2 LM-1: Installation & User Guide
1 Safety Notes
The Cloud LM-1 remote input panel must be fitted by a technically qualified person. Do not
tamper with any part of the equipment unless you are experienced or qualified to do so.
Before working on any piece of Cloud equipment turn the power off and remove the mains
supply cable from the rear of the unit
2 General
The Cloud LM-1 is a remote active input panel that has been designed for use in conjunction
with the Z4 and Z8 range of venue mixers and also the 46/50 integrated mixer amplifier.
With facilities for a line level music input and balanced microphone input, it has similar
features to the AE-1 panel with some enhancements that allow it to be used in scenarios that
demand a greater versatility.
The LM-1 can be used for any application where local connection and control of microphone
and/or line level signals is required. The prime application is an entertainment zone that may
have the need to connect DJ’s or Karaoke systems etc, directly into the house system. In
addition to the separate level controls for music and microphone signals, the operator can
select microphone over music priority. This priority operates both the local music signals
and mixer music signals simultaneously.
The LM-1 has an extra feature that is unique within the active remote panel range in that it
also incorporates an RSL-6. This allows the remote control of the zone mixer Music Select
and Music Level controls.
3 LM-1A
The LM-1A is available for the American market. It has identical operation to the LM-1 but
has been designed to fit a 1 1/2” deep, US three-gang box. The front panel dimensions of
the LM-1A are 4 1/2” × 6 3/8”.
