Crestron SWE-8 Sonnex™ Multiroom Audio Expansion Switcher, 8 Zone
Setup
Sonnex Link Wiring
Crestron recommends using Crestron DM-CBL-8G (sold separately) or high-quality
CAT5e shielded twisted-pair cable for Sonnex Link connections between the SWE-8
and the SWAMP-24X8 or S-EXT1-S.
NOTE: Shielded connectors such as the DM-8G-CONN (sold separately) must be
used.
DM-CBL-8G wire can carry Sonnex Link signals up to 200 feet (61 meters).
Installation
Ventilation
The SWE-8 should be used in a well-ventilated area. The venting holes should not be
obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the environment may be greater
than the room ambient temperature. Contact with thermal insulating materials should
be avoided on all sides of the unit.
Rack Mounting
The SWE-8 can be mounted in a rack or stacked with other equipment. Two “ears”
are provided with the SWE-8 so that the unit can be rack mounted. These ears must
be installed prior to mounting. Complete the following procedure to attach the ears
to the unit. The only tool required is a #1 or #2 Phillips screwdriver.
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
 When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
 If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: Four “feet” are provided with the SWE-8 so that if the unit is not rack
mounted, the rubber feet can provide stability when the unit is placed on a flat
surface or stacked. These feet should be attached prior to the hookup procedure.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
