INSTALLATION

Content of the Box

The unit was packed carefully. Nevertheless we recommend to check the

content directly after opening the package:

1 x MC-4

1 x Power cable

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

160 mm/6.7“. 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 ADAT

, AES/EBU and S/PDIF interfaces

ADAT

Connect the optical ADAT™ interfaces with the help of TOSLINK™-compli-

ant optical fiber cables. Here, you can use both plastic and glass fiber-based

cables. When using plastic fiber cables, lengths of 10 meters should not be

exceeded, so as to ensure the reliable transmission of signals. Glass fiber

cables can transfer data reliably even over greater distances.

AES/EBU

Connect the AES/EBU interface with the help of an electrical 25-cond. cable

equipped with 25-pin D-Sub connectors. The specifications stipulate a spe-

cific cable resistance of 110 Ω. When purchasing the cable ask your retailer

for a confirmation that the cable will perform flawlessly in your specific

application.

Connect the coaxial S/PDIF interfaces with help of unbalanced electrical

cables equipped with cinch connectors on both ends. The specifications

stipulate a specific cable resistance of 75 Ω. Ask your retailer for a confirma

tion of this value when purchasing the cables.

Wiring the Word Clock Interfaces

To allow for the 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 output of the MC-4

to the corresponding input of the device you wish to synchronize. Cable

lengths should be kept as short as possible to minimize signal losses and/or

interferences!

For the transmission of Word Clock signals electrical, unsymmetrical cables

with a resistance of 75 Ω 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 input to be con

nected to the MC-4’s output 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.

Before installing the unit the section

SAFETY INSTRUCTIONS located

at the beginning of this manual

should be read carefully.

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.

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!

MUTEC offers optical cables of various

lengths that have been specifically tested for

the transmission of ADAT™ signals. Ask your

local dealer for those cables!

We advise you not to buy 25pin

D-Sub cables from your computer

retailer! Even though such cables

may look similar to 25pin D-Sub AES/EBU

cables, they may be wired differently!

MUTEC assumes no liability for damages

resulting from the use of improperly wired

cables!

Especially when working with high AES/EBU

clock rates well shielded cables are imperative

to avoid increased radiation! Standard cables

are normally useable for clock rates up to

50.0kHz. Special shielded cable material

should be used for transfer of higher clock

rates.

Please make sure that the cable

used has a resistance of 75 Ω! 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 could be impaired.

We recommend using high-grade cables with

a good shielding. A length of max. 10 meters

(approx. 30 feets) should not be exceeded!
