through the rear. Situations where the air flows in a circular direction around and
through a PRO Series unit must be prevented. Midas recommends that racks with
fully opening front and rear doors are used.
• Rack mount supports Always secure the rear of the PRO Series units to the rack
via their rear rack mount support brackets. These brackets are fitted to every PRO
Series unit and are recommended for use in touring applications. The rack mount
support fixing hole centres are at a depth of approximately 395 mm from the front
panel.
Note: The rack mount support fixing hole centre depth from the front panel of the
DN9696 Recorder may be slightly different.
• Handles on rack case You must ensure that there are sufficient external handles
fitted to the rack casing to enable the rack to be manoeuvred easily and safely, and
by the number of personnel suitable for the task. Also, these handles must be fit for
purpose.
• Clearance at rear of units Ensure an adequate clearance at the rear of the units
to provide sufficient free space to enable the cables to achieve their minimum bend
radius.
• Securing the cables
tidied using lacing bars and cable ties. This should provide optimum access to the
rear of the units for connecting other cables, switching the units on/off etc., and also
to give maximum visibility of the units' LEDs for determining communication status,
link status, condition of audio etc.
Note: The above requirements also apply to any other Midas and Klark Teknik units,
such as the DL431 Mic Splitter.

Wiring instructions

Important:
The control centre and all of the DLnn1 units have Volex locking type plugs
fitted on their supplied mains cables, which plug into their mains IEC
connectors. When fitted properly the Volex plug locks into place, preventing it
working loose, or being inadvertently knocked loose or pulled out. For details
of how to fit/remove a Volex plug, see "Power" on page xvii.
Basically, to connect the system equipment together all you have to do is to connect
the control centre to the DL371 Audio System Engine using the Cat 5e or fibre optic
snake; the racks units should already be connected together when you receive them.
>> To connect the PRO Series Control Centre to the DL371 Audio System
Engine
1
At the rear of the PRO Series Control Centre, connect the fibre-optic or copper
snakes to the optical or copper connectors, respectively, in the snake X and
snake Y sections.
2
At the rear of the DL371 Audio System Engine, connect the two snakes to the
appropriate connectors (optical or copper) in the snake X and snake Y
sections.
Caution!
Never combine units in the same rack that have been designed for
a ventilation air flow direction other than that designed for the
Midas units. To avoid this, we recommend that any non-Midas
units are housed separately.
We recommend that the cables at the rear of the units be
