LM-2 Installation Guide v1.1 3
Introduction
The LM-2 is a remote module for use with all Cloud products fitted with a Facility Port, including:
•
Z4 MK3 and Z8 MK3 Zone Mixers
•
Z4 MK4 and Z8 MK4 Zone Mixers
•
46-120 and 46-120 MEDIA Zone Mixing Amplifiers
NOTE: Unless specifically stated otherwise, all references
to “LM-2” in this Installation Guide can be taken to apply
to all LM-2 mechanical and cosmetic variants.
The LM-2 module combines the functions of a remote input connection plate, local audio mixer and a remote control for the
host unit’s background music.
Inputs for both a microphone and a stereo line signal (for a local music source) are provided, with individual level controls. The
stereo channels are summed to mono, and then mixed with the mic input.
The remote control facilities are equivalent to those on a Cloud RSL-6 remote control module, and allow selection of background
music source and level control for the host’s Zone to which the LM-2 is connected. (Note that the 46-120 and 46-120
MEDIA
have a single Facility Port, for Zone 1 only.)
The LM-2 is connected to the host unit’s Facility Port by a single screened Cat 5 cable with shielded RJ45 connectors. A link
connector is provided to permit multiple LM-2s to be installed in the same Zone.
