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-8 or MC-8.1
1 x Power cable
4 x Rubber feet
1 x Manual
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, using the MW-05/19 rack mounting kit (MUTEC item no. 8020-035). In
this case, the rubber feet cannot be attached. Please make sure that there
is enough space on the right and left hand side of the device to enable
sufficient air convection! The mounting depth including the terminals is
160 mm/6.7“. Another 60 mm/2.4“ should be added for the required 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-8
or MC-8.1 to the corresponding input of the device you wish to synchro-
nize. 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, R G59B/U«.
Additionally, you should make sure that the Word Clock input to be con-
nected to the MC-8’s or MC-8.1’s output has 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, Alesis BRC or M-Audio ProFire Light-
bridge, 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 the MC-8’s or MC-8.1’s Word Clock
output to one of the lateral connectors, and the other connector of the
BNC-T piece to a 75
Ω
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!
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!
!
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. A length of max. 10 meters
(approx. 30 feets) should not be exceeded!
