INSTALLATION
Content of the Box
The unit was packed carefully. Nevertheless we recommend to check the
content directly after opening the package:
1 x FORMAT CHANGER advanced
1 x Power cable
4 x Rubber feets
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. When the unit is installed in a rack, the rubber feets
should not be used to save space!
For 19 rack installation MUTEC offers an optional set of rack ears
(MW-01/19 order no. 8020-005). Install the device so that one unit of rack
space is left free above the device to allow for sufficient ventilation! The
mounting depth including the terminals is 180 mm/7.07.
Another 150 mm/5.9 should be added for the required cables.
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 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 logi-
cal signal flow. Always be sure to connect the Word Clock output of the
FORMAT CHANGER advanced to the corresponding input of the devices 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 inputs to be con-
nected to the FORMAT CHANGER advanceds output have a 75
Ω
termi-
nating 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 or Alesis BRC, you can use an additional
BNC-T piece to terminate the input. Plug the T piece with its center connec-
tor into the input of the receiving device. Then, connect the cable coming
from the FORMAT CHANGER advanced 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!
Additionally the condition of the
packaging material and the device
should be checked carefully. If there
are any damages please refer to SAFETY
INSTRUCTIONS, Initial Operation, and
WARRANTY REGULATIONS.
!
Before installing the unit finally
the section SAFETY INSTRUCTIONS
located at the beginning of this
manual should be read.
!
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 feets)
should never be exceeded!
