Technical Note

Connecting an LM-2 to a Line Input on a Z4

Preamble:

The LM-2* is a remote module for use with Cloud host units fitted with an RJ45 Facility Port. It combines

the functions of a remote input connection plate, local audio mixer and a remote control for the host unit's

background music.

Microphone and stereo line inputs are provided, with individual level controls. The stereo input is summed

to mono, and then mixed with the mic input. The LM-2 is designed to be connected to a Facility Port on

the host unit using screened Cat 5 cable and shielded RJ45 connectors. An audio source connected at the

LM-2 module is then routed into the Zone to whose Facility Port it has been connected (normally the one

where the LM-2 is installed).

It is sometimes useful to be able to make the remote audio source available to every Zone supported by

the host unit, rather than just the one local to the LM-2. To achieve this, the balanced audio signal from the

LM-2 needs to be connected to one of the host unit's balanced line inputs instead of a Facility Port; it can

then be selected as the music source for each Zone where it is required, from the host unit's front panel

(or from further LM-2 or RSL-6 Series remote control plates, if they are installed).

This Technical Note describes how to connect an LM-2 module to a balanced line input instead of a Facility Port.

Note that the LM-2 Installation Guide (supplied with each module) should also be referred to while making this

connection.

* The LM-2 is currently available in six style/finish variants: LM-2B, LM-2W, LM-2AB, LM-2AW, LM-2DB and LM-2DW. This Technical Note is

applicable to all variants; the wording "LM-2" is used throughout for brevity.

Parts required:

• 2 x screened RJ45 plugs

• Screened Cat 5 cable of the appropriate length

(host to module location)

• Short length 25 cm (12") of twin-and-screen

audio cable

• 9-way nylon terminal block ("choc-strip") suitable

for 1.5 mm

• Crimp ferrules (white)

• H15 silicone sleeves, 2 mm bore silicone sleeving

• Plastic enclosure to house terminal block with

two cable grommets (recommended but not

essential)

(Note that as the cable carries analogue audio, only screened

Cat 5 cable and shielded RJ45 connectors should be used.)
