Word Clock signals and secondly by aggressively re-clocking
incoming digital audio signals. Therefore, we have developed a totally new clocking technology, which we are calling the
»MUTEC 1G-Clock«. That means in practice, we are running – for the first time in the audio industry – an audio clock synthesis
process with a basis clock rate in the gigahertz area! Together with new ultra-low noise power supplies and new PCB design
rules aligned to high-speed communication technologies, the MUTEC 1G-Clock brings jitter and electrical noise down to unique
low levels, which leads to unprecedented transparency in your audio recordings.
Also working as a clock distributor and unlike other products, the MC-3+ effectively regenerates incoming clock signals to
higher purity as the signal source. Thus, the MC-3+ enables to improve already existing clock systems and helps to raise the
standard of sound reproduction in every studio environment.
Additionally, the MC-3+ Smart Clock locks to so-called atomic clocks or GPS receivers to raise its timing accuracy to the
highest possible level. For use during live events or in mobile trucks, the MC-3+ features an anytime fail-safe clock generation
in every operation mode. Entering the hold-over mode and re-synchronization of returning clock references is carried out so
smoothly that live recordings surely will not affected.
The new MUTEC MC-3+ Smart Clock and its unique 1G-Clock Technology add with most aggressive jitter reduction a significant
improvement in sound to most studio set-ups, while ensuring flawless synchronization of connected devices at any time!

8 »MAINS IN«, Power Switch + Mains connector (IEC)
This is the main switch for switching the device on and off. Connect the supplied IEC power cable to the device‘s mains con-
nector. Make sure that the power switch is turned off before connecting the device to your power source finally. Line voltages
within the range of 90…260 V with a frequency of 50 or 60 Hz can be applied. The internal power supply will automatically
make all necessary adjustments.
Read the Safety Instructions at the beginning of this manual!

Operation
»HOLD«
This red LED lights when the external reference clock signal is interrupted or lost. The frequency synthesizer of the MC-3+ kee-
ps generating all output signals continuously, based on the last incoming clock rate. Thus, your studio set-up receives non-in-
terrupted clock supply, regardless if a valid external referecne signal is present, unstable or lost. Re-synchronization is carried
out without affecting any of the outputs signals critically.
»AUDIO«
This red LED lights when a valid AES3/11 or S/P-DIF optical or coaxial digital audio reference signal is detected at the corre-
sponding input.
CLOCK IN
This area displays the clock rate of
the incoming clock or digital audio
reference signal. The following basis
reference clock rates are supported and
will be analyzed.
Generic Functions
There are two additional functions which influence the working of your whole MC-3+:
Front Panel lock out + LED shut down
When pressing both front panel keys together at one time, all LEDs will shut down except the »POWER« and »LOCK« LEDs.
Additionally, the functions of both keys are also blocked to prevent unauthorized operation, which is important during e.g. live
events.
During that state of operation, pressing only one of both keys let every appropriate LED light according the device‘s settings as
long as the key is pressed. Thus, you can check easily the device‘s settings without unlocking the device finally.
To reactivate the keys and the LEDs, please press both keys for apperox. four seconds until all LEDs light again.
Factory Reset
You can reset the operating system of your MC-3+ to the initial status by switching on the unit while pressing the »MENU«
key simultaneously.

Inside View – Word Clock Termination
When the MC-3+ Smart Clock is shipped, the BNC-based Word Clock input connector is
terminated internally with 75 Ω. Therefore, one jumper is put on two pins - Position 2 - of
the 3-pin socket JP1.
