Optional system components
The following components may form part of the audio system
and may be ordered separately if required. They may also be
retrofitted to a system at a later time. Separate datasheets
are available for each of the individual components; download
them at
www.cloud.co.uk .
Note that full installation and operation instructions are
supplied with each optional component.
CDI-46 digital interface
The CDI-46 card is an optional accessory which gives the
46-120 additional interface and control capabilities. The
CDI-46 is equipped with both Ethernet and RS-232 ports,
allowing the mixing amplifier’s primary functions to be
controlled from external systems (Crestron, AMX, etc.) using
either protocol. The card also acts as an Ethernet-to-serial
bridge, converting Ethernet commands to other equipment
into RS-232 data. See page 18 and page page 24 for more
details.
The CDI-46 is also fitted with a Cloud Digital Paging interface
(the
CDPM/PM INPUT). This provides the simplest method
of connecting Cloud PM Series Paging Microphones, requiring
only a single standard Cat 5 cable. See page 18 for more
details.

The LM-2 is an active input module which allows a microphone
and a stereo line input in a remote location to be connected
to the 46-120. The faceplate has both phonos and a 3.5 mm
jack socket for connection of the line input, and provides a
convenient access point for the connection of a DJ mixer,
laptop, MP3 player or similar. Mic and line inputs have separate
level controls. A
MIC PRIORITY button activates the Mixer
