Installation
Content of the Box
Your MC-3+ was packed carefully. Nevertheless we recommend to check the content directly after opening the package:
1 x MC-3+
1 x Power cable
1 x USB cable
1 x Manual
If there are any damages visible, please refer to Safety Instructions and Warranty Regulations for further details.
Placing the Device
The unit should be set up as closely as possible to the devices to which it will be connected with to avoid excessive cable
lengths. The four custom-designed case feets include a rubber ring to protect the ground’s surface from being damaged.
The device can be mounted into a standard 19“ rack and will require one unit. Therefore, we offer an optional rack mounting
kit, called MW-05/19. This includes two rack angles which need to be screwed at each side of the device‘s case. Before moun-
ting the device into a 19“ rack, please unscrew the four rubber feets with a suitable screwer. Install the device so that one unit
of rack space is left free both above and below the device to allow for sufficient ventilation! Additional slide-in rails on the
rack inside are recommended for safe installation. This will also avoid long-term mechanical deformation of the housing.
Attention
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!
Wiring the Interfaces
Word Clock
To allow for the synchronization of signals, the interfaces of all devices involved must be properly connected to each other to
ensure a logical signal flow. Always be sure to connect the Word Clock output(s) to the corresponding input(s) of the device(s)
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, unsymmetrical cables with a impedance of 75 Ω and BNC connectors on both ends
are used. Typically, such cables are marked with »RG-59U, RG59B/U«.
Additionally, make sure that the Word Clock input(s) has/have got 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.
AES/EBU
Connect the AES/EBU interfaces with the help of balanced electrical cables equipped with XLR connectors on both ends. The speci-
fications stipulate a specific cable impedance of 110Ω (ask your retailer for a confirmation of this value when buying the cables).
S/P-DIF
Two coaxial S/P-DIF interfaces are available, one based on standard RCA, the other one based on BNC connectors. Connect
these interfaces with help of unbalanced electrical cables equipped with RCA respectively BNC connectors on both ends. The
specifications stipulate a specific cable impedance of 75 Ω for both. Ask your retailer for a confirmation of this value when
buying the cables.
Connect the optical S/P-DIF interface with the help of Toshiba TOSLINK™ compliant optical fiber cables. You can use both
plastic and glass fiber-based cables.
